如何使用GreaseMonkey为浏览器返回“/”键？ [英] How can I use GreaseMonkey to give the browser back the "/" key?
问题描述
很多网页似乎都使用 / 键进行搜索。我想禁用它，因为100％的时间我想用 / 在FireFox的页面中搜索。有没有办法可以用GreaseMonkey或dotjs覆盖这种行为？
Lots of web pages seem to use the / key for searching. I'd like to disable that because 100% of the time I want to use / to search in the page in FireFox. Is there a way I can override this behavior with GreaseMonkey or dotjs?

如果您设置
窗口上的addEventListener（）If you set
addEventListener()Doc onwindowand use "event capture", you will catch 99% of what the page tries to do. (Not counting plugins like Flash)您无法确定页面是否触发
keydown，keyup，keypress，或某些组合，因此拦截keydown（使用的典型事件）和keyup。但是，如果页面触发keypress，则阻止该事件可能需要这一种技术。这是因为< body>上的keypress事件会触发Firefox的页内搜索，但是没有办法（重新）从javascript触发搜索（为了安全）。You can't be sure if the page fires off of
keydown,keyup,keypress, or some combination, so interceptkeydown(the typical event used) andkeyup. But, if the page fires off ofkeypress, then blocking the event may require this kind of technique. This is because thekeypressevent, on<body>, bubbles up to trigger Firefox's in-page search, but there is no way to (re)trigger that search from javascript (for security).幸运的是，您的两个示例网站不需要任何严厉的措施。
Fortunately, your two sample sites do not require any drastic measures.
事件常数，如
DOM_VK_SLASH很棒，但它们仍然只是Firefox版本。从这个问题的标签（dotjs）来看，目前还不清楚你是否也想在Chrome上工作。Event constants, like
DOM_VK_SLASHare great, but they are still pretty much Firefox-only. From this question's tags (dotjs), it is not clear if you mean for this to work on Chrome, too.总而言之，这个完整的脚本有效：
Putting it all together, this complete script works:
// ==UserScript== // @name _Nuke the forward slash on select pages // @include https://github.com/* // @include https://wiki.jenkins-ci.org/* // @grant GM_addStyle // ==/UserScript== /*- The @grant directive is needed to work around a design change introduced in GM 1.0. It restores the sandbox. */ //-- "true" tells the listener to use capture mode. window.addEventListener ('keydown', blockSlashKey, true); window.addEventListener ('keyup', blockSlashKey, true); /*-- Don't block keypress on window or body, this blocks the default page-search, too. window.addEventListener ('keypress', blockSlashKey, true); */ function blockSlashKey (zEvent) { var FORWARD_SLASH = 191; // For keydown and keyup var ASCII_SLASH = 47; // For keypress if ( zEvent.which === FORWARD_SLASH || (zEvent.which === ASCII_SLASH && zEvent.type == "keypress") ) { zEvent.stopPropagation(); } }
注意：此脚本似乎适用于您列出的两个网站，包括Chrome和Firefox。并且，它不会停止将 / 键入输入或textareas。但是，它很可能会导致某些网站无法在 / 键上触发其他事件。
Note: This script seems to work well on the two sites you listed, in both Chrome and Firefox. And, it will not stop the typing of / into inputs or textareas. But, there is a tiny chance that it might cause some sites to not fire other events on the / key.
如果发生这种情况，请使用
zEvent.target.nodeName ==BODY等检查来限制blockSlashKey（）的操作。If that happens, then use checks like
zEvent.target.nodeName == "BODY"to restrictblockSlashKey()'s operation.这篇关于如何使用GreaseMonkey为浏览器返回“/”键？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
