我正在尝试修改我的GreaseMonkey脚本,从window.onload触发到window.DOMContentLoaded,但此事件永远不会触发。
我正在使用FireFox 2.0.0.16 / GreaseMonkey 0.8.20080609
This是我正在尝试修改的完整脚本,正在更改:
window.addEventListener ("load", doStuff, false);
到
window.addEventListener ("DOMContentLoaded", doStuff, false);

所以我用Google搜索了greasemonkey dom ready,而first result似乎说的是,paintmonkey脚本实际上是在“DOM ready”运行,所以你只需要删除onload调用并立即运行脚本。 / p>
我删除了 window.addEventListener ("load", function() {
和 }, false);
包装,它完美无缺。通过这种方式多响应更快,页面会立即显示,并且您的脚本会应用到该页面,所有未见的问题都会突出显示,根本不会闪烁。并且非常高兴......是的。

GreaseMonkey脚本本身是在DOMContentLoaded上执行的,因此不需要添加一个load事件处理程序 - 只需让你的脚本立即执行它需要的任何操作。
