Question

How do you return a serialized JSON object to the client side using ASP.NET MVC via an AJAX call?

Answer 1

From the controller you can just return a JsonResult:

public ActionResult MyAction() {     ... // Populate myObject     return new JsonResult{ Data = myObject }; } 

The form of the Ajax call will depend on which library you’re using, of course. Using jQuery it would be something like:

$.getJSON('/controllerName/MyAction', callbackFunction); 

where the callbackFunction takes a parameter which is the data from the XHR request.
