submitting form on enter - javascript

I'm having issue submitting search form on hitting enter as well as button click. The click works fine. Text is cleared, the /search page renders and search index shown. When I hit enter, the search text clears, but nothing else. I've added a functions handleSubmit, but it does't work. How do I make it search on enter?
handleSubmit(e) {
e.preventDefault(e);
document.getElementById("search-input")
.addEventListener("keydown", function (event) {
// event.persist();
if (event.keyCode === 13) {
document.getElementById("search-button").click();
}
});
this.setState( {
searchItem: "",
})
};
render() {
return (
<div id="search-form">
<form>
<input
type="text"
id="search-input"
placeholder="Search videos"
value={this.state.searchItem}
onChange={this.update()}
/>
<button type="submit" id="search-button" onClick={this.handleSubmit}>
<Link to={`/search?search=${this.state.searchItem}`}><img id="search-icon" src="https://image.flaticon.com/icons/svg/49/49116.svg" alt="" /></Link>
</button>
</form>
</div>
);
}

document.getElementById("id_of_your_textbox").addEventListener("keydown", function(e) {
// Prevent a blank line.
e.preventDefault();
// Enter is pressed.
if (e.keyCode == 13) {
this.submit();
}
}, false);
Simply, edit document.getElementById("search-button").click(); to document.getElementById("search-button").submit();

In forms, enter to submit is enabled by default, but you need to tell the form what to do on submit. So, add an onsubmit event to your form:
<form onSubmit={this.handleSubmit}>
...
</form>
Or, via JS's addEventListener:
form.addEventListener('submit', this.handleSubmit);
Edit: Oh, and you should add preventDefault() at the beginning of the event handler's function, something like:
handleSubmit(e) {
e.preventDefault(); //prevents the form from submitting before the end of this function
//do something here...
}

Your EventListener cant be inside the handleSubmit function.
form.addEventListener('submit', handleSubmit());

How to use jQuery function with click OR press enter with PHP

I have two different text boxes (coming from loop). Right now data is submitting with "click" event. But now I want to "Post" data after "enter" button also (for example facebook comments). How can I do this?
Here is my code
foreach ...
{
<!-- First text box -->
<input type="text" placeholder="Post your comment here" id="txt'.$FeedId.'" class="feed_in_input" name="">
<img class="feed_reply_smiley2" data-coin='.$CoinId.' data-max2='.$postID.' data-min2='.$postID.' data-stat='.$PostStatus.' id="button'.$FeedId.'" src="'.base_url().'/assets/social/images/feed_reply_smiley.svg" alt="img">
<!-- Second text box -->
<input type="text" placeholder="Reply to '.$UserName.'" id="txt'.$FeedId.'" class="feed_in_input" name="">
<img class="feed_reply_smiley" id="button'.$FeedId.'" src="'.base_url().'/assets/social/images/feed_reply_smiley.svg" alt="img">
}
Here is my script
$('.feed_reply_smiley2').unbind().click(function(e) {
//our code here
});
$('.feed_reply_smiley').unbind().click(function(e) {
//our code here
});
I just want whenever user press "enter" button to any text box then function should execute same as working on "click" event. How can I do this?
Add everything inside a form tag, after which you can detect form submit
<script>
function myfunction(e) {
e.preventDefault();
alert("yes");
}
</script>
<form method="post" onsubmit="myfunction(event)">
<input name="something" />
<input type="submit" />
</form>
The preventDefault will prevent the default behaviour of submitting data
Here's an example of how to handle enter in a text input. In your case:
$('.feed_in_input').on('keyup', function(event) {
if (event.keyCode == 13) {
// 13 = Enter Key
alert('enter key pressed.');
}
});
Next, if your goal is to fire the same code from several different events,
the first step is to set up that code as a callable function. For example:
function handleClickAndEnter() {
// our code here
alert('Action happened!');
}
Now you can call that function from each of your handlers, for example:
$('.feed_reply_smiley').on('click', handleClickAndEnter);
$('.feed_reply_smiley2').on('click', handleClickAndEnter);
$('.feed_in_input').on('keyup', function(event) {
if (event.keyCode == 13) {
// 13 = Enter Key
handleClickAndEnter();
}
});
You could also combine the first 2 handlers into one if you want:
$('.feed_reply_smiley, .feed_reply_smiley2').on('click', handleClickAndEnter);
If your code needs to determine which event was triggered, you need to go a bit further. Click "Run Code Snippet" to see this all working.
$('.feed_in_input').on('keyup', function(event) {
if (event.keyCode == 13) {
// Pass the event along to the handler
handleClickAndEnter(event);
}
});
$('.feed_reply_smiley, .feed_reply_smiley2').on('click', function(event) {
// Pass the event along to the handler
handleClickAndEnter(event)
});
// Now accept the event as a parameter
function handleClickAndEnter(event) {
// our code here
if (event.target.nodeName == "INPUT") {
alert('Someone hit enter!');
} else if (event.target.nodeName == "IMG") {
alert('Someone clicked an image!');
}
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
Input 1: <input class="feed_in_input" type="text">
<br><img src="https://via.placeholder.com/350x65" class="feed_reply_smiley">
<br><br>Input 2:<input class="feed_in_input" type="text">
<br><img src="https://via.placeholder.com/350x65" class="feed_reply_smiley2">

