脚本说明:

第一步:把如下代码加入<head>区域中

<SCRIPT LANGUAGE="JavaScript">

<!-- Begin

var Message="欢迎光临南京有线宽带网精彩JavaScript集锦!!";

var place=1;

function scrollIn() {

window.status=Message.substring(0, place);

if (place >= Message.length) {

place=1;

window.setTimeout("scrollOut()",300); 

} else {

place++;

window.setTimeout("scrollIn()",50); 

   } 

}

function scrollOut() {

window.status=Message.substring(place, Message.length);

if (place >= Message.length) {

place=1;

window.setTimeout("scrollIn()", 100);

} else {

place++;

window.setTimeout("scrollOut()", 50);

   }

}

// End -->

</SCRIPT>



第二步:把<body>中的内容改为:

<body bgcolor="#fef4d9" onLoad="scrollIn()">

</textarea>

<SCRIPT LANGUAGE="JavaScript">



<!-- hide



function goHist(a) 



{



   history.go(a);



}



//-->



</script>



<FORM METHOD="post">

<INPUT TYPE="button" VALUE="返回" onClick="goHist(-1)" style="background-color: #8000FF; color: rgb(255,255,255)">

</form>

</center>

<br>

<br>

</body>
