从Json获得价值？

Question

嗨我有这个json数据

   var json = { "@@lang": "en-US", "ResultSet": { "@@version": "2.0", "@@lang":   "en-US", "Error": "0", "ErrorMessage": "No error", "Locale": "en-US", "Found": "1", "Quality": "99", "Results": [{ "quality": "72", "latitude": "30.778864", "longitude": "76.686648", "offsetlat": "30.778864", "offsetlon": "76.686648", "radius": "400", "name": "30.78,76.69", "line1": "30.78,76.69", "line2": "", "line3": "Mohali, Sahibzadaajit Singh Nagar, Punjab", "line4": "India", "house": "", "street": "", "xstreet": "", "unittype": "", "unit": "", "postal": "", "neighborhood": "", "city": "Mohali", "county": "Sahibzadaajit Singh Nagar", "state": "Punjab", "country": "India", "countrycode": "IN", "statecode": "PB", "countycode": "", "uzip": "", "hash": "", "woeid": "2290786", "woetype": "7"}]} };

我需要倒数第二个值--woeid：2209786

如何使用json获取此值？

Answer 1

你可以用'。'来浏览对象。运算符，因为结果在数组中使用'[]'并获得所需的对象... 试试这个。

var val=json.ResultSet.Results[0].woeid
alert(val);

Answer 2

试试这个：

json.ResultSet.Results[0].woeid

Answer 3

使用这种方式：

alert(json.ResultSet.Results[0].woeid);

Answer 4

json.ResultSet.Results[0].woeid
