af3的变化非常大。参见[译]Intel App Framework 3.0的变化

  一、应用需要引用的js脚本:

  af3中不在自己实现dom选择器,而是选择基于jquey或兼容jquery的库如zepto等,touch layer也依靠fastclick。下面就是af3应用的head部分示意代码,对比2.x变化很明显,这里引入了jquery和fastclick,没有了appframework.js

 <head>
<title>LearAF3</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<link rel="stylesheet" type="text/css" href="js/af3.0/af.ui.css" />
<link rel="stylesheet" type="text/css" href="js/af3.0/icons.min.css" />
<script src="js/libs/jquery/jquery-2.1.1.min.js"></script>
<script src="js/libs/fastclick/fastclick-1.0.3.min.js"></script>
<script src="js/af3.0/appframework.ui.js"></script>
   ...
</head>

  二、页面组织结构:

  af3中应用视觉元素组织变化巨大,一改2.x时代panel和header,footer混乱的现象,3.0中新增加了一个顶级元素类型(除afui)view,现在header,footer和panel页面都属于view元素,一个view内部的panel有相同的header和footer,需要不同的footer或header需要创建新的view,窃以为这样清爽多了:),请看:

<body>
<div class="view" id="viewMain">
<header>
<h1 class="title">Main view</h1>
<a class="button icon menuButton" style="float:right"></a>
</header>
<div class="pages">
<div class="panel active" id="page01"> this is page in main view</div>
</div>
<footer>
<a data-transition="up-reveal" class="icon html5" onclick="$.afui.loadContent('#view2',false,false,'slide');">Next view</a>
</footer>
</div>
<div class="view active" id="view2">
<header>
<h1 class="title">view 22</h1>
<a class="button icon menuButton" style="float:right"></a>
</header>
<div class="pages">
<div class="panel active" id="page22" >
<p>this is page in view 2</p>
</div>
</div>
<footer>
<a href="#viewMain" data-transition="up-reveal:back" class="icon home">back to main view</a>
</footer>
</div>
</body>

需要注意的是,view中的panel元素,还需要包裹一层pages元素,即使只有一个panel。

代码中同时显示了切换view的三种方式:

  1. 编辑时,通过添加active 类名来指定默认view
  2. 运行时,通过锚定view的id来切换
  3. 运行时,通过js函数loadContent

  三、自定义themes:

  af3中默认使用系统theme,如果你需要自定义theme,需要设定useOSThemes为false

$.afui.useOSThemes=false; //This must be set before $(document).ready()

另外,还需要在view之外再包裹一层id为afui的div元素,并指定相应theme的class。af3内置的theme有:

ios,ios7,android(light,dark),win8(light dark),bb/*blackberry*/,tizen

  四、总体代码:

<!DOCTYPE html>
<!--

and open the template in the editor.
-->
<html>
<head>
<title>LearAF3</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<link rel="stylesheet" type="text/css" href="js/af3.0/af.ui.base.css" />
<link rel="stylesheet" type="text/css" href="js/af3.0/af.ui.css" />
<link rel="stylesheet" type="text/css" href="js/af3.0/icons.min.css" />
<script src="js/libs/jquery/jquery-2.1.1.min.js"></script>
<script src="js/libs/fastclick/fastclick-1.0.3.min.js"></script>
<script src="js/af3.0/appframework.ui.js"></script>
<script>
$.afui.useOSThemes=false;
</script>
</head>
<body>
<div id="afui" class="bb">
<div id="splashscreen">
<h1>Lear App Framework 3</h1>
<span class="icon loading">loading...</span>
</div>
<div class="view" id="viewMain">
<header>
<h1 class="title">Main view</h1>
<a class="button icon menuButton" style="float:right"></a>
</header>
<div class="pages">
<div class="panel" id="page1">
<p>this is page in main view</p>
</div>
</div>
<footer>
<a data-transition="up" class="icon html5" onclick="$.afui.loadContent('#view2',false,false,'up');">Next view</a>
</footer>
</div>
<div class="view active" id="view2">
<header>
<h1 class="title">view 22</h1>
<a class="button icon menuButton" style="float:right"></a>
</header>
<div class="pages">
<div class="panel active" id="page2" >
<p>this is page in view 2</p>
</div>
</div>
<footer>
<a href="#viewMain" data-transition="up:back" class="icon home">back to main view</a>
</footer>
</div>
</div>
</body>
</html>

  五、导航历史(history):

  af3为每个view,单独记录页面(panel)的浏览记录。

  目前发现af3中每个view下面必须指出默认panel,否则不显示默认panel。并且需要通过给panel添加active类名,而不是通过data-selected="true"
