如何识别Internet Explorer中的最后一个ondocumentcomplete？ [英] How to identify last ondocumentcomplete in Internet Explorer?

问题描述

我在C Sharp中开发一个IE工具栏，可以访问IE中显示的html源页面并进行处理。我依赖于ondocumentcomplete事件处理程序。触发时，会获取html源代码。但是我的页面有框架有问题，因为ondocumentcomplete是针对每个帧触发的，最后一个是外框，窗口。为了解决这个问题，我确实喜欢这个 -

Hi,
I am developing an IE toolbar in C Sharp that accesses the html source of page displayed in IE and process it. I'm relying on the ondocumentcomplete event handler. When it is fired, the html source is taken. But I have a trouble with pages having frames since ondocumentcomplete is fired for each frame, the last being the outer frame, the window. In order to tackle this I did like this -

public void OnDocumentComplete(object pDisp, ref object URL)
{
  if (pDisp.Equals(Explorer.IWebBrowser_Parent))
    {
         // check for frames n get the source of all
    }
  else
        // ignore
 }

像这样，我能够获得最后一个ondocumentcomplete事件，然后获取所有帧的来源。但问题是对于某些具有框架或iframe的页面，不会为窗口触发ondocumentcomplete。因此上述代码不会处理任何此类代码，例如 - http://www.w3schools.com/html/tryit .asp？filename = tryhtml_intro [ ^ ]触发该URL的ondocumplete，但是点击编辑并单击我按钮虽然重新加载了框架，但没有触发ondocumentcomplete为窗口。如何解决这个问题？



谢谢，

Arun

Like this I was able to get the last ondocumentcomplete event and then get the source of all the frames. But the problem is for certain pages that have frame or iframe, ondocumentcomplete is not fired for the window. so the above code would not process any such e.g - http://www.w3schools.com/html/tryit.asp?filename=tryhtml_intro[^] fires an ondocumplete for that url, however clicking on 'edit and click me' button though reloads the frame, doesnt fire ondocumentcomplete for the window. How to work around this?

Thanks,
Arun

感谢Nijboer的回应。我得到了解决方案。它在 http://support.microsoft.com/kb/q180366/ [ ^ ]



问我们比较第一个navigationcomplete2触发的每个文档完成。

Thanks for the response Nijboer. I got the solution. Its mentioned clearly in http://support.microsoft.com/kb/q180366/[^]

Asks us to compare the first navigatecomplete2 fired with each documentcomplete.
