var a = new xWin("1",460,400,200,200,"是要这个效果吗？","<br>这里有几点需要注意的地方：<br><br>1、xx这个变量是你自己添加的吧？想法是对的，但是放错了地方，你只在cls()这个方法里面给xx赋值，这就造成了这个对象在窗口第一次出现时由于没有被赋值(关闭按钮还没有被点击)，导致无法获取，所以应该把对xx赋值这个工作放在窗口第一次初始化完成的地方，也就是xWin函数中，this.build语句之后。当然也可能你已经试过放在这里，但是发现根本不起作用，这就涉及到下一个要注意的问题了。<br><br>2、Build函数的最后，你是通过insertAdjacentHTML()方法把生成的代码放在了网页全部html标签之后，因此生成的代码中的对象在页面中使用getElementById()方法根本访问不到，所以才会不起作用，怎么改呢？方法很多，我是这样处理的，在页面body的关闭标签之前插入一个div，然后用innerHTML()方法写入。<br><br>3、对于代码，我进行了一点修正，因为发现你的cls()方法当中把xWin和他的阴影一并隐藏了，但是在ShowHide()方法中却只把xWin显示出来，这就导致关闭(实质上是hidden)后再打开的窗体已经没有了阴影，当然这也不算什么大问题，我在xWin和他的阴影外面套了一个allx的div，再把这个对象赋给xx，然后就可以一并隐藏一并显示了，更方便一些。<br><br>4、主要就是这几个地方，这个效果还是很不错的，不过程序结构还可以再优化一些，代码比较多，我也没有细看，稍微改了一下，可能不是最好的方法。大家继续提建议啊。希望对楼主能有帮助。");
