问题描述

我正在使用 PHP 类Mobile Detect"来检测用户设备类型(平板电脑/手机)，但是我也想在 javascript 中检测某些设备.有人可以帮我将以下内容转换为 javascript 正则表达式(只需要一个真/假返回)?

I'm using the PHP class "Mobile Detect" to detect user device type (tablet/phone) however I also want to detect certain devices in javascript. Can someone help me convert the following into javascript regex (just need a true/false return)?

var user_agent = navigator.userAgent;

var samsung = 'Galaxy.*Tab|SAMSUNG.*Tablet|Galaxy.*Tab|Android.*GT-';
// if statement checking samsung regex against user agent

var nexus = '^.*Android.*Nexus(((?:(?!Mobile))|(?:(\s(7).+))).)*$';
// if statement checking nexus7 regex against user agent

推荐答案

您在寻找这样的东西吗?

Are you looking for something like this?

var user_agent = navigator.userAgent;

var samsung = /Galaxy.*Tab|SAMSUNG.*Tablet|Galaxy.*Tab|Android.*GT-/i;
// if statement checking samsung regex against user agent
if (samsung.test(user_agent)) {
   // This is a samsung mobile device
}

var nexus = /^.*Android.*Nexus(((?:(?!Mobile))|(?:(\s(7).+))).)*$/i;
// if statement checking nexus7 regex against user agent
if (nexus.test(user_agent)) {
   // This is a nexus mobile device
}
