Make an AJAX request using $.ajax in MVC 4

问题:

I am trying to make an AJAX request using $.ajax in MVC 4 with Razor. I'm not sure how to implement it.

Using this video I was able to successfully make a link-driven call that returned data, but I can't seem to do the same thing from inside a jquery function. I can't seem to find any basic examples of how to do this. This is what I am working with:

HomeController.cs

        public string test(){
             return "It works";
        }

View.cshtml

function inventory(dealerID) {
    $.ajax({
        url: '@Url.Action("HomeController","test")',
        data: {dealerID: dealerID},
        type: 'POST',
        success: function(data) {
            process(data);
        }
    });
}

You just need to make it an ActionResult. Also, if you're using an Ajax POST, then the action needs to be marked with the HttpPost attribute. Try this:

[HttpPost]
public ActionResult test(string dealerID)
{
    return Content("It works");
}

Edit Actually, there are a few other problems with the syntax.

1. Url.Action has the controller/action parameters in the wrong order -- should be "ActionName" first, then "ControllerName"
2. For Url.Action, if the controller class is "HomeController", then you need just "Home"
3. The JQuery options syntax is wrong -- should be success: function(data) {}.

$.ajax({
    url: '@Url.Action("test", "Home")',
    data: {dealerID: dealerID},
    type: 'POST',
    success: function(data) {
        alert(data);
    }
});
