判断打开目前的是什么手机品牌
要在业务里知道是页面通过什么平台打开的，在前端使用userAgent来进行判断。以下正文涉及3类：主流的手机品牌判断方法、是否在微信打开、是否在PC或Pad打开。
判断业务是否是 iphone、华为、小米、oppo、view、三星 打开
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 isOppo = sUserAgent.match(/oppo/i) == "oppo";
var isOppoR15 = sUserAgent.match(/pacm00/i) == "pacm00";
var isVivo = sUserAgent.match(/vivo/i) == "vivo";
var isXiaomi = sUserAgent.match(/mi\s/i) == "mi ";
var isXiaomi2s = sUserAgent.match(/mix\s/i) == "mix ";
var isRedmi = sUserAgent.match(/redmi/i) == "redmi";
var isSamsung = sUserAgent.match(/sm-/i) == "sm-";
if (isIphone) {
return 'iphone';
} else if (isHuawei || isHonor) {
return 'huawei';
} else if (isOppo || isOppoR15) {
return 'oppo';
} else if (isVivo) {
return 'vivo';
} else if (isXiaomi || isRedmi || isXiaomi2s) {
return 'xiaomi';
} else if (isSamsung) {
return 'samsung';
} else {
return 'default';
}
}
var brand = judgeBrand(navigator.userAgent.toLowerCase()); //调用机型判断
///使用navigator.userAgent.toLowerCase()判断登陆端是pc还是手机
