JS判断移动端和pc端加载不同页面

//pc端作判断
<script>
if (/mobile/i.test(navigator.userAgent)) {
window.location = 'http://xxxx/mobile.html'
}
</script>

//移动端端作判断
<script>
if(!/mobile/i.test(navigator.userAgent)){
window.location = 'http://xxxx/pc.html';
}
</script>

// 万能脚本，自动屏蔽 pc
window.addEventListener('DOMContentLoaded', function() {
if (!((/Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i).test(navigator.userAgent))) {
document.documentElement.innerHTML = "<p>请使用手机打开此页面哦~</p>";
}
});
