如何单击加载到JavaFX Webengine中的网站上的按钮
我是JavaFX的新手。我已成功将网站加载到我的JavaFX应用程序中。我想从我的java应用程序登录到该网站。
到目前为止，我能够将我的登录值插入相应的输入框，但我无法弄清楚如何单击提交按钮。有人能帮我吗。
这是我到目前为止所拥有的。
I am pretty new to JavaFX. I have successfully loaded a website into my JavaFX application. I would like to log in to the website from my java application. So far I am able to insert my login values to the appropriate input box, but I cannot figure out how to click submit button. Can Someone help me. Here is what I have so far.
此处是我的控制器类。
public class Controller implements Initializable{
@FXML
protected TextField usernameLogin;
@FXML
protected TextField passwordLogin;
@FXML
protected Button loginButton;
@FXML
protected WebView webviewBrowser;
@Override
public void initialize(URL location, ResourceBundle resources) {
final WebEngine engine = webviewBrowser.getEngine();
engine.load("http://gmail.com");
engine.setJavaScriptEnabled(true);
loginButton.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent event) {
String username = usernameLogin.getText().toString();
String password = passwordLogin.getText().toString();
engine.getDocument().getElementById("Email").setAttribute("Value", username);
engine.getDocument().getElementById("Passwd").setAttribute("Value", password);
//engine.getDocument().getElementById("submit"). ??submit code??
}
});
}
}
有人可以协助我。我该怎么办才能提交？
谢谢。

我在JavaFX的WebView组件中找到了一个使用html表单的例子： https://community.oracle.com/thread/2510161?start=0&tstart = 0 。
I found this link with an example of working with html forms in JavaFX's WebView component: https://community.oracle.com/thread/2510161?start=0&tstart=0.
以下示例将获取对表单的引用并提交。
The below example will obtain a reference to the form and submit it.
我无法让gmail完全加载到WebView组件内部，因为来自jfxwebkit.dll的错误。
