JAVASCRIPT

Here I will explain how to integrate Web Methods through javascript with 5 steps.

Step1: We have to add meta tag in the Header of the Document

    <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"/>

Step2: We have write function in server side like below; method name should be with webmethod tag like below

 $.ajax(

        {

            type: "POST",

            url: "CheckUser.aspx/CheckAccessRights",            data: "{}",

            contentType: "application/json; charset=utf-8",

            dataType: "json",

            success: function(msg)

                     {

                        //something

                        accessValue=msg;

                     }

        }

    );

Step3: We have to call the server side method from the client side

Step4: Add Script Tag, create one variable in as arrary

   <script language="javascript" type="text/javascript">

    var accessValue;

   <script/>

Step5: Create method from server side and add attribute [Webmethod] like below.

 [WebMethod]

    public string CheckAccessRights()

    {

        return "valid";

    }