.keydown() when press return key

I'm trying to get the option that when a user presses the Return key, the search button is triggered.
Currently it can only be pressed on the search button, but sometimes users have the tendency to press the return key after the search entry.
$(document).ready(function() {
$('#search-button').keydown(function(event){
if (event.keyCode==13) {
Trackster.searchTracksByTitle($("#search-input").val());
}
});
$("#search-button").click(function(){
Trackster.searchTracksByTitle($("#search-input").val());
});
});
does anyone know what i did wrong here? i still cant use press return to trigger the search.
If you have a search input and a search button, an ideal practice is to get them wrapped by a form tag.
<form id="search-form">
<input type="text" id="search-input" ...>
<button type="submit" id="search-button" ...>Search</button>
</form>
Notice that the type is set to submit. It makes the button act as a submit button for the form. Now you will have to listen to the submit event of the form. The return key binding comes for free. Plus, you don't have to listen to the keydown and click events separately.
$(document).ready(function() {
$('#search-form').submit(function(event) {
event.preventDefault();
Trackster.searchTracksByTitle($("#search-input").val());
})
});
You will see that the search works when:
User types something in textbox and hits the return key
User types something in textbox and clicks on the submit button
I believe this solves your issue.
You have attached the keydown event on the search-button but in my opinion it has be attached on the search-input
$(document).ready(function() {
$('#search-input').keydown(function(event) {
if (event.keyCode === 13) {
Trackster.searchTracksByTitle($(this).val());
}
});
$("#search-button").click(function() {
Trackster.searchTracksByTitle($("#search-input").val());
});
});
This should work:
$(document).ready(function() {
var $btn = $('#search-button');
var $inElement = $btn.prev('input');
$inElement.keydown(function(event){
if (event.keyCode==13) {
Trackster.searchTracksByTitle($("#search-input").val());
}
});
$btn.click(function(){
Trackster.searchTracksByTitle($("#search-input").val());
});
});

jQuery keyboard event fires on wrong input fields

I'm creating simple forms without direct submitting, than running script before. So classic hitting enter will not send the form. However, since users are often hitting enter button to send a form, I create simple extension for hitting enter that is calling script when button is clicked.
For example, I have a simple form:
<form id="testForm">
<input type="email" id="email" />
<input type="password" id="pass" />
<button id="btnLogin" type="button">Login</button>
</form>
And extension I created is looking like this:
(function($){
$.fn.noEnter=function(options){
let settings=$.extend({btn:""},options);
function _init(){
$(this).on("keypress",function(event){
if(event.keyCode === 13) {
event.preventDefault();
$("#"+settings.btn).click();
return false;
}
});
}
this.each(function(){_init();});
return{}
};
}(jQuery));
Then in script I call something like this:
$("#email").noEnter({btn:"btnLogin"});
$("#pass").noEnter({btn:"btnLogin"});
$("#btnLogin").click(function(){
.....
});
And this is working. Problem is that it is working twice, for each input field. Looks like other input field is accepting keypress (or keydown) event. Or am I missing something?
The problem is this is referring window object in _init function to avoid that try below code
(function($){
$.fn.noEnter=function(options){
let settings=$.extend({btn:""},options);
var self = this;
function _init(){
$(self).on("keypress",function(event){
if(event.keyCode === 13) {
event.preventDefault();
$("#"+settings.btn).click();
return false;
}
});
}
this.each(function(){_init();});
return{}
};
}(jQuery));
$("#email").noEnter({btn:"btnLogin"});
$("#pass").noEnter({btn:"btnLogin"});
$("#btnLogin").click(function(e){
console.log('righty');
});
There is working example is jsfiddle if you want to try
use event.stopPropagation(); to prevent executing further.
$(this).on("keypress",function(event){
if(event.keyCode === 13) {
event.stopPropagation();
event.preventDefault();
$("#"+settings.btn).click();
return false;
}
});

