• SPA项目开发之动态树+数据表格+分页


    1、准备好后台(左侧树,带分页的文章查询)

    2、将左侧树的数据绑定到elementui中的menu标签上

    3、新增一个自定义组件用来展示文章列表的

    4、绑定elementui提供的分页组件来完成分页功能

    动态生成NavMenu导航菜单(只支持2级菜单)

    结构:

    <el-menu key="" index="">
    
            <el-submenu>
    
              <template slot="title">
    
                <i class="el-icon-location"></i>
    
                <span>导航一</span>
    
              </template>
    
              <template slot="title">分组一</template>
    
              <el-menu-item route="">

     vue+elementel-menu组件实现路由跳转及当前项的设置

    <el-menu router :default-active="$route.path">
    
     <el-menu-item index="/company/userManager">用户管理</el-menu-item>

      注1:要实现路由跳转,先要在el-menu标签上添加router属性,然后只要在每个el-menu-item标签内

               index属性设置一下url即可实现点击el-menu-item实现路由跳转。

          2:导航当前项,在el-menu标签中绑定  :default-active="$route.path",注意是绑定属性,

               不要忘了加“:”,$route.path等于el-menu-item标签中的index属性值时则该item为当前项。

          3:后台t_tree_node表有几个节点的url为空,则会导致几个节点样式会一致

    动态树:

    <template>
        <el-menu  router :default-active="$route.path"  class="el-menu-vertical-demo" background-color="#334157"
         text-color="#fff" active-text-color="#ffd04b" :collapse="collapsed">
            <!-- <el-menu default-active="2" :collapse="collapsed" collapse-transition router :default-active="$route.path" unique-opened class="el-menu-vertical-demo" background-color="#334157" text-color="#fff" active-text-color="#ffd04b"> -->
            <div class="logobox">
                <img class="logoimg" src="../assets/img/logo.png" alt="">
            </div>
            <!--  注意:index是必填的属性 
            1.index可以看成ID,也就是说它是唯一的 
             2.它代表路由的跳转路径-->
            <el-submenu :index="'id_'+m.treeNodeId" v-for="m in menus">
                <template slot="title">
                    <i :class="m.icon"></i>
                    <span>{{m.treeNodeName}}</span>
                </template>
                    <el-menu-item :key="'id_'+m2.treeNodeId" :index="m2.url" v-for="m2 in m.children">
                         <template slot="title">
                            <i :class="m2.icon"></i>
                            <span>{{m2.treeNodeName}}</span>
                        </template>
                    </el-menu-item>
                
              </el-submenu>

                    menus:[]
                }
            },
            created(){
