An interesting implementation of the xplus download function.

The xplus client is automatically enabled when you click Download.ProgramTo download the book. I'm curious about its implementation method. So I saved the page and read itsCode. The javascript downloaded in it is found to be
Javascript: callclienttop ('downcentersingle. sulpx? Magid = 802 & amp; magname = katongwang0608 & amp; magtype = 0') then read the callclienttop function and find that clipboardData is used. setdata. it was originally written into the clipboard of the client. firefox also supports this feature. I found an article on the InternetArticle. Original link;: http://www.krikkit.net/howto_javascript_copy_clipboard.html

However, I think there is a security problem with this implementation method. If I accidentally have some sensitive information in the clipboard, then it is really insecure. At least I won't accept it.
