@@@@@用DIV仿制模式对话框的问题@@@@@
我用javascript创建了一个类似模式对话框的div, 在IE7,和 FireFox下，原页面的控件都能被覆盖，无法使用.直到该DIV删除后才可使用.
但是在IE6中，div只能覆盖文本字体和 disabled的控件，普通控件仍然能使用请问这个是什么原因，
如何解决。

起初我以为是我的div中动态创建的控件的问题，后来发现，纯粹创建div也是这样.
谢谢

你弄个半透明的DIV把下面页面全遮盖住不就可以了？

<div id= "id2 ">
这里可以放内容，或者添加div用innerhtml进行添加内容就可以了
<br/> <input name= "Button1 " type= "button " value= "button " onclick= "hide() "/>
</div>
<div id= "id1 "> 123 </div>

<form method= "post ">
