javascript判斷iphone/android手機橫豎屏模式

iphone能很好的使用onorientationchange事件，但是android的onresize事件即使不旋轉也會觸發多次。查了不少資料，最後結論如下：function orientationChange(){switch(window.orientation) {case 0: // Portraitcase 180: // Upside-down Portrait// Javascript to setup Portrait viewbreak;case -90: // Landscape: turned 90 degrees counter-clockwisecase 90: // Landscape: turned 90 degrees clockwise// Javascript to steup Landscape viewbreak;}}window.addEventListener("onorientationchange" in window ? "orientationchange" : "resize", orientationChange, false);
