覆盖浏览器的键盘快捷键 [英] Overriding Browser's Keyboard Shortcuts

问题描述

我想通过截取文档对象的keypress事件处理程序而不是accesskey属性，在我的Web应用程序中添加对键盘快捷键的支持。

I'd like to add support for keyboard shortcuts to a couple of pages in my web application by intercepting the keypress event handler of the document object, not the accesskey attribute.

问题在于每个浏览器都有自己的键盘组合，所以不可能想出一套适用于所有网络浏览器且又一致的键盘组合。（例如，如果保存的快捷方式是愚蠢的话 Ctrl + Shift + S ，其中一个用于删除 Alt + D 。）

The problem is that every browser has its own keyboard combinations, so it's impossible to come up with a set of keyboard combinations that work on all web browsers and yet consistent.(e.g. It'd be silly if the shortcut for save was Ctrl + Shift + S while one for delete was Alt + D.)

所以我认为在我的几页中完全覆盖浏览器快捷方式会更简单。

So I figured it would be just simpler to override browser shortcuts altogether in a couple of pages with mine.

除了所有缺点，是否可能？如果是这样，你是怎么做到的？

All downside aside, is it possible? If so, how do you do it?

推荐答案

这里有一个很好的报道： http://unixpapa.com/js/key.html

There's an excellent coverage of this here: http://unixpapa.com/js/key.html

As对于是否应该这样做，stackoverflow的问题编辑器会覆盖相当多的键而不会中断太多（将鼠标悬停在工具栏按钮上）。

As for whether this is something that should be done, stackoverflow's question editor override's quite a few keys without disrupting too much (hover over the toolbar buttons).
