vue + quasar 使用递归实现动态多级菜单
效果图：
菜单初始化入口 menu.vue，初始化侧边栏菜单组建，
<template>
<q-drawer
v-model="is_hide_"
show-if-above
bordered
content-class="bg-grey-2"
:width="240"
>
<q-scroll-area class="fit">
<my-q-menu/>
q-scroll-area>
q-drawer>
template>
<script>
import MyQMenu from './myQMenu'
export default {
name: 'myMenu',
components: {
MyQMenu },
data () {
return {
leftDrawerOpen: true
}
},
props: ['is_hide'],
computed: {
is_hide_: {
get () {
return this.is_hide }, // boolean 型，用于控制侧边菜单栏是否显示
set () {
}
}
},
}
script>
菜单递归入口
参数说明
@my-router 菜单配置信息
@init-level 初始化菜单缩进大小
<template>
<div>
<q-list>
<my-q-menu-item :my-router="menuList" :init-level="0"/>
q-list>

template>
<script>
import MyQMenuItem from './myQMenuItem'
export default {
name: 'my-q-menu',
components: {
MyQMenuItem },
data () {
return {
menuList: [
{
icon: 'inbox',
label: '菜单1',
children: [
{
icon: 'perm_identity',
label: '菜单1-1',
path: '/about'
},
{
icon: 'delete',
label: '菜单1-2',
children: [
{
icon: 'settings',
label: '菜单2-1',
path: '/noty'
}
]
}
]
},
{
isItemLabel: true,
Label_text: 'item-label '
},
{
icon: 'feedback',
label: '菜单数据结构',
path: '/test',
hidden: false
}
]
}
}
}
script>
菜单元素递归执行体
<template>
<div>
<div v-for="(item,index) in myRouter" :key="index">
<q-item-label v-if="item.isItemLabel" header class="text-weight-bold text-uppercase">
{
{item.Label_text}}
q-item-label>
<div v-if="!item.hidden && !item.isItemLabel">
<div v-if="!item.children">

菜单元素解释
menuList: [
{
icon: 'inbox', //图标
label: '菜单1', //label
children: [
{
icon: 'perm_identity',
label: '菜单1-1',
path: '/about' //路径
},
{
icon: 'delete',
label: '菜单1-2',
children: [
{
icon: 'settings',
label: '菜单2-1',
path: '/noty'
}
]
}
]
},
{
isItemLabel: true, //是否分隔栏
Label_text: 'item-label ' //分隔栏label
},
{
icon: 'feedback',
label: '菜单数据结构',
path: '/test',
hidden: false //是否隐藏
}
