在jquery里面，分别要取到“all”的所有menuid和menuname，也要取到“user”的所有menuid和menuname

Answer 1

for(var i in json.all)
    console.log(json.all[i].menuid + ": " + json.all[i].menuname);
for(var i in json.user)
    console.log(json.user[i].menuid + ": " + json.user[i].menuname);

或者

for(var key in json) {
    for(var i in json[key])
        console.log(json[key][i].menuid + ": " + json[key][i].menuname;
}

里面的json就是你的json对象。如果是文本格式，就先用JSON.parse转化一下

Answer 2

for(var key in json){//key为键值 ，json[key]为value值
}
