Vue2.0教程 （十一）layout组件
井旺
layout 组件
一、 src/layout/index.vue
<template>
<el-container>
<!-- <sidebar /> -->
<el-main style="margin:0;padding:0;">
<el-container class="main-container">
<el-header class="bg-blue-600">头部</el-header>
<el-main style="margin:0;padding:0;">
<AppMain />
</el-main>
<el-footer class="bg-blue-800">底部</el-footer>
</el-container>
</el-main>
</el-container>
</template>
<script>
import { AppMain } from './components'
export default {
name: 'Layout',
components: {
AppMain
}
}
</script>
二、创建动态组件
components/AppMain.vue
<template>
<section class="app-main">
<div class="app-main-content" style="margin: 12px 12px 0px; zoom: 1;">
<transition name="fade" mode="out-in">
<keep-alive live>
<router-view :key="key" />
</keep-alive>
</transition>
</div>
</section>
</template>
<script>
export default {
name: 'AppMain',
components: {
},
computed: {
key() {
return this.$route.fullPath
}
}
}
</script>
<style lang="scss" scoped>
</style>
以上就是简易版layout组件
下面为完整版的layout组件
<template>
<el-container :class="classObj" class="app-wrapper">
<sidebar class="sidebar-container" />
<el-main style="margin:0;padding:0;">
<el-container :class="{hasTagsView:needTagsView}" class="main-container">
<!-- 头部 -->
<div :class="{'fixed-header':fixedHeader}">
<Navbar />
<tags-view v-if="needTagsView" />
</div>
<!-- 内容 -->
<AppMain />
<!-- 底部 -->
<el-footer class="bg-blue-800">底部</el-footer>
</el-container>
</el-main>
</el-container>
</template>
<script>
import { AppMain, Sidebar, TagsView, Navbar } from './components'
import { mapState } from 'vuex'
export default {
name: 'Layout',
components: {
AppMain,
TagsView,
Navbar,
Sidebar
},
computed: {
...mapState({
sidebar: state => state.app.sidebar,
device: state => state.app.device,
showSettings: state => state.settings.showSettings,
needTagsView: state => state.settings.tagsView,
fixedHeader: state => state.settings.fixedHeader
}),
classObj() {
return {
hideSidebar: !this.sidebar.opened,
openSidebar: this.sidebar.opened,
withoutAnimation: this.sidebar.withoutAnimation
}
}
}
}
</script>
<style lang="scss" scoped>
@import "~@/assets/styles/mixin.scss";
@import "~@/assets/styles/variables.scss";
.app-wrapper {
@include clearfix;
position: relative;
height: 100%;
width: 100%;
&.mobile.openSidebar {
position: fixed;
top: 0;
}
}
.drawer-bg {
background: #000;
opacity: 0.3;
width: 100%;
top: 0;
height: 100%;
position: absolute;
z-index: 999;
}
.fixed-header {
position: fixed;
top: 0;
right: 0;
z-index: 9;
width: calc(100% - #{$sideBarWidth});
transition: width 0.28s;
padding: 0;
}
.hideSidebar .fixed-header {
width: calc(100% - 54px)
}
.mobile .fixed-header {
width: 100%;
}
</style>
三、完整组件
1.src/settings.js
module.exports = {
/**
* @description 网站标题
*/
title: '后台管理',
/**
* @description 是否显示 tagsView
*/
tagsView: true,
/**
* @description 固定头部
*/
fixedHeader: true,
/**
* @description token key
*/
TokenKey: 'authorization',
/**
* @description 请求超时时间，毫秒（默认2分钟）
*/
timeout: 1200000,
/**
* @description 是否显示logo
*/
sidebarLogo: true,
/**
* 是否显示设置的底部信息
*/
showFooter: true,
/**
* 底部文字，支持html语法
*/
footerTxt: 'Copyright© 2022 '
}
2.src/store/getters.js
