使用GM禁用页面的焦点检查功能 [英] Disabling a page's focus-checking function using GM

问题描述

当它认为页面失去焦点时，我正试图阻止该页面停止运行.那么如何使用GM禁用网页中的功能?

I'm trying to stop a page from stopping itself when it thinks it's lost focus. So How do I disabling a function within webpage using GM?

我将通过在页面上提供脚本来尝试，希望有人可以帮助我更好地对其进行解密，大声笑.

I'll try by giving the script on the page, hopefully someone can help me decipher it better, LOL.

<script>

现在我想改变的部分就是这个

Now the part I 'think' I want to change is this

txnf='<span style=cursor:pointer>You need to keep this advert<br />on focus to get credit<br /><a href=javascript:void(0); style=font-size:13px>Please click here to continue<\/a><\/span>';

我的想法是，如果页面没有被关注，那么更改txnf变量将禁用此功能，该功能将停止计时器.

My thinking is that changing the txnf varible will disable this function that stops a timer if the page isnt focused upon.

这是我没有成功尝试过的代码.

Here's the code I tried with no sucess..

document.head.innerHTML= document.head.innerHTML.replace('txnf','');

我在错误控制台上没有收到任何错误，什么也没发生.

I get no error on error console and nothing happens.

请谢谢！

推荐答案

通常，要通过外科手术方式禁用或更改页面的javascript，请使用checkForBadJavascripts，如.

In general, to surgically disable or alter a page's javascript, use checkForBadJavascripts as shown in "How to alter this javascript with Greasemonkey?".

但是，在这种情况下，页面使用的是document.hasFocus()，因此只要劫持该页面就足够了:

However, in this case, the page is using document.hasFocus(), so it should be enough to just hijack that:

// ==UserScript==
// @name     _YOUR_SCRIPT_NAME
// @include  http://YOUR_SERVER.COM/YOUR_PATH/*
// @run-at   document-start
// @grant    none
// ==/UserScript==

document.hasFocus = function () {return true;};
