Button Hidden and clickable when press "enter" in not a form - javascript

I'm using ajax to submit a form without refreshing the page.
The problem is, I want to submit the form by pressing enter. If I was using a form field it would be easy, cause I only had to put,
hidden="true"
here is my code:
<div id="form">
<input type="text" id="text" />
<button hidden="true" id="submit_button"></button>
</div>
Jquery Code
$(document).ready(function() {
document.getElementById("submit_button").onclick= function(){submit_form()}
/*
ajax request to submit.php
*/;
});

You can listen to keyDown event.
$('#text').keydown(function (e){ //OR on keyup
if(e.keyCode == 13){
submit_form()
}
})

Try this:
$(document).keypress(function (e) {
var key = e.which;
if(key == 13) // the enter key code
{
submit_form()
}
});

I don't know if I understand, but if you want to can add the keypress trigger into the inbox:
$('#text').keydown(function(e){
if (e.keyCode == 13){
// Do as you need, ex:
$('#form').submit();
return false;
}
else return true;
});

Prevent submit form when focus is on input [duplicate]

How do you prevent an ENTER key press from submitting a form in a web-based application?
[revision 2012, no inline handler, preserve textarea enter handling]
function checkEnter(e){
e = e || event;
var txtArea = /textarea/i.test((e.target || e.srcElement).tagName);
return txtArea || (e.keyCode || e.which || e.charCode || 0) !== 13;
}
Now you can define a keypress handler on the form:
<form [...] onkeypress="return checkEnter(event)">
document.querySelector('form').onkeypress = checkEnter;
Here is a jQuery handler that can be used to stop enter submits, and also stop backspace key -> back. The (keyCode: selectorString) pairs in the "keyStop" object are used to match nodes that shouldn't fire their default action.
Remember that the web should be an accessible place, and this is breaking keyboard users' expectations. That said, in my case the web application I am working on doesn't like the back button anyway, so disabling its key shortcut is OK. The "should enter -> submit" discussion is important, but not related to the actual question asked.
Here is the code, up to you to think about accessibility and why you would actually want to do this!
$(function(){
var keyStop = {
8: ":not(input:text, textarea, input:file, input:password)", // stop backspace = back
13: "input:text, input:password", // stop enter = submit
end: null
};
$(document).bind("keydown", function(event){
var selector = keyStop[event.which];
if(selector !== undefined && $(event.target).is(selector)) {
event.preventDefault(); //stop event
}
return true;
});
});
Simply return false from the onsubmit handler
<form onsubmit="return false;">
or if you want a handler in the middle
<script>
var submitHandler = function() {
// do stuff
return false;
}
</script>
<form onsubmit="return submitHandler()">
//Turn off submit on "Enter" key
$("form").bind("keypress", function (e) {
if (e.keyCode == 13) {
$("#btnSearch").attr('value');
//add more buttons here
return false;
}
});
You will have to call this function whic will just cancel the default submit behaviour of the form. You can attach it to any input field or event.
function doNothing() {
var keyCode = event.keyCode ? event.keyCode : event.which ? event.which : event.charCode;
if( keyCode == 13 ) {
if(!e) var e = window.event;
e.cancelBubble = true;
e.returnValue = false;
if (e.stopPropagation) {
e.stopPropagation();
e.preventDefault();
}
}
The ENTER key merely activates the form's default submit button, which will be the first
<input type="submit" />
the browser finds within the form.
Therefore don't have a submit button, but something like
<input type="button" value="Submit" onclick="submitform()" />
EDIT: In response to discussion in comments:
This doesn't work if you have only one text field - but it may be that is the desired behaviour in that case.
The other issue is that this relies on Javascript to submit the form. This may be a problem from an accessibility point of view. This can be solved by writing the <input type='button'/> with javascript, and then put an <input type='submit' /> within a <noscript> tag. The drawback of this approach is that for javascript-disabled browsers you will then have form submissions on ENTER. It is up to the OP to decide what is the desired behaviour in this case.
I know of no way of doing this without invoking javascript at all.
In short answer in pure Javascript is:
<script type="text/javascript">
window.addEventListener('keydown', function(e) {
if (e.keyIdentifier == 'U+000A' || e.keyIdentifier == 'Enter' || e.keyCode == 13) {
if (e.target.nodeName == 'INPUT' && e.target.type == 'text') {
e.preventDefault();
return false;
}
}
}, true);
</script>
