如何让层轮番显示，间隔时间为3秒？

Question

用个SPAN装起来，动态改变innerHTML属性呀。

Answer 1

我写了，我的层是动态生成的。
<%For i=0 to rs.recordcount-1%>
<div id="Layer<%=i%>">
是不是这样的？

Answer 2

<%For i=0 to rs.recordcount-1%>
<div id="Layer<%=i%>" style="display:none;">
<%next%>
<script language="javascript">
var allLayers=new Array();
<%For i=0 to rs.recordcount-1%>
allLayers[<%=i%>]="Layer<%=i%>";
<%next%>
var i=0;
function ShowItems(){
document.getElementById(allLayers[i]).style.display="none";
if(i=allLayers.length-1){i=0;}else{i++}
document.getElementById(allLayers[i]).style.display="";
setTimeout("ShowItems()",3000);
}
ShowItems();
</script>
思路是这样.

Answer 3

if(i==allLayers.length-1){i=0;}else{i++}

Answer 4

<div id="Layer0" style="display:none;">123123</div>
<div id="Layer1" style="display:none;">aaaaaa</div>
<div id="Layer2" style="display:none;">1sdf33</div>
<script language="javascript">
var allLayers=new Array();
allLayers[0]="Layer0";
allLayers[1]="Layer1";
allLayers[2]="Layer2";
var i=2;
function ShowItems(){
document.getElementById(allLayers[i]).style.display="none";
if(i==allLayers.length-1){i=0;}else{i++}
document.getElementById(allLayers[i]).style.display="";
setTimeout("ShowItems()",3000);
}
ShowItems();
</script>
我这里测试通过.
