导航栏，是用来展示网页主要信息模块，引导用户了解网站概况并帮助其快速找到搜索目标的一种常用元素。导航栏在一个网页中起到了提纲挈领的作用，现在浏览各大网站，基本都能见到它的存在。所以在我们设计网页的时候，这部分是必不可少且需要多下功夫的地方。

1. 页面效果

2. 实现方式

以前写导航栏一般都采用iframe的形式，把页面分成几块，左边导航栏，右边页面主题内容……这次换了一种方式，把导航栏做在了页面初始框架中，每次页面先加载这个初始框架，再根据url请求地址的不同加载不同的主体内容并给导航栏添加效果

左边导航栏：

<div class="row hasfixed" style="margin-right:0;" >
    <!--        navbar-fixed-top固定到顶头-->
    <nav class="navbar navbar-inverse"  role="navigation">
        <div class="navbar-header">
            <a href="http://baidu.com" target="_blank" class="navbar-brand">
                Logo
            </a>
        </div>
        <div class="navbar-header">
            <a class="navbar-brand">
                User：
            </a>
            <a href="./index.php?r=user/basicInfo&userCode=<?php echo Yii::app()->user->name; ?>" class="navbar-brand">
                <?php echo Yii::app()->user->name; ?>
            </a>
            <a href="./index.php?r=user/logout" class="navbar-brand">
                Logout
            </a>
        </div>
    </nav>
</div>
<div class="row" style="margin:0%;">
    <i class="glyphicon glyphicon-th menuDisplay" onclick=menuDisply()></i>

    .navbar {

</style>

程序用的是PHP编程语言，Yii框架，所以通过如下方式获取url中包含的controller和view值，在html代码中直接使用这两个变量即可

<?php
    $controllerId =$this->id; //controller
    $actionId=$this->action->id; //action
?>

当点击左侧菜单栏的子菜单时，会触发一个跳转链接，链接到相对应的页面中。然后根据目的页面做相应的样式渲染，主要根据$controllerId或$actionId判断所在页面，添加相应的class标识，具体的样式由该class设置。
