if(typeofCat.initialized=="undefined"){ Cat.prototype.sayHello=function(){ alert("喵喵!"); } Cat._initialized=true; } } 该方法使用标志(_initialized)来判断是否已给原型赋予了任何方法。该方法只创建并赋值一次,与传统的OOP语言,这样的代码更像其它面向对象语言中的定义。 总结 javascript自定义对象主要...

We can loop through all the elements in the array using either for loop or forEach loop. We have already seen for a loop when we created and initialized our array. Let us now try to get the sum of all the elements in our array using a forEach loop. ...
