I'm trying get my <a> tag triggered when the user press on the "enter" key. (onkeypress).
my <a> tag:
<a href="javascript:search()" onkeypress="return runScript(event)">
this is my javascript :
function runScript(e)
{
if (e.keyCode == 13) {
alert("dssd");
return false;
}
}
I dont know whats messed up ?
its work for me
Open in new window using javascript
javaScript
window.runScript = function (e) {
if (e.keyCode == 13) {
alert('ss');
return false;
}
else {
return true;
}
}
window.search = function () {
alert('s');
}

Write your html as given below. Note the property tabindex which makes the a tag focusable in certain browsers.
<a id="link" href="http://google.com" onkeydown="runScript(event)" tabindex="1">I am a link</a>
If you need an autofocus on load, you can use the jQuery function focus as shown below.
$(document).ready(
function(e){
$("#link").focus();
}
);
Then your function
function runScript(e){
if(e.keyCode == 13){
alert("pressed enter key");
}
}
you have to call e.preventDefault(); (or return false in some browsers) if you want to prevent the link load the link in href.
function runScript(e){
e.preventDefault();
if(e.keyCode == 13){
alert("pressed enter key");
}
return false;
}
see a demo here:
http://jsfiddle.net/diode/hfJSn/9/show press enter key when the page is loaded
The ENTER key actually triggers the onclick event:
<a href="#" onclick="alert('hello!');">
This means that your search() function inside the href will execute before the onkeypress event.
That works in my browser, though I suspect it's not the way to achieve what you actually want to do... (maybe?)
Number one, you probably don't want it to "return" anything, so you can just do onkeypress="runScript(e)" and it'll run. If that function does return a value, it's not gonna go anywhere...
Number two, it's kinda rare that a keydown event would fire on an anchor (<a>) element, unless of course the user tabs through the other elements 'till it has focus and then presses a key (usually the browser will "highlight" the element that currently has keyboard focus, if it's not just the whole page). Are you wanting your script to run when someone presses enter after typing in a search box or something? if so, you probably want to listen for the event on the search box itself, so add it as that element's onkeydown attribute (for example: <input id="mySearchBox" onkeydown="runScript(e)">) if you just want it to run whenever the user presses enter, regardless of focus or typing text into any particular field, just do as edmastermind29's comment said and add the event listener to the whole document.
Have you tried adding this to your script?
document.onkeypress = runScript;

