<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>textbox to accept only numbers (digits)</title>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
$(document).ready(function(){
//called when key is pressed in textbox
$("#quantity").keypress(function (e)
{
//if the letter is not digit then display error and don't type anything
if( e.which!=8 && e.which!=0 && (e.which<48 || e.which>57))
{
//display error message
$("#errmsg").html("Digits Only").show().fadeOut("slow");
return false;
}
});
});
</script>
</script>
<style type="text/css">
body {
font: 12px Verdana,Arial, Helvetica, sans-serif;
margin: 10px auto;
width: 400px;
}
p { color:blue; }
#errmsg { color:red; }
