js判断当前打开的是不是微信浏览器

代码:

const isWeChat = () => {
  const userAgent = LowerCase();
  return userAgent.includes('micromessenger');
};

判断当前是微信浏览器或者公司app,就显示按钮,否则不显示:

if (isWeChat() || getCookie('appType')) {
  ElementsByClassName("share-box")[0].style.display = "block";
}else{
  ElementsByClassName("share-box")[0].style.display = "none";
}
