function ismobile(test) {
  var u = navigator.userAgent,
   app = navigator.appVersion
  if (/AppleWebKit.*Mobile/i.test(navigator.userAgent) || (
    /MIDP|SymbianOS|NOKIA|SAMSUNG|LG|NEC|TCL|Alcatel|BIRD|DBTEL|Dopod|PHILIPS|HAIER|LENOVO|MOT-|Nokia|SonyEricss

function isWeiXin() {
    var ua = window.navigator.userAgent.toLowerCase();
//          console.log(ua);//mozilla/5.0 (iphone; cpu iphone os 9_1 like mac os x) applewebkit/601.1.46 (khtml, like gecko)version/9.0 mobile/13b143 safari/601.1

    } else {
        return false;
    }
}
 

3.識別移動終端手機品牌

function judgeBrand(sUserAgent) {
//      var isIphone = sUserAgent.match(/iphone/i) == "iphone";
  var isHuawei = sUserAgent.match(/huawei/i) == "huawei";
  var isHonor = sUserAgent.match(/honor/i) == "honor";

  var isRedmi = sUserAgent.match(/redmi/i) == "redmi";
  var isSamsung = sUserAgent.match(/sm-/i) == "sm-";
  var isMeizu = sUserAgent.match(/meizu/i) == "meizu";

//      if (isIphone) {
