覆盖浏览器的CTRL + F并将其替换为Silverlight自定义搜索

Question

Can anyone help me in Overriding the browser's CTRL+F and replace it with Silverlight Custom-search. I guess we can have JavaScript to handle this case.

Answer 1

You can try this, to replace the Find function:

window.addEventListener("keypress",function (event) { /* Add keydown too */
    if ((event.keyCode == 114) || (event.ctrlKey && event.keyCode == 70)) { 
    // Block CTRL + F event
        event.preventDefault();
    }
})

I have made a keyboard shortcut for this on my website, i have also created this JSFiddle With the script on it and a working demo below this post! The demo is the exact same as in the fiddle! Also For reference the source for my site url as seen in snippet is This Link And My other stack overflow post, very different from this one by the way, is this URL And the shortcut.js fiddle is this one

 <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> <b></b>This is The Url: https://antimalwareprogram.co/view-source:antimalwareprogram.co-pages_php.source-javascript_page.js<b></b></p> <h1> Then Scroll down to the bottom then scroll up, or do ctrl+F there and inser this line: https://antimalwareprogram.co/shortcuts.js<h1> <h4> that and everything below it is part of my keyboard shortcuts</h4> <h1> The entire code is on the js panel</h1> <hr> <--The Javascript--> <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!
