代码整理 - uix.layout.js
/**
* Grace [jQuery.js]
*
* UIX页面布局
* 290353142@qq.com * exp:
* $.uix.layout();//执行布局
* class="uix-layout-container";//标识布局容器
* class="uix_box";//用于调整 布局时将此元素高度铺满父容器(支持设置padding\margin\border)
* 例： html1:div中
<div class="uix-layout-container">
<div class="uix-layout-north"></div>
<div class="uix-layout-north"></div>
<div class="uix-layout-west"></div>
<div class="uix-layout-east"></div>
<div class="uix-layout-center"></div>
<div class="uix-layout-south"></div>
</div>
html2:body中
<body class="uix-layout-container">
<div class="uix-layout-north"></div>
<div class="uix-layout-north"></div>
<div class="uix-layout-west"></div>
<div class="uix-layout-east"></div>
<div class="uix-layout-center"></div>
<div class="uix-layout-south"></div>
</body>
html3:嵌套
<body class="uix-layout-container">
<div class="uix-layout-north"></div>
<div class="uix-layout-north"></div>
<div class="uix-layout-west"></div>
<div class="uix-layout-east"></div>
<div class="uix-layout-center uix-layout-container">
<div class="uix-layout-north"></div>
<div class="uix-layout-center"></div>
</div>
<div class="uix-layout-south"></div>
</body> js:
页面结构动态修改后调用 $.uix.layout()即可,若无动态修改则无需做操作 *
