This article introduces native JS writing to be compatible with IE6, 7, and 8 browsers for seamless automatic carousel (with button switching). It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.
The project requirements page is compatible with IE6, 7, 8 and other browsers. We may encounter this carousel effect. The carousel section requires: infinite loop, automatic carousel and Manual switching function, each time scrolling a small grid, there are many such plug-ins on the Internet, such as: swiper, etc.!
But many of them are incompatible with low-level browsers such as IE6, 7, and 8. I have no choice but to write a similar carousel plug-in myself
Without further ado, let’s go directly to the code :
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
<script type="text/javascript" src="js/jquery-1.8.3-20180801.min.js"></script>
<style>
*{margin: 0;padding: 0;}
div{position: relative;width: 1000px;overflow: hidden;height: 100px;line-height:100px;}
ul{position: absolute;list-style: none;overflow: hidden;}
li{float: left;width: 200px;height: 100px;text-align:center;color:#fff;}
a{position: absolute;color:#fff;margin:0 10px;font-size:30px;text-decoration:none;}
</style>
</head>
<body>
<div>
<ul>
<li style="background: red;">1</li>
<li style="background: yellow;">2</li>
<li style="background: blue;">3</li>
<li style="background: black;">4</li>
<li style="background: green;">5</li>
<li style="background: orange;">6</li>
<li style="background: skyblue;">7</li>
<li style="background: blue;">8</li>
<li style="background: green;">9</li>
<li style="background: orange;">10</li>
<li style="background: skyblue;">11</li>
</ul>
<a href="javascript:void(0)" class="prev" style="left:0px;">←</a>
<a href="javascript:void(0)" class="next" style="right:0px;">→</a>
</div>
</body>
<script type="text/javascript">
var fli = $("ul li").clone(true);
var oul = $("ul");
oul.append(fli);
oul.width($("ul li").eq(0).width()*$("ul li").length);
var inow = 0;
var timer = null;
$("div").mouseover(function(){
clearInterval(timer);
})
$("div").mouseout(function(){
autoplay();
})
$(".next").click(function(){
if(inow == $("ul li").length/2){
oul.css("left","0px");
inow = 1;
}else{
inow++;
}
var leng = -inow*$("ul li").eq(0).width()+"px";
oul.animate({"left":leng});
})
$(".prev").click(function(){
if(inow == 0){
var ml = -$("ul li").eq(0).width()*($("ul li").length/2)+"px";
oul.css("left",ml);
inow = $("ul li").length/2-1;
}else{
inow--;
}
var leng = -inow*$("ul li").eq(0).width()+"px";
oul.animate({"left":leng});
})
function autoplay(){
timer = setInterval(function(){
if(inow == $("ul li").length/2){
oul.css("left","0px");
inow = 1;
}else{
inow++;
}
console.log(inow);
var leng = -inow*$("ul li").eq(0).width()+"px";
oul.animate({"left":leng});
},2000);
}
autoplay();
</script>
