  当然，看看厨房水槽演示样品 .

  通常只需导航到事件上的URL并实现您自己的 BrowserNavigationCallback 来处理该特定URL的导航 .

  这是来自Kitchen Sink演示通知 setBrowserNavigationCallback 块的代码：

  final WebBrowser wb = new WebBrowser();
      if(wb.getInternal() instanceof BrowserComponent) {
          Button btn = new Button("Add");
          final TextArea content = new TextArea();
          Container north = new Container(new BorderLayout());
          north.addComponent(BorderLayout.CENTER, content);
          north.addComponent(BorderLayout.EAST, btn);
          cnt.addComponent(BorderLayout.NORTH, north);
          content.setHint("Add to web document");
          btn.addActionListener(new ActionListener() {
              public void actionPerformed(ActionEvent evt) {
                  ((BrowserComponent)wb.getInternal()).execute("fnc('" + content.getText() + "');");
              }
          });
          ((BrowserComponent)wb.getInternal()).setBrowserNavigationCallback(new BrowserNavigationCallback() {
              public boolean shouldNavigate(String url) {
                  if(url.startsWith("http://sayhello")) {
                      // warning!!! This is not on the EDT and this method MUST return immediately!
                      Display.getInstance().callSerially(new Runnable() {
                          public void run() {
                              ((BrowserComponent)wb.getInternal()).execute("fnc('this was written by Java code!')");
                          }
                      });
                      return false;
                  }
                  return true;
              }
          });
      }
