Question

here is my project hirarchy:

from browser.js I’m trying to call ManagerController:

 $("#jstree").jstree({
        "json_data": {

    "ajax": {   


                type: "GET",
                async: true,
                "url": "Controllers/Manager/Getlocations?userId='1234'",
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                cache: false,
                success: function (msg) {                         
                        return msg;
                },
                error: function () {
                    // TODO process error
                }
            },

//continuation is less relevant

But I get the following error in chrome console:

GET
http://localhost:1186/MainUgi/Controllers/Manager/Getlocations?userId=‘1234’&_=1324071607446
404 (Not Found)

1) what should be the right path ?

2) what is the &_=1324071607446 which is concatinated to the end of my get request?

update

my controller looks like:

  public class ManagerController : Controller
    {

        public JsonResult GetLocations(string userId)
        {
            var locationsJson = 
            new {[  {"data": "[0]", .. some data...}  ]};

            return Json(locationsJson, JsonRequestBehavior.AllowGet);
        }

my request looks like:

Answer 1

The basic MVC url mask is the following:

/{CONTROLLER}/{ACTION}?{...PARAMETERS}

By your example we have:

'/manager/getLocations?userId=1234'

And the controller should have the following code (example):

[ControllerAction]
public void getLocations( int userId ) {
    ViewData["UserId"] = userId;
    RenderView("GetLocations");
}

Now you need to have a view file to show the content. Create a folder (inside the root of the project), named “View”, and inside it, create another one with the name of the controller (Manager), and create a view file called “GetLocations.aspx” (the one that we want asked to render).

To print the UserId variable in the view:

<%= ViewData["UserId"] %>

If it doesn’t work, it’s better for you to read a lot about the MVC Pattern. You can start here.
