Click me Only Once - jQuery

I have seen a very frequently asked question by developers – How to execute an event only once. With jQuery, achieving this requirement is very simple using One

Here’s how:

<html xmlns="http://www.w3.org/1999/xhtml">
<
head>
<
title>Click me once only</title>
<
script type="text/javascript"
src="http://ajax.microsoft.com/ajax/jQuery/jquery-1.4.2.min.js">
</
script>
<
script type="text/javascript">
$(function() {
$("#Submit1").one('click', function() {
$(this).val("No more alerts");
alert('');
});
});
</script>
</
head>
<
body>
<
input id="Submit1" type="submit" value="submit" />
</
body>
</
html>


In the code shown above, the click event is fired only once and the alert is displayed. All subsequent clicks will do nothing
