我有一个名为webBrowser3的webBrowser，它显示指向HTML文件内容的链接。示例：-一个WebBrowser（webBrowser3）显示目录（TOC），我希望在我单击的任何章节或其部分上，它在另一个WebBrowser（webBrowser2）上显示其内容，该WebBrowser以webBrowser3的相同形式放置。我制作了目录（TOC），但当点击任何章节时，它会在放置TOC的同一个webBrowser（webBrowser3）上显示其内容。我用下面的方法试过，但没有达到预期的效果

  string toc = File.ReadAllText(StaticClass.ZipFilePath + "\\OEBPS\\IDSBooktoc.html");

         webBrowser3.DocumentText =toc;

我没有得到确切的我应该做什么，以做到这一点。。。这是我的HTML

这是我表单的完整代码，我使用了私有变量“nexturl”，因为当我单击webbrowser3上的链接时，webbrowser2似乎没有检测到url已更改（链接相同，仅更改书签）

我的代码和您的代码的区别在于，您不使用url加载页面，而是直接在webbrowser2和webbrowser3中设置html

试着这样做：

private string tocpage = "IDSBooktoc.html";
private string outpage = "IDSBookout.html";

private void Form1_Load(object sender, EventArgs e)
{
    webBrowser3.DocumentText = File.ReadAllText(tocpage);
    webBrowser2.DocumentText = File.ReadAllText(outpage);

    webBrowser3.Navigating += new WebBrowserNavigatingEventHandler(webBrowser3_Navigating);
}

private void webBrowser3_Navigating(object sender, WebBrowserNavigatingEventArgs e)
{
    e.Cancel = true;

    //scroll webbrowser2
    string bookmark = e.Url.Fragment.Replace("#", "");
    webBrowser2.Document.GetElementById(bookmark).ScrollIntoView(true);
}

在我的代码中，不会调用事件导航方法。在发布代码之前，我已在电脑上尝试过该代码。你能提供一个html文件吗？如果你调试这个项目，会调用webBrowser3\u DocumentCompleted事件？我已经添加了我的html。我希望你能得到我想要的。。在这个html中，我有一些指向另一个html文件的链接。我把它放在webBrowser3中，如果我点击这个HTML文件中的任何链接，我想在webBrowser2中打开它的内容。这两个浏览器都放在一张表格上我还有一个问题。。如果不是webbrowser3，我使用treeview，那么它也会工作吗？如果我使用treeview，那么为了从treeview导航到webbrowser，我应该触发哪个事件？尝试AfterSelect事件你能为treeview编写代码吗？我面临一些问题，我的节点在treeview中出现了两次。示例：-我的树状视图的结构是-引言1-传统产品开发和验证过程-引言1-传统产品开发和验证过程，但它应该类似于-引言1-删除时的传统产品开发和验证过程“webBrowser2.DocumentCompleted+=新的WebBrowserDocumentCompletedEventHandler（webBrowser2\u DocumentCompleted）；“那么我的问题就解决了。但我不明白为什么我们要用代码写这行。你能解释一下这行代码的用法吗？我写这行代码是因为我首先使用webbrowser2解析toc文件。在我的代码中，我：1）读取html文件2）ondocumentcompleted事件填充treeview 3）detach事件，因为我不需要它。也许你在另一个事件中解析你的html？非常感谢你的帮助。事实上，这是我的错误，我自己在触发此事件之前没有清除节点。

private string tocpage = "IDSBooktoc.html";
private string outpage = "IDSBookout.html";

private void Form1_Load(object sender, EventArgs e)
{
    webBrowser3.DocumentText = File.ReadAllText(tocpage);
    webBrowser2.DocumentText = File.ReadAllText(outpage);

    webBrowser3.Navigating += new WebBrowserNavigatingEventHandler(webBrowser3_Navigating);
}

private void webBrowser3_Navigating(object sender, WebBrowserNavigatingEventArgs e)
{
    e.Cancel = true;

    //scroll webbrowser2
    string bookmark = e.Url.Fragment.Replace("#", "");
    webBrowser2.Document.GetElementById(bookmark).ScrollIntoView(true);
}

private string tocpage = "IDSBooktoc.html";
private string outpage = "IDSBookout.html";

private void Form1_Load(object sender, EventArgs e)
{
    //load toc, only for parsing
    webBrowser2.Visible = false;
    webBrowser2.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(webBrowser2_DocumentCompleted);
    webBrowser2.DocumentText = File.ReadAllText(tocpage);
}

void webBrowser2_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
    //Populate treeview
    foreach (HtmlElement ele in webBrowser2.Document.GetElementsByTagName("a"))
    {
        treeView1.Nodes.Add(ele.GetAttribute("href"), ele.InnerText);
    }
    //detach event
    webBrowser2.DocumentCompleted -= new WebBrowserDocumentCompletedEventHandler(webBrowser2_DocumentCompleted);
    //change webbrowser2 source
    webBrowser2.DocumentText = File.ReadAllText(outpage);
}

private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
{
    string selected = e.Node.Name; //IDSBookout.html#NCXGen0
    string bookmark = selected.Substring(selected.IndexOf("#") + 1);
    webBrowser2.Document.GetElementById(bookmark).ScrollIntoView(true);
    webBrowser2.Visible = true;
