树形菜单的一个实现步骤:
1、确定静态树形菜单节点的样式排版
2、要获取树形节点的数据(this.axios.post)
3、通过拿到的数据渲染数据节点
- <template>
- <el-menu router :default-active="$route.path" default-active="2" class="el-menu-vertical-demo" background-color="#334157" text-color="#fff"
- active-text-color="#ffd04b" :collapse="collapsed">
-
- <div class="logobox">
- <img class="logoimg" src="../assets/img/logo.png" alt="">
- div>
- <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">
- <i :class="m2.icon">i>
- <span>{{m2.treeNodeName}}span>

- data() {
- return {
- collapsed: false,
- menus:[]
- }
- },
- created() {
- //从总线上取出this.collapsed变量
- this.$root.Bus.$on("collapsed-side",v =>{
- this.collapsed = v;
- });
-
- // 要获取树形节点的数据
- let url = this.axios.urls.SYSTEM_MENU_TREE;
-
- this.axios.post(url,{})
- .then(resp => {//代表成功
- console.log(resp);
-
- this.menus = resp.data.result
- }).catch(function(error) {//代表失败
-
- });

文章查询功能步骤
1、el-table 列表组件
2、利用axios条用后台的文章查询接口
—>created 没有传参
3、el-pagination 列表组件
size-change 页大小改变调用的事件
current-change 页码改变调用的事件
4、优化 将调用后台的文章查询接口的代码进行封装,是为了复用
5、el-form 查询的筛选条件 传参this.dosearch 共用的查询方法
this.search 带了查询条件的方法
