JQuery isn't parsing JSON response properly

问题

I am using jQuery fullcalendar plugin , I have tried altering this many different ways from answers to other questions with no luck, here is my jQuery:

         $(document).ready(function () {

    var date = new Date();
    var d = date.getDate();
    var m = date.getMonth();
    var y = date.getFullYear();

    $('#calendar').fullCalendar({
        theme: true,

        aspectRatio: 3,
        height: 1000,
        header: {
            left: 'prev,next today',
            center: 'title',
            right: 'month,agendaWeek,agendaDay'
        },
        editable: true,
        events: function (start, end, callback) {
            $.ajax({
                type: "POST",
                url: "Default.aspx/GetEvents",
                data: "{'userID':" + "'B473795D-306A-4718-804B-2813884D5B48'}",
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                success: function (doc) {
                    var events = [];
                    var obj = $.parseJSON(doc.d);
                   var res = unescape(obj);
                    $(res).find('event').each(function () {
                        events.push({
                            title: $(this).attr('title'),
                            start: $(this).attr('start') // will be parsed
                        });
                    });
                    callback(events);
                }
            });
        }
    });
});

Here is my response :

  {"d":"[{ \"title\"  : \"circleJerk\", \"start\"  : \"2012-06-22\" }, { \"title\"  : \"BangTheWife\", \"start\"  : \"2012-06-15\" , \"end\" : \"2012-06-23\" } ]"}

Your return type from your method GetEvents is string isn't it?

Try returning a List<Event> (or whatever your object is called) and then you don't need to go through the mess of unescaping a JSON string.

$.ajax({
    type: "POST",
    url: "Default.aspx/GetEvents", //return type List<Event>
    data: "{'userID':" + "'B473795D-306A-4718-804B-2813884D5B48'}",
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function (doc) {
        //doc.d = [Event,Event,Event] (no processing needed)
        callback(events);
    }
});

In response to your comment, a method with return type of List<> will look like :

[{"title": "sometitle", "start": "yourData"},{"title":"someTitle2", "start":"yourStart2"}]

Translating ASP.NET ASMX webmethod DateTime serialization to JavaScript Date object:

DateFromASPNET = function (sNetDate) {
    if (sNetDate == null) return;
    var r = /\/Date\(([0-9]+)\)\//i
    var matches = sNetDate.match(r);
    if (matches.length == 2) {
        return new Date(parseInt(matches[1]));
    }
    else {
        return sNetDate;
    }
}

The problem is that AJAX is aysnchronous so by passing a function to events option, nothing is returned due to the AJAX call.

Use the built in AJX methods of the plugin by simply passing a ajax options to eventsources option.

From Docs: http://arshaw.com/fullcalendar/docs/event_data/events_json_feed/

$('#calendar').fullCalendar({
   eventSources: [

    // your event source
    {
        url: "Default.aspx/GetEvents",
        contentType: "application/json; charset=utf-8",
        type: 'POST',
        data: "{'userID':" + "'B473795D-306A-4718-804B-2813884D5B48'}"
    }

 ]
});

EDIT: can also pass single event source ajax options object to events option per docs
