JS擷取對象的key和value

有的時候，我們需要操作Object中的key和value,我們需要擷取對應的所有keys或者values
1、擷取Object對應的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、擷取Object對應的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; 
    };
