navigator.userAgent获取浏览器信息(类型及系统) 先来看看什么是User-Agent?User-Agent是HTTP请求中的用户标识,一般发送一个能够代表客户端类型的字符串,比如浏览器类型 操作系统等信息。User-Agent 的约定格式是:应用名,跟一个斜线,跟版本号,剩下的是自由的格式。 // 各主流浏览器
function getBrowser() {
var u = navigator.userAgent;
var bws = [{
name: 'sgssapp',
it: /sogousearch/i.test(u)
}, {
name: 'wechat',
it: /MicroMessenger/i.test(u)
}, {
name: 'weibo',
it: !!u.match(/Weibo/i)
}, {
name: 'uc',
it: !!u.match(/UCBrowser/i) || u.indexOf(' UBrowser') > -1
}, {
name: 'sogou',
it: u.indexOf('MetaSr') > -1 || u.indexOf('Sogou') > -1
}, {
name: 'xiaomi',
it: u.indexOf('MiuiBrowser') > -1
}, {
