C#JSONP Request Background Instance (iii)

Question 3: Don't ask me why I do this system to use JSONP, I do not want to say, very tired

Solve:

Front-End Code:

$.ajax ({
    type: ' Get ',
    URL: "url",
    dataType: ' Jsonp ',
    jsonp: "Callback",
    Jsonpcallback: " Jsonpcallback ",

    success:function (data) {
    },
    error:function () {
    }
})

Back-End Code:

Dbmodels db = new Dbmodels ();//Custom database Request Model
DataSet Returndata = Db.select ("SELECT * from user");
String json = Newtonsoft.Json.JsonConvert.SerializeObject (returndata);
Response.Write ("Jsonpcallback (" + JSON + ")");

Experience: The key here is to add jsoncallback, in the best return string stitching on the line.
