javascript - JavaScript: Floating button to next page

Question

there is a site, not mine. I need a floating button, in the left side or whatever.

There are 3 questions:

1. How to make floating button in my browser?
2. And make this button load next page. exmpl: the url is localhost/dev/profile.php?uid=1. after click that button, the page will load localhost/dev/profile.php?uid=2 and subsequently. i wonder how to make uid value increase.

I use mozilla firefox and i noob.

Thanks. XD

对于浮动按钮，您可以尝试：http ://www.jtricks.com/javascript/navigation/floating.html 。

对于uid增加：

• 获取当前 URLdocument.URL
• 解析参数（在“？”之后）
• 得到号码parseInt
• 增加它
• 而不是将该参数分配给链接并访问它。
