This question already has an answer here:
$(window).keydown(function(event){
if(event.keyCode == 13) {
event.preventDefault();
return false;
}
});
The above is the code I got which effectively kills the "enter" key as a form submitter throughout the system, which is exactly what I want. However, the enter key is also disabled on textarea
tags - which the users should be able to hit enter on in order to go to the next rows. So is there a way to modify the above code to detect IF the enter is coming from within a textarea
tag, it doesn't run the event.preventDefault();
line?
I have so many forms throughout the site - having to configure them individually would be a nightmare, and probably doesn't make sense - there's gotta be a universal way. The above code runs on every single page of the site to prevent accidental submits by hitting "enter".
i would prefer the keyup
event ... use the event.target
property
$(window).keydown(function(event){
if((event.which== 13) && ($(event.target)[0]!=$("textarea")[0])) {
event.preventDefault();
return false;
}
});
demo
You may try this
$(document).ready(function(){
$(window).keydown(function(event){
if(event.keyCode == 13 && event.target.nodeName!='TEXTAREA')
{
event.preventDefault();
return false;
}
});
});
A fiddle is here.
@3nigma's solution would work just fine but here another way of achieving this behavior:
$(function(){
$('#myform').find('input,select').keydown(function(event){
if ( event.keyCode == 13 ){
event.preventDefault();
}
});
});
$('#form_editar').keypress(function(e) {
var allowEnter = {"textarea": true, "div": true};
var nodeName = e.target.nodeName.toLowerCase();
if (e.keyCode == 13 && allowEnter[nodeName] !== true) {
e.preventDefault();
}
});
I edit from @The Alpha a bit, i use div for wysiwyg editors :)...
This seems like a good opportunity to use the event object and a scalpel-like approach on this mosquito instead of a cannon-like approach.
In other words, something like this:
...
// Only watch for a bad type of submission when a submission is requested.
$('form .contact-form').submit(function(e){
// If a submit is requested, and it's done via keyboard enter, stop it.
if ((e.keyCode || e.which) == 13) ? ;){ // Try to use normalized enter key code
e.preventDefault(); // Prevent the submit.
}
// All other mouse actions just go through.
});
The advantage here should be relatively obvious, if you hit enter anywhere that doesn't submit a form, this code doesn't know, doesn't care, doesn't cause problems.
I have found this works best. Especially if you want to use enter key behaviors in other elements just not to send the form back. I am just expanding on 3nigma's answer.
$("form").keypress(function (event) {
if (event.keyCode == 13 && ($(event.target)[0]!=$("textarea")[0])) {
return false;
}
});
Why not just block the form's submit
event from triggering instead?
$('form').submit(function(event){
event.preventDefault();
});
