原标题:Safari extension running injected javascript multiple times
最佳回答

你不谈你们的履行,但你的法典可能是问题。 关键是了解注入文字的装载量。 http://developer.apple.com/library/content/documentation/Tools/Conceptual/SafariExtensionGuide/Injecting texts/Injecting textss.html

文本放入顶级网页,任何有超文本来源的儿童,如斜线。 不能假设只有一例是您的书状。

问题回答

文件提到,你可以使用活动处理器在三个不同级别发出信息:

safari.application.activeBrowserWindow.activeTab.addEventListener("message", waitForMessage, false);

safari.application.activeBrowserWindow.addEventListener("message", waitForMessage, false);

safari.application.addEventListener("message", waitForMessage, false);

但你们应该选择其中之一。 你们有没有把活动听众附在你们所有三个方面? 如果是的话,你肯定会花三倍的时间。
