    }
    
//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。
