提示：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">

</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"
