我爱Prototype,但它没有附带任何小部件。特别是,它没有为窗口/对话框创建提供任何内容。
我尝试了Prototype Window附加库,但发现它不可靠,并且很长时间没有维护。
任何人都有任何推荐的解决方案?或者从第一原则创建对话的任何配方/模式(即没有Prototype以外的库)?我需要模态行为(具有褪色的背景效果),我必须支持IE6以及现代浏览器。
为了清楚起见,我不打算退出原型,我真的不想包含额外的基础库,如JQuery。

对于一个非常简单的对话框,请查看以下代码:http://snippets.dzone.com/posts/show/3411
非常简单 - 只是我想要的。
代码经过了一些修改。这是适用于我的最终版本:

Scriptaculous是一个基于Prototype构建的UI / Widget /特效库。你一定会找到你想要的东西。
