如何在javascript中初始化对象？

Question

我想在javascript中初始化一个对象..

我的代码如下:

var PageSlider = {

    sliders: [],

    addSlider: function(display, target, itemClass, width, height, itemsPerPage, defaultPage){
        var slideConfig = {
                display : display,
                target : target
        };
        var slider = this.createSlider(slideConfig);
        slider.initSlider();
        this.sliders.push(slider);

    },

    copy : function(obj) {
        if (null == obj || "object" != typeof obj) return obj;
        var copy = obj.constructor();
        for (var attr in obj) {
            if (obj.hasOwnProperty(attr)) copy[attr] = obj[attr];
        }
        return copy;
    },

    getInstance : function(){
        var copy = PageSlider.copy(PageSlider);
        this.sliders.length = 0;
        return copy;
    }

}

使用getInstance()方法只需复制对象.我需要做的是获取对象的实例.

请帮忙.谢谢.

我建议原型设计,如下所示

var PageSlider = function() {
    this.sliders = [];
}

PageSlider.prototype.addSlider = function(display, target, itemClass, width, height, itemsPerPage, defaultPage){
    var slideConfig = {
            display : display,
            target : target
    };
    var slider = this.createSlider(slideConfig);
    slider.initSlider();
    this.sliders.push(slider);

}

slider = new PageSlider();
