Detect the Enter key in a text input field
I'm trying to do a function if enter is pressed while on specific input.
What I'm I doing wrong?
$(document).keyup(function (e) {
开发者_Python百科if ($(".input1").is(":focus") && (e.keyCode == 13)) {
// Do something
}
});
Is there a better way of doing this which would say, if enter pressed on .input1
do function?
$(".input1").on('keyup', function (e) {
if (e.key === 'Enter' || e.keyCode === 13) {
// Do something
}
});
// e.key is the modern way of detecting keys
// e.keyCode is deprecated (left here for for legacy browsers support)
// keyup is not compatible with Jquery select(), Keydown is.
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("input1")[0];
node.addEventListener("keyup", function(event) {
if (event.key === "Enter") {
// Do work
}
});
Modern style, with lambda and destructuring
node.addEventListener("keyup", ({key}) => {
if (key === "Enter") {
// Do work
}
})
If you must use jQuery:
$(document).keyup(function(event) {
if ($(".input1").is(":focus") && event.key == "Enter") {
// Do work
}
});
Mozilla Docs
Supported Browsers
$(document).keyup(function (e) {
if ($(".input1:focus") && (e.keyCode === 13)) {
alert('ya!')
}
});
Or just bind to the input itself
$('.input1').keyup(function (e) {
if (e.keyCode === 13) {
alert('ya!')
}
});
To figure out which keyCode you need, use the website http://keycode.info
Try this to detect the Enter
key pressed in a textbox.
$(function(){
$(".input1").keyup(function (e) {
if (e.which == 13) {
// Enter key pressed
}
});
});
The best way I found is using keydown
( the keyup
doesn't work well for me).
Note: I also disabled the form submit because usually when you like to do some actions when pressing Enter Key the only think you do not like is to submit the form :)
$('input').keydown( function( event ) {
if ( event.which === 13 ) {
// Do something
// Disable sending the related form
event.preventDefault();
return false;
}
});
It may be too late to answer this question. But the following code simply prevents the enter key. Just copy and paste should work.
<script type="text/javascript">
function stopRKey(evt) {
var evt = (evt) ? evt : ((event) ? event : null);
var node = (evt.target) ? evt.target : ((evt.srcElement) ? evt.srcElement : null);
if ((evt.keyCode == 13) && (node.type=="text")) {return false;}
}
document.onkeypress = stopRKey;
</script>
The solution that work for me is the following
$("#element").addEventListener("keyup", function(event) {
if (event.key === "Enter") {
// do something
}
});
Try this to detect the Enter key pressed in a textbox.
$(document).on("keypress", "input", function(e){
if(e.which == 13){
alert("Enter key pressed");
}
});
DEMO
A solution that worked for me is this:
<input onkeydown="if (event.key == 'Enter'){//do logic}else{}">
$(document).ready(function () {
$(".input1").keyup(function (e) {
if (e.keyCode == 13) {
// Do something
}
});
});
This code handled every input for me in the whole site. It checks for the ENTER KEY inside an INPUT field and doesn't stop on TEXTAREA or other places.
$(document).on("keydown", "input", function(e){
if(e.which == 13){
event.preventDefault();
return false;
}
});
Here is what I did for my angular project:
HTML:
<input
class="form-control"
[(ngModel)]="searchFirstName"
(keyup)="keyUpEnter($event)"
/>
TypeScript:
keyUpEnter(event: KeyboardEvent) {
if (event.key == 'Enter') {
console.log(event);
}
}
