在 DHTML/AJAX 页面的情况下，如何使用浏览器帮助程序对象 (BHO) 获取完整的 HTML 正文? [英] How to get complete HTML body using browser helper object (BHO) in case of DHTML/AJAX page?
问题描述
我正在编写一个 BHO，它分析从 'DWebBrowserEvents2' 的 'onDocumentComplete' 事件中获取的 HTML.目前它工作正常，除非我有一个 DHTML/AJAX 页面，其中 HTML 句柄交付过早.
I'm writing a BHO that analyze the HTML taken from the 'onDocumentComplete' event of 'DWebBrowserEvents2'. Currently it works fine, unless I have a DHTML/AJAX page, where HTML handle is delivered too soon.
作为示例，我尝试在 'http://www.google.com' 上使用它.从 'onDocumentComplete' 事件中，我可以获得大部分页面，但在最顶部的链接/锚点中，地图、视频、orkut 等的 'href' 不可用(通常是 javascript:void(0)).
For sample, I tried using it on 'http://www.google.com'. From the 'onDocumentComplete' event I can get most of the page but in the topmost link/anchors, the 'href' for maps, videos, orkut etc. is not available (normally it is javascript:void(0)).
有没有人知道如何在页面完全加载而不是仅在框架/正文加载时捕获它?
Has anyone any ideas how to capture it when the page is fully loaded rather than just when the frame/body is loaded?
谢谢，

推荐答案
AJAX DHTML 更改大多不会导致进一步的 onDocumentComplete 调用.
The AJAX DHTML changes mostly don't cause a further onDocumentComplete call.
您需要注册更多的窗口或文档事件，例如 DISPID_HTMLWINDOWEVENTS2_ONLOAD.
You need to register for further Window or Document events such as DISPID_HTMLWINDOWEVENTS2_ONLOAD.
一种方法是建议您使用通用事件接收器接口提供的 com 对象的窗口.hr = AtlAdvise(winDisp, pWinHandler, DIID_HTMLWindowEvents2, &dwCookie);
One method is to advise the window of a com object that you provide with the generic event sink interface.
hr = AtlAdvise(winDisp, pWinHandler, DIID_HTMLWindowEvents2, &dwCookie);
当这个进一步的事件被触发重新检查文档时，你会发现它被更新了.
When this further event is triggered re examining the document you will find that it is updated.
