In previous articles
I explained jQuery slide div from left to right or

jQuery enable or disable controls, jQuery Ajax JSON Example in asp.net, jQuery set some time delay for function or method execution,
jQuery cascading dropdownlist example
in asp.net,
jQuery hide div after 5 seconds and many articles
relating to css, jQuery, JavaScript, Asp.net, SQL

string contains special characters in jQuery.
To check if string
contains special characters we need to write the code like as shown below
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>jQuery Check if string
contains special characters or not</title>
<script type="text/javascript"
src="http://code.jquery.com/jquery-1.10.2.js"></script>
<script type="text/javascript">
$(function () {
$('#btnClick').click(function () {
var str = $('#txtName').val();
if (/^[a-zA-Z0-9- ]*$/.test(str) == false) {
alert('Your String Contains illegal
Characters.');
}
})
})
</script>
</head>
<body>
<form id="form1">
<div>
Enter Search:<input type="text" id="txtName" />
<input type="button"
id="btnClick"
value="Check"
/>
</div>
</form>
</body>
</html>
