I want to do very simple thing, but I'm not success. I have button and label on my asp.net page and I want to get text of label after clicking on button. 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 type="text/javascript">
        function f() 
        {
            var g = $('<%=Label1.ClientID%>').val();  // Also I tried .text() and .html()
            alert(g);
        }
    </script>
</head>

<body>
    <form id="form1" runat="server">
        <div>
            <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
            <p></p>
            <asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="f();"/>
        </div>
    </form>
</body>

No solution here worked for me. Instead I added a class to the label and was able to select it that way.

<asp:Label ID="Label1" CssClass="myLabel1Class" runat="server" Text="Label"></asp:Label>

$(".myLabel1Class").val()

And, as mentioned by others, make sure you have your jquery loaded.

for the line you wrote

var g = $('<%=Label1.ClientID%>').val(); // Also I tried .text() and .html()

you missed adding #. it should be like this

var g = $('#<%=Label1.ClientID%>').text();

also I do not prefer using this method

that's because if you are calling a control in master or nested master page or if you are calling a control in page from master. Also controls in Repeater. regardless the MVC. this will cause problems.

you should ALWAYS call the ID of the control directly. like this

$('#ControlID')

this is simple and clear. but do not forget to set

ClientIDMode="Static"

in your controls to remain with same ID name after render. that's because ASP.net will modify the ID name in HTML rendered file in some contexts i.e. the page is for Master page the control name will be ConetentPlaceholderName_controlID

I hope it clears the question Good Luck