This only disables the "Enter" keypress action for input type='text'. Visitors can still use "Enter" key all over the website.
If you want to disable "Enter" for other actions as well, you can add console.log(e); for your your test purposes, and hit F12 in chrome, go to "console" tab and hit "backspace" on the page and look inside it to see what values are returned, then you can target all of those parameters to further enhance the code above to suit your needs for "e.target.nodeName", "e.target.type" and many more...
See my detailed answer for a similar question here
I've always done it with a keypress handler like the above in the past, but today hit on a simpler solution. The enter key just triggers the first non-disabled submit button on the form, so actually all that's required is to intercept that button trying to submit:
<form>
<div style="display: none;">
<input type="submit" name="prevent-enter-submit" onclick="return false;">
</div>
<!-- rest of your form markup -->
</form>
That's it. Keypresses will be handled as usual by the browser / fields / etc. If the enter-submit logic is triggered, then the browser will find that hidden submit button and trigger it. And the javascript handler will then prevent the submision.
All the answers I found on this subject, here or in other posts has one drawback and that is it prevents the actual change trigger on the form element as well. So if you run these solutions onchange event is not triggered as well. To overcome this problem I modified these codes and developed the following code for myself. I hope this becomes useful for others.
I gave a class to my form "prevent_auto_submit" and added the following JavaScript:
$(document).ready(function()
{
$('form.prevent_auto_submit input,form.prevent_auto_submit select').keypress(function(event)
{
if (event.keyCode == 13)
{
event.preventDefault();
$(this).trigger("change");
}
});
});
I've spent some time making this cross browser for IE8,9,10, Opera 9+, Firefox 23, Safari (PC) and Safari(MAC)
JSFiddle Example: http://jsfiddle.net/greatbigmassive/ZyeHe/
Base code - Call this function via "onkeypress" attached to your form and pass "window.event" into it.
function stopEnterSubmitting(e) {
if (e.keyCode == 13) {
var src = e.srcElement || e.target;
if (src.tagName.toLowerCase() != "textarea") {
if (e.preventDefault) {
e.preventDefault();
} else {
e.returnValue = false;
}
}
}
}
stopSubmitOnEnter (e) {
var eve = e || window.event;
var keycode = eve.keyCode || eve.which || eve.charCode;
if (keycode == 13) {
eve.cancelBubble = true;
eve.returnValue = false;
if (eve.stopPropagation) {
eve.stopPropagation();
eve.preventDefault();
}
return false;
}
}
Then on your form:
<form id="foo" onkeypress="stopSubmitOnEnter(e);">
Though, it would be better if you didn't use obtrusive JavaScript.
Preventing "ENTER" to submit form may inconvenience some of your users. So it would be better if you follow the procedure below:
Write the 'onSubmit' event in your form tag:
<form name="formname" id="formId" onSubmit="return testSubmit()" ...>
....
....
....
</form>
write Javascript function as follows:
function testSubmit(){
if(jQuery("#formId").valid())
{
return true;
}
return false;
}
(OR)
What ever the reason, if you want to prevent the form submission on pressing Enter key, you can write the following function in javascript:
$(document).ready(function() {
$(window).keydown(function(event){
if(event.keyCode == 13) {
event.preventDefault();
return false;
}
});
});
thanks.
To prevent form submit when pressing enter in a textarea or input field, check the submit event to find what type of element sent the event.
Example 1
HTML
<button type="submit" form="my-form">Submit</button>
<form id="my-form">
...
</form>
jQuery
$(document).on('submit', 'form', function(e) {
if (e.delegateTarget.activeElement.type!=="submit") {
e.preventDefault();
}
});
A better solution is if you don't have a submit button and you fire the event with a normal button. It is better because in the first examlple 2 submit events are fired, but in the second example only 1 submit event is fired.
Example 2
HTML
<button type="button" onclick="$('#my-form').submit();">Submit</button>
<form id="my-form">
...
</form>
jQuery
$(document).on('submit', 'form', function(e) {
if (e.delegateTarget.activeElement.localName!=="button") {
e.preventDefault();
}
});
In my case, this jQuery JavaScript solved the problem
jQuery(function() {
jQuery("form.myform").submit(function(event) {
event.preventDefault();
return false;
});
}
You will find this more simple and useful :D
$(document).on('submit', 'form', function(e){
/* on form submit find the trigger */
if( $(e.delegateTarget.activeElement).not('input, textarea').length == 0 ){
/* if the trigger is not between selectors list, return super false */
e.preventDefault();
return false;
}
});
How about:
