Now I will explain how to use JavaScript to remove special characters from textbox entered by user.
To
implement this we need to write the code like as shown below
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Remove
Special Characters from the Textbox using JavaScript</title>
<script language="javascript"
type="text/javascript">
function RemoveSpecialChar(txtName) {
if (txtName.value != ''
&& txtName.value.match(/^[\w ]+$/) == null)
{
txtName.value = txtName.value.replace(/[\W]/g,
'');
}
}
</script>
</head>
<body>
<div>
<b>Enter
Text:</b><input id="txtName" type="text" onkeyup="javascript:RemoveSpecialChar(this)" />
</div>
</body>
</html>
