Examples

The following example shows how to return an instance of the JsonResult class from an action method. The object that is returned specifies that a GET request is permitted.

public ActionResult Movies()
{
    var movies = new List<object>();

    movies.Add(new { Title = "Ghostbusters", Genre = "Comedy", Year = 1984 });
    movies.Add(new { Title = "Gone with Wind", Genre = "Drama", Year = 1939 });
    movies.Add(new { Title = "Star Wars", Genre = "Science Fiction", Year = 1977 });

    return Json(movies, JsonRequestBehavior.AllowGet);
}

The next example shows how to retrieve and display the JSON-formatted content.

<input name="btnGetMovies" id="btnGetMovies" type="submit" value="Get Movies">
<ul id="movieList"></ul>

<script src="~/Scripts/jquery-1.10.2.js"></script>
<script type="text/javascript">
    $("#btnGetMovies").click(function () {
        var actionUrl = '@Url.Action("Movies", "Home")';
        $.getJSON(actionUrl, displayData);
    });

    function displayData(response) {
        if (response != null) {
            for (var i = 0; i < response.length; i++) {
                $("#movieList").append("<li>" + response[i].Title + " " + response[i].Genre + " " + response[i].Year + "</li>")
            }
        }
    }
</script>
