Question

初学Java applet用户。我不确定为什么我的applet不会显示在页面中。我几乎肯定我有所有必要的信息。是否有可能因使用Safari而无法显示？也不会出现在Chrome中。你看到我错过了什么吗？感谢

编辑：此＆gt;＆gt; Java Applet sandboxed in Safari?也无济于事。

Java程序

  import javax.swing.*;
  import java.awt.*;
  import java.awt.event.*;
  import java.awt.Color.*;

  public class JNumberOne extends JApplet implements ActionListener
  {
      Font numberOneFont = new Font("Teen", Font.BOLD, 24);
      JButton numberOneButton = new JButton("Who's Number One?");
      JLabel numberOneMessage = new JLabel(" ");
      Container con = getContentPane();
      public void init()
   {
       numberOneMessage.setFont(numberOneFont);
       con.add(numberOneButton);
       con.setLayout(new FlowLayout());
       con.setBackground(Color.WHITE);
       numberOneButton.addActionListener(this);
   }
      public void actionPerformed(ActionEvent e)
   {
       con.remove(numberOneButton);
       numberOneMessage.setText("The 1992 Texas Rangers");
       con.add(numberOneMessage);
       con.setBackground(Color.YELLOW);
       validate();
   }
  }

Applet的HTML

  <!DOCTYPE html>
  <html>
      <head>
          <style>
        body{text-align:center; background:#00008B;opacity:.5;}
    </style>
   </head>
   <body>
       <object code = "JNumberOne.class" width=450 height=100></object>
   </body>
  </html>

Answer 1

从类名中删除引号。

替换

 <body>
       <object code = "JNumberOne.class" width=450 height=100></object>
 </body>

使用

 <body>
       <object code = JNumberOne.class width=450 height=100></object>
 </body>
