jQuery Mobile移动开发

1.在<head>元素中包含JavaScript文件是传统的方法。然而,根据Yahoo!”80%的最终用户响应时间在前端上”的说法,这些事件大部分花在资产的下载上,例如样式表,图片,脚本等。减少这些资产的数量明显很重要,在HTML文件的最后包含JavaScript也变得更加常见。这是因为脚本阻止并行下载,也就是说其他资产在每个脚本单独下载完之前无法下载。为了确保脚本放在正确的位置,在</html>结束标记之前包含它。

2.注意:创建自定义 data- 属性的唯一限制是属性的自定义部分的长度至少为一个字符,不能包括大写字母。

3.jQuery Mobile框架一次只能显示其中一个页面,使用 data-title 属性动态改变页面标题。

<!DOCTYPE html>
<html>

<head>
	<meta charset="UTF-8">
	<meta name="viewport" content="width=device-width,initial-scale=UTF-8">
	<title>切换页面</title>
	<link rel="stylesheet" href="css/jquery.mobile-1.4.4.css">
	<script src="js/jquery-1.9.0.js"></script>
	<script src="js/jquery.mobile-1.4.4.js"></script>
</head>

<body class="container">

	<!-- page 1 -->
	<div data-role="page" id="page-one" data-title="Page 1">
	
		<div data-role="header">
			<h1>Page 1</h1>
		</div>
		
		<div data-role="content">
			<p>Body copy for page 1</p>
			<p><a href="#page-two">Link to page 2</a></p>
		</div>
		
		<div data-role="footer">
			Copyright
		</div>
		
	</div>
	
	<!-- page 2 -->
	<div data-role="page" id="page-two" data-title="Page 2">
	
		<div data-role="header">
			<h1>Page 2</h1>
		</div>
		
		<div data-role="content">
			<p>Body copy for page 2</p>
			<p><a href="#page-one">Link to page 1</a></p>
		</div>
		
		<div data-role="footer">
			Copyright
		</div>
		
	</div>
</body>
</html>

4.用jQuery Mobile创建基本的对话框窗口很容易。只要在任何链接锚标记上使用data-rel属性,并将其值设置为dialog。

<!DOCTYPE html>
<html>

<head>
	<meta charset="UTF-8">
	<meta name="viewport" content="width=device-width,initial-scale=UTF-8">
	<title>对话框</title>
	<link rel="stylesheet" href="css/jquery.mobile-1.4.4.css">
	<script src="js/jquery-1.9.0.js"></script>
	<script src="js/jquery.mobile-1.4.4.js"></script>
</head>

<body>

	<div data-role="page">
	
		<div data-role="header">
			<h1>Dialog Test</h1>
		</div>
		
		<div data-role="content">
			<p><a href="#multipage-dialog" data-rel="dialog">Open Muti-page Dialog</a></p>
		</div>
		
		<div data-role="footer">
			Copyright
		</div>
		
	</div>
	
	<div data-role="page" id="multipage-dialog">
	
		<div data-role="header">
			<h1>Multi-page dialog window</h1>
		</div>
		
		<div data-role="content">
			<p><a href="dialog.html" data-rel="back">OK</a></p>
		</div>
		
	</div>
	
</body>
</html>

5.许多输入元素类型被jQuery Mobile自动增强为按钮。这包括类型属性被设置为button,submit,reset或image的输入元素,它们的默认外观都相同。更改这种默认的增强的唯一手段是将data-role设置为none。

 

<!DOCTYPE html>
<html>

<head>
	<meta charset="UTF-8">
	<meta name="viewport" content="width=device-width,initial-scale=UTF-8">
	<title>编辑对话框</title>
	<link rel="stylesheet" href="css/jquery.mobile-1.4.4.css">
	<script src="js/jquery-1.9.0.js"></script>
	<script src="js/jquery.mobile-1.4.4.js"></script>
</head>

<body>

	<div data-role="page">
	
		<div data-role="header">
			<h1>John Doe</h1>
			<a href="#options-dialog" data-icon="gear" class="ui-btn-right" data-rel="dialog">Edit Profile</a>
		</div>
		
		<div data-role="content">
			<p>123 E Street</p>
			<p>Chicago, I1 60622</p>
		</div>
		
		<div data-role="footer">
			Copyright
		</div>
		
	</div>
	
	<div data-role="page" id="options-dialog">
	
		<div data-role="header">
			<h1>Edit John Doe</h1>
			<a href="#" data-icon="check">Save</a>
		</div>
		
		<div data-role="content">
			<label for="profile-image">Profile Image</label>
			<p><img src="images/boy.jpg"></p>
			<input type="file" id="profile-image" name="prfile-image">
			<label for="street-address">Street Address</label>
			<input type="text" id="street-address" name="street-address" value="123 E Street">
			<label for="city">City</label>
			<input type="text" id="city" name="city" value="Chicago">
			<label for="state">State</label>
			<input type="text" id="state" name="state" value="I1">
			<label for="zip-code">Zip Code</label>
			<input type="text" id="zip-code" name="zip-code" value="60622">
		</div>
		