Unwanted form submit using jquery event [duplicate]

I have a survey on a website, and there seems to be some issues with the users hitting enter (I don't know why) and accidentally submitting the survey (form) without clicking the submit button. Is there a way to prevent this?
I'm using HTML, PHP 5.2.9, and jQuery on the survey.
You can use a method such as
$(document).ready(function() {
$(window).keydown(function(event){
if(event.keyCode == 13) {
event.preventDefault();
return false;
}
});
});
In reading the comments on the original post, to make it more usable and allow people to press Enter if they have completed all the fields:
function validationFunction() {
$('input').each(function() {
...
}
if(good) {
return true;
}
return false;
}
$(document).ready(function() {
$(window).keydown(function(event){
if( (event.keyCode == 13) && (validationFunction() == false) ) {
event.preventDefault();
return false;
}
});
});
Disallow enter key anywhere
If you don't have a <textarea> in your form, then just add the following to your <form>:
<form ... onkeydown="return event.key != 'Enter';">
Or with jQuery:
$(document).on("keydown", "form", function(event) {
return event.key != "Enter";
});
This will cause that every key press inside the form will be checked on the key. If it is not Enter, then it will return true and anything continue as usual. If it is Enter, then it will return false and anything will stop immediately, so the form won't be submitted.
The keydown event is preferred over keyup as the keyup is too late to block form submit. Historically there was also the keypress, but this is deprecated, as is the KeyboardEvent.keyCode. You should use KeyboardEvent.key instead which returns the name of the key being pressed. When Enter is checked, then this would check 13 (normal enter) as well as 108 (numpad enter).
Note that $(window) as suggested in some other answers instead of $(document) doesn't work for keydown/keyup in IE<=8, so that's not a good choice if you're like to cover those poor users as well.
Allow enter key on textareas only
If you have a <textarea> in your form (which of course should accept the Enter key), then add the keydown handler to every individual input element which isn't a <textarea>.
<input ... onkeydown="return event.key != 'Enter';">
<select ... onkeydown="return event.key != 'Enter';">
...
To reduce boilerplate, this is better to be done with jQuery:
$(document).on("keydown", ":input:not(textarea)", function(event) {
return event.key != "Enter";
});
If you have other event handler functions attached on those input elements, which you'd also like to invoke on enter key for some reason, then only prevent event's default behavior instead of returning false, so it can properly propagate to other handlers.
$(document).on("keydown", ":input:not(textarea)", function(event) {
if (event.key == "Enter") {
event.preventDefault();
}
});
Allow enter key on textareas and submit buttons only
If you'd like to allow enter key on submit buttons <input|button type="submit"> too, then you can always refine the selector as below.
$(document).on("keydown", ":input:not(textarea):not(:submit)", function(event) {
// ...
});
Note that input[type=text] as suggested in some other answers doesn't cover those HTML5 non-text inputs, so that's not a good selector.
Section 4.10.22.2 Implicit submission of the W3C HTML5 spec says:
A form element's default button is the first submit button in tree order whose form owner is that form element.
If the user agent supports letting the user submit a form implicitly (for example, on some platforms hitting the "enter" key while a text field is focused implicitly submits the form), then doing so for a form whose default button has a defined activation behavior must cause the user agent to run synthetic click activation steps on that default button.
Note: Consequently, if the default button is disabled, the form is not submitted when such an implicit submission mechanism is used. (A button has no activation behavior when disabled.)
Therefore, a standards-compliant way to disable any implicit submission of the form is to place a disabled submit button as the first submit button in the form:
<form action="...">
<!-- Prevent implicit submission of the form -->
<button type="submit" disabled style="display: none" aria-hidden="true"></button>
<!-- ... -->
<button type="submit">Submit</button>
</form>
One nice feature of this approach is that it works without JavaScript; whether or not JavaScript is enabled, a standards-conforming web browser is required to prevent implicit form submission.
If you use a script to do the actual submit, then you can add "return false" line to the onsubmit handler like this:
<form onsubmit="return false;">
Calling submit() on the form from JavaScript will not trigger the event.
I had to catch all three events related to pressing keys in order to prevent the form from being submitted:
var preventSubmit = function(event) {
if(event.keyCode == 13) {
console.log("caught ya!");
event.preventDefault();
//event.stopPropagation();
return false;
}
}
$("#search").keypress(preventSubmit);
$("#search").keydown(preventSubmit);
$("#search").keyup(preventSubmit);
You can combine all the above into a nice compact version:
$('#search').bind('keypress keydown keyup', function(e){
if(e.keyCode == 13) { e.preventDefault(); }
});
Use:
$(document).on('keyup keypress', 'form input[type="text"]', function(e) {
if(e.keyCode == 13) {
e.preventDefault();
return false;
}
});
