最近看了 Vue.js 的递归组件，实现了一个最基本的树形菜单。

项目结构：

main.js 作为入口，很简单：

import Vue from 'vue'Vue.config.debug = trueimport main from './components/main.vue'new Vue({ el: '#app', render: h => h(main)})登录后复制

它引入了一个组件 main.vue：

<template> <p class="tree-menu"> <ul v-for="menuItem in theModel"> <my-tree :model="menuItem"></my-tree> </ul> </p></template><script>var myData = [ { &#39;id&#39;: &#39;1&#39;, &#39;menuName&#39;: &#39;基础管理&#39;, &#39;menuCode&#39;: &#39;10&#39;, &#39;children&#39;: [ { &#39;menuName&#39;: &#39;用户管理&#39;, &#39;menuCode&#39;: &#39;11&#39; }, { &#39;menuName&#39;: &#39;角色管理&#39;, &#39;menuCode&#39;: &#39;12&#39;, &#39;children&#39;: [ { &#39;menuName&#39;: &#39;管理员&#39;, &#39;menuCode&#39;: &#39;121&#39; }, { &#39;menuName&#39;: &#39;CEO&#39;, &#39;menuCode&#39;: &#39;122&#39; }, { &#39;menuName&#39;: &#39;CFO&#39;, &#39;menuCode&#39;: &#39;123&#39; }, { &#39;menuName&#39;: &#39;COO&#39;, &#39;menuCode&#39;: &#39;124&#39; }, { &#39;menuName&#39;: &#39;普通人&#39;, &#39;menuCode&#39;: &#39;124&#39; } ] }, { &#39;menuName&#39;: &#39;权限管理&#39;, &#39;menuCode&#39;: &#39;13&#39; } ] }, { &#39;id&#39;: &#39;2&#39;, &#39;menuName&#39;: &#39;商品管理&#39;, &#39;menuCode&#39;: &#39;&#39; }, { &#39;id&#39;: &#39;3&#39;, &#39;menuName&#39;: &#39;订单管理&#39;, &#39;menuCode&#39;: &#39;30&#39;, &#39;children&#39;: [ { &#39;menuName&#39;: &#39;订单列表&#39;, &#39;menuCode&#39;: &#39;31&#39; }, { &#39;menuName&#39;: &#39;退货列表&#39;, &#39;menuCode&#39;: &#39;32&#39;, &#39;children&#39;: [] } ] }, { &#39;id&#39;: &#39;4&#39;, &#39;menuName&#39;: &#39;商家管理&#39;, &#39;menuCode&#39;: &#39;&#39;, &#39;children&#39;: [] }];import myTree from &#39;./common/treeMenu.vue&#39;export default { components: { myTree }, data() { return { theModel: myData } }}</script>登录后复制

该文件引入了树形组件 treeMenu.vue：

<template> <li> <span @click="toggle"> <i v-if="isFolder" class="icon" :class="[open ? &#39;folder-open&#39;: &#39;folder&#39;]"></i> <i v-if="!isFolder" class="icon file-text"></i> {{ model.menuName }} </span> <ul v-show="open" v-if="isFolder"> <tree-menu v-for="item in model.children" :model="item"></tree-menu> </ul> </li></template> <script>export default { name: &#39;treeMenu&#39;, props: [&#39;model&#39;], data() { return { open: false, isFolder: true } }, computed: { isFolder: function() { return this.model.children && this.model.children.length } }, methods: { toggle: function() { if (this.isFolder) { this.open = !this.open } } }}</script> <style>ul { list-style: none;}i.icon { display: inline-block; width: 15px; height: 15px; background-repeat: no-repeat; vertical-align: middle;}.icon.folder { background-image: url(/src/assets/folder.png);}.icon.folder-open { background-image: url(/src/assets/folder-open.png);}.icon.file-text { background-image: url(/src/assets/file-text.png);}.tree-menu li { line-height: 1.5;}</style>登录后复制

就这么简单。这篇文章还真没什么可写的，权当记录吧。