<asp:Button ID="button" UseSubmitBehavior="false"/>
Add this tag to your form - onsubmit="return false;"
Then you can only submit your form with some JavaScript function.
Please check this article How to prevent ENTER keypress to submit a web form?
$(“.pc_prevent_submit”).ready(function() {
$(window).keydown(function(event) {
if (event.keyCode == 13) {
event.preventDefault();
return false;
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form class=”pc_prevent_submit” action=”” method=”post”>
<input type=”text” name=”username”>
<input type=”password” name=”userpassword”>
<input type=”submit” value=”submit”>
</form>
You can trap the keydown on a form in javascript and prevent the even bubbling, I think. ENTER on a webpage basically just submits the form that the currently selected control is placed in.
This link provides a solution that has worked for me in Chrome, FF, and IE9 plus the emulator for IE7 and 8 that comes with IE9's developer tool (F12).
http://webcheatsheet.com/javascript/disable_enter_key.php
Another approach is to append the submit input button to the form only when it is supposed to be submited and replace it by a simple div during the form filling
Simply add this attribute to your FORM tag:
onsubmit="return gbCanSubmit;"
Then, in your SCRIPT tag, add this:
var gbCanSubmit = false;
Then, when you make a button or for any other reason (like in a function) you finally permit a submit, simply flip the global boolean and do a .submit() call, similar to this example:
function submitClick(){
// error handler code goes here and return false if bad data
// okay, proceed...
gbCanSubmit = true;
$('#myform').submit(); // jQuery example
}
I Have come across this myself because I have multiple submit buttons with different 'name' values, so that when submitted they do different things on the same php file. The enter / return button breaks this as those values aren't submitted.
So I was thinking, does the enter / return button activate the first submit button in the form?
That way you could have a 'vanilla' submit button that is either hidden or has a 'name' value that returns the executing php file back to the page with the form in it.
Or else a default (hidden) 'name' value that the keypress activates, and the submit buttons overwrite with their own 'name' values.
Just a thought.
How about:
<script>
function isok(e) {
var name = e.explicitOriginalTarget.name;
if (name == "button") {
return true
}
return false;
}
</script>
<form onsubmit="return isok(event);">
<input type="text" name="serial"/>
<input type="submit" name="button" value="Create Thing"/>
</form>
And just name your button right and it will still submit, but text fields i.e. the explicitOriginalTarget when you hit return in one, will not have the right name.
If none of those answers are working for you, try this. Add a submit button before the one that actually submits the form and just do nothing with the event.
HTML
<!-- The following button is meant to do nothing. This button will catch the "enter" key press and stop it's propagation. -->
<button type="submit" id="EnterKeyIntercepter" style="cursor: auto; outline: transparent;"></button>
JavaScript
$('#EnterKeyIntercepter').click((event) => {
event.preventDefault(); //The buck stops here.
/*If you don't know what this if statement does, just delete it.*/
if (process.env.NODE_ENV !== 'production') {
console.log("The enter key was pressed and captured by the mighty Enter Key Inceptor (⌐■_■)");
}
});
This worked for me.
onkeydown="return !(event.keyCode==13)"
<form id="form1" runat="server" onkeydown="return !(event.keyCode==13)">
</form>
Here's how I'd do it:
window.addEventListener('keydown', function(event)
{
if (event.key === "Enter" && event.target.tagName !== 'TEXTAREA')
{
if(event.target.type !== 'submit')
{
event.preventDefault();
return false;
}
}
});
put into javascript external file
(function ($) {
$(window).keydown(function (event) {
if (event.keyCode == 13) {
return false;
}
});
})(jQuery);
or somewhere inside body tag
<script>
$(document).ready(function() {
$(window).keydown(function(event) {
alert(1);
if(event.keyCode == 13) {
return false;
}
});
});
</script>
I had the same problem (forms with tons of text fields and unskilled users).
I solved it in this way:
function chkSubmit() {
if (window.confirm('Do you want to store the data?')) {
return true;
} else {
// some code to focus on a specific field
return false;
}
}
using this in the HTML code:
<form
action="go.php"
method="post"
accept-charset="utf-8"
enctype="multipart/form-data"
onsubmit="return chkSubmit()"
>
In this way the ENTER key works as planned, but a confirmation (a second ENTER tap, usually) is required.
I leave to the readers the quest for a script sending the user in the field where he pressed ENTER if he decide to stay on the form.

