ASP.Net WebMethod

One day I thought, how convenient it would have been if I could call a server method from my client script on my web page, simply, as I can call a javascript method from another javascript method.
And yes, there is the asp.net WebMethod attribute with which we can do a sever method calling as calling a method locally. WebMethod with JQuery and a little bit of JSON and we are done.
Here is the code snippet to implement the same:

Asp.Net Code

[WebMethod] 

public static string ServerMethod(string name)

{    
     return "Hi " + name;
}

WebMethod attribute requires reference to System.Web.Services.
And remember to mark the method static, otherwise it will not work.

Client Script

function GetResultFromServer()
{
   $.ajax({ type:"post",
   url: "Default.aspx/ServerMethod",
   data: JSON.stringify({name:"Boraska"}),
   contentType: "application/json; charset=utf-8",
   dataType: "json",
   success: function (data) {
      alert("Hurreyyy! I got " + data.d + "from server method.");
      }
  });}

This small script and WebMethod attribute do the fantastic job, no need to go in detail of page life-cycle events and many more things.
Now, here again, there are few things that needs to be taken care to make this work:

• Url contains the method name which you want to call. Specify the url carefully. If you need you can pass query strings as well with url.
• Data is the parameters you want to pass to the server method. The name and number of parameters must match to the server method what you are passing from here.
• More than one parameters can be passed to the method but their types should be compatible, I mean you can pass "abc" to object type parameter but not to int type of parameter in the server method.