This solution works on all forms on a website (also on forms inserted with Ajax), preventing only Enters in input texts. Place it in a document ready function, and forget this problem for a life.
Instead of preventing users from pressing Enter, which may seem unnatural, you can leave the form as is and add some extra client-side validation: When the survey is not finished the result is not sent to the server and the user gets a nice message telling what needs to be finished to complete the form. If you are using jQuery, try the Validation plugin:
http://docs.jquery.com/Plugins/Validation
This will require more work than catching the Enter button, but surely it will provide a richer user experience.
I can't comment yet, so I'll post a new answer
Accepted answer is ok-ish, but it wasn't stopping submit on numpad enter. At least in current version of Chrome. I had to alter the keycode condition to this, then it works.
if(event.keyCode == 13 || event.keyCode == 169) {...}
A nice simple little jQuery solution:
$("form").bind("keypress", function (e) {
if (e.keyCode == 13) {
return false;
}
});
A completely different approach:
The first <button type="submit"> in the form will be activated on pressing Enter.
This is true even if the button is hidden with style="display:none;
The script for that button can return false, which aborts the submission process.
You can still have another <button type=submit> to submit the form. Just return true to cascade the submission.
Pressing Enter while the real submit button is focussed will activate the real submit button.
Pressing Enter inside <textarea> or other form controls will behave as normal.
Pressing Enter inside <input> form controls will trigger the first <button type=submit>, which returns false, and thus nothing happens.
Thus:
<form action="...">
<!-- insert this next line immediately after the <form> opening tag -->
<button type=submit onclick="return false;" style="display:none;"></button>
<!-- everything else follows as normal -->
<!-- ... -->
<button type=submit>Submit</button>
</form>
It is my solution to reach the goal,
it is clean and effective.
$('form').submit(function () {
if ($(document.activeElement).attr('type') == 'submit')
return true;
else return false;
});
You can also use javascript:void(0) to prevent form submission.
<form action="javascript:void(0)" method="post">
<label for="">Search</label>
<input type="text">
<button type="sybmit">Submit</button>
</form>
<form action="javascript:void(0)" method="post">
<label for="">Search</label>
<input type="text">
<button type="sybmit">Submit</button>
</form>
Not putting a submit button could do. Just put a script to the input (type=button) or add eventListener if you want it to submit the data in the form.
Rather use this
<input type="button" onclick="event.preventDefault();this.closest('form').submit();">
than using this
<input type="submit">
Note: onclick is needed here to actually submit the form when clicked. By default, type="button" is not sufficient enough to submit.
Giving the form an action of 'javascript:void(0);' seems to do the trick
<form action="javascript:void(0);">
<input type="text" />
</form>
<script>
$(document).ready(function() {
$(window).keydown(function(event){
if(event.keyCode == 13) {
alert('Hello');
}
});
});
</script>
Do not use type="submit" for inputs or buttons.
Use type="button" and use js [Jquery/angular/etc] to submit form to server.
This is the perfect way, You will not be redirected from your page
$('form input').keydown(function (e) {
if (e.keyCode == 13) {
e.preventDefault();
return false;
}
});
I needed to prevent only specific inputs from submitting, so I used a class selector, to let this be a "global" feature wherever I need it.
<input id="txtEmail" name="txtEmail" class="idNoEnter" .... />
And this jQuery code:
$('.idNoEnter').keydown(function (e) {
if (e.keyCode == 13) {
e.preventDefault();
}
});
Alternatively, if keydown is insufficient:
$('.idNoEnter').on('keypress keydown keyup', function (e) {
if (e.keyCode == 13) {
e.preventDefault();
}
});
Some notes:
Modifying various good answers here, the Enter key seems to work for keydown on all the browsers. For the alternative, I updated bind() to the on() method.
I'm a big fan of class selectors, weighing all the pros and cons and performance discussions. My naming convention is 'idSomething' to indicate jQuery is using it as an id, to separate it from CSS styling.
You could make a JavaScript method to check to see if the Enter key was hit, and if it is, to stop the submit.
<script type="text/javascript">
function noenter() {
return !(window.event && window.event.keyCode == 13); }
</script>
Just call that on the submit method.
There are many good answers here already, I just want to contribute something from a UX perspective. Keyboard controls in forms are very important.
The question is how to disable from submission on keypress Enter. Not how to ignore Enter in an entire application. So consider attaching the handler to a form element, not the window.
Disabling Enter for form submission should still allow the following:
Form submission via Enter when submit button is focused.
Form submission when all fields are populated.
Interaction with non-submit buttons via Enter.
This is just boilerplate but it follows all three conditions.
$('form').on('keypress', function(e) {
// Register keypress on buttons.
$attr = $(e.target).attr('type');
$node = e.target.nodeName.toLowerCase();
if ($attr === 'button' || $attr === 'submit' || $node === 'textarea') {
return true;
}
// Ignore keypress if all fields are not populated.
