下面小編就為大家?guī)硪黄猨query自適應布局的簡單實例。小編覺得挺不錯的，現(xiàn)在就分享給大家，也給大家做個參考。一起跟隨小編過來看看吧
代碼整理 - uix.layout.js
/**
* Grace [jQuery.js]
*
* UIX頁面布局
* 290353142@qq.com
* exp:
* $.uix.layout();//執(zhí)行布局
* class="uix-layout-container";//標識布局容器
* class="uix_box";//用于調(diào)整 布局時將此元素高度鋪滿父容器(支持設置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:
頁面結構動態(tài)修改后調(diào)用 $.uix.layout()即可,若無動態(tài)修改則無需做操作
