我在下面找到了这个方向测试代码,寻找JQTouch参考资料.这在移动Safari上的iOS模拟器中正常工作,但在Phonegap中无法正确处理.我的项目遇到了与杀死此测试页面相同的问题.有没有办法在Phonegap中使用JavaScript来感知方向变化？

window.onorientationchange = function() {
  /*window.orientation returns a value that indicates whether iPhone is in portrait mode, landscape mode with the screen turned to the
    left, or landscape mode with the screen turned to the right. */
  var orientation = window.orientation;
  switch (orientation) {
    case 0:
      /* If in portrait mode, sets the body's class attribute to portrait. Consequently, all style definitions matching the body[class="portrait"] declaration
         in the iPhoneOrientation.css file will be selected and used to style "Handling iPhone or …

我昨天开始研究PhoneGap并在倾斜手机的同时创造了一个简单的"大理石".我目前正在使用Android进行开发,但我希望这种方向可以保持美化,而不是在手机旋转时移动.有办法做到这一点吗？
