There are times that you do not want a form to automatically submit when a user hits the enter key. Or if you want to do some validation via javascript before you allow the submit to go through.
//Bind this keypress function to all of the input tags
$("input").keypress(function (evt) {
//Deterime where our character code is coming from within the event
var charCode = evt.charCode || evt.keyCode;
if (charCode == 13) { //Enter key's keycode
return false;
}
});
By returning false in the keypress function it tells the browser not to allow the enter key event.
