    "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,对于服务器返回的json数据,如何获取Link中第一个@attributes的href值?

var req = { ...你的返回对象... };
var first_href_val = req.link[0]['@attributes'];

There is the json site(http://www.json.org/), it lists the tutorial of all languages supporting json.
May be it is helpful.

for python(http://docs.python.org/library/json.h...)
for ruby(http://flori.github.com/json/)

小葫芦

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; }

采用递归方式来查找josn中的你需要的key.

但是还不支持 数组,你可以自己扩充,思路就是这样!

var taskId = getJsonValue(jsonobj,"history");
console.log(taskId);
var jsonobj = { "semantic":{"taskId":"8.4.3"},"history":"cn.xxxx.fund"};
