如何从 wpf 中的 Web 浏览器控件获取文档的标题 [英] How to get the Document's Title from a Web Browser control in wpf

问题描述

我在 TabControl 中创建了一个 Web 浏览器控件.我想将 TabItem 的标题设置为 Web 浏览器的文档标题.我在 WebBrowser 的 Navigated Event 中使用了以下代码

I have created a Web Browser control in a TabControl.I want to set the Header of the TabItem to the Document's title of the Web Browser. I used the following code in the Navigated Event of the WebBrowser

dynamic doc = tabBrowser.Document; //tabBrowser is the name of WebBrowser Control
tab.Header = doc.Title;            //tab is the name of the Tab Item

但是这段代码不能正常工作.标题仅针对少数站点更改.如何将 tabItem 的标题设置为文档的标题值?

But this piece of code doesn't work as it should.The header changes only for a few site. How can i set the Header of the tabItem to the Document's Title Value?

这是导航功能:

    public void tabBrowser_Navigated(object sender, System.Windows.Navigation.NavigationEventArgs e) 
    { 
       urlTextBox.Text = tabBrowser.Source.ToString(); 
       myHistory.addToHistory(tabBrowser.Source.ToString());
       BookMarks.addBookmark(tabBrowser.Source.ToString()); 
       dynamic doc = tabBrowser.Document; 
       tab.Header = doc.Title; 
    }

推荐答案

在我的代码中，我使用了 WebBrowser 的 LoadCompleted 事件.可能在您的导航事件文档中仍未准备好并且文档标题不正确或为空.

In my code I used LoadCompleted event of WebBrowser. Probably in your Navigated Event document still not ready and document title not right or empty.

private void MyWebBrowser_LoadCompleted_1(object sender, NavigationEventArgs e)
{
    try
    {
        MyTextBox.Text = MyWebBrowser.Source.ToString();
        Title_doc.Content = ((dynamic)MyWebBrowser.Document).Title;
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
}
