网站前端_EasyUI.基础入门.0008.带你玩转jQuery EasyUI Layout组件?

简单介绍:

说明: ($.fn.layout)布局,依赖panel和resizable,默认分为5个区东east,西west,南south,北north,中center,中间的区域面板是必须的,边缘区域面板是可选的,每个边缘区域面板可通过拖拽边框调整尺寸,也可以通过点击折叠触发器来折叠面板.布局可嵌套,因此用户可建立复杂的布局.

基础用法:

<div id="l" class="easyui-layout">
    <div data-options="region:'east',width:100,title:'east title'"></div>
    <div data-options="region:'west',width:200,title:'west title'"></div>
    <div data-options="region:'south',width:100,height:100,title:'south title'"></div>
    <div data-options="region:'north',width:100,height:100,title:'north title'"></div>
    <div data-options="region:'center',title:'center title'">
        <div id="ll" class="easyui-layout" data-options="fit:true">
            <div data-options="region:'west',title:'sub west title',width:200"></div>
            <div data-options="region:'center',title:'sub center title',collapsed:true"></div>
        </div>
    </div>           
</div>
<!-- 说明: 加载jquery-easyui脚本文件 -->
<script src="js/jquery-easyui/jquery.min.js"></script>
<script src="js/jquery-easyui/jquery.easyui.min.js"></script>
<script src="js/jquery-easyui/locale/easyui-lang-zh_CN.js"></script>
<style type="text/css">
    body {
        padding: 0;
        margin: 0;
    }
</style>
<script type="text/javascript">
    var width = $(document).width();
    var height = $(document).height();
    $('#l').layout({
        width: width,
        height: height,
    });
</script>

布局属性:

fit -> boolean

说明: 当设置为true时,就设置布局的尺寸适应它的父容器,当在body标签上创建布局时,它将自动最大化到整个页面的全部尺寸

<body class="easyui-layout" data-options="fit:true">
    <div data-options="region:'east',width:100,title:'east title'"></div>
    <div data-options="region:'west',width:200,title:'west title'"></div>
    <div data-options="region:'south',width:100,height:100,title:'south title'"></div>
    <div data-options="region:'north',width:100,height:100,title:'north title'"></div>
    <div data-options="region:'center',title:'center title'">
        <div id="ll" class="easyui-layout" data-options="fit:true">
            <div data-options="region:'west',title:'sub west title',width:200"></div>
            <div data-options="region:'center',title:'sub center title',collapsed:true"></div>
        </div>
    </div>           
    <!-- 说明: 加载jquery-easyui脚本文件 -->
    <script src="js/jquery-easyui/jquery.min.js"></script>
    <script src="js/jquery-easyui/jquery.easyui.min.js"></script>
    <script src="js/jquery-easyui/locale/easyui-lang-zh_CN.js"></script>
</body>
