SPA项目开发之动态树+数据表格+分页

动态生成NavMenu导航菜单(只支持2级菜单)

 <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+element的el-menu组件实现路由跳转及当前项的设

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

导航当前项，在el-menu标签中绑定 :default-active="$route.path",注意是绑定属性，不要忘了加“:”,当$route.path等于el-menu-item标签中的index属性值时则该item为当前项。

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

 <el-menu router :default-active="$route.path">

         <el-menu-item index="/company/userManager">用户管理</el-menu-item>

数据表格

 <el-table :data="result" style="width: 100%;" :border="true" max-height="">

       <el-table-column prop="id" label="ID"  min-width="" align="center"></el-table-column>

       <el-table-column prop="title" label="标题" min-width=""></el-table-column>

       <el-table-column prop="body" label="内容" min-width=""></el-table-column>

     </el-table>

vue中如何修改[数组中][对象的值]

vue 中是无法检测到根据索引值修改的数据变动的

 data:{

      empList:[{eid:,ename:'zs'},{eid:,ename:'ls'}]

    }

    this.empList[].ename="zss";

过Vue数组变异方法可以动态控制数据的增减
第一个参数是要修改的数据, 第二个值是修改当前数组的哪一个字段,第三个是要修改为什么值

   this.$set(this.empList[index], 'ename', 'zss')

    或者

    Vue.set(this.empList[index], 'ename', 'zss')
