Question

我有一个像这样的JSON字符串：

{"time":"2011-11-30 04:44","countryName":"Austria","sunset":"2011-11-30 16:32","rawOffset":1,"dstOffset":2,"countryCode":"AT","gmtOffset":1,"lng":10.2,"sunrise":"2011-11-30 07:42","timezoneId":"Europe/Vienna","lat":47.01}

我如何使用javascript解析这个？我尝试过使用：

function callbackFun(data) {
        $j.each(data.result, function(i, item) {
            alert(this.time);
        });
    }

但似乎这不正确。

Answer 1

如果您从$.ajax()检索该数据，则可以设置dataType: 'json'以自动为您解析。

否则只需使用$.parseJSON()

Answer 2

如果你正在使用jQuery，那很简单：

var obj = '{"time":"2011-11-30 04:44","countryName":"Austria","sunset":"2011-11-30 16:32","rawOffset":1,"dstOffset":2,"countryCode":"AT","gmtOffset":1,"lng":10.2,"sunrise":"2011-11-30 07:42","timezoneId":"Europe/Vienna","lat":47.01}';

var json = jQuery.parseJSON(obj);
alert(json.time);
alert(json.countryName);

你在找这个吗？

var MyJson = '{"time":"2011-11-30 04:44","countryName":"Austria","sunset":"2011-11-30 16:32","rawOffset":1,"dstOffset":2,"countryCode":"AT","gmtOffset":1,"lng":10.2,"sunrise":"2011-11-30 07:42","timezoneId":"Europe/Vienna","lat":47.01}';

var MyObject = jQuery.parseJSON(MyJson);
