To
restrict user to enter only numbers in textbox we need to write the following
code
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>jQuery allow only numbers or numeric characters in textbox</title>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.8.2.js"></script>
<script type="text/javascript">
$(function()
{
$('#txtNumeric').keydown(function(e) {
if (e.shiftKey || e.ctrlKey || e.altKey) {
e.preventDefault();
} else {
var key = e.keyCode;
if (!((key == 8) || (key == 46) || (key >= 35 &&
key <= 40) || (key >= 48 && key <= 57) || (key >= 96
&& key <= 105))) {
e.preventDefault();
}
}
})
})
</script>
</head>
<body>
<form id="form1"
runat="server">
<div>
<asp:TextBox ID="txtNumeric"
runat="server"/>
