Flex 遍历Map

Flex中的Map其实是用Object来实现的。
赋值如下：

var map:Object = {};
map["key1"] = {userId: "user001", userName: "用户1", userAge: "31"};
map["key2"] = {userId: "user002", userName: "用户2", userAge: "32"};
map["key3"] = {userId: "user003", userName: "用户3", userAge: "33"};

遍历这个map的方法有两个：

1. for in

遍历key

var user:Object;
for (var key:String in map)
{
    user = map[key];
    // 略 各种其他操作
}

2. for each in

遍历value

for each (var user:Object in map)
{
    // 略 各种其他操作
}

以上
