I want to set text to label with jQuery after clicking on button. I wrote code and it works, but after I set text in my label, label return his old state. Here is my code:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm2.aspx.cs" Inherits="DynamicWebApplication.WebForm2" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script>
<script type="text/javascript">
function f()
{
$('#<%=Label1.ClientID%>').html("hello");
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Label ID="Label1" runat="server"></asp:Label>
<p></p>
<asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="f();"/>
</div>
</form>
</body>
</html>

If your button is causing a postback then the changes will be lost after the page has reloaded. Try this -
function f()
{
$('#<%=Label1.ClientID%>').html("hello");
return false;
}
