复制代码 代码如下:
function refresh() {
var s = $(".box1");
if (!s.is(":animated"))
$(".box1").animate({ marginLeft: "0px" }, "slow", function () {
$('.box1 img:first').before($('.box1 img:last'));
$(".box1").css("margin-left", "-206px");
});
}
<div class="frame"><div class="box1"><img src="img/001.png" alt="" /><img src="img/002.png" alt="" /><img src="img/003.png" alt="" /><img src="img/004.png" alt="" /></div></div>
<button type="button"><<</button><button type="button" onclick="refresh()">>></button>
.box1
{
width:1200px;
overflow:hidden;
margin-left:-206px;
}
.frame
{
width:620px;
overflow:hidden;
