代码 var DataCache = function(){
    if(!(this instanceof DataCache)){
        return new DataCache();
    }
    this.id = 0;
    this.caches = {};
};
DataCache.prototype = {
    add : function(val){
        val = val || null;
        key = "dc_" + this.id;

        this.caches[key] = val;
        return key;
    },
    remove : function(key){
        delete this.caches[key];
    },
    get : function(key){
        return this.caches[key];
    },
    set : function(key,val){
        this.caches[key] = val;
    }
};
