In ASP.NET MVC: All possible ways to call Controller Action Method from a Razor View

Method 1 : Using jQuery Ajax Get call (partial page update).

Suitable for when you need to retrieve jSon data from database.

Controller's Action Method

[HttpGet]public ActionResult Foo(string id){    var person = Something.GetPersonByID(id);    return Json(person, JsonRequestBehavior.AllowGet);}

Jquery GET

function getPerson(id) {    $.ajax({        url: '@Url.Action("Foo", "SomeController")',        type: 'GET',        dataType: 'json',        // we set cache: false because GET requests are often cached by browsers        // IE is particularly aggressive in that respect        cache: false,        data: { id: id },        success: function(person) {            $('#FirstName').val(person.FirstName);            $('#LastName').val(person.LastName);        }    });}