if (e.which === 13 && !fieldsArePopulated(this)) {
return false;
}
});
ONLY BLOCK SUBMIT but not other, important functionality of enter key, such as creating a new paragraph in a <textarea>:
window.addEventListener('keydown', function(event) {
//set default value for variable that will hold the status of keypress
pressedEnter = false;
//if user pressed enter, set the variable to true
if (event.keyCode == 13)
pressedEnter = true;
//we want forms to disable submit for a tenth of a second only
setTimeout(function() {
pressedEnter = false;
}, 100)
})
//find all forms
var forms = document.getElementsByTagName('form')
//loop through forms
for (i = 0; i < forms.length; i++) {
//listen to submit event
forms[i].addEventListener('submit', function(e) {
//if user just pressed enter, stop the submit event
if (pressedEnter == true) {
updateLog('Form prevented from submit.')
e.preventDefault();
return false;
}
updateLog('Form submitted.')
})
}
var log = document.getElementById('log')
updateLog = function(msg) {
log.innerText = msg
}
input,
textarea {
display: inline-block;
margin-bottom: 1em;
border: 1px solid #6f6f6f;
padding: 5px;
border-radius: 2px;
width: 90%;
font-size: 14px;
}
input[type=submit] {
background: lightblue;
color: #fff;
}
<form>
<p>Sample textarea (try enter key):</p>
<textarea rows="4">Hit enter, a new line will be added. But the form won't submit</textarea><br/>
<p>Sample textfield (try enter key):</p>
<input type="text" placeholder="" />
<br/>
<input type="submit" value="Save" />
<h3 id="log"></h3>
</form>
If you're using Alpine, you can use the following to prevent form submission by pressing Enter:
<div x-data>
<form x-on:keydown.prevent.enter="">...</form>
</div>
Alternatively you can use the .window modifier to register the event listener on the root window object on the page instead of the element.
<form>
<div x-data>
<input x-on:keydown.window.prevent.enter="" type="text">
</div>
</form>
I have use this Code to disable 'ENTER' key press on both input type [text] and input type [password], you can add other too like input type [email] or also can apply on your desired Input type.
$(document).on('keyup keypress', 'form input[type="text"] , input[type="password"]', function(e) {
if (e.keyCode == 13) {
e.preventDefault();
return false;
}
});
$(document).on("keydown","form", function(event)
{
node = event.target.nodeName.toLowerCase();
type = $(event.target).prop('type').toLowerCase();
if(node!='textarea' && type!='submit' && (event.keyCode == 13 || event.keyCode == 169))
{
event.preventDefault();
return false;
}
});
It works perfectly!
If using Vue, use the following code to prevent users from submitting the form by hitting Enter:
<form #submit.prevent>...</form>
I had a similiar problem, where I had a grid with "ajax textfields" (Yii CGridView) and just one submit button. Everytime I did a search on a textfield and hit enter the form submitted. I had to do something with the button because it was the only common button between the views (MVC pattern). All I had to do was remove type="submit" and put onclick="document.forms[0].submit()
I think it's well covered with all the answers, but if you are using a button with some JavaScript validation code you could just set the form's onkeypress for Enter to call your submit as expected:
<form method="POST" action="..." onkeypress="if(event.keyCode == 13) mySubmitFunction(this); return false;">
The onkeypress JS could be whatever you need to do. There's no need for a larger, global change. This is especially true if you're not the one coding the app from scratch, and you've been brought into fix someone else's web site without tearing it apart and re-testing it.
Something I have not seen answered here: when you tab through the elements on the page, pressing Enter when you get to the submit button will trigger the onsubmit handler on the form, but it will record the event as a MouseEvent. Here is my short solution to cover most bases:
This is not a jQuery-related answer
HTML
<form onsubmit="return false;" method=post>
<input type="text" /><br />
<input type="button" onclick="this.form.submit()" value="submit via mouse or keyboard" />
<input type="button" onclick="submitMouseOnly(event)" value="submit via mouse only" />
</form>
JavaScript
window.submitMouseOnly=function(evt){
let allow=(evt instanceof MouseEvent) && evt.x>0 && evt.y>0 && evt.screenX > 0 && evt.screenY > 0;
if(allow)(evt.tagName=='FORM'?evt.target:evt.target.form).submit();
}
To find a working example: https://jsfiddle.net/nemesarial/6rhogva2/
Using Javascript (without checking any input field):
<script>
window.addEventListener('keydown', function(e) {
if (e.keyIdentifier == 'U+000A' || e.keyIdentifier == 'Enter' || e.keyCode == 13) {
e.preventDefault();
return false;
}
}, true);
</script>
If someone wants to apply this on specific fields, for example input type text:
<script>
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 works well in my case.
Go into your css and add that to it then will automatically block the submission of your formular as long as you have submit input if you no longer want it you can delete it or type activate and deactivate instead
input:disabled {
background: gainsboro;
}
input[value]:disabled {
color: whitesmoke;
}
This disables enter key for all the forms on the page and does not prevent enter in textarea.
// disable form submit with enter
$('form input:not([type="submit"])').keydown((e) => {
if (e.keyCode === 13) {
e.preventDefault();
return false;
}
return true;
});

