javascript判断iphone/android手机横竖屏模式

iphone能很好的使用onorientationchange事件，但是android的onresize事件即使不旋转也会触发多次。查了不少资料，最后结论如下：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);
