最近换了一家公司工作

因为上家公司老板给的钱不多 还特别会压榨员工

好了好了，不扯皮了

1、封装navbar：

首先需要在pages.json中将对应页面的原生navbar给取消

举例：

{
	"pages": [
		{
		    "path" : "pages/home/index/index",
			"style" :
			{
			    "navigationBarTitleText": "",
				"navigationBarBackgroundColor": "#2EC461",
				"navigationBarTextStyle": "white",
				"navigationStyle": "custom" //取消原生的navbar，即自定义navbar
			}
		}
    ]
}

然后新建一个vue页面文件，进行编写：

<template>
	<uni-nav-bar shadow fixed status-bar background-color="#2EC461" color="#FFF" leftWidth="180rpx" right-width="180rpx">
		<template #left>
			<view>
				<location></location> <!--封装的另一个组件不用管它-->
			</view>
		</template>
		<template #default>
			<view class="navTitle flex-row-centerAll PingFangFont">
				<slot name="title"></slot>
			</view>
		</template>
	</uni-nav-bar>
</template>

<script setup>
	import location from "../location/location"
</script>

<style lang="scss" scoped>
	.navTitle{
		width: 100%;
		height: 100%;
		font-size: 36rpx;
		text-align: center;
		font-weight: bolder;
	}
</style>

然后在需要用到的页面中进行引入：

<template>
	<view>
		<navbar>
            <!--对应封装的navbar组件中的title slot插槽-->
			<template slot="title">
				<view>
					页面标题
				</view>
			</template>
		</navbar>
	</view>
</template>

<script setup>
	import navbar from "../../../components/navbar/navbar"
</script>

<style>
</style>

效果如下： 

 2.封装tabbar组件，新建tabbar.vue组件

<template>
	<view class="tab">
		<view class="navView" @tap="switc('/pages/home/index/index')">
			<image :src="tabname ==='home'?'/static/tabbar/home_selected.png':'/static/tabbar/home.png'" class="navView-img"/>
			<view :class="tabname ==='home'?'tabTextActive':'tabText'">棣栭〉</view>
		</view>
		<view class="navView" @tap="switc('/pages/my/my')">
			<image :src="tabname ==='my'?'/static/tabbar/my_selected.png':'/static/tabbar/my.png'" class="navView-img"/>
			<view :class="tabname ==='my'?'tabTextActive':'tabText'">鎴戠殑</view>
		</view>
	</view>
</template>

<script setup>
import { onMounted } from "vue";
	defineProps({
		tabname:{
			type:String,
			default:'home'
		}
	})
	const switc = (val) => {
		if(!val)return;
		uni.switchTab({url:val})
	}
	onMounted(() => {
		uni.hideTabBar() //隐藏原生的tabbar
	})
</script>

<style lang="scss" scoped>
	.tab{
		position: fixed;
		bottom: 0;
		left: 0;
		display: flex;
		z-index: 1;
		align-items: center;
		width: 100%;
		height: 120rpx;
		background: #fff;
		box-shadow: 0rpx 0rpx 16rpx #999;
		.navView{
			flex: 1;
			text-align: center;
			font-size: 0;
			.navView-img{
				width: 48rpx;
				height: 48rpx;
				margin-bottom: 6rpx;
			}
			.tabText{
				font-size: 26rpx;
				color: #999;
			}
			.tabTextActive{
				font-size: 26rpx;
				color: #333333;
			}
		}
	}
</style>

然后在tabbar页面进行引入

<template>
	<view>
		<navbar>
			<template slot="title">
				<view>
					善星球
				</view>
			</template>
		</navbar>
		<tabbar tabname="home"></tabbar>
	</view>
</template>

<script setup>
	import navbar from "../../../components/navbar/navbar"
	import tabbar from "../../../components/tabbar/tabbar"
</script>

<style>
</style>

看效果：

特地在样式里面加入了盒子阴影进行区分
