用js判斷 iPhone6 iPhone6 plus iphonex？

 

var events = navigator.userAgent;
if(events.indexOf('Android')>-1 || events.indexOf('Linux')>-1 || events.indexOf('Adr')>-1){
        console.log("安卓手機");
    }else if(events.indexOf('iPhone')>-1){
        //根據尺寸進行判斷 蘋果的型號
        if(screen.height == 812 && screen.width == 375){
// 進行操作，改變樣式

const obj = document.getElementById('sendxBtn')
obj.setAttribute("style", "padding:5px 10px 20px;")

            console.log("蘋果X");
        }else if(screen.height == 736 && screen.width == 414){
            console.log("iPhone7P - iPhone8P - iPhone6");
        }else if(screen.height == 667 && screen.width == 375){
            console.log("iPhone7 - iPhone8 - iPhone6");
        }else if(screen.height == 568 && screen.width == 320){
            console.log("iPhone5");
        }else{
            console.log("iPhone4");
        }
    }else if(events.indexOf('Windows Phone')>-1){
        console.log("諾基亞手機");
        
    }else if(events.indexOf("iPad")>-1){
        console.log("平板");
    }
