Question

Code Behind:

 [WebMethod]
        public static string emp()
        {
            return "BlaBla";
        }

Aspx Page:

$(document).ready(function() {

          $.get("TestPage.aspx/emp", null, function(data) {

                alert(data);

      })
     })

Message Box Output: TestPage.aspx on the page codes

<!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><title>
</title>    
    <style>    
        tr    
        {
                background-color: red;
                color: White;    
        }
        </style>

use

$(document).ready(function() {
  // Add the page method call as an onclick handler for the div.
  $("#Result").click(function() {
    $.ajax({
      type: "POST",
      url: ""TestPage.aspx/emp",
      data: "{}",
      contentType: "application/json; charset=utf-8",
      dataType: "json",
      success: function(msg) {
        // Replace the div's content with the page method's return.
        $("#Result").text(msg.d);
      }
    });
  });
});

In your page use

<div id="Result">Click here to return the string</div>

The code behind method also needs to be static, and decorated with ScriptMethod as well as WebMethod.

Then use jQuery instead, like Pandiya has shown. The important bit in the article is how your method in the code-behind file should be developed.

$("#Result").text(msg.d); Why is being used ".d" ?
