捕获URL以在JavaFX WebView / WebEngine中使用 [英] Capturing a URL for use in JavaFX WebView/WebEngine

问题描述

我正在尝试创建媒体流应用程序。

I am trying to create a media streaming application.

我有一个包含两个JFXPanel的Jframe。左侧的JFXPanel包含一个WebView，用于加载来自www.mediacollege.com的示例视频剪辑链接目录。右侧的JFXPanel还包含播放视频内容的WebView。右边的面板目前正在播放www.mediacollege.com的嵌入式链接。

I have a Jframe that contains two JFXPanel's. The JFXPanel to the left contains a WebView that loads a directory of links of sample video clips from www.mediacollege.com. The JFXPanel to the right also contains a WebView that plays video content. The panel to the right is currently just playing an embedded link from www.mediacollege.com.

有人知道如何在点击它们时在左侧JFXPanel中捕获URL，以便我可以将它们移交给右侧面板中的WebView观看？
我们非常感谢您提供的任何帮助。

Would anybody know how would I capture the URL, s in the left JFXPanel when clicking on them so that I could then hand them over to the WebView in the right Panel for viewing? Any help on this would be greatly appreciated.

推荐答案

你我需要将ChangeListener添加到WebView的WebEngine中。 JavaFX WebView addHyperlinkListener 解释如何这样做。

You'll need to add a ChangeListener to the WebEngine of the WebView. "JavaFX WebView addHyperlinkListener" explains how to do this.
