2、利用axios调用后台的文章查询接口 ——> created （无传参）
一、树形菜单功能实现
1、要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，渲染树形节点
v-for渲染节点
定义渲染节点的变量
【LeftNav.vue】
<template>
<el-menu router :default-active="$route.path" default-active="2" class="el-menu-vertical-demo" background-color="#334157"
text-color="#fff" active-text-color="#ffd04b" :collapse="collapsed" >
<!-- <el-menu default-active="2" :collapse="collapsed" collapse-transition router :default-active="$route.path" unique-opened class="el-menu-vertical-demo" background-color="#334157" text-color="#fff" active-text-color="#ffd04b"> -->

</div>
<el-submenu v-for="m in menus" :index="'id_'+m.treeNodeId">
<template slot="title">
<i :class="m.icon"></i>
<span>{{ m.treeNodeName}}</span>
</template>
<el-menu-item v-for="m2 in m.children" :key="'id_'+m2.treeNodeId" :index="m2.url">
<i :class="m2.icon"></i>
<span>{{ m2.treeNodeName}}</span>
</el-menu-item>
</el-submenu>
</el-menu>
</template>
<script>
export default {
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;
});
// 获取树形节点的数据
let url = this.axios.urls.SYSTEM_MENU_TREE;
//this指的是vue实例
this.axios.post(url,{})
.then(resp => {//代表成功 箭头函数 jdk8的语法
console.log(resp);
this.menus=resp.data.result;
}).catch(function (){//代表失败
});
}
}
</script>
<style>
.el-menu-vertical-demo:not(.el-menu--collapse) {
width: 240px;
min-height: 400px;
}
.el-menu-vertical-demo:not(.el-menu--collapse) {
border: none;
text-align: left;
}
.el-menu-item-group__title {
padding: 0px;

</template>
<script>
export default {
name: 'Articles',
data() {
return {
msg: 'Welcome'
}
}
}

<style scoped>
</style>【index.js】
import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from "../components/HelloWorld";
import AppMain from "../components/AppMain";
import LeftNav from "../components/LeftNav";
import TopNav from "../components/TopNav";
import Login from "../views/Login";
import Reg from "../views/Reg";
import Articles from "../views/sys/Articles";
Vue.use(Router)
export default new Router({
routes: [
{
path: '/',
name: 'Login',
component: Login
},
{
path: '/Login',
name: 'Login',
component: Login
},
{
path: '/Reg',
name: 'Reg',
component: Reg
},
{
path: '/AppMain',
name: 'AppMain',
component: AppMain,
children:[
{
path: '/LeftNav',
name: 'LeftNav',
component: LeftNav
},
{
path: '/TopNav',
name: 'TopNav',
component: TopNav

})
二、书籍列表查询
1、el-table 列表组件
2、利用axios调用后台的文章查询接口 ——> created （无传参）
3、el-pagination 列表组件
size-change 页大小改变调用事件
current-change 页面改变调用的事件
4、优化
将调用后台的文章查询接口的代码进行封装，为了复用
5、el-form 查询的筛选条件 （传参）
this.doSeach 公用的查询方法
this.search 带领查询条件的方法
