提示： 尝试刷新本页，下面的Banner会随机的变化，共三个Banner随机出现。
1.将下面的代码放到摆放广告的地方
<script language="JavaScript"> a = 3 var slump = Math.random(); var talet = Math.round(slump * (a-1))+1; function create() { this.src = '' this.border = '' this.alt = '' } b = new Array() for(var i=1; i<=a; i++) { b[i] = new create() } b[1].src = "../pic/pic01.gif" b[1].border = "0" b[1].alt = "图形一" b[2].src = "../pic/pic02.gif" b[2].border = "0" b[2].alt = "图形二" b[3].src = "../pic/pic03.gif" b[3].border = "0" b[3].alt = "图形三" var visa = ""; visa += '<img src='+b[talet].src+' border="0"'+' alt='+b[talet].alt+'>'; </script> <script language="JavaScript"> <!-- Hide this script from old browsers -- document.write(visa) // --> </script>
2.修改此处为你的Banner路径
b[1].src = "
../pic/pic01.gif
"
b[1].border = "0"
b[1].alt = "图形一"
b[2].src = "
../pic/pic02.gif
"
b[2].border = "0"
b[2].alt = "图形二"
b[3].src = "
../pic/pic03.gif
"
b[3].border = "0"
b[3].alt = "图形三"
