自己用bootstrap搭了個項目，純屬娛樂。。。。為了檢驗學習bootstrap之成果。

效果如圖：

一、搭建中發現一問題，因為以前測試都是寫的html頁面，這次用了母版頁，點擊頁面的之後，頁面會刷新，不會保留菜單選中狀態

解決辦法：用js保留上次的值，頁面刷新重新賦值。給當前選中菜單添加class屬性in

  <script type="text/javascript">
        $(function () {
            var divId = localStorage.getItem("id");
            $("#" + divId + ""
 
).addClass(‘in‘);//設置選中項

            $(".panel-body ul li a").click(function () {
                var all_lis = $(this).parents("div").find(".in");
                var id = all_lis[0].id;
                localStorage.setItem("id", id);//保留頁面選中項id
            })
        })

    </script>

二、搭建的手風琴菜單格式不是很好看，微調了一下

 <style type="text/css">
        .header
        {
            width: 99%;
            height: 43px;
            background: #96b97d;
            line-height: 40px;
        }
        .col-sm-2
        {
            position: relative;
            min-height: 1px;
            padding-right: 0px;
            padding
 
-left: 0px;
            top: 0px;
            left: 0px;
        }
        div.col-sm-10
        {
            position: relative;
            min-height: 1px;
            padding-right: 5px;
            padding-left: 5px;
            top: 0px;
            left: 0px;
        }
        h2
        {
            margin-top: 0px;
        }
        .panel-group
        {
            background: #dff0d8;
        }
        .panel-default > .panel-heading
        {
            color: #333;
            background-color: #dff0d8;
            border-color: #ddd;
        }
    </style>

三、搭建手風琴菜單，解析下基本原理：當div的class="panel-collapse collapse in"說明當前菜單最外層菜單被選中，如果移除class屬性in,則菜單收縮。

    <div class="header">
        <center>
            <h2>
                企業管理系統</h2>
        </center>
    </div>
    <div class="col-md-2">
        <div class="panel-group" id="accordion">
            <div class="panel panel-default">
                <div class="panel-heading">
