js判断是pc端还是移动端(包括ipad)

vaildatePc = function() {
    const userAgentInfo = navigator.userAgent;
    const Agents = ["Android", "iPhone",
        "SymbianOS", "Windows Phone",
        "iPad", "iPod"
    ];
    let flag = true;
    for (var v = 0; v < Agents.length; v++) {
        if (userAgentInfo.indexOf(Agents[v]) > 0) {
            flag = false;
            break;
        }
    }
    return flag;
}

true代表pc端，false代表移动端
