Question

我试图用jquery读取这个json文件中的media_url链接。由于某种原因，我无法到达我的页面所需的media_url。这就是我的尝试：

console.log(data) <---- gives the whole file and works fine
console.log(data.statuses.media.media_url) <----- undefined

继承了底部附近的media_url的json文件：

{"statuses":[
{"metadata":
{"iso_language_code":"de","result_type":"recent"},
"created_at":"Wed Oct 01 09:56:09 +0000 2014","id":5.1725161318738e+17,"id_str":"517251613187379200",

我希望有人知道如何解决这个问题！

感谢您的帮助！

除了缺少逗号之外，你错过了JSON（实体）中的一个父元素：

<强> data.statuses [0] .entities.media [0] .media_url

JSFiddle：http://jsfiddle.net/TrueBlueAussie/wrz903kx/1/

alert(data.statuses[0].entities.media[0].media_url);

如果您使用http://jsonformatter.curiousconcept.com/之类的工具，则可以展开层次结构并导航对象。
