C#中ihtmldocument2怎么获取页面内容

Answer 1

1.获取frame的document
HtmlDocument htmlDoc = webBrowser1.Document;
htmlDoc = webBrowser1.Document.Window.Frames["frmRpt"].Document;
"frmRpt"为iframe的name；
2.获取frame的源文件
MessageBox.Show(webBrowser1.Document.Window.Frames["main"].Document.Body.InnerHtml);
3.获取frame的HTMLDocument接口
HTMLDocument doc = (HTMLDocument)webBrowser1.Document.DomDocument;
object j;
for (int i = 0; i < doc.parentWindow.frames.length; i++)
{
j = i;
HTMLWindow2Class frame = doc.parentWindow.frames.item(ref j) as HTMLWindow2Class;
if (frame.name == "main")
{
MessageBox.Show(frame.document.title);
}
}
4.获取frame的IHTMLDocument2接口
IHTMLDocument2 doc = (IHTMLDocument2)webBrowser1.Document.Window.Frames["main"].Document.DomDocument;
5.取得frame中被点击的连接
private void webBrowser1_Navigating(object sender, WebBrowserNavigatingEventArgs e)
{
string url = webBrowser1.Document.Window.Frames["main"].Document.ActiveElement.GetAttribute("src");
}
