问题描述
当任何访客首次打开我的网站时，我想弹出一个欢迎屏幕.
我在网站上有四个页面(主页，教程，活动，书籍).访客首次访问任何页面时，都应该获得欢迎"弹出窗口.访问任何页面后，导航到其他页面时都不会再次出现欢迎屏幕.
再次，当访问者重新访问该网站时，应重复该过程.
现在我的查询是:
1.如何建立这样的弹出窗口?
2.我可以使用javascript吗?但是如果禁用了javascript怎么办，还有其他类似ASP.NET的方法吗?
3.我可以选择通过javascript显示弹出窗口，但是如果禁用了javascript，则应该以其他方式显示弹出窗口???
I want to pop up a welcome screen when any visitor opens my website for the first time.
I''ve four pages (home, tutorials, events, books)in my website. The visitor should get the welcome pop up window, when he visits any of the page for the first time. After he visits any of the page, he should not get the welcome screen again when navigating to other pages.
Again when the visitor re-visits the website, the process should repeat.
Now my queries are:
1.How to do build such pop up window?
2.Can I do it with javascript? but what if javascript is disabled, what are the other ways to do this like ASP.NET?
3.Can I make such choice that the pop up window be shown via javascript but if javascript is disabled pop up window should be shown with the other way????
