javascript apply方法
JavaScript的每个function对象都有一个apply方法
语法如下：funtion.apply([thisObj[,argArray]])
功能说明：将一个函数的对象上下文从初始的上下文改变为由thisObj指定的新对象，用来模拟多态
/**method 声明**/function Object1(name) { this.name = name; this.fun1 = function(){ alert("this is first method !"); }; this.fun2 = function() { alert("this is second method !"); };}function Object2(name) { Object1.apply(this,[name]); //Object1.apply(this,["hahahhah"]);}/**method 调用**/ var o2 = new Object2("china"); o2.fun1(); //alert("this is first method!"); o2.fun2(); //alert("this is second method!"); alert(o2.name+"==================apply method!");//alert(china=============apply method!);
