上述应用程序改编自Submitting HTML Forms with JavaFX Webview以前的Oracle论坛问题.@H_403_8@

如果您没有Oracle技术网络帐户来测试上述程序,可以在此处注册一个：https://myprofile.oracle.com/EndUser/faces/profile/createUser.jspx.@H_403_8@

使用JQuery发布到WebView@H_403_8@

另一种实现,我实际上更喜欢使用JavaScript jQuery来内省DOM并执行帖子而不是使用Java DOM apis.有一个使用jQuery on any arbitrary webpage hosted in a WebView的示例.因此,您可以将来自此自动WebView表单帖子和jQuery托管的WebView示例的想法组合在一起,以创建使用JQuery执行帖子的版本.@H_403_8@