Textarea enter keypress not working because of form submit enter prevention

I have a form in which I've used the following code to prevent the form being submitted on the press of 'Enter'.
<script>
$(document).ready(function() {
$(window).keydown(function(event){
if(event.keyCode == 13) {
event.preventDefault();
return false;
}
});
});
</script>
As a result, the 'Enter' key is not working in any textarea input. I can't enter a new line because of the body function. How do I solve this?
<textarea name='description' placeholder="Any other information (optional)"</textarea>
I have find solution.
You prevent enter key on all the form element. Just add some tweak to your code and its done. Just skip prevention of enter key when your focus is on textarea. See below code :
$(document).ready(function() {
$(window).keydown(function(event){
if(event.target.tagName != 'TEXTAREA') {
if(event.keyCode == 13) {
event.preventDefault();
return false;
}
}
});
});
To prevent the form from submitting, try this instead:
$("form").submit(function(e){
e.preventDefault();
}

How can I disable the ENTER key on my textarea?

<form name='qform'>
<textarea name='q' rows='3' cols='60' wrap='hard' id='q' onkeydown="if (event.keyCode == 13) document.getElementById('clickit').click()"></textarea>
<input type='button' value='search' id='clickit' onclick="get();">
</form>
I have this form... it doesn't have a submit button because I am using jquery and under this form is a div area where the results will be shown. It is a search engine that does not have an input box but instead has a textarea. This is because it will be a multiple word searcher.
The problem is that if I press enter, the query is submitted and everything is ok ... but the focus on textarea goes down one line and that is a problem for me.
Basically I want the enter to have that one function only(submit) end nothing else.
$(document).ready(function() {
$('textarea').keypress(function(event) {
if (event.keyCode == 13) {
event.preventDefault();
}
});
});
Why not just use <input type="text"> if you don't want multiple lines? You mentioned it will be a "multiple word searcher". Why does this require a <textarea>?
Update
Try this
$('textarea').bind('keypress', function(e) {
if ((e.keyCode || e.which) == 13) {
$(this).parents('form').submit();
return false;
}
});
In the jquery function, use event.preventdefault and next do what you like.
For example
<script>
$("a").click(function(event) {
event.preventDefault();
//Do your logic here
});
</script>
http://api.jquery.com/event.preventDefault/
Pure javascript:
document.addEventListener('keypress', function (e) {
if (e.keyCode === 13 || e.which === 13) {
e.preventDefault();
return false;
}
})

