SPA项目开发之动态树以及数据表格和分页

首先我们来看下数据库

 t_vue_user

 t_vue_tree_node

 

 t_vue_articles

 

 

2. 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="">

2.2 vue+element的el-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>

2.3 数据表格

    <el-table :data="result" style="width: 100%;" :border="true" max-height="550">
      <el-table-column prop="id" label="ID"  min-width="10" align="center"></el-table-column>
      <el-table-column prop="title" label="标题" min-width="20"></el-table-column>
      <el-table-column prop="body" label="内容" min-width="70"></el-table-column>
    </el-table>

<!-- 分页条 -->

    <el-pagination style="margin-top: 20px;" @size-change="handleSizeChange" @current-change="handleCurrentChange"
        :current-page="formInline.page" :page-sizes="[10, 20, 30, 50]" :page-size="100" layout="total, sizes, prev, pager, next, jumper"
        :total="formInline.total">
        </el-pagination>

            handleSizeChange(rows) {
                this.formInline.page = 1;
                this.formInline.rows = rows;
                this.search();
            },
            handleCurrentChange(page) {
                this.formInline.page = page;
                this.search();
            }

 

下面来看下

        <!-- <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"> -->
