任何人都可以帮助我覆盖浏览器的 CTRL+F 并将其替换为 Silverlight 自定义搜索。我想我们可以用 JavaScript 来处理这种情况。
您可以尝试这个，来替换查找功能：
window.addEventListener("keypress",function (event) { /* Add keydown too */
if ((event.keyCode == 114) || (event.ctrlKey && event.keyCode == 70)) {
// Block CTRL + F event
event.preventDefault();
}
})
我在我的网站上为此创建了一个键盘快捷键，我还创建了这个JSFiddle，其中包含脚本以及本文下面的工作演示！该演示与小提琴中的完全相同！另外，作为参考，我的网站网址的来源（如代码片段中所示）是此链接 顺便说一句，我的另一篇堆栈溢出文章与这篇文章非常不同，是 this URL 而 Shortcut.js 小提琴是 this
<h1> Click In This Box and press ctrl+F </h1>
<a href https://antimalwareprogram.co/view-source:antimalwareprogram.co-pages_php.source-javascript_page.js tagret=blank>Click to see my site source if this fiddle is broken!</a> <p>

Then Scroll down to the bottom then scroll up, or do ctrl+F there and inser this line: https://antimalwareprogram.co/shortcuts.js<h1>

that and everything below it is part of my keyboard shortcuts</h4>

<script src="https://antimalwareprogram.co/shortcuts.js"> </script> <!-- Or Just open that script page and ctrl+A Then Ctrl+C and past it into your own site and change url to /filename.js -must save it as a .js extension! This script searches my site! To make it search your just change down below where it says ---
document.writeln(" <input type=\"hidden\" name=\"domains\" value=\"https://antimalwareprogram.co\" checked=\"checked\"> ");
document.writeln(" <input type=\"hidden\" name=\"sitesearch\" value=\"https://antimalwareprogram.co\" checked=\"checked\"> ");
Just change the https://antimalwareprogram.co on both lines to https://yoursite or http://yoursite make sure not to remove the other slashes around it though or the script wont work, also this wont work if you have a script blocker blocker , so you can have a html meta no script redirect tag but nothing else will work if its not that meta tag for noscript! -->

</script>对兰迪尔的回答做一点补充 （抱歉我无法添加评论） 如果 keypress 不适合您，您可以尝试使用事件 keydown 而不是 keypress。 它对我有用。
