Question

我想为点击活动的弹出窗口编写扩展。 我现在用这个代码：

window.onclick=null;
document.onclick=null;
window.onmousedown=null;
document.onmousedown=null;
window.onmouseup=null;
document.onmouseup=null;

它适用于某些网站，但其他网站使用此代码：

 if (!document.addEventListener) 
    document.attachEvent('onclick',somefunction,false);
else
    document.addEventListener('click',somefunction,false);

还在工作。

我知道这样的代码：

var el = document.getElementById('el-id'),
elClone = el.cloneNode(true);
el.parentNode.replaceChild(elClone, el);

不要复制监听器，但我想删除文件监听器。

编辑： popups.js样本，点击时打开弹出窗口：
