非常不多说了，直接给大家贴代码了，具体代码如下所示：
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
<title>Document</title>
<script src="https://cdn.bootcss.com/jquery/3.1.1/jquery.min.js"></script>
</head>
<body>
<ul>
<li>555</li>
<li>555</li>
<li>555</li>
<li>555</li>
</ul>
<button>button</button>
<script type="text/javascript">
var arrary_li = document.querySelectorAll("li");
var num;
$('button').on('click', function () {
$('li').last().addClass('active')
for (var i = 0; i < arrary_li.length; i++) {
if (arrary_li[i].className === 'active') {
num = i;
}
}
localStorage.setItem('num', num)
location.reload()
})
var getNum = parseInt(localStorage.getItem('num'));
$('li').eq(getNum).addClass('active');
</script>
</body>
</html>
