本文详细介绍了如何通过JavaScript操作用户数据列表，包括遍历、提取特定属性等基本操作。

var list = {'list':[{"id":8,"password":"月月","username":"维吾尔"},
 {"id":7,"password":"dfgsfdf","username":"dfdfdf"},
 {"id":6,"password":"aaabbb","username":"aaaabbb"},
 {"id":5,"password":"gfdfgdf","username":"fggegte"},
 {"id":3,"password":"dfgfgrewr","username":"hahaha"},
 {"id":2,"password":"fggfhgfh","username":"fddgfgh"},
 {"id":1,"password":"hdghdgd","username":"dfsgss"}]};
 
 
for(var l in list){    
    alert(l+"  "+list[l]);
    for(var c in list[l]){
        alert(list[l][c].id+"  "+list[l][c].password+"  "+list[l][c].username);
    }
}
 
for(var l in list){    
    alert(l+"  "+list[l]);
    for(var c in list[l]){
        for(var _c in list[l][c]){
            alert(_c+"  "+list[l][c][_c]);
        };
    }
}
 
var li = [{"id":8,"password":"月月","username":"维吾尔"},
 {"id":7,"password":"dfgsfdf","username":"dfdfdf"},
 {"id":6,"password":"aaabbb","username":"aaaabbb"},
 {"id":5,"password":"gfdfgdf","username":"fggegte"},
 {"id":3,"password":"dfgfgrewr","username":"hahaha"},
 {"id":2,"password":"fggfhgfh","username":"fddgfgh"},
 {"id":1,"password":"hdghdgd","username":"dfsgss"}];
 
for(var i in li){
    alert(i+"  "+li[i]);
    for(var _i in li[i]){
        alert(_i+"  "+li[i][_i]);
    }   
}
