如何使用platform.runlater（）在一個webview中禁用鏈接/超鏈接/導航，並在java中的另一個webview中打開該鏈接/超鏈接/導航

Question

[僅供參考，如果你看到的頁面是開起來也一樣，下一個也同這就是爲什麼我要停止上述的WebView的導航因此它可以在開回落僅一] [1]

public class HV extends Application 
    { 
     @Override 
     public void start(Stage primaryStage) throws Exception 
     {     
      StackPane root = new StackPane(); 

     HBox hbox = new HBox(30); // create a HBox to hold 2 vboxes   

     // create a vbox with a textarea that grows vertically 
     VBox vbox = new VBox(10); 
     final WebView img = new WebView(); 
      final WebEngine webEngineImg = img.getEngine();  
     vbox.getChildren().addAll(img); 

     // create a vbox that grows horizontally inside the hbox 
     VBox vbox2 = new VBox();   
     final WebView browser = new WebView(); 
     final WebEngine webEngine = browser.getEngine(); 

     final WebView browser1 = new WebView(); 
     final WebEngine webEngine1 = browser1.getEngine(); 
      webEngine1.getLoadWorker().stateProperty() 
     .addListener(new ChangeListener<Worker.State>() { 
      @Override 
      public void changed(ObservableValue ov, Worker.State oldState, Worker.State newState) { 
      if (newState == Worker.State.SUCCEEDED) { 
      primaryStage.setTitle(webEngine1.getLocation()); 
       String trgurl=webEngine1.getLocation(); 
       System.out.println(trgurl); 


       if(trgurl.matches("(.*)img=(.*)")){ 

        int n = trgurl.indexOf("img="); 
        //String str1 = Integer.toString(n); 
        System.out.println(n+4); 
        int len = trgurl.length(); 
        System.out.println("string length is: "+trgurl.length()); 
        System.out.println(trgurl.substring(n+4,len)); 
        String find = "file:"+trgurl.substring(n+4,len); 
        System.out.println(find); 

        webEngineImg.load(find); 
        //webEngine1.load(find);// this is loading image 

        if (trgurl.matches("(.*)target=wb2(.*)")){ 
         //int n1= trgurl.indexOf("target="); 
         //String str1 = Integer.toString(n); 
        // System.out.println(n1+7); 
        // System.out.println(trgurl.substring(n1+7,98)); 
         boolean cancel(); 
        webEngine.load("url"); 

         } 
       } 
      } 
      } 

     }); 

     webEngine1.load("url"); 
     // String url = "https://eclipse.org"; 
       // Load a page from remote url. 
       // webEngine.load(url); 

     vbox2.setPadding(new Insets(3)); 
     vbox2.setSpacing(3); 
     vbox2.getChildren().addAll(browser1,browser); 

     HBox.setHgrow(vbox2, Priority.ALWAYS); 


     hbox.setPadding(new Insets(20)); 
//  StackPane.setMargin(hbox, new Insets(20)); 

     hbox.getChildren().addAll(vbox, vbox2); 
     root.getChildren().add(hbox); 
     Scene scene = new Scene(root, 500, 300); // the stack pane is the root node 


     primaryStage.setScene(scene); 
     primaryStage.show();   
    } 

    public static void main(String[] args) 
    { 
     Application.launch(args); 

    } 
} 

的debbuging - 這是我的代碼有三個在webview1中的webview完整的網站打開和在webviewimg中只有來自webview1的操作打開和在web視圖中的圖像我想加載一個編輯網址，但爲此我必須在webview1中禁用該鏈接的導航，以便我可以在webview中打開它我有tr Ÿplatform.runlater後運行在其它的WebView但即時得到錯誤狀態不能在串改變該鏈接，這是一段代碼，在那裏我嘗試添加

webEngine1.getLoadWorker().stateProperty() 
     .addListener(new ChangeListener<Worker.State>() { 
      @Override 
      public void changed(ObservableValue ov, Worker.State oldState, Worker.State newState) { 
      if (newState == Worker.State.SUCCEEDED) { 
      primaryStage.setTitle(webEngine1.getLocation()); 
       String trgurl=webEngine1.getLocation(); 
       System.out.println(trgurl); 
      if ((address.getQuery() + "").contains("target=true")) 
      { 
       Platform.runLater(() -> { 
        grid_layout.getChildren().remove(webEngine1); 
        grid_layout.add(webEngine1, 0, 1); 
        webEngine1.load(oldState); 

