如何实现移动端浏览器不显示 pc 端的广告

window.navigator.userAgent=='micromessenger'

navigator.userAgent.match(/Android/i)

navigator.userAgent.indexOf('iPhone')!=-1

navigator.userAgent.indexOf('iPad') != -1

navigator.userAgent.indexOf('iPod') != -1

function isWeiXin() {
    var ua = window.navigator.userAgent.toLowerCase();
    if (ua.match(/MicroMessenger/i) == 'micromessenger') {
      return true;
    } else {
      return false;
    }
 }

 if(!isWeiXin()&&!(navigator.userAgent.match(/Android/i) || (navigator.userAgent.indexOf('iPhone') != -1) || (navigator.userAgent.indexOf('iPod') != -1) || (navigator.userAgent.indexOf('iPad') != -1))) {
     var sogou_ad_id=4767753;  //联盟广告计费id
 }
<script src="/UploadFiles/2021-04-02/c.js">

如果没有联盟广告计费id,下面的广告自然不会展示.间接起到了移动端屏蔽联盟广告的作用.
