在javascript中解析Json对象

Question

你好，所有我有一个像这样的json对象

{"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 "}}

我想像这样解析它

[
            {
                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)
            }]

我该怎么做呢。我写了这段代码，但它的数组长度为0，我的代码是

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);

            });

        });

Answer 1

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 == "start" || key == "end"){
            // needs more specific method to manipulate date to your needs
            dataCopy[key] = new Date(dataCopy[key])
        }
    }
    arr.push(dataCopy)
}

alert( JSON.stringify(arr) )

看起来你已经在使用jQuery了，所以就用$.parseJSON吧。(http://api.jquery.com/jQuery.parseJSON/)

您必须遍历所创建的对象，才能将日期字符串转换为date对象。

Answer 3

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);
