javascript - 如何获取json对象中的特定值？-PHP中文网问答-javascript - 如何获取json对象中的特定值？-PHP中文网问答

围观一下哦，学习一下。

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/)

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"};
