使用JavaScript判断手机浏览器是横屏还是竖屏问题

//判断手机横竖屏状态：function hengshuping(){if(window.orientation==180||window.orientation==0){alert("竖屏状态！")}if(window.orientation==90||window.orientation==-90){alert("横屏状态！")}}window.addEventListener("onorientationchange" in window ? "orientationchange" : "resize", hengshuping, false);

function orient() {if (window.orientation == 90 || window.orientation == -90) {//ipad、iphone竖屏；Andriod横屏$("body").attr("class", "landscape");orientation = 'landscape';return false;}else if (window.orientation == 0 || window.orientation == 180) {//ipad、iphone横屏；Andriod竖屏$("body").attr("class", "portrait");orientation = 'portrait';return false;}}//页面加载时调用$(function(){orient();});//用户变化屏幕方向时调用$(window).bind( 'orientationchange', function(e){orient();});
