关于javascript:移动PCiphoneAndriod是否横屏实用

判断是否是 PC 端

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();
});
