[Asp.net] MVC Controller 에서 jQuery로 동적으로 데이터 얻는 방법

How to get data from ASP.NET MVC controller to jQuery dynamically?

Here is the code for how you send data from Controller to json:

 $.ajax({
    url: '@Url.Action("GetData", "Home")',
    type: "GET",
    success: function (result) {
        $("#somediv").append(result.FirstName);
        $("#somediv").append(result.LastName);
        $("#somediv").append(result.Age);
    }
});

Consider a class like the one below....

 public class User
    {
        public string FirstName { get; set; }
        public string LastName { get; set; }
    }

your action should look like this.

public JsonResult GetData(){

User user = new User();
user.FirstName = "Yasser";
user.LastName = "Shaikh";
user.Age = 100;

return Json(user, JsonRequestBehavior.AllowGet);
}

You can make use of the jquery ajax function and the MVC Razor Url property:

$.ajax({
    url: '@Url.Action("Home")',
    type: "GET",
    success: function (data) {
        $("my-div").append(data);
    }
});

The value of the success property is a function with one argument: data. This is the result of what is returned from your controller.

Javascript:

$.ajax({
        type: 'POST',
        url: '@(Url.Action("SomeAction", "SomeController"))',
        data: someInputData,
        error: OnErrorFunction,
        success: function (data, textStatus, XMLHttpRequest) {
            alert(JSON.stringify(data));
        },
        dataType: "json"
    });

Controller:

public ActionResult SomeAction(InputDataType someInputData)
    {
        if (someInputData== null)
            return null;
        return new JsonResult {Data = SomeOutputData(someInputData)};
    }
