所以我试图弄清楚如何为运行并导航到各个页面的greasemonkey扩展创建一个切换按钮。
所以这就是我到目前为止的作品
var keepgoing = true
if语句和内容的开头
else if keepgoing == true
{ newsearch(); }
按钮点击:
if keepgoing == true { keepgoing = false }
else if keepgoing == false { keepgoing = true }
所以基本上我需要帮助在网页上放一个按钮。 并且它需要在浏览页面时记住var。
谢谢,Ray

如果您想要持久性按钮(或任何数据),则需要使用某种存储。如果涉及多个域,请使用GM_setValue()。如果所有内容都在同一个域中,请使用localStorage。
我自己添加了这种持久性按钮,这是一个简单的向下脚本,显示我使用的内容。它不只是添加一个按钮,它使按钮UI更加用户友好,IMO。
