js实现图片自动切换效果。

<script language="javascript">
setInterval(test, 2000);
var array = new Array();
var index = 0;
var array = new Array("../../Content/images/3s1hj_kqzew4k2ozbhs2dwgfjeg5sckzsew_780x520.jpg", "../../Content/images/3s1hj_kqzewqs2ozbhsrdwgfjeg5sckzsew_450x600.jpg", "../../Content/images/3s1hj_kqzfc4leozbhmtcugfjeg5sckzsew_650x975.jpg");
function test() {
var myimg = document.getElementById("imgs");
if (index == array.length - 1)
{ index = 0; } else { index++; }
myimg.src = array[index];
}
</script>
