我正在寻找一个函数，返回一个布尔值，如果用户正在使用移动浏览器与否。
我知道我可以使用导航器。userAgent并使用regex编写该函数，但是用户代理对于不同的平台来说太复杂了。我怀疑匹配所有可能的设备是否容易，我认为这个问题已经解决了很多次，所以应该有某种完整的解决方案来完成这样的任务。
我正在看这个网站，但不幸的是，脚本是如此神秘，我不知道如何使用它为我的目的，这是创建一个返回true/false的函数。
当前回答
UserAgent不是100%可靠的。
window.navigator.maxTouchPoints > 1;
这就够了!它排除了浏览器开发控制台中的电话模拟器。这对我来说很重要。
其他回答
这就是我用的。我知道userAgent嗅探是不受欢迎的，但我的需求恰好是排除的之一!
<script>
var brow = navigator.userAgent;
if (/mobi/i.test(brow)) {
alert('Mobile Browser');
// Do something for mobile
} else {
alert('Not on Mobile');
// Do something for non mobile
}
</script>
这是他的全部功能
function isMobile(){

}
jQuery.noConflict();
jQuery(document).ready(function(){
if(isMobile()) alert("Mobile"); else alert("Not Mobile");
});
我认为这才是真正的保护方案。
测试在Chrome和Firefox，移动和桌面。
var ___isMobileDevice;
const isMobileDeviceCheck = () => {
const mobileOsRegExp = "(Android|webOS|iPhone|iPod)";
if(screen.width < 500 || navigator.userAgent.match('/'+mobileOsRegExp+'/i')) {
___isMobileDevice = true;
}
if (___isMobileDevice) {
if (typeof window.orientation === "undefined") {
___isMobileDevice = false;
}
}
if (typeof navigator.userAgentData != "undefined" && !navigator.userAgentData.mobile) {
___isMobileDevice = false;
}
if ( typeof window.orientation !== "undefined" && ___isMobileDevice ) {
if (window.navigator.maxTouchPoints > 1 && (navigator.userAgentData.mobile || localStorage.mobile || 'ontouchstart' in document)) {
// mobile device found
console.log('Is mobile device!');
}
}
}
window.onresize = () => {
isMobileDeviceCheck();
}
isMobileDeviceCheck();
PS:作为浏览器扩展的Useragent切换器不能用这段代码欺骗你。
下面是迈克尔•扎波罗哲茨(Michael Zaporozhets)回答的一个不那么含糊的版本。它还使用检查仅在第一次调用时构建正则表达式。关于从正则表达式数组构建字符串的技术，请参阅此回答。
