学习过程中，使用phonegap开发一个应用。代码如下：
<html>
<head>
<meta charset="utf-8" />
<meta name="format-detection" content="telephone=no" />
<meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1, minimum-scale=1, width=device-width, height=device-height, target-densitydpi=device-dpi" />
<link rel="stylesheet" type="text/css" href="css/index.css" />
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.3.1/jquery.mobile-1.3.1.min.css" />
<script src="http://code.jquery.com/mobile/1.3.1/jquery.mobile-1.3.1.min.js"></script>
<title>Hello World</title>
</head>
<body>
<div data-role="page" id="main-page">
<h1>Apache Cordova</h1>
<div data-role="content">
<div data-role="fieldcontain">
<label for="textinput1">
Title
</label>
<input name="" id="textinput1" placeholder="" value="" type="text">
</div>
<a id="share" data-role="button" data-inline="true" data-theme="a" href="#">
Button
</a>
</div>
</div>
<script type="text/javascript" src="cordova.js"></script>
<script type="text/javascript" src="js/index.js"></script>
<!--<script type="text/javascript" src="js/jquery-1.7.1.min.js"></script>-->
<script type="text/javascript">
app.initialize();
</script>
</body>
但是运行之后按钮显示方式不对。请高手指点，谢谢
