处理硬件后退按钮，并把它发送到WebBrowser控件在Windows Phone上运行 [英] Handling hardware back button and sending it to WebBrowser control running on Windows Phone

问题描述

我有嵌入PhoneApplicationPage一个Web浏览器控件。我要处理硬件后退按钮，并迫使Web浏览器回去。

I have a web browser control embedded into a PhoneApplicationPage. I have to handle the hardware back button and force the web browser to go back.

我know如何处理硬件后退按钮。

I know how to handle hardware back button.

你如何强制web浏览器要到previous页？看似简单的 GoBack的（）和 CanGoBack 的WinForms的网页浏览器属性似乎缺少在Windows Phone上。

How do you force the webbrowser to go to a previous page? The seemingly simple GoBack() and CanGoBack property on WinForms webbrowser seems to be missing on Windows Phone.

推荐答案

如果您通过设置启用的 web浏览器控制脚本 IsScriptEnabled =真则可以使用以下方法来在浏览器中向后导航：

If you enable script on the WebBrowser control by setting IsScriptEnabled="true" you can then use the following to navigate backwards within the browser:

private void backButton_Click(object sender, EventArgs e)
{
  try
  {
    browser.InvokeScript("eval", "history.go(-1)");
  }
  catch
  {
    // Eat error
  }
}

您可以找到这个code（和多一点）的肖Wildermuth的博客文章导航与WP7 WebBrowser控件。

You can find this code (and a bit more) in Shaw Wildermuth's blog post Navigating with the WebBrowser Control on WP7.
