JQuery Postback with Webforms

We are redesigning the main part of our website and instead of using a 90KB AJAX file, I would rather use a jQuery 1900 script.

I've seen the following articles:

The thing I am not getting is how to do the postback for a specific method, either in code or in another class.

I know in ASP.NET-MVC I can post back to a controller / action. How can I call a specific method in WebForms?

Something along the lines; $ .post ("class and action", (parameter: value} ......

Any thoughts, code, etc.

It is very easy to call certain encoded methods. Here's a nice article with all of Dave's details.

Just declare the method like this:

 [WebMethod]
  public static string GetDate()
  {
    return DateTime.Now.ToString();
  }

This is all you need in jQuery:



$.ajax({
  type: "POST",
  url: "PageName.aspx/MethodName",
  data: "{}",
  contentType: "application/json; charset=utf-8",
  dataType: "json",
  success: function(msg, status, xhr) {
    // Do something interesting here.
  }
});

Caveats:

  • WebMethod

    must be on a static method
  • Be sure to line the posted data when sending anything (i.e. JSON.stringify(yourDataObject)

    ) will deserialize according to the method parameters
  • msg

    - the answer, the return result of your method is in the property msg.d
