[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();
}
}
