JS 判断手机横屏还是直屏

查了不少资料，最后结论如下： 复制代码 代码如下: function orientationChange(){ switch(window.orientation) { case 0: // Portrait case 180: // Upside-down Portrait // Javascript to setup Portrait view break; case -90: // Landscape: turned 90 degrees counter-clockwise case 90: // Landscape: turned 90 degrees clockwise // Javascript to steup Landscape view break; } } window.addEventListener("onorientationchange" in window ? "orientationchange" : "resize", orientationChange, false);
