jquery自适应布局的简单实例

代码整理 - uix.layout.js

/**
* Grace [jQuery.js]
*
* UIX页面布局
* [email protected]

* 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

  

  

  

  

  

  


html2:body中

  

  

  

  

  

  


html3:嵌套

  

  

  

  

  

    

    

  
  



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
