目前,Im试图利用John Resigs简单的Javascript Inheritence 图书馆,这一图书馆发挥了巨大作用,但当我试图修改违约成员变量时,它似乎影响原型,而不是仅仅影响:

你可以看到,每当你创造新的榜样时,这些事件的长短不一。 我以错误的方式使用图书馆,还是这种众所周知的缺陷? 有哪些替代办法?

最佳回答

The problem here is that you are extending the class with events: []

参考文献有: 因此,通过扩大课程范围,每个班级都将有一个<条码>events,等于同一个参考阵列。

接下去

var Test = Class.extend({
    events: null,

    init: function() {
        this.events = [];
        this.events.push(1);
        alert(this.events.length);
    },

    say: function(words) {

    }
});

这样,每当一个类别开始形成一个新阵列(简称参考)时,就指定为<代码>events/code>。 我知道,我不是说谎,而是应该工作。
