//每过一分钟或刷新页面都会生成新的随机数 <html> <script language="javascript" type="text/javascript"> //返回100-500的随机数 function funGetRandomNum() { return Math.floor(Math.random()*401+100); } </script> <body> <span id="result"> <script language="javascript" type="text/javascript"> document.write(funGetRandomNum()); </script> </span> <script language="javascript" type="text/javascript"> window.setInterval(funGetRandomNum,6000); </script> </body> </html>
JS不会写 但是如果用java貌似可以的 code: Random rnd = new Random(); int numRandom = 0; class ReflashThread extends Thread{ public void run(){ numRandom=rnd.nextInt(400)+100; } Thread.sleep(60000); } public static void main(String args[]){ ReflashThread rThread = new ReflashThread(); rThread.start(); } 随机数就那样生成 你放到网页里去显示就是了
