Some times you want to disable the form submission when someone hits the enter key.
Here is how to do it.

// Ignores the enter key to prevent accidental form submission.
// Usage: <input class="" type="text" id="filter" name="filter" value="" onKeyPress="return my_ignore_enter(event);" />

function my_ignore_enter(e) {
var characterCode;

if (window.event) { // IE
characterCode = e.keyCode;
} else if(e.which) { // Netscape/Firefox/Opera
characterCode = e.which;
}

if (characterCode == 13) {
return false;
}

return true;
}