Prevent form submission on Enter key press

I have a form with two text boxes, one select drop down and one radio button. When the enter key is pressed, I want to call my JavaScript function, but when I press it, the form is submitted.
How do I prevent the form from being submitted when the enter key is pressed?
if(characterCode == 13) {
// returning false will prevent the event from bubbling up.
return false;
} else{
return true;
}
Ok, so imagine you have the following textbox in a form:
<input id="scriptBox" type="text" onkeypress="return runScript(event)" />
In order to run some "user defined" script from this text box when the enter key is pressed, and not have it submit the form, here is some sample code. Please note that this function doesn't do any error checking and most likely will only work in IE. To do this right you need a more robust solution, but you will get the general idea.
function runScript(e) {
//See notes about 'which' and 'key'
if (e.keyCode == 13) {
var tb = document.getElementById("scriptBox");
eval(tb.value);
return false;
}
}
returning the value of the function will alert the event handler not to bubble the event any further, and will prevent the keypress event from being handled further.
NOTE:
It's been pointed out that keyCode is now deprecated. The next best alternative which has also been deprecated.
Unfortunately the favored standard key, which is widely supported by modern browsers, has some dodgy behavior in IE and Edge. Anything older than IE11 would still need a polyfill.
Furthermore, while the deprecated warning is quite ominous about keyCode and which, removing those would represent a massive breaking change to untold numbers of legacy websites. For that reason, it is unlikely they are going anywhere anytime soon.
Use both event.which and event.keyCode:
function (event) {
if (event.which == 13 || event.keyCode == 13) {
//code to execute here
return false;
}
return true;
};
event.key === "Enter"
More recent and much cleaner: use event.key. No more arbitrary number codes!
NOTE: The old properties (.keyCode and .which) are Deprecated.
const node = document.getElementsByClassName("mySelect")[0];
node.addEventListener("keydown", function(event) {
if (event.key === "Enter") {
event.preventDefault();
// Do more work
}
});
Modern style, with lambda and destructuring
node.addEventListener("keydown", ({key}) => {
if (key === "Enter") // Handle press
})
Mozilla Docs
Supported Browsers
If you're using jQuery:
$('input[type=text]').on('keydown', function(e) {
if (e.which == 13) {
e.preventDefault();
}
});
Detect Enter key pressed on whole document:
$(document).keypress(function (e) {
if (e.which == 13) {
alert('enter key is pressed');
}
});
http://jsfiddle.net/umerqureshi/dcjsa08n/3/
Override the onsubmit action of the form to be a call to your function and add return false after it, ie:
<form onsubmit="javascript:myfunc();return false;" >
A react js solution
handleChange: function(e) {
if (e.key == 'Enter') {
console.log('test');
}
<div>
<Input type="text"
ref = "input"
placeholder="hiya"
onKeyPress={this.handleChange}
/>
</div>
So maybe the best solution to cover as many browsers as possible and be future proof would be
if (event.which === 13 || event.keyCode === 13 || event.key === "Enter")
Here is how you can do it using JavaScript:
//in your **popup.js** file just use this function
var input = document.getElementById("textSearch");
input.addEventListener("keyup", function(event) {
event.preventDefault();
if (event.keyCode === 13) {
alert("yes it works,I'm happy ");
}
});
<!--Let's say this is your html file-->
<!DOCTYPE html>
<html>
<body style="width: 500px">
<input placeholder="Enter the text and press enter" type="text" id="textSearch"/>
<script type="text/javascript" src="public/js/popup.js"></script>
</body>
</html>
Below code will add listener for ENTER key on entire page.
This can be very useful in screens with single Action button eg Login, Register, Submit etc.
<head>
<!--Import jQuery IMPORTANT -->
<script src="https://code.jquery.com/jquery-2.1.1.min.js"></script>
<!--Listen to Enter key event-->
<script type="text/javascript">
$(document).keypress(function (e) {
if (e.which == 13 || event.keyCode == 13) {
alert('enter key is pressed');
}
});
</script>
</head>
Tested on all browsers.
A jQuery solution.
I came here looking for a way to delay the form submission until after the blur event on the text input had been fired.
$(selector).keyup(function(e){
/*
* Delay the enter key form submit till after the hidden
* input is updated.
*/
// No need to do anything if it's not the enter key
// Also only e.which is needed as this is the jQuery event object.
if (e.which !== 13) {
return;
}
// Prevent form submit
e.preventDefault();
// Trigger the blur event.
this.blur();
// Submit the form.
$(e.target).closest('form').submit();
});
Would be nice to get a more general version that fired all the delayed events rather than just the form submit.
A much simpler and effective way from my perspective should be :
function onPress_ENTER()
{
var keyPressed = event.keyCode || event.which;
//if ENTER is pressed
if(keyPressed==13)
{
alert('enter pressed');
keyPressed=null;
}
else
{
return false;
}
}
A little simple
Don't send the form on keypress "Enter":
<form id="form_cdb" onsubmit="return false">
Execute the function on keypress "Enter":
<input type="text" autocomplete="off" onkeypress="if(event.key === 'Enter') my_event()">
Using TypeScript, and avoid multiples calls on the function
let el1= <HTMLInputElement>document.getElementById('searchUser');
el1.onkeypress = SearchListEnter;
function SearchListEnter(event: KeyboardEvent) {
if (event.which !== 13) {
return;
}
// more stuff
}
<div class="nav-search" id="nav-search">
<form class="form-search">
<span class="input-icon">
<input type="text" placeholder="Search ..." class="nav-search-input" id="search_value" autocomplete="off" />

