js实现简单的图片轮播

 1 <script type="text/javascript">
 2 var n=1;
 3 var map=new Array();
 4 map[0]=new Image();
 5 map[1]=new Image();
 6 map[2]=new Image();
 7 map[3]=new Image();
 8 map[4]=new Image();
 9 map[5]=new Image();
10 map[0].src="images/0.jpg";
11 map[1].src="images/1.jpg";
12 map[2].src="images/2.jpg";
13 map[3].src="images/3.jpg";
14 map[4].src="images/4.jpg";
15 map[5].src="images/5.jpg";
16 function disp()
17 {
18 document.getElementById("img1").src=map[n].src;
19 n=n+1;
20 if (n>5)
21 n=0;
22 window.setTimeout("disp();",2000);
23 }
24 window.setTimeout("disp();",2000);
25 </script>
