vue3之vite创建h5项目之2 （ ）
1：安装sass
1-1 使用sass引入公共样式1
1-1-1 main.ts 引入公共样式方式
import '@/style/index.scss'
1-2 vite.config.ts 引入公共样式方式2
export default defineConfig({
css: {
preprocessorOptions: {
scss: {
additionalData: `
@import "@/style/reset.scss";
@import "@/style/mixin.scss";
@import "@/style/variables.scss";
`,
},
},
},
})
1-3样式文件
1-3-1 src / style / index.scss ( 适配iphonex等还有引入其他公共的样式 )
@import './reset.scss';
@import './variables.scss';
@import './mixin.scss';
html,
body,
#app {
height: 100%;
color: #333333;
font-family: Arial, Helvetica, 'STHeiti STXihei', 'Microsoft YaHei', Tohoma, sans-serif;
background-color: $background-color;
}
.app-container {
padding-bottom: 50px;
}
#__vconsole {
display: none;
}
.fixIphonex {
padding-bottom: $safe-bottom !important;
&::after {
content: '';
position: fixed;
bottom: 0 !important;
left: 0;
height: calc(#{
$safe-bottom} + 1px);
width: 100%;
background: #ffffff;
}
}
@supports (bottom: env(safe-area-inset-bottom)) {
.app-container {
padding-bottom: calc(env(safe-area-inset-bottom) + 50px);
}
.bottom-button-box {
bottom: env(safe-area-inset-bottom);
&:after {
content: '';
height: env(safe-area-inset-bottom);
position: absolute;
top: 100%;
left: 0;
right: 0;
background-color: #fff;
}
}
}
1-3-2 src / style / mixin.scss （ 公共样式方法抽离 ）
@mixin clearfix {
&:after {
content: "";
display: table;
clear: both;
}
}
@mixin textoverflow($clamp:1) {
display: block;
overflow: hidden;
text-overflow: ellipsis;
-o-text-overflow: ellipsis;
display: -webkit-box;
-webkit-line-clamp: $clamp;
-webkit-box-orient: vertical;
}
@mixin flexbox($jc:space-between, $ai:center, $fd:row, $fw:nowrap) {
display: flex;
display: -webkit-flex;
flex: 1;
justify-content: $jc;
-webkit-justify-content: $jc;
align-items: $ai;
-webkit-align-items: $ai;
flex-direction: $fd;
-webkit-flex-direction: $fd;
flex-wrap: $fw;
-webkit-flex-wrap: $fw;
}

1-3-4 src / style / variables.scss （ 定义的公共变量样式 ）
$background-color: #f8f8f8;
$theme-color: #07b0b8;
$safe-bottom: constant(safe-area-inset-bottom);
$safe-bottom: env(safe-area-inset-bottom);
1-3-5 使用变量
<template>
<div>
App
<div class="rrrr">rrrr</div>
</div>
</template>
<script setup lang="ts" name='App'>
import {
} from 'vue'
console.log("meta.env", import.meta.env)
</script>
<style lang="scss" scoped>
.rrrr {
color: $theme-color;
}
</style>
2：声明组件 否则ts报红线 项目根目录 / env.d.ts
declare module '*.vue' {
import type {
DefineComponent } from 'vue';
const vueComponent: DefineComponent<{
}, {
}, any>;
export default vueComponent;
}
3：路由配置和layout组件配置
3-1 路径文件 router/index.ts
import type {
RouteRecordRaw} from 'vue-router'
import {
createRouter, createWebHistory } from 'vue-router'
import Layout from '@/views/layout/index.vue'
const routes: Array<RouteRecordRaw> = [
{
path: '/',
name: 'Home',
redirect: '/home',
meta: {
title: '首页',
keepAlive: false
},
component: Layout,
children: [
{
path: '/home',
name: 'Home',
component: () => import('@/views/home/index.vue'),
meta: {
title: '首页', keepAlive: false, showTab: true }
},
{
path: '/about',
name: 'About',
component: () => import('@/views/about/index.vue'),
meta: {
title: '关于', keepAlive: false, showTab: true }
