如何在iOS上使用Phonegap正确检测方向变化?
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 iPod touch Orientation Events". */
document.body.setAttribute("class", "portrait");
/* Add a descriptive message on "Handling iPhone or iPod touch Orientation Events" */
document.getElementById("currentOrientation").innerHTML = "Now in portrait orientation (Home button on the bottom).";
break;
case 90:
/* If in landscape mode with the screen turned to the left, sets the body's class attribute to landscapeLeft. In this case, all style definitions matching the
body[class="landscapeLeft"] declaration in the iPhoneOrientation.css file will be selected and used to style "Handling iPhone or iPod touch Orientation Events". */
document.body.setAttribute("class", "landscape");
document.getElementById("currentOrientation").innerHTML = "Now in landscape orientation and turned to the left (Home button to the right).";
break;
