Let's let the editor take you to learn "how to use JavaScript to make link buttons constantly change".

First, add the following program code to

< head >

< /head >

In the area.

< SCRIPT LANGUAGE="JavaScript" >

< !-- begin // please help yourself to this code. var startTime =null; var timerID =null; var initial =new Date(); var pos =0; var menuItem =null; function initArray() { this.length = initArray.arguments.length for (var i = 0; i < this.length; i++) { this[i+1] = initArray.arguments[i] } } function parsemenuItem(data，num) { for(var i=0;i< data.length;i++) { if(data.substring(i，i+1)=="|") break; } if (num==0) return(data.substring(0，i)); else return(data.substring(i+1，data.length)); } function startTimer() { initial = new Date(); startTime=initial.getTime(); stopTimer(); menuItem = new initArray("赛迪网Windows世界|http://www.ccidnet.com/school/system/"， "赛迪网冲浪指南针|http://www.ccidnet.com/school/net/"， "赛迪网软件下载园|http://www.ccidnet.com/school/soft/"， "赛迪网办公自动化|http://www.ccidnet.com/school/office/"， "赛迪网软件e学堂|http://www.ccidnet.com/school/software/"， "赛迪网多媒体之家|http://www.ccidnet.com/school/multimedia/"， "赛迪网培训与考试|http://www.ccidnet.com/school/exam/"， "赛迪网电脑大词典|http://www.ccidnet.com/school/dict/" ); showTimer(); } function stopTimer() { timerID=null; menuItem=null; //clearTimeout(timerID); } function showTimer() { pos= (pos == menuItem.length) ? 1 : pos + 1; document.forms[0].elements[0]. value=parsemenuItem(menuItem[pos]，0); timerID=window.setTimeout(´showTimer()´，4000); } function goToUrl() { //parent.welcome.location=parsemenuItem(menuItem[pos]，1); this.location=parsemenuItem(menuItem[pos]，1); return (false); } // end -- >

< /SCRIPT >

Note: the links and instructions above can be modified by yourself. 4000 in the above ('showTimer ()', 4000) is used to set the speed of change between links. The smaller the number, the faster the speed.

Add the following code to the

< body >

In the area.

< FORM >

< INPUT TYPE="button" VALUE=" zhouqing " NAME="goTo" onClick="window.goToUrl()" >

< /FORM >

Third, finally put

< body >

Change the contents of the following code.

< body bgcolor="#ffffff" onLoad="window.startTimer()" >
