java - 捕获用于 JavaFX WebView/WebEngine 的 URL

Question

我正在尝试创建一个媒体流应用程序。

我有一个包含两个 JFXPanel 的 Jframe。左侧的 JFXPanel 包含一个 WebView，该 WebView 从 www.mediacollege.com 加载示例视频剪辑的链接目录。右侧的 JFXPanel 还包含一个播放视频内容的 WebView。右边的面板目前正在播放来自 www.mediacollege.com 的嵌入式链接。

有人知道我如何在单击它们时捕获左侧 JFXPanel 中的 URL，以便我可以将它们交给右侧面板中的 WebView 进行查看吗？对此的任何帮助将不胜感激。

您需要将 ChangeListener 添加到 WebView 的 WebEngine。 “JavaFX WebView addHyperlinkListener” 解释了如何做到这一点。
