qwrap-object的dump

 

    

    本文载入qwrap一个dump的函数设计：

    

/**
 *@param {Object} obj
 *@param {Array} props 
 *@example ObjectH.dump({"name":"zhang","id":1,"age":20},["name","id"])  
 *返回：{name:"zhangyaochun",id:1}
/
dump:function(obj,props){
      //定义返回值类型
      var ret = {};

      //支持props为array,进行遍历
      for(var i = 0,len = props.length;i<len;i++){
          
             if(i in props){
                     var key = props[i];

                     if(key in obj){
 
                            //往ret里面装key,obj[key]
                            ret[key] = obj[key];
                     }
             }

     }

      return ret;

}
