常用工具判断-isFunction

 

判断对象是否是function

 

   先看看prototype 1.6.0

 

isFunction:function(obj){
   return typeof obj == "function";
}

 

 

 

 

/*
*isFunction-judge the source is or not function*
*@function*
*@param source*
*@return {boolean}*
*/
ZYC.lang.isFunction = function(source){
    return Object.prototype.toString.call(source) === "[object Function]";
};
