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 >

                 < div  class ="accordion"  fillSpace ="sidebar" >
                     < div  class ="accordionHeader" >
                         < h2 >< span > Folder </ span > 界面组件 </ h2 >
                     </ div >
                     < div  class ="accordionContent" >

                         < ul  class ="tree treeFolder" >

                         </ 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。。。

 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。
