jQuery - keydown / keypress /keyup ENTERKEY detection?

Question

Trying to get jQuery to detect enter input, but space and other keys are detected, enter isn't detected. What's wrong below:

<script>
$("#entersomething").keyup(function(e){alert("up");
    var code = (e.keyCode ? e.keyCode : e.which);
    if(code==13)e.preventDefault();
    if(code==32||code==13||code==188||code==186){
        $("#displaysomething").html($(this).val());
    });
</script>
<input id="entersomething" />
<div id="displaysomething"></div>
​

Answer 1

JavaScript/jQuery

$("#entersomething").keyup(function(e){ 
    var code = e.which; // recommended to use e.which, it's normalized across browsers
    if(code==13)e.preventDefault();
    if(code==32||code==13||code==188||code==186){
        $("#displaysomething").html($(this).val());
    } // missing closing if brace
});

HTML

<input id="entersomething" type="text" /> <!-- put a type attribute in -->
<div id="displaysomething"></div>

jQuery Sparkle includes a custom event for this. The source can be seen here: http://github.com/balupton/jquery-sparkle/blob/master/scripts/resources/jquery.events.js

Here is a demo http://www.balupton.com/sandbox/jquery-sparkle/demo/#event-enter
