问题在标题上。这是jsfiddle。这是代码:
<!DOCTYPE HTML>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title>Back button test</title>
<link href="//code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.css" rel="stylesheet">
<script src="//code.jquery.com/jquery-1.8.1.min.js"></script>
<script src="//code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.js"></script>
</head>
<body>
<div id="home" data-role="page" data-add-back-btn="true">
<div data-role="header"><h1>header</h1></div>
<div data-role="content">content</div>
</div>
</body>
</html>