<input type="button" id="search" value="Search" class="btn btn-xs" style="border-radius: 5px;">
</form>
</div>
<script type="text/javascript">
$("#search_value").on('keydown', function(e) {
if (e.which == 13) {
$("#search").trigger('click');
return false;
}
});
$("#search").on('click',function(){
alert('You press enter');
});
</script>

Cross Browser Solution
Some older browsers implemented keydown events in a non-standard way.
KeyBoardEvent.key is the way it is supposed to be implemented in modern browsers.
which
and keyCode are deprecated nowadays, but it doesn't hurt to check for these events nonetheless so that the code works for users that still use older browsers like IE.
The isKeyPressed function checks if the pressed key was enter and event.preventDefault() hinders the form from submitting.
if (isKeyPressed(event, 'Enter', 13)) {
event.preventDefault();
console.log('enter was pressed and is prevented');
}
Minimal working example
JS
function isKeyPressed(event, expectedKey, expectedCode) {
const code = event.which || event.keyCode;
if (expectedKey === event.key || code === expectedCode) {
return true;
}
return false;
}
document.getElementById('myInput').addEventListener('keydown', function(event) {
if (isKeyPressed(event, 'Enter', 13)) {
event.preventDefault();
console.log('enter was pressed and is prevented');
}
});
HTML
<form>
<input id="myInput">
</form>
https://jsfiddle.net/tobiobeck/z13dh5r2/
Use event.preventDefault() inside user defined function
<form onsubmit="userFunction(event)"> ...
function userFunction(ev)
{
if(!event.target.send.checked)
{
console.log('form NOT submit on "Enter" key')
ev.preventDefault();
}
}
Open chrome console> network tab to see
<form onsubmit="userFunction(event)" action="/test.txt">
<input placeholder="type and press Enter" /><br>
<input type="checkbox" name="send" /> submit on enter
</form>
I used document on, which covers dynamically added html after page load:
$(document).on('keydown', '.selector', function (event) {
if (event.which == 13 || event.keyCode == 13) {
//do your thang
}
});

Submitting a form on 'Enter' with jQuery?

