Question

在Windows窗体应用程序中使用以下代码在Web浏览器中滚动页面：

 HtmlDocument doc = webBrowser.Document;
 mshtml.IHTMLDocument2 htmldoc = (mshtml.IHTMLDocument2)doc.DomDocument;
 htmldoc.parentWindow.scrollBy(265, 20);

有没有人知道如何在WPF应用程序中执行相同操作（不使用WindowsFormsHost）？

Answer 1

如果您正在使用System.Windows.Controls.WebBrowser课程，请查看Document媒体资源。您应该能够将其强制转换为mshtml.HTMLDocument或mshtml.IHTMLDocument2和代码

mshtml.HTMLDocument htmlDoc = webBrowser.Document as mshtml.HTMLDocument;
if (htmlDoc != null) htmlDoc.parentWindow.scrollBy(265, 20);

应该适合你。

希望这有帮助，尊重

Answer 2

你应该轻松地做到：

    private void WebBrowser_LoadCompleted(object sender, System.Windows.Navigation.NavigationEventArgs e)
    {

        ((WebBrowser)sender).InvokeScript("eval", "$( document ).scrollTop( 1700 );");
    }

Answer 3

Javascript：

的window.onload = toBottom;

function toBottom（）{alert（＆＃34;滚动到底部......＆＃34;）;   window.scrollTo（0，document.body.scrollHeight）; }

HTML：

> <html>
>     <head>
>         <script src="testme.js" language="javascript" type="text/javascript"></script>
>     </head>
>     <body>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>
>         Some big text<br>           
>     </body>
> </html>
