MVC Area和Ajax问题

Question

I have one Area Named Test. Inside this area, I have script folder which contains JS file. I am making one ajax call from this js to the controller in a Root directory. This is not working. Ajax call returns 302 found and call Index method of that controller.

How can I make this working?

Structure of Area TeasArea -> Scripts -> test.js

    $.ajax({
            type: "POST",
            url: url,
            data: $form.serialize(),
            dataType: "json",
            traditional: true,
            success: function (Res) {

value of url is '/controllername/Methodname', where this controller resides in Root directory's Controllers folder.

Note : I am generating this url using @Url.Action("MethodName", "ControllerName", new { area = "" });

Action Method in Controller looks like

public JsonResult sampleprint(FormCollection formData)
{
   /// Code goes here.
}
