关于javascript:移动PCiphoneAndriod是否横屏实用

判断是否是PC端

if (/Android|webOS|iPhone|iPod|BlackBerry/i.test(navigator.userAgent)) {    //挪动端}else{    //PC}

判断是否横屏

function orient() {    console.log($(window).width())    $('.back-box').css('display','none')    if (window.orientation == 90 || window.orientation == -90) {        //ipad、iphone竖屏；Andriod横屏 $("body").attr("class", "landscape");        orientation = 'landscape';        return false;    }    else if (window.orientation == 0 || window.orientation == 180) {        //ipad、iphone横屏；Andriod竖屏 if (/Android|webOS|iPhone|iPod|BlackBerry/i.test(navigator.userAgent)) {            //挪动端                    }else{            //PC        }        $("body").attr("class", "portrait");        orientation = 'portrait';        return false;    }}//页面加载时调用$(function(){    orient();});//用户变动屏幕方向时调用$(window).bind( 'orientationchange', function(e){    orient();});
