使用GM禁用页面的焦点检查功能

Question

我试图阻止页面停止自己，当它认为它失去了焦点。那么如何在使用GM的网页中禁用某个功能？

我会尝试通过给页面上的脚本，希望有人可以帮助我更好地解释它，哈哈。

<script>

现在我的一部分“认为”我想改变的是这个

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>'; 

我的想法是改变txnf varible将禁用此功能，如果页面心不是集中时停止计时。

这是我没有sucess尝试过的代码..

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

我得到错误控制台上没有错误，没有任何反应。

请谢谢！

通常，要通过手术禁用或更改页面的JavaScript，请使用checkForBadJavascripts，如"How to alter this javascript with Greasemonkey?"所示。

然而，在这种情况下，页面使用document.hasFocus()，所以它应该是不够的，只是劫持的是：因为你试图影响的JavaScript已经执行

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

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