Ajax, JSON some finishing (1)

1. Request text data for manual parsing in the success event

Front Desk: $.ajax ({type: "post", url: "Checkfile.ashx", Data: {"filename": "2"}, dataType: "Text",Success:function (data) {var json = eval (' (' + data + ') '); Alert (JSON.                    Age); }); background processing: HttpResponse res = context.            Response; HttpRequest req = context.            Request; String code = req["FileName"];string jsonstring = "{\" age\ ": 28,\" name\ ": \" Zhang San \ "}";//string jsonstring = "{' Age ':", ' Name ': ' abc '} ";if (code! = null) {Res. Write (jsonstring); Res. ContentType = "Text/plain";Res.            End (); } in this case, both single-quote and transfer-double-quote splits are possible.         2. Request JSON format data, jquery automatic parsingFront Desk: $.ajax ({type: "post", url: "Checkfile.ashx", Data: {"filename": "3"},//ContentType: "Application/json",----------This property cannot be specified when AJAX requests JSON data for a ashx file, but must be specified when requesting webservices.                     DataType: "JSON",                    success:function (data) {                &NBSP ;       alert (data. Name);                   }            &NB Sp  );  background processing:            HttpResponse res = context. response;            HttpRequest req = context. request;            String code = req["FileName"];           s Tring jsonstring = "{\" age\ ": 28,\" name\ ": \" Zhang San \ "}";            if (code! = null)             {                Res. Write (jsonstring);                Res. ContentType = "TeXt/plain ";                Res. End ();           } in this case, only the transfer of double quotation marks can be automatically parsed in the foreground by the jquery method.     3. Foreground parsing of text data with serializationFront desk:                $.ajax ({                    Type: "POST",                    URL: "Checkfile.ashx", &N Bsp                   data: {"filename": "2"},        &NBSP ;           DataType: "text",                    Success:function (data) {                        $ ("P"). Text ( Data);                        var json = eval (' (' + data + ') ' );                        alert (JSON. Name);                   }            &NB Sp  }); JSON data content: {"Name": "Zhangsan", "Code": 111, "Birthday": "\/date (649666800000) \"}Background processing: HttpResponse res = context.            Response; HttpRequest req = context.            Request;            String code = req["FileName"]; Student stu = new Student {name= "Zhangsan", code=111, Birthday=convert.todatetime ("1990            -8-3 ")};            JavaScriptSerializer serializer=new JavaScriptSerializer (); String jsonstring = serializer. Serialize (Stu); JSON data content: "{\" name\ ": \" zhangsan\ ", \" code\ ": 111,\" birthday\ ": \" \\/date (649666800000) \\/\ "}"if (code! = null) {Res.                Write (jsonstring); Res.                ContentType = "Text/plain"; Res.            End ();        } [Serializable] public class Student {public string Name {get; set;}        public int Code {get; set;}    Public DateTime Birthday {get; set;} }

4. JSON with serialized foreground auto parse: Front desk: $.ajax ({type: "post", url: "Checkfile.ashx", Data: {"filename": "3"},dataType: "JSON",--------------as long as you specify here, background processing ibid. Success:function (data) {alert (data).                    Name); }                });
