{"event1":{"title":"My birthday","start":"12\/27\/2011 10:20 ","end":"12\/27\/2011 00:00 "},"event2":{"title":"My birthday again","start":"12\/27\/2011 10:20 ","end":"12\/27\/2011 00:00 "}}

and i want to parse it like

[
            {
                title: 'All Day Event',
                start: new Date(y, m, 1)
            },
            {
                title: 'Long Event',
                start: new Date(y, m, d-5),
                end: new Date(y, m, d-2)
            }]

How will i do this. i wrote this code but its givin array length 0 my code is

var response = eval(data);
        $.each(response, function() {
            obj = {};
            $.each(this, function(k, v) {
                if(k=="start")
                {
                    obj[k] = new Date(v);
                }
                if(k=="end")
                {
                    obj[k] = new Date(v);
                }
                else
                {
                    obj[k] = v;
                }
                event_data.push(obj);

            });

        });

Your parsed array got almost nothing to do with the original JSON - please be more clear about the logic involved and post correct example. – Shadow Wizard Dec 26 '11 at 9:10

Please do not use eval to parse JSON at all. – naveen Dec 26 '11 at 9:14

data = JSON.parse('{"event1":{"title":"My birthday","start":"12\/27\/2011 10:20 ","end":"12\/27\/2011 00:00 "},"event2":{"title":"My birthday again","start":"12\/27\/2011 10:20 ","end":"12\/27\/2011 00:00 "}}')

arr = []
for(var event in data){
    var dataCopy = data[event]
    for(key in dataCopy){
        if(key.match(/start|end/)){
            // needs more specific method to manipulate date to your needs
            dataCopy[key] = new Date(dataCopy[key])
        }
    }
    arr.push(dataCopy)
}

alert( JSON.stringify(arr) )

My code: 

var datas = '{"event1":{"title":"My birthday","start":"12\/27\/2011 10:20 ","end":"12\/27\/2011 00:00 "},"event2":{"title":"My birthday again","start":"12\/27\/2011 10:20 ","end":"12\/27\/2011 00:00 "}}';

var dataObj = eval("(" + datas + ")");
var finalArr = [];
for(var i in dataObj) {
    var t = dataObj[i];
    finalArr.push({
        title: t.title,
        start: new Date(t.start),
        end: new Date(t.end)
    });
}

console.log(finalArr);

Why use eval when JSON.parse is built into browsers now? – Amaan Cheval Dec 26 '11 at 9:42
@Amaan for Compatibility. such is IE6... – ijse Jan 5 '12 at 9:41
@Amaan or we can use RegExp() to parse JSON manually. – ijse Nov 12 '12 at 6:55

It looks like you're already using jQuery so just use $.parseJSON. (http://api.jquery.com/jQuery.parseJSON/)

You'll have to iterate over the object that is created though to turn the date strings into Date objects.

var data = {
    "event1": {
        "title": "My birthday",
        "start": "12\/27\/2011 10:20 ",
        "end": "12\/27\/2011 00:00 "
    },
    "event2": {
        "title": "My birthday again",
        "start": "12\/27\/2011 10:20 ",
        "end": "12\/27\/2011 00:00 "
    }
};

var response = eval(data);
var events = [];
$.each(response, function(key, event) {
    var obj = {};
    for (var prop in event) {
        obj[prop] = event[prop];
    }
    obj["start"] = new Date(obj["start"]);
    obj["end"] = new Date(obj["end"]);
    events.push(obj);
});


console.log(events);
