也没看到啊.而且我主要想要实现它的那个效果,谁来解答下啊
分不够再加,加分要24小时后,我在线等,希望大家帮帮
FF有,你等页面完全加载完后再关..我的FF3.5.1有这个效果

onbeforeunload 是一个事件的触发入口.
触发对象是已经注册好的上面那些事件.注:onbeforeunload并不是事件,只是个指向监听器的句柄而已.
首先监听到有响应onbeforeunload的事件时候就去执行regularChatDisplay方法
这里showChat是一个创建蒙板并输出div窗口的方法
以后的看着弄吧
太感谢你哒.zowell,也谢谢其他所有回帖帮助的,我现在去做,要是有困难还会回来问的.分空2天加到300再给.谢谢谢各位.特别感谢!
