打开代码，静待5秒后跳转新界面
代码如下：
<!DOCTYPE html>
<html lang="en"><head><meta charset="UTF-8"><meta http-equiv="X-UA-Compatible" content="IE=edge"><meta name="viewport" content="width=device-width, initial-scale=1.0"><title>5秒后跳转界面</title><style>.box {width: 500px;height: 400px;margin: auto;text-align: center;line-height: 400px;font-size: 34px;background-color: aquamarine;}</style>
</head><body><div class="box">距离跳转时间还有5秒</div><script>mop(); //封装到函数里面，先调用一次防止第一次刷新显示空白function mop() {var box = document.querySelector('.box')var shi = 5;setInterval(function() {if (shi == 0) {location.href = 'https://ys.mihoyo.com/';} else {box.innerHTML = '距离跳转时间还有' + shi + '秒';shi--;}}, 1000)}</script>
</body></html>
