function settime(obj) {

if (countdown == 0) {

obj.html("获取验证码");

countdown = 60;

return;

} else {

obj.html(countdown + "s");

countdown--;

}

setTimeout(function () {

settime(obj)

}, 1000)

}

怎么用时间控件做一个60秒的倒计时的程序,求代码 急用啊~~

不添加控件,复制源码即可

Dim WithEvents timer1 As Timer

Dim counter As Integer

Private Sub Form_Load()

counter = 60

Set timer1 = Controls.Add("vb.timer", "Timer1", Me)

With timer1

.Interval = 1000

.Enabled = True

End With

Me.Font.Size = 16

End Sub

Private Sub timer1_timer()

Me.Cls

Me.Print counter

counter = counter - 1

If counter = 0 Then

timer1.Enabled = False

MsgBox "Time is up"

End If

End Sub

java 中 倒计时 一分钟 怎么写?

代码如下:

public class TimeCountDown {

public static void countDown(int seconds) {

System.err.println("倒计时" + seconds + "秒,倒计时开始:");

int i = seconds;

while (i 0) {

System.err.println(i);

try {

Thread.sleep(1000);

} catch (InterruptedException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

i--;

}

System.err.println(i);

System.err.println("倒计时结束");

}

/**

* @param args

*/

public static void main(String[] args) {

// TODO Auto-generated method stub

countDown(60);// 倒计时1分钟

}

}

怎么编写一个倒计时的java的程序?求具体步骤!

基于控制台的话很简单的,我跟你说一下大体思路吧,二话不说先来个for循环,然后输出倒计时的数字,程序睡一秒,在输出倒计时数字,如此循环,简单吧,下面看程序:

public static void main(String[] args) {

for(int i=10;i0;i--){

System.out.print(i+" ");

try {

Thread.sleep(1000);

} catch (InterruptedException e) {

e.printStackTrace();

}

}

System.err.print("爆炸");

}

其他基于网页的还是基于用户界面都可以使用这个思路的

用java编写一个倒计时器代码。

import java.awt.BorderLayout;import java.awt.Container;import java.awt.Font;import java.awt.GridLayout;import java.awt.event.ActionEvent;import java.awt.event.ActionListener;import javax.swing.JButton;import javax.swing.JFrame;import javax.swing.JOptionPane;import javax.swing.JPanel;import javax.swing.JTextField;public class TimerDemo extends JFrame implements ActionListener { private static final long serialVersionUID = 201306211111L; private JTextField screen = new JTextField("0"); private JButton start = new JButton("开始"); private JButton reset = new JButton("重置"); private JPanel panel = new JPanel(); private boolean isRunning; private int time; private int timeBetween; public TimerDemo(int timeBetween) { super("计时器"); this.timeBetween = timeBetween; try { init(); } catch (Exception e) { e.printStackTrace(); } } public TimerDemo() { super("计时器"); this.timeBetween = 100; try { init(); } catch (Exception e) { e.printStackTrace(); } } private void init() { panel.setLayout(new GridLayout()); panel.add(start); panel.add(reset); start.addActionListener(this); reset.addActionListener(this); screen.setFont(new Font("幼圆", Font.BOLD, 60)); screen.setHorizontalAlignment(JTextField.CENTER); screen.setEditable(false); Container c = getContentPane(); c.setLayout(new BorderLayout()); c.add(panel, BorderLayout.SOUTH); c.add(screen, BorderLayout.CENTER); this.setSize(200, 150); this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); this.setResizable(false); this.setLocationRelativeTo(null); this.setVisible(true); } public static void main(String[] args) { new TimerDemo(1);// 设定 1ms/次 // new TimerDemo(); } @Override public void actionPerformed(ActionEvent e) { if (e.getSource() == start) { if (start.getText().equals("开始")) { start.setText("暂停"); isRunning = true; } else if (start.getText().equals("暂停")) { start.setText("开始"); isRunning = false; } } if (e.getSource() == reset) { start.setText("开始"); screen.setText("0"); isRunning = false; time = 0; } new Thread(new TimeZone()).start(); } class TimeZone implements Runnable { @Override public void run() { while (isRunning) { time++; if (time = Integer.MAX_VALUE) { screen.setText("ERROR"); JOptionPane.showMessageDialog(null, "ERROR"); isRunning = false; } screen.setText(String.valueOf(time)); try { Thread.sleep(timeBetween); } catch (Exception e) { e.printStackTrace(); } } } }}