Getting How a Form Was Submitted on submit event

I have a form that has a couple of buttons on it. Two of the buttons use ajax to submit the form and clear it so that the user can add multiple records before moving on. The last button is for when the user is done with the page and wants to move onto the next page. Is it possible in jQuery's .submit() method to tell how the form was submitted (hitting enter, or get the object of the button clicked)?
Not sure if it is best practices, but I found that if I create a submit event handler and then after that create the handlers for the other buttons it seems to work okay, at least in Chrome.
Here's an example
$(function(){
$('form#frmField').submit(function(evt){
alert('Form Submitted');
return false;
});
$('input#btnReset').click(function(){
alert('Form Reset');
return false;
});
});
You can define onclick event handlers for your buttons which would save the state into some global-scope variable. Then you would check the state of the variable at onsubmit handler.
http://jsfiddle.net/archatas/6dsFc/
you can try this way:
HTML:
<form id="myform">
<input type="text" id="text1" name="text1" /><br />

JS:
$('#myform').bind('submit', function(event, from) {
if(from)
$('#data').append("from :" + $(from).attr('id') + '<br />');
return false;
});
$('#myform').keypress(function(event) {
if (event.which == '13') {
event.preventDefault(); //preventDefault doesn't stop further propagation of the event through the DOM. event.stopPropagation should be used for that.
event.stopPropagation();
$(this).trigger('submit', [this]);
return false;
}
});
$('.button-submit').bind('click', function(event) {
event.stopPropagation();
$('#myform').trigger('submit', [this]);
return false;
});
example
event.preventDefault
jQuery events pass an event object through their calls. You can use this event object to determine how the event was called.
Specifically, if you pass it as a parameter e in the function, you can check e.type, which should be equal to click, or e.which, which if it was submitted with an enter, would be 13.
You can use target to find out which DOM element initiated the submission with e.target.
So,
jQuery('#foo').click(function(e){
var initiator = $(e.target); //jQuery object for the DOM element that initiated the submit
if(e.type==="click")
{
//is a click
}
else if(e.which==="13")
{
//is an 'enter' triggered submission
}
});
});
