How to create a method in the MVC Controller so that it becomes AJAX Callable?

How to create a method in the Controller so that it becomes AJAX Callable?

For example, code {0} can be accessed using {1} when the return type is ActionResult:

{0}:
public ActionResult TestWithActionResult(string id)
        {
            return View();
        }

{1}:
http://localhost:4574/ControllerName/TestWithActionResult/2

but my below code {3} can't be accessed with {4}:

{3}:
    public string TestWithString(string id)
            {
                return "some string";
            }
{4}:
http://localhost:4574/ControllerName/TestWithString/2

the id in the {3} is always null when I open {4}.

Should I decorate {3} differently? How?

Thanks,

Your method needs to return an ActionResult of some kind (or ViewResult, JsonResult, etc) to be considered an Action. You could just use a JsonResult to write the text to the Response.

public ActionResult TestWithActionResult(string id)
{
  return new Json("some string");
}

Try using a JsonResult:

public JsonResult TestWithActionResult(string id)
{
    return Json("Some string");
}

Edit:

You can call the function using AJAX like this (using Jquery)

$.ajax( 
   url: 'http://localhost/TestWithActionResult/feed1',
   type:'GET',
   dataType: 'json',
   success: function(data) { 
         //Process data
   },
   error: function(error) { }
);
