在没有Gui编辑器的情况下向Gui添加3个jTextArea

Question

我已经完成了学生的工作，我的任务是写一个Auto字汇编，它几乎完成了我面临的一个问题。我必须向gui添加3或4 jTextAreas。问题是他如何编写代码我只能设法添加一个jTextArea。

这看起来像1 Jtextarea：

这就是我希望它拥有它的方式：

以下是管理键盘孔布局的代码：

            button = new CustomJButton[button_size];
            jPanel1 = new javax.swing.JPanel();
            jPanel2 = new javax.swing.JPanel();
            jTextArea = new javax.swing.JTextArea();

            // BorderLayout
            bl = new java.awt.BorderLayout(); 
            this.setLayout(bl);
            this.add(jTextArea, BorderLayout.NORTH);
            Font font1 = new Font("SansSerif", Font.BOLD, 20);
            jTextArea.setFont(font1);
            jTextArea.setFocusable(false);



            menuButtongbc = new GridBagConstraints();
            // vergrößert die Buttons in BEIDE Richtungen // HORIZONTAL / VERTICAL
            menuButtongbc.fill = GridBagConstraints.BOTH;
            menuButtongbc.insets = new Insets(1,1,1,1);
            menuButtongbc.weightx = 1;
            menuButtongbc.weighty = 1;

            letterButtongbc = new GridBagConstraints();
            // vergrößert die Buttons in BEIDE Richtungen // HORIZONTAL / VERTICAL
            letterButtongbc.fill = GridBagConstraints.BOTH;
            letterButtongbc.insets = new Insets(1,1,1,1);
            letterButtongbc.weightx = 1;
            letterButtongbc.weighty = 1;

            jPanel1.setLayout(new java.awt.GridBagLayout());  // Layout left side

Answer 1

创建一个水平框并在水平框中输入3个textareas。

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
 <Script>
 getValue(5);
 function getValue(id){ 
alert(id);
// i am trying this but not done
$.ajax({
type: "POST",
data: {id:id},
url: "http://localhost/key/index2.php/",
success: function(data){
alert(data);

}
});

}
 </script>

in index2.php

<?php
session_start();
$_SESSION['id']=$_POST['id'];
echo $_SESSION['id'];
?>
