Javascript JSON解析-带数组的查询

给出以下查询：

{"ResultSet":{"version":"1.0","Error":0,"ErrorMessage":"No error","Locale":"us_US","Quality":40,"Found":1,"Results":[{"quality":40,"latitude":"37.777125","longitude":"-122.419644","offsetlat":"37.777125","offsetlon":"-122.419644","radius":10700,"name":"","line1":"","line2":"San Francisco, CA","line3":"","line4":"United States","house":"","street":"","xstreet":"","unittype":"","unit":"","postal":"","neighborhood":"","city":"San Francisco","county":"San Francisco County","state":"California","country":"United States","countrycode":"US","statecode":"CA","countycode":"","uzip":"94102","hash":"","woeid":2487956,"woetype":7}]}}

我如何得到“uzip”

警报（data.ResultSet.Results）有效 但是： 警报（data.ResultSet.Results.uzip）
表示“未定义” alert（data.ResultSet.Results[uzip]）也是如此。

谢谢。

里面有一个数组。像这样访问它

data.ResultSet.Results[0].uzip

---

请尝试

data.ResultSet.Results[0]。zip

---

注意：结果数组包含一个对象，您需要获取数组中的第一个元素，然后访问其中的组件。

data.ResultsSet.Results[0].uzip如何
