//判断手机横竖屏状态: window.addEventListener("onorientationchange" in window ? "orientationchange" : "resize", function() { if (window.orientation === 180 || window.orientation === 0) { alert('竖屏状态!'); } if (window.orientation === 90 || window.orientation === -90 ){ alert('横屏状态!'); } }, false); |
移动端的浏览器一般都支持window.orientation这个参数,通过这个参数可以判断出手机是处在横屏还是竖屏状态
屏幕方向对应的window.orientation值:
ipad,iphone: 90 或 -90 横屏
ipad,iphone: 0 或180 竖屏
Andriod:0 或180 横屏
Andriod: 90 或 -90 竖屏