	</div>
	
</body>
</html>

 

<!DOCTYPE html>
<html>

<head>
	<meta charset="UTF-8">
	<meta name="viewport" content="width=device-width,initial-scale=UTF-8">
	<title>controlgroup</title>
	<link rel="stylesheet" href="css/jquery.mobile-1.4.4.css">
	<script src="js/jquery-1.9.0.js"></script>
	<script src="js/jquery.mobile-1.4.4.js"></script>
	<style type="text/css">
		.align-left{ float:left;}
		.align-right{ float:right;}
	</style>
</head>

<body class="container">

	<div data-role="page" id="page-one">
	
		<div data-role="header">
			<div data-role="controlgroup" data-type="horizontal" class="align-left">
				<a href="#" data-role="button" data-icon="home">Home</a>
				<a href="#" data-role="button" data-icon="arrow-l">Back</a>
			</div>
			<div data-role="controlgroup" data-type="horizontal" class="align-right">
				<a href="#" data-role="button" data-icon="delete">Delete</a>
				<a href="#" data-role="button" data-icon="check">Save</a>
			</div>
			<h1>Page</h1>
		</div>
		
		<div data-role="content">
			<p>Body</p>
		</div>
		
		<div data-role="footer">

		</div>
		
	</div>
	
</body>
</html>

 

6.jQuery Mobile框架巧妙地根据按钮数量平均分割navbar的空间。唯一需要注意的是,如果它们包含超过5个超链接,就会开始卷绕到多行。这从某种程度上来说是一种局限,但是也是可取之处,因为移动设备没有足够的水平空间容纳这么多按钮。

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width,initial-scale=UTF-8">
	<title>navbar</title>
	<link rel="stylesheet" href="css/jquery.mobile-1.4.4.css">
	<script src="js/jquery-1.9.0.js"></script>
	<script src="js/jquery.mobile-1.4.4.js"></script>
</head>
<body>
	<div data-role="page">
	
		<div data-role="header" data-fullscreen="true" data-position="fixed">
			<img alt="header" src="images/header.png">
			<div data-role="navbar">
				<ul>
					<li><a href="#" data-icon="home" data-iconpos="top">Home</a></li>
					<li><a href="#" data-icon="arrow-l" data-iconpos="top">Edit</a></li>
					<li><a href="#" data-icon="arrow-r" data-iconpos="top">Search</a></li>
					<li><a href="#" data-icon="arrow-u" data-iconpos="top">About</a></li>
					<li><a href="#" data-icon="arrow-d" data-iconpos="top">Help</a></li>
				</ul>
			</div>
		</div>
		
		<div data-role="content">
			<p>Body</p>
		</div>
		
		<div data-role="footer">
			Copyright
		</div>
		
	</div>
	
</body>
</html>

 

7.网格行--具有ui-block-a类的每个元素自动清除行,建立一个新行。查看jQuery Mobile框架中包含的用于ui-block-a类的实际CSS,你就会发现它清除了左浮动。

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width,initial-scale=UTF-8">
	<title>ui-block</title>
	<link rel="stylesheet" href="css/jquery.mobile-1.4.4.css">
	<script src="js/jquery-1.9.0.js"></script>
	<script src="js/jquery.mobile-1.4.4.js"></script>
</head>
<body>
	<div data-role="page">
	
		<div data-role="header">
			<h1>Head</h1>
		</div>
		
		<div data-role="content">
			<div class="ui-grid-c">
				<div class="ui-block-a">
					<div class="ui-bar ui-bar-b">A</div>
				</div>
				<div class="ui-block-b">
					<div class="ui-bar ui-bar-b">B</div>
				</div>
				<div class="ui-block-c">
					<div class="ui-bar ui-bar-b">C</div>
				</div>
				<div class="ui-block-d">
					<div class="ui-bar ui-bar-b">D</div>
				</div>
				<div class="ui-block-a">
					<div class="ui-bar ui-bar-b">A</div>
				</div>
				<div class="ui-block-b">
					<div class="ui-bar ui-bar-b">B</div>
				</div>
				<div class="ui-block-c">
					<div class="ui-bar ui-bar-b">C</div>
				</div>
				<div class="ui-block-d">
					<div class="ui-bar ui-bar-b">D</div>
				</div>
			</div>
		</div>
		
		<div data-role="footer">
			Copyright
		</div>
		
	</div>
	
</body>
</html>


 

8.为容器添加collapsible  data-role,标题元素自动转换为一个按钮,可用来展开和收起段落。

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width,initial-scale=UTF-8">
	<title>collapsible</title>
	<link rel="stylesheet" href="css/jquery.mobile-1.4.4.css">
	<script src="js/jquery-1.9.0.js"></script>
	<script src="js/jquery.mobile-1.4.4.js"></script>
</head>
<body>
	<div data-role="page">
	
