问题 Trying to detect if new elements are added or removed from the DOM in MSHTML. Is there such event that will fire? http://msdn.microsoft.com/en-us/library/aa741877(v=VS.85).aspx In IE9 there is IDOMMutationEvent::initMutationEvent http://msdn.microsoft.com/en-us/library/ff975905(v=vs.85).aspx 回答1: Yes, it is possible now in IE8, though it is not part of the MSHTML event structure, but Accessibility. Trigger (EVENT_OBJECT_REORDER) is new in IE8 - See http://blogs.msdn.com/b/ie/archive/2008/12

Why is the Webbrowser control DocumentComplete event fired for top level frame first?

阅读更多关于 Why is the Webbrowser control DocumentComplete event fired for top level frame first?

Based on this article on MSDN: How To Determine When a Page Is Done Loading in WebBrowser Control , and from past discussions on StackOverflow, I would assume that in case of a document with multiple frames, the DocumentComplete event would fire multiple times, and the last time would be for the top level frame. However, using the exact sample code from the above-mentioned MSDN link, I find that if there are multiple DocumentComplete events when doing a Navigate to a URL, the condition is satisfied in the following code the first time, not the last time as the article seems to indicate.

阅读更多关于 Call JavaScript function from .NET Compact Framework in WebBrowser control

Is there anyway to call a JavaScript function from .NET Compact Framework through the WebBrowser control? It works with the Navigate() Method. I just tried it with the Windows Mobile 5.0 Pocket PC Emulator. For example: webBrowser1.DocumentText = @"<html><head> <script type='text/javascript'> function doIt() { alert('hello again'); return 'i did it!'; } </script> </head><body>hello!</body></html>"; webBrowser1.Navigate(new Uri("javascript:doIt()")); 来源： https://stackoverflow.com/questions/3135586/call-javascript-function-from-net-compact-framework-in-webbrowser-control

Save WebBrowser Control Content to HTML

阅读更多关于 Save WebBrowser Control Content to HTML

I have a WebBrowser Control and have called the Navigate(url) function of it for a given file. Then I have manipulated the DOM tree by giving new Id's to some of the tags. Now I want to save the result in an HTML file. I have tried to use the webBrowser.DocumentStream, but it seems that this stream won't change after manipulating the DOM tree. Please keep in mind that the encoding in WebBrowser.Document.Encoding must be used to encode the result. Like this: File.WriteAllText(path, browser.Document.Body.Parent.OuterHtml, Encoding.GetEncoding(browser.Document.Encoding)); 来源： https:/

Gecko API for DOM

阅读更多关于 Gecko API for DOM

Does Gecko expose an API for working directly with its DOM? I'm looking for a class like HtmlElement that can be used to build/traverse trees of HTML content. I'm trying to host Gecko as a web browser control in a desktop application, and would prefer a direct API rather than going through COM. Thanks! Yes, virtually all of the classes relating to the DOM are exposed through XPCOM . In fact, I believe the entire functionality of Gecko is exposed this way. greyfade: whilst your answer is technically correct, i've found that the gecko DOM API is incredibly hard to find, because of all the
