3、 encapsulation ：

function envjudge() {
    
    var isMobile = window.navigator.userAgent.match(/(phone|pad|pod|iPhone|iPod|ios|iPad|Android|Mobile|BlackBerry|IEMobile|MQQBrowser|JUC|Fennec|wOSBrowser|BrowserNG|WebOS|Symbian|Windows Phone)/i); //  Whether the mobile terminal 
    var isWx = /micromessenger/i.test(navigator.userAgent); //  Wechat or not 
    var isComWx = /wxwork/i.test(navigator.userAgent); //  Is it enterprise wechat 
            
    if (isComWx && isMobile) {
     // Mobile enterprise wechat

     //PC End enterprise wechat 
        return 'com-wx-pc'
    }
    else if (isWx && isMobile) {
     //  Mobile wechat
