获取Object的所有keys or values

有的时候，我们需要操作Object中的key和value,我们需要获取对应的所有keys或者values

 

先看看prototype的api设计吧：

 

/*
获取keys
*/
keys:function(obj){
   var keys = [];
   for(var pro in obj){
      keys.push(pro);
   }
   return keys;
}

/*
获取values
*/
values:function(obj){
    var values = [];
    for(var pro in obj){
      values.push(obj[pro]);
   }
    return values;
}

 

 

 

 

 

 

 

1、获取Object对应的keys

 

 

/*
*keys-get a array contains all the keys in object*
*@function*
*@param {Object} source*
*@return {Array}*
*@mark we have not check the source is or not object*
*/
ZYC.object.keys = function(source){
    var result=[],
          key,
          _length=0; 
    for(key in source){
	   if(source.hasOwnProperty(key)){
	      result[_length++] = key;
	   }
	}
    return result;
};

 

 

 

2、获取Object对应的values

 

 

/*
*values-get a array contains all the values in object*
*@function*
*@param {Object} source*
*@return {Array}*
*@mark we have not check the source is or not object*
*/
ZYC.object.values = function(source){
    var result=[],key,_length=0;
	for(key in source){
	  if(source.hasOwnProperty(key)){
	     result[_length++] = source[key];
	  }
    }
	return result;
};
