``` { "id": "some", "title": "some", "author": { "name": "\u95eb\u9759" }, "link": [{ "@attributes": { "href": "http://localhost/", "rel": "some" } }, { "@attributes": { "href": "http://localhost/", "rel": "some" } }, { "@attributes": { "href": "http://localhost/", "rel": "some" } }] } ``` 如上，對于服務器返回的json數據，如何獲取Link中第一個@attributes的href值？ ``` var req = { ...你的返回對象... }; var first_href_val = req.link[0]['@attributes']; ``` ## 其他(不支持數組) ``` function getJsonValue(obj,name){ var result = null; var value = null; for(var key in obj){ value = obj[key]; if(key == name){ return value; } else { if( typeof value == "object" ){ result = getJsonValue(value,name); } } } return result; } ``` 采用遞歸方式來查找`josn`中的你需要的`key`. 但是還不支持 數組，你可以自己擴充，思路就是這樣！ ``` var jsonobj = { "semantic":{"taskId":"8.4.3"},"history":"cn.xxxx.fund"}; var taskId = getJsonValue(jsonobj,"history"); console.log(taskId); ```
