论坛常用js，IE7不支持Ctrl+Enter回贴的解决办法
添加日期：2006-11-23 9:17:28     [大 中 小]

前些日子有人发现IE7对Ctrl+Enter不支持。
分析了一下，原来是IE7去掉了对原来Javascript中ctrlKey、shiftKey、和altKey的支持。
没办法只好换成原来的键值了。

说说IE7的这个修正，
其实ctrlKey、shiftKey、和altKey本身也是对键值的判断，只不过是集成在JS里面了。
这样开发者也不用多记代码了，执行起来也不用多转个弯子了。

以动网的DVBBS7修改作范例，具体自己对比研究：

DhtmlEdit.js
