判斷瀏覽器是不是手機端

在項目中常常會有須要判斷瀏覽器是不是手機端仍是PC端，這裏有2個函數 供參考：

let isMobile = function() {
	let userAgentInfo = navigator.userAgent.toLowerCase();
	let Agents = new Array('android', 'iphone', 'symbianos', 'windows phone', 'ipad', 'ipod');
	let flag = false;
	for (let v = 0; v < Agents.length; v++) {
		if (userAgentInfo.indexOf(Agents[v]) !== -1) {
			flag = true;
			break;
		}
	}
	return flag;
};

 

用法：

let ismobileBool = isMobile(); 

//true 表明是手機端，false表明是PC端

 

另一個函數也是能夠 用做判斷

var browserRedirect=function () {
            var sUserAgent = navigator.userAgent.toLowerCase();
            var bIsIpad = sUserAgent.match(/ipad/i) == "ipad";
            var bIsIphoneOs = sUserAgent.match(/iphone os/i) == "iphone os";
            var bIsMidp = sUserAgent.match(/midp/i) == "midp";
            var bIsUc7 = sUserAgent.match(/rv:1.2.3.4/i) == "rv:1.2.3.4";
            var bIsUc = sUserAgent.match(/ucweb/i) == "ucweb";
            var bIsAndroid = sUserAgent.match(/android/i) == "android";
            var bIsCE = sUserAgent.match(/windows ce/i) == "windows ce";
            var bIsWM = sUserAgent.match(/windows mobile/i) == "windows mobile";

            if (bIsIpad || bIsIphoneOs || bIsMidp || bIsUc7 || bIsUc || bIsAndroid || bIsCE || bIsWM) {
                //若是是上述設備就會以手機域名打開
                return 'mobile';
            } else {
                //不然就是電腦域名打開
                return 'pc';
            }
        }

 

用法爲： var browser =  browserRedirect();

//mobile 爲手機， pc爲PC端
