1.首先在js裡建立一個getMap()函式

程式碼如下:

function getMap() {// 初始化map_,給map_物件增加方法，使map_像Map
var map_ = new Object();
map_.put = function(key, value) {
map_[key + '_'] = value;
};
map_.get = function(key) {
return map_[key + '_'];
};
map_.remove = function(key) {
delete map_[key + '_'];
};
map_.keyset = function() {
var ret = "";
for (var p in map_) {
if (typeof p == 'string' && p.substring(p.length - 1) == "_") {
ret += ",";
ret += p.substring(0, p.length - 1);
}
}
if (ret == "") {
return ret.split(",");
} else {
return ret.substring(1).split(",");
}
};
return map_;
}

2.建立map

var map = getMap();

map.put(k,v);

map.put(k1,v1);
