DNN中的Tab界面

界面模式及使用方式

上面看到的标签功能是一个来组织内容的关键机制。整个DotNetNuke的管理界面都是用这种方式，在自定义模块开发中也完全适用这种界面模式。不过这种模式也可以很容易地用在管理功能之外的区域。

该标签功能是由JavaScript实现的，更具体一点那就是由的一个jQuery插件实现的。首先将你组织你的内容分成逻辑区域，然后就可以将他们组织成标签央视。请查看下面的HTML，CSS和jQuery就知道上面看到它标签样式是如何做到的了。

如果想了解更多的技术信息，请访问这个插件的dnnTabs维基条目。

HTML

  <div class="dnnForm" id="tabs-demo">
        <ul class="dnnAdminTabNav">
            <li><a href="#ChristopherColumbus">Christopher Columbus</a></li>
            <li><a href="#IsaacNewton">Isaac Newton</a></li>
            <li><a href="#JohannesGutenberg">Johannes Gutenberg</a></li>
        </ul>
        <div id="ChristopherColumbus" class="dnnClear">
            <img src="<%=ResolveUrl("Images/498px-Christopher_Columbus.PNG") %>" alt="Christopher Columbus" width="32%" class="dnnLeft" />
            <div class="dnnRight" style="width:62%;margin-left:2%">

CSS