I currently have a button with an onclick attribute, directing to a JS function.
After I click it with my mouse, pressing the Enter key clicks the button as well, which I want to disable.
My button:
<button onclick = "action()">Button</button>
My JS function:
function action(){
//do something
}
I tried solutions from Disable Enter Key and Disabling enter key for form, but they don't work.
How do I solve this? Should I not use onclick? I would like a solution in pure JS.
You could have an event listener listening for a keydown event and check if it's the enter key and the target your button. In that case disable the event.
Something like this should work, you can add the correct type:
window.addEventListener('keydown',(e) => {
if (e.keyIdentifier =='U+000A' || e.keyIdentifier =='Enter' || e.keyCode == 13)
if (e.target.nodeName=='BUTTON' && e.target.type=='') {
e.preventDefault()
e.stopPropagation()
return false
}
}, true);
try setting the button to .blur() or set focus to another element
<button onclick = "action();">Click this</button>
function action(){
//do something
this.blur()
}
I have been searching and have not found any particular thread that addresses my issue.
I am trying to either write an event listener or a conditional action with JavaScript that reacts when a user selects the TAB key and shifts focus to the appropriate element on screen.
Current DIV id has focus on screen => id="Slide14549accStr2"
When the user selects the TAB key, I want the user's focus to immediately shift to DIV id "Titleinformation_tb". I am unable to change the TabIndex in the HTML to do this the normal way, so I am left with using javascript in some form.
Here is what I have so far.
document.getElementById('Slide14549accStr2').addEventListener('keydown') {
if event.keyCode == 9) {
var elem =
document.getElementById('Titleinformation_tb');
$(elem).focus();
};
I would appreciate any help and feedback.
If you just fix all the syntax errors, it works just fine, but you should be preventing the default action as well, to make sure it doesn't tab to the next element
document.getElementById('Slide14549accStr2').addEventListener('keydown', function(event) {
if (event.keyCode == 9) {
event.preventDefault();
var elem = document.getElementById('Titleinformation_tb');
elem.focus();
}
});
<input id="Slide14549accStr2" placeholder="Focus this, and tab out">
<br><br><br>
<input><input><input>
<br><br><br>
<input id="Titleinformation_tb" placeholder="Should go here">
You were missing the function call.
document.getElementById('Slide14549accStr2')
.addEventListener('keydown',function(e){
if (event.keyCode == 9){
var elem = document.getElementById('Titleinformation_tb');
$(elem).focus();
}
});
I want to detect the ENTER keypress of the Address Bar and also, the "Go(to the specified URL)" button using Javascript.
As per my previous efforts using "keycode==13" did not work as required.
say, in the following code:
window.onkeypress = testKeyEvent;
function testKeyEvent(e) {
if (e.keyCode == 13) //We are using Enter key press event for test purpose.
{
alert('Enter key pressed');
}
else //If any other button pressed.
{
alert('Not Enter key pressed');
}
} </script>
I want first the Alert box to be displayed,after I have typed any URL(valid or not) in the address box and Pressed ENTER/ Clicked GO button and then go to specified URL.
Is it Possible? I know I am missing out on a lot of things, Please mention about them.
If I am interpreting your question correctly, I don't think you can do this, because the context in which the JavaScript runs stops at the Document (meaning, JavaScript doesn't even quite know that the browser itself exists).
You can't detect the keystroke because it's outside your window, but you can detect navigation away from your page like
window.onbeforeunload = function () {
alert("Leaving page...");
}
I would like to trigger a click if enter is pressed inside an input tag, but would like to have the default event strategy in all other cases. I have tried it this way:
$("#keywords").keypress(function(e) {
if (e.charCode === 13) {
$("#campus-search").click();
} else {
$("#keywords").val($("#keywords").val() + String.fromCharCode(e.charCode));
}
});
It works, but I am still not satisfied, because when I click inside the input somewhere in the middle of text or press the left button, or home button and then try to type some text, it will show it at the end of the input, which is bad user-experience. Can I keep the input to work in the default way except the case when enter is pressed?
I think what you are looking for is this:
$(document).ready(function () {
$("#test").keyup(function (event) {
if (event.keyCode == 13) {
$("#campus-search").click();
}
});
$("#campus-search").click(function () {
console.log("BUTTON IS CLICKED");
});
});
The input will act completely normal and everything works on default, unless when you press the enter button (keyCode = 13), then the button .click() event will be triggered.

# Update: Just one hint for the code in your question, do not use charCode, as it is deprecated.
This feature has been removed from the Web. Though some browsers may still support it, it is in the process of being dropped. Do not use it in old or new projects. Pages or Web apps using it may break at any time.
(E.g. charCode does not work with FF v29.0.1)
And something different but important to know:
charCode is never set in the keydown and keyup events. In these cases, keyCode is set instead.
Source: https://developer.mozilla.org/en-US/docs/Web/API/event.charCode
This should work
$("#keywords").keypress(function(e) {
if (e.charCode === 13) {
e.preventDefault(); // prevent default action of the event if the event is keypress of enter key
$("#campus-search").click();
} else {
$("#keywords").val($("#keywords").val() + String.fromCharCode(e.charCode));
}
});
I think you can eliminate the else clause entirely to get your desired result.
Look at this jsfiddle.
The keypress function does not capture non-printing keys, such as shift, esc, delete, and enter, so the best way to go about this would be have two event handlers: one for keypress, as you have defined above, and one for keydown that checks for the charCode 13 and then performs the click() event on $(#campus-search) if that keycode is passed (by an enter press).
Demo
This is what you are looking for:
HTML:
<input id="keywords" type="text" value="" />
<input id="campus-search" type="button" value="Campus Search" />
JavaScript / jQuery:
$("#keywords").keypress(function (e) {
if (e.charCode === 13) {
$("#campus-search").click();
} else {
$("#keywords").val($("#keywords").val() + String.fromCharCode(e.charCode));
}
});
$("#campus-search").on("click", function () {
alert("Searching..");
});