或如何在Java中插入了jQuery防止導航代碼在這裏

document.addEventListener('click', function(e) { 
    e.stopPropagation(); 
}, true);

問題解決了。下面是代碼：

public class HV extends Application 
{ 

@Override 
public void start(Stage primaryStage) throws Exception 
{ 

    StackPane root = new StackPane(); 

    HBox hbox = new HBox(30); // create a HBox to hold 2 vboxes   

    // create a vbox with a textarea that grows vertically 
    VBox vbox = new VBox(10); 
    final WebView img = new WebView(); 
     final WebEngine Img = img.getEngine();  
    vbox.getChildren().addAll(img); 

    // create a vbox that grows horizontally inside the hbox 
    VBox vbox2 = new VBox();   
    final WebView browser = new WebView(); 
    final WebEngine wb2 = browser.getEngine(); 

    final WebView browser1 = new WebView(); 
    final WebEngine wb1 = browser1.getEngine(); 
     wb1.getLoadWorker().stateProperty() 
    .addListener(new ChangeListener<Worker.State>() { 
     @Override 
     public void changed(ObservableValue ov, Worker.State oldState, Worker.State newState) { 
       Platform.runLater(() -> { 
        final WebEngine wb1 = browser1.getEngine(); 
        if (wb1.getLocation().contains("img")) { 
         System.out.println("BrowserPane.ChangeListener cancelling " + wb1.getLocation()); 
         wb1.getLoadWorker().cancel(); 
         // if (newState == Worker.State.SCHEDULED) { 
         primaryStage.setTitle(wb1.getLocation()); 
         String trgurl = wb1.getLocation(); 
         System.out.println(trgurl); 
          if(trgurl.matches("(.*)img=(.*)")){ 
       int n = trgurl.indexOf("img="); 
       //String str1 = Integer.toString(n); 
       System.out.println(n+4); 
       int len = trgurl.length(); 
       System.out.println("string length is: "+trgurl.length()); 
       System.out.println(trgurl.substring(n+4,len)); 
       String find = "file:"+trgurl.substring(n+4,len); 
       System.out.println(find); 

       Img.load(find); 
         //webEngine1.load(find);// this is loading image 
         if (trgurl.matches("(.*)target=wb2(.*)")){ 
          int n1= trgurl.indexOf("target=wb2"); 
          String str1 = Integer.toString(n1+10); 
          System.out.println(n1+10); 
          System.out.println(trgurl.substring(0,n1+10)); 
          String find1= ""+trgurl.substring(0,n1+10); 
          System.out.println(find1); 
          // boolean cancel(); 
          wb2.load(find1); 
         } 
         } 
         } 
         }); 
         } 
         }); 






    wb1.load("url"); 
    // String url = "https://eclipse.org"; 
      // Load a page from remote url. 
      // webEngine.load(url); 

    vbox2.setPadding(new Insets(3)); 
    vbox2.setSpacing(3); 
    vbox2.getChildren().addAll(browser1,browser); 

    HBox.setHgrow(vbox2, Priority.ALWAYS); 


    hbox.setPadding(new Insets(20)); 
//  StackPane.setMargin(hbox, new Insets(20)); 

    hbox.getChildren().addAll(vbox, vbox2); 
    root.getChildren().add(hbox); 
    Scene scene = new Scene(root, 500, 300); // the stack pane is the root node 


    primaryStage.setScene(scene); 
    primaryStage.show(); 
} 

public static void main(String[] args) 
{ 
    Application.launch(args); 

} 
} 

通過使用platform.runlater（）和聽者後取消由getloadworker.cancel（）的loadworker
