我有以下代码。我想要实现的是在移动设备的样式之间切换更改方向从纵向到横向(具有大分辨率的设备,如iPhone 4或Galaxy S)
<!doctype html>
<html>
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0" />
<title>KUBIK</title>
<style>
#mobile,
#tablet { display: none; }
@media screen and (max-width: 767px) {
body { background-color: #FF0000; }
#mobile { display: block; }
}
@media screen and (min-width: 768px) and (max-width: 1024px) {
body { background-color: #00FFFF; }
#tablet { display: block; }
}
</style>
</head>
<body>
<div id="mobile">MOBILE</div>
<div id="tablet">TABLET</div>
</body>
</html>
在横向上,iPhone 4的宽度为960px,因此第二条规则应该出现。我将如何实现这一目标?

当方向切换时,iPhone有一个错误。有关javascript修复的信息,请参阅this gist

(function(doc) {
var addEvent = 'addEventListener',
type = 'gesturestart',
qsa = 'querySelectorAll',
scales = [1, 1],
meta = qsa in doc ? doc[qsa]('meta[name=viewport]') : [];
function fix() {
meta.content = 'width=device-width,minimum-scale=' + scales[0] + ',maximum-scale=' + scales[1];
doc.removeEventListener(type, fix, true);
}
if ((meta = meta[meta.length - 1]) && addEvent in doc) {
fix();
scales = [.25, 1.6];
doc[addEvent](type, fix, true);
}
}(document));
