动态菜单(三)

      同学们看了菜单一菜单二有没有什么特殊的感觉。是不是太简单了。

      现在我们结合第一篇文章来做个练习。

      没事的时候会经常找一些好看的UI，留着自己以后做私单的时候用。 比如easyui、EXT JS啊这些。无意中发现了一个国产的框架。那么今天咱也支持国产一把。

      传送门 DWZ框架。感觉还不错 上个图大家看看。

      

 

 

      效果还不错吧？呵呵 这节课我们就抄袭了。。

      先去官方网站下载源代码。传送门

      解压源码打开index.html 页面。HTML的。果断查看源文件。

      这里就不贴代码了。上面是一堆JS根据第一节的“功力”我们可以观察以下代码是菜单

<div id="leftside">
            <div id="sidebar_s">
                <div class="collapse">
                    <div class="toggleCollapse"><div></div></div>
                </div>
            </div>
            <div id="sidebar">

                <div class="toggleCollapse"><h2>主菜单</h2><div>收缩</div></div>

                        </ul>
                    </div>
                </div>

            </div>

        </div>

 

       至于它的点击效果 应该就是页面的JS起的作用。

 接下来新建工程

 

把下载的文件夹里的JS文件啊CSS文件啊 都抄到文件夹里包括主题。

看到JS中有这么一段代码

 1 <script type="text/javascript">
 2 $(function(){
 3     DWZ.init("dwz.frag.xml", {
 4 //        loginUrl:"loginsub.html", loginTitle:"登录",    // 弹出登录对话框
 5         loginUrl:"login.html",    // 跳到登录页面
 6         statusCode:{ok:200, error:300, timeout:301}, //【可选】
 7         pageInfo:{pageNum:"pageNum", numPerPage:"numPerPage", orderField:"orderField", orderDirection:"orderDirection"}, //【可选】
 8         debug:false,    // 调试模式 【true|false】
 9         callback:function(){
10             initEnv();
11             $("#themeList").theme({themeBase:"themes"});
12         }
13     });
14 });
15 </script>

 init这个单词应该就是初始化的缩写。哈哈。。

 那我们就去下载的包里找到

dwz.frag.xml

 

拷贝到根目录下。

包括图片这些。然后在页面上把响应的JS和CSS文件引用上（注意路径）

 

接下来直接把源码copy到工程里。把那些没用的去掉。。。you know。。。（在这里感谢DWZ所有工作人员为我们提供了这么好的框架。支持国产!）

在把我们上面看出来的菜单抽取出来用来后台加载 输出html字符串的形式改写之后差不多就下面这样。。。

<body>
    <form id="form1" runat="server">

    </body>

 只贴了body里面的

接下来我们就要实现绑定的那个方法了。。

数据库跟第一篇的数据库一样。

 

 /// <summary>
        /// 获取左侧便拦组
        /// </summary>
        protected string GetLeftMenu()
        {
            StringBuilder LeftList = new StringBuilder();
            try
            {
                //获取菜单中的所有数据
                DataTable Dt_TotleMenu = SqlHelper.ReturnDataTable("select * from Ziye_Menu", CommandType.Text);
                //取出所有父节点 因为父节点的Menu_Fid=0
                DataRow[] drMenu = Dt_TotleMenu.Select("Menu_Fid=0 and Menu_able=1");
                //构建父节点的table
                DataTable LeftMenuTable = new DataTable();
                //克隆一下解构
                LeftMenuTable = drMenu[0].Table.Clone();
                //导入数据
                foreach (DataRow dr in drMenu)
                {
                    LeftMenuTable.ImportRow(dr);
                }
                //如果存在父节点
                if (LeftMenuTable.Rows.Count != 0)
                {
                    //遍历拼接html 根据第一篇观察和抽取HTML的功夫
                    for (int i = 0; i < LeftMenuTable.Rows.Count; i++)
                    {
                        LeftList.Append("<div class=\"accordionHeader\">");
                        LeftList.Append("<h2><span>Folder</span>" + LeftMenuTable.Rows[i]["Menu_Name"].ToString() + "</h2>");
                        LeftList.Append("</div>");
                        LeftList.Append("<div class=\"accordionContent\" style=\"display:block;\">");

                        LeftList.Append("<ul class=\"tree treeFolder\">");

                        //获取当前父节点的所有子节点
                        DataRow[] drSencondMenu = Dt_TotleMenu.Select("Menu_Fid='" + LeftMenuTable.Rows[i]["Menu_ID"] + "' and Menu_able=1");
                        DataTable SecondTable = new DataTable();
                        SecondTable = drSencondMenu[0].Table.Clone();
                        foreach (DataRow dr in drSencondMenu)
                        {
                            SecondTable.ImportRow(dr);
                        }

                        //如果子存在子节点
                        if (SecondTable.Rows.Count != 0)
                        {
                            //遍历拼接子节点的HTML
                            for (int j = 0; j < SecondTable.Rows.Count; j++)
                            {
                                LeftList.Append("<li><a href=\"" + SecondTable.Rows[j]["Menu_Url"] + "\" target=\"navTab\" rel=\"" + SecondTable.Rows[j]["Menu_Rel"] + "\">" + SecondTable.Rows[j]["Menu_Name"] + "</a></li>");
                            }
                        }
                        //结束符
                        LeftList.Append("</ul>");
                        LeftList.Append("</div>");
                    }

                }
                return LeftList.ToString();

            }
            catch (Exception err)
            {
                return "没菜单";
            }
        }

 这个代码应该比第一篇的简单一些。同学们也可以改成递归的形式。

其实原理跟第一篇的差不多。

OK F5。


 

 最后的效果了。

 

其实这篇文章上周写的好详细。但是一不小心浏览器死了。

博客园没有自动保存功能。只能前功尽弃了。人还是有惰性。主要是感冒了。哎，明天还继续上班。上班悲剧啊！给不上力啊。

下次有机会在给大家介绍一种新型的菜单。这里的技术都是比较过时的了。大家可以用跟得上步伐的代码改造一下。

 

 

到这里菜单已经完成了，下次得去坛子抓一抓问菜单的。

洗洗睡了。

 

忘记贴源码了。

 源码请点击

洗洗睡了。
