在我的IE BHO中,我使用:
创建一个输入按钮元素 var button = doc.createElement("input");
button.setAttribute("value", "myButton"); //next line gets an error
button.addEventListener("click", openFunction, false); //openFunction is a function inside of the same class
当我尝试调用button.addEventListener时,我得到'mshtml.IHTMLElement'不包含'addEventListener'错误的定义。我发现这很奇怪,因为根据这个网站(http://help.dottoro.com/ljeuqqoq.php)我应该清楚。
我也看到了this线程,但是对于我正在尝试做的事情似乎有些过分,我无法让它发挥作用。

终于开始工作了。不得不使用类似于我在原始问题中链接的线程的方法。
/// Inside the BHO.cs file and in my namespace
/// Generic HTML DOM Event method handler.
///
public delegate void DHTMLEvent(IHTMLEventObj e);
///
/// Generic Event handler for HTML DOM objects.
/// Handles a basic event object which receives an IHTMLEventObj which
/// applies to all document events raised.
///
public class DHTMLEventHandler
{
public DHTMLEvent Handler;
HTMLDocument Document;
public DHTMLEventHandler(HTMLDocument doc)
{
this.Document = doc;
}
[DispId(0)]
public void Call()
{
Handler(Document.parentWindow.@event);
}
}
public void BrowserEventHandler(IHTMLEventObj e)
{
try
{
if (e.type == "click" && e.srcElement.id == "IDOfmyButton")
{
// do something.
something();
}
}
catch
{
}
}
在我的OnDocumentComplete方法中(也在上面相同的命名空间中[新手的额外信息]):
DHTMLEventHandler myHandler = new DHTMLEventHandler(framedoc);
myHandler.Handler += new DHTMLEvent(this.BrowserEventHandler);
button.onclick = myHandler;
很多工作只是为了点击按钮。在Firefox中它是一行:O
