Selecting and removing multiple classes in jQuery

If you have multiple ASP.NET Panels or <div> tags in your page with different classes, then here's how to select some classes and leave others using jQuery :


<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

<script src="Scripts/jquery-1.3.min.js" 

type="text/javascript">

</script>

<script type="text/javascript">

$(document).ready(function() {

$('.oneClass, .oneMoreClass').

removeClass('notReqClass').hover(

    function() {

        $(this).css({ background: "#C1DAD7" }); 

    },

    function() {

        $(this).css({ background: "#ffffff" }); 

     }

    ); 

});

 

</script>

 

<style type="text/css">

.oneClass

{

    font-style:italic;

}

.oneMoreClass

{

    font-weight:bold;

}

.notReqClass

{

    background:White;

}

 

</style>

</head>

<body>

<form id="form1" runat="server">

<div>

<asp:Panel ID="Panel1" runat="server" class="oneClass"> 

    Panel 1

</asp:Panel>

<asp:Panel ID="Panel2" runat="server" class="oneMoreClass">

    Panel 2

</asp:Panel>

<asp:Panel ID="Panel3" runat="server" class="oneClass">

    Panel 3

</asp:Panel>

<asp:Panel ID="Panel4" runat="server" class="notReqClass">

    Panel 4

</asp:Panel>

<asp:Panel ID="Panel5" runat="server" class="oneClass">

    Panel 5

</asp:Panel>

</div>

</form>

</body>

</html>
