MUI判断手机是横屏还是竖屏

//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);
