A client asked me to block the ENTER key in a form I created for him. After some research, here is the piece of code you have to enter into the page, which will block the event:

<script type=”text/javascript”>

$(document).ready(function() {

document.onkeypress = stopRKey;

});

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;}

}

</script>