I have a HTML form on my page. When i am putting some value in one of the text fields in form and press 'Enter key' the form gets submitted instantly. I think this is happening due to default focus is on submit button. But i try to remove that focus using blur() function, it is not working. I am using Chrome.
Is there any way to avoid this scenario?
All suggestions are welcome. thanks in advance.
The Submit button is not actually focused; Enter in a text field is supposed to submit the form.
You could register a handler for the submit event, and then only allow it if the Submit button was actually focused at the time submit was requested.
However, you'll be deliberately breaking the way that HTML forms work. Not everyone wants to submit the form using the One True Way of actually clicking the Submit button (also, you'll be breaking accessibility and may introduce browser-specific bugs).
No. The focus is still on the text field. Pressing enter there is supposed to submit the form (and bypasses the submit button entirely).
You can suppress the behavior using JavaScript, but since it is normal behavior for the browser, I wouldn't recommend doing so.
try this solution: replace the 'input' with 'button' and add attribute
type equals 'button' and handle the onclick event with submit javascript function
<form name='testForm'>
<input type='text' value="myName" />
<button type='button' onclick='testForm.submit()'/>
</form>
i think it works also with tag input adding the same attribute

blur() is the way to go. It works like this:
<button onclick="this.blur();">some button</button>
Note that you should not use JavaScript and DOM-events using Attributes. This is just for demonstration purposes. Try to be unobstrusive.
Maybe it will help you out, the form is "supposed" to be sent with enter in the text box (HTML by design), it is no a matter of focus.
If you want to avoid it, check this out.
This is the proposed script:
function disableEnterKey(e)
{
var key;
if(window.event)
key = window.event.keyCode; //IE
else
key = e.which; //firefox
return (key != 13);
}
Good luck, tell me if you need any clarification!
EDIT: I do agree with Piskvor answer, it may bring some bugs
this has nothing to do with the focus, its just the default behavior of you browser. to avoid this, you could try to cath the enter-keypress like this (Source - but there are a lot of other solutions (most working the same way, just using other events like the firms onsubmit instead of the documents onkeypress)):
function catchEnter(e){
// Catch IE’s window.event if the
// ‘e’ variable is null.
// FireFox and others populate the
// e variable automagically.
if (!e) e = window.event;
// Catch the keyCode into a variable.
// IE = keyCode, DOM = which.
var code = (e.keyCode) ? e.keyCode : e.which;
// If code = 13 (enter) or 3 (return),
// cancel it out; else keep going and
// process the key.
if (code == 13 || code == 3)
return false;
else
return true;
}
// Anonymous method to push the onkeypress
// onto the document.
// You could finegrain this by
// document.formName.onkeypress or even on a control.
window.onload = function() { document.onkeypress = catchEnter; };
Change:
<input type="text" ... >
To:
<textarea ... ></textarea>
You may need to mess around with the attributes a bit, I've left them signified as ....
try to add on the keypress event of your button this javascript function :
function ButtonKeyPress()
{
var code = (window.event.which) ? window.event.which : window.event.keyCode;
if ( code == 13 )
{
event.returnValue = false;
return false;
}
return true;
}
So, you have a form. In this form, you have a text input, and a submit button.
You get in the text input, you type some text, than you press "Enter". This submits the form.
You would like to break this normal behavior.
I think this is not a good idea : The convention says that when your in a text input and press "Enter", it submits the form. If you change this behavior, users could be (I don't find the right word, let's say ~) surprised.
Anyway, if you still want to do this, you should listen for the keypress event on the text input, and than prevent default behaviour shoud do the work.
let's say you use jQuery :
$(input[type=text]).bind('keypress', function(evt) {
if(evt.keyCode == 13) {
evt.preventDefault();
}
});
This should do it. I didn't test it, maybe I made mistakes, but you got the idea, no ?
And maybe keyup is better than keypress... I don't know very well this, not enough practice on key bindings
The easiest way is to set css style like this:
&:focus {
outline: 0 none;
}