I have a bog-standard login form - an email text field, a password field and a submit button on an AIR project that's using HTML/jQuery. When I hit Enter on the form, the entire form's contents vanish, but the form isn't submitted. Does anyone know if this is a Webkit issue (Adobe AIR uses Webkit for HTML), or if I've bunged things up?
I tried:
$('.input').keypress(function (e) {
if (e.which == 13) {
$('form#login').submit();
}
});
But that neither stopped the clearing behavior, or submitted the form. There's no action associated with the form - could that be the issue? Can I put a javascript function in the action?
$('.input').keypress(function (e) {
if (e.which == 13) {
$('form#login').submit();
return false; //<---- Add this line
}
});
Check out this stackoverflow answer:
event.preventDefault() vs. return false
Essentially, "return false" is the same as calling e.preventDefault and e.stopPropagation().
In addition to return false as Jason Cohen mentioned. You may have to also preventDefault
e.preventDefault();
Don't know if it will help, but you can try simulating a submit button click, instead of directly submitting the form. I have the following code in production, and it works fine:
$('.input').keypress(function(e) {
if(e.which == 13) {
jQuery(this).blur();
jQuery('#submit').focus().click();
}
});
Note: jQuery('#submit').focus() makes the button animate when enter is pressed.
Return false to prevent the keystroke from continuing.
Is there any reason you have to hook and test for the enter key?
Couldn't you simply add a
<input type="submit" />
to your form and have it naturally be submitted when enter is pushed? You could even then hook the form's onsubmit action and call a validation function from there if you wanted...
You could even use the onsubmit as a test to see if your form is being submitted, but it won't work if you call form.submit().
Here's a way to do this as a JQuery plugin (in case you want to re-use the functionality):
$.fn.onEnterKey =
function( closure ) {
$(this).keypress(
function( event ) {
var code = event.keyCode ? event.keyCode : event.which;
if (code == 13) {
closure();
return false;
}
} );
}
Now if you want to decorate an <input> element with this type of functionality it's as simple as this:
$('#your-input-id').onEnterKey(
function() {
// Do stuff here
} );
You can also simply add onsubmit="return false" to the form code in the page to prevent the default behaviour.
Then hook (.bind or .live) the form's submit event to any function with jQuery in the javascript file.
Here's a sample code to help:
HTML
<form id="search_form" onsubmit="return false">
<input type="text" id="search_field"/>
<input type="button" id="search_btn" value="SEARCH"/>
</form>
Javascript + jQuery
$(document).ready(function() {
$('#search_form').live("submit", function() {
any_function()
});
});
This is working as of 2011-04-13, with Firefox 4.0 and jQuery 1.4.3
This is my code:
$("#txtMessage").on( "keypress", function(event) {
if (event.which == 13 && !event.shiftKey) {
event.preventDefault();
$("#frSendMessage").submit();
}
});
Also to maintain accessibility, you should use this to determine your keycode:
c = e.which ? e.which : e.keyCode;
if (c == 13) ...
Just adding for easy implementation. You can simply make a form and then make the submit button hidden:
For example:
<form action="submit.php" method="post">
Name : <input type="text" name="test">
<input type="submit" style="display: none;">
</form>
I use now
$("form").submit(function(event){
...
}
At first I added an eventhandler to the submit button which produced an error for me.
I found out today the keypress event is not fired when hitting the Enter key, so you might want to switch to keydown() or keyup() instead.
My test script:
$('.module input').keydown(function (e) {
var keyCode = e.which;
console.log("keydown ("+keyCode+")")
if (keyCode == 13) {
console.log("enter");
return false;
}
});
$('.module input').keyup(function (e) {
var keyCode = e.which;
console.log("keyup ("+keyCode+")")
if (keyCode == 13) {
console.log("enter");
return false;
}
});
$('.module input').keypress(function (e) {
var keyCode = e.which;
console.log("keypress ("+keyCode+")");
if (keyCode == 13) {
console.log("Enter");
return false;
}
});
The output in the console when typing "A Enter B" on the keyboard:
keydown (65)
keypress (97)
keyup (65)
keydown (13)
enter
keyup (13)
enter
keydown (66)
keypress (98)
keyup (66)
You see in the second sequence the 'keypress' is missing, but keydown and keyup register code '13' as being pressed/released.
As per jQuery documentation on the function keypress():
Note: as the keypress event isn't covered by any official specification, the actual behavior encountered when using it may differ across browsers, browser versions, and platforms.
Tested on IE11 and FF61 on Server 2012 R2
As it may be late
but you can add below line in html:-
<input onkeyup="submitForm(event)" oninput="addTextName(this)" type="text" id="name-val">
and add this on js file
function submitForm(e) {
var keyCode = e.keyCode ? e.keyCode : e.which;
if (keyCode == 13){
toggleNextScreen();
}
}
keycode 13 means enter
In HTML codes:
<form action="POST" onsubmit="ajax_submit();return false;">
<b>First Name:</b> <input type="text" name="firstname" id="firstname">
<br>
<b>Last Name:</b> <input type="text" name="lastname" id="lastname">
<br>
<input type="submit" name="send" onclick="ajax_submit();">
</form>
In Js codes:
function ajax_submit()
{
$.ajax({
url: "submit.php",
type: "POST",
data: {
firstname: $("#firstname").val(),
lastname: $("#lastname").val()
},
dataType: "JSON",
success: function (jsonStr) {
// another codes when result is success
}
});
}
$('form#login').keypress(function (e) {
var keyCode = e.keyCode ? e.keyCode : e.which;
if (keyCode == 13)
{
e.preventDefault();
$('form#login').submit();
return false;
}
});
Try this:
var form = document.formname;
if($(form).length > 0)
{
$(form).keypress(function (e){
code = e.keyCode ? e.keyCode : e.which;
if(code.toString() == 13)
{
formsubmit();
}
})
}
