转载(一段非常简单的让图片自动切换js代码)

<script language =javascript >
var curIndex=0;
//时间间隔 单位毫秒
var timeInterval=1000;
var arr=new Array();
arr[0]="1.jpg";
arr[1]="2.jpg";
arr[2]="3.jpg";
arr[3]="4.jpg";
arr[4]="5.jpg";
arr[5]="6.jpg";
arr[6]="7.jpg";
setInterval(changeImg,timeInterval);
function changeImg()
{var obj=document.getElementById("obj");
if (curIndex==arr.length-1)
{curIndex=0;}
else {curIndex+=1;}
obj.src=arr[curIndex];}
</script>
<img id=obj src ="1.jpg" border =0 />