},
{
path: '/test',
name: 'Test',
component: () => import('@/views/test/index.vue'),
meta: {
title: '测试', keepAlive: false, showTab: true }
},
{
path: '/mine',
name: 'Mine',
component: () => import('@/views/mine/index.vue'),
meta: {
title: '我的', keepAlive: false, showTab: true }
},
{
path: '/noTab',
name: 'NoTab',
component: () => import('@/views/noTab/index.vue'),
meta: {
title: '没有Tab', keepAlive: false, showTab: false }
},
]
}
]
const router = createRouter({
history: createWebHistory(import.meta.env.BASE_URL),
routes
})
export default router
3-2 Layout组件 view / layout / index.vue
<template>
<div class="layout">
<div class="layout-content" :class="[route.meta.showTab ? 'showTab' : 'noShowTab']">
<keep-alive v-if="route.meta.keepAlive">
<router-view></router-view>
</keep-alive>
<router-view v-else></router-view>
</div>
<div class="layout-footer" v-if="route.meta.showTab">
<TabBar :tabbars="tabbars" v-model="activeRoute" @change="handleChange" />
</div>
</div>
</template>
<script setup lang="ts" name="LayoutIndex">
import TabBar from "@/components/TabBar.vue"
import {
useRoute } from 'vue-router'
import type {
ITabList } from '@/components/TabBar.vue'
import {
reactive, watch, ref } from 'vue'
const route = useRoute()
console.log(route.meta)
const tabbars: Array<ITabList> = reactive([
{
title: '首页', to: '/home', icon: 'home-o' },
{
title: '关于', to: '/about', icon: 'label-o' },
{
title: '测试', to: '/test', icon: 'star-o' },
{
title: '我的', to: '/mine', icon: 'user-o' }
])
const activeRoute = ref(0)
watch(activeRoute, (v) => {
console.log('tab value v-model:', v)
})
const handleChange = (v: number) => {
console.log('tab value @change:', v)
}
watch(route, (v) => {
console.log('route', v.name)
})
</script>
<style lang="scss" scoped>
.layout {
background: #fff;
width: 100%;
height: 100%;
.layout-content {
background: #d5d5d5;
}
.showTab {
height: calc(100% - 50px);
overflow-y: scroll;
}
.noShowTab {
height: 100%;
overflow-y: scroll;
}
}
</style>
3-3 TabBar.vue 组件 src / components/ abBar.vue
<script setup lang="ts">
import {
computed,defineProps ,defineEmits } from 'vue'
import type {
PropType } from 'vue';
export interface ITabList {
title: string
to: string
icon: string
}
const props = defineProps({
tabbars: {
type: Array as PropType<ITabList[]>,
default: () => []
},
active: Number
})
const emit = defineEmits(['change', 'update:active'])
const active = computed({
get: () => props.active,
set: (val) => {
emit('update:active', val)
emit('change', val)
}
})
</script>
<template>
<van-tabbar v-model="active" route fixed>
<van-tabbar-item v-for="item in tabbars" :to="item.to" :icon="item.icon" :key="item.to">
{
{
item.title }}
</van-tabbar-item>
</van-tabbar>
</template>
3-4 使用到van组件库
- 安装：
pnpm i vant@next -S
- main.ts
import 'vant/lib/index.css';
import {
Tabbar,TabbarItem } from 'vant';
const app = createApp(App)
app.use(Tabbar);
app.use(TabbarItem);
3-5 App.vue
<template>
<router-view />
</template>
<script setup lang="ts" name='App'>
import {
} from 'vue'
console.log("meta.env", import.meta.env)
</script>
<style lang="scss" scoped>
#app {
height: 100%;
width: 100%;
}
</style>
3-6 效果
