如何FireFox下实现IE的showModalDialog的功能?
找遍了网络上的文章都是说设置一下 'modal=yes '   就可以,例如: 
 window.open( 'openwin.html ', 'newWin ', 'modal=yes,width=200,height=200,resizable=no,scrollbars=no ');      
 实际上我在firefox   最新版本   2.0.0.6   上试过n遍,它只是打开一个窗口,窗口是可以随便切换的!!!   根本实现不了ie的showModalDialog的功能.      
 请大家使用firefox2.006版本,测试一下,或者给个解决方案,谢谢!   
 有些朋友说可以,请注明一下你的firefox版本,谢谢!
------解决方案--------------------用var win = window.showModalDialog()不行吗?呵呵。
------解决方案--------------------可以用css模拟,网上很多
------解决方案--------------------通过DIV模拟模态,代码
