ajax调用序列化和反序列化数据

Question

I have the following ajax call:

$(document).ready(function() {
            $.ajax({
                type: "POST",
                url: "/LoadCount.aspx/GetCounts",
                contentType: "application/json; charset=utf-8",
                data: "",
                async: false,
                dataType: "json",
                success: function(data) {
                  var myObj = JSON.parse(data.d);
                  alert(myObj.length);
                  for (var i = 0; i < myObj.length; i++) {
                    alert(myObj[0]);
                  }

                },
                error: function(xhr, status, error) {
                    var err = eval("(" + xhr.responseText + ")");
                    alert(err.Message);
                }
            });
        });

I am getting undefined when I alert the length

Here's my Method in my LoadCount.aspx

[WebMethod]
    public static string ObtenerContador()
{
    List<MenuItem> menu =(List<MenuItem>)HttpContext.Current.Session["MenuItems"];

    Dictionary<string, int> dic = new Dictionary<string, int>();
    foreach (MenuItemAMostrar item in menu)
    { 
        dic.Add(item.ControlID,1);
    };

    return new JavaScriptSerializer().Serialize(dic); //or any other suggested serialization method
}

this is what I am getting in the success function:

{"MenuCLESAAsignar":1,"MenuOCGestores":1,"MenuOcAAutorizar":1,"MenuOcAAutorizarBanco":1,"MenuOCGestoresObservadas":1,"MenuCLESActivos":1,"MenuParametros":1,"MenuCLESConAddendaAAprobarSup":1,"MenuPendienteAprobacion":1,"MenuConsultaCLES":1}

The question is, how do I deserialize that dictionary in my ajax success function? Once deserialized, how do I populate it, obtaining the data?

thanks!

Answer 1

Are you looking for this?

success: function (data)
{               
    var myObj = JSON.parse(data.d);
},

Answer 2

As somebody else mentioned, you just use JSON.parse() to parse the data.

From there it just creates an object, and you can access the data with . .

Like so:

http://jsfiddle.net/SJGLF/1/

var myData = JSON.parse(jsonData);
for(var i in myData)
{
    console.log(i + " = " + myData[i]);
}
