在写一个项目时要用到广告模块,为了不想用ASP生成脚本代码时较麻烦,于是产生了写脚本类的念头,即是用一个类模块的脚本代码去控制所有在同一页面显示的漂浮广告。但在写的过程中发现JS脚本竟然在setTimeout里不能使用类的方法。奇怪,是不是我弄错了还是JS脚本就不能这样??但VBS脚本就可以!我晕…… 不说了,贴代码: [JS脚本] 示例代码(包括两种脚本的使用): <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML> <HEAD> <TITLE> 漂浮广告显示脚本类演示 </TITLE> </HEAD> <BODY> |
