js判斷端類型

    var ua = navigator.userAgent.toLowerCase();
    var isweixin = (ua.indexOf("micromessenger") === 0 || ua.indexOf("micromessenger") > 0);
    var iswallet = (ua.indexOf("baiduwallet") === 0 || ua.indexOf("baiduwallet") > 0);
    if (!(iswallet || isweixin)) {
        window.location.href = "/sns/limit";
    }
   
  // 優(yōu)化
    var isweixin = (~ua.indexOf("micromessenger"));
    var iswallet = (~ua.indexOf("baiduwallet"));
