这个其实跟你提供的只改了 #msg_win 的样式 left:0; 以前是 right:0
追问
不是把right改成left，而是保持右下的弹出框，再增加一个左侧的，请问如何去做？谢谢！

改变当中让丛余的样郑塌式即可.
#msg_win{border:1px solid
#A67901;background:#EAEAEA;width:300px;position:absolute;right:0;font-size:12px;font-family:Arial;margin:0px;display:none;overflow:hidden;z-index:99;}
这坦滚里改成
#msg_win{border:1px solid
#A67901;background:#EAEAEA;width:300px;position:absolute;left:0;font-size:12px;font-family:Arial;margin:0px;display:none;overflow:hidden;z-index:99;}
这就从右下角跑到左下角了.

您好，不是把原来右侧改成左侧，而是在这个基础上加一个左侧的弹出框，保持右侧不变
追答
这个js没办法使用两次. 因为原生的window.onstroll事件你只能绑定一次.你多次绑定它只认最后一次的事件..除非将他的window.onstroll事件还有window.onreise事件都再写一遍逻辑.
另外.现在的网页最好不要有太多的框框弹出来,不管是哪个位置的.这样的框框对用户来说都不会太喜欢.