		<div data-role="header">
			<h1>Head</h1>
		</div>
		
		<div data-role="content">
			<div data-role="collapsible" data-collapsed="false">
				<h3>Collapsible content header</h3>
				<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p>
				<div data-role="collapsible">
					<h3>Collapsible child #1</h3>
					<p>Lorem ipsum dolor sit amet.</p>
				</div>
				<div data-role="collapsible">
					<h3>Collapsible child #2</h3>
					<p>Lorem ipsum dolor sit amet.</p>
				</div>
			</div>
		</div>
		
		<div data-role="footer">
			Copyright
		</div>
		
	</div>
	
</body>
</html>


 

9.要定义可折叠面板,必须创建一个包含一组可折叠内容区域的容器元素。在这个容器元素上,data-role必须设置为collapsible-set值。

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width,initial-scale=UTF-8">
	<title>collapsible-set</title>
	<link rel="stylesheet" href="css/jquery.mobile-1.4.4.css">
	<script src="js/jquery-1.9.0.js"></script>
	<script src="js/jquery.mobile-1.4.4.js"></script>
</head>
<body>
	<div data-role="page">
	
		<div data-role="header">
			<h1>Head</h1>
		</div>
		
		<div data-role="content">
			<div data-role="collapsible-set">
				<div data-role="collapsible">
					<h3>Collapsible child #1</h3>
					<p>Lorem ipsum dolor sit amet.</p>
				</div>
				<div data-role="collapsible">
					<h3>Collapsible child #2</h3>
					<p>Lorem ipsum dolor sit amet.</p>
				</div>
			</div>
		</div>
		
		<div data-role="footer">
			Copyright
		</div>
		
	</div>
	
</body>
</html>


 

10. jQuery Mobile在无序列表元素的开始标记中附加了一个值为listview的data-role属性,对这些列表元素进行增强。

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width,initial-scale=UTF-8">
	<title>listview</title>
	<link rel="stylesheet" href="css/jquery.mobile-1.4.4.css">
	<script src="js/jquery-1.9.0.js"></script>
	<script src="js/jquery.mobile-1.4.4.js"></script>
</head>
<body>
	<div data-role="page">
	
		<div data-role="header">
			<h1>Head</h1>
		</div>
		
		<div data-role="content">
			<ul data-role="listview">
				<li><a href="#">Home</a></li>
				<li><a href="#">Articles</a></li>
				<li><a href="#">Videos</a></li>
				<li><a href="#">Books</a></li>
				<li><a href="#">More</a></li>
			</ul>
		</div>
		
		<div data-role="footer">
			Copyright
		</div>
		
	</div>
	
</body>
</html>


 

11.jQuery Mobile框架使得在列表中添加一个搜索过滤栏非常容易:只要为列表添加一个data-filter属性,并将值设置为true即可,可以用附加属性data-filter-placeholder修改默认文本,该属性用于有序列表或者无序列表的开始元素。

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width,initial-scale=UTF-8">
	<title>filter</title>
	<link rel="stylesheet" href="css/jquery.mobile-1.4.4.css">
	<script src="js/jquery-1.9.0.js"></script>
	<script src="js/jquery.mobile-1.4.4.js"></script>
</head>
<body>
	<div data-role="page">
	
		<div data-role="header">
			<h1>Head</h1>
		</div>
		
		<div data-role="content">
			<ul data-role="listview" data-filter="true" data-filter-placeholder="Search the song list ...">
				<li>Across The Universe</li>
				<li>Act Naturally</li>
				<li>Ain't She Sweet</li>
				<li>Baby It's You</li>
				<li>Bad Boy</li>
				<li>Because</li>
			</ul>
		</div>
		
		<div data-role="footer">
			Copyright
		</div>
		
	</div>
	
</body>
</html>


 

12.为滚动条添加高亮显示 data-highlight="true"

<label for="my-slider">My slider</label>
			<input type="range" name="slider" id="my-slider" value="50" min="0" max="100" step="10" data-highlight="true">


 

13.切换开关 data-role="slider"

<label for="flip-switch">Do you like pizza?</label>
			<select name="flip-switch" id="flip-switch" data-role="slider" data-highlight="true">
				<option value="yes">Yes</option>
				<option value="no">No</option>
			</select>


 

14.jQuery Mobile有一个主题系统,包含了由字母“a”到“e”定义的5个样本。样本可以在单个网页上混合和匹配,允许完全自定义,使用样本很简单,只要使用data-theme属性即可。

<a href="#" data-role="button" data-theme="a">Swatch A</a>
			<a href="#" data-role="button" data-theme="b">Swatch B</a>
			<a href="#" data-role="button" data-theme="c">Swatch C</a>
			<a href="#" data-role="button" data-theme="d">Swatch D</a>
			<a href="#" data-role="button" data-theme="e">Swatch E</a>


 

15.jQuery Mobile包含一个名为mobileinit的初始化事件,它在jQuery的document.ready事件之前加载。这使得你可以覆盖和扩展jQuery Mobile的默认全局选项,也是所有自定义的开始。为了扩展mobileinit事件,你必须正确排列JavaScript的顺序。你必须在jQuery Mobile加载之前,jQuery框架加载之后包含自定义JavaScript事件处理器。
