3. 自定义tabbar
<!-- 自定义底部导航栏 -->
<template>
<view class="tabbar-container" :style="{backgroundImage:'url('+bg+')'}">
<!-- :style="['width: calc(100% /' + tabbar.length + ')']" -->
<view class="tabbar-item" :class="[item.centerItem ? ' center-item' : '']" @click="changeItem(item)"
v-for="(item, i) in tabbar" :key="i">
<view class="item-top">
<image :src="curItem === item.id ? item.selectedIconPath : item.iconPath" />
</view>
<view class="item-bottom" :class="[curItem === item.id ? 'item-active' : '']">{{ item.text }}</view>
</view>
</view>
</template>
<script>
export default {
props: {
/* 当前导航栏 */
currPage: {
type: Number,
default: 0
}
},
data() {
return {
curItem: 0, // 当前所选导航栏
bg: 'https://*******/tabbar-bg.jpg',
tabbar: [{
id: 0,
pagePath: "/pages/ballroom/ballroom",
text: "球类房",
iconPath: '/static/tabbar-icon/ball.png',
selectedIconPath: '/static/tabbar-icon/ball-actived.png',
centerItem: false
},
{

selectedIconPath: '/static/tabbar-icon/yoga-actived.png',
centerItem: false
},
{
id: 3,
pagePath: "/pages/league-class/league-class",
text: "团课",
iconPath: '/static/tabbar-icon/league.png',
selectedIconPath: '/static/tabbar-icon/league-actived.png',
centerItem: false
},
{
id: 4,
pagePath: "/pages/my-reservation/my-reservation",
text: "我的预定",
iconPath: '/static/tabbar-icon/my-reservation.png',
selectedIconPath: '/static/tabbar-icon/my-reservation-actived.png',

}
] // 导航栏列表
};
},
mounted() {
this.curItem = this.currPage; // 当前所选导航栏
// #ifdef H5
uni.hideTabBar(); // 隐藏 tabBar 导航栏
// #endif
this.curItem = this.currPage; // 当前所选导航栏
},
methods: {
/* 导航栏切换 */
changeItem(e) {
console.log('切换tab', e.pagePath)
// #ifdef MP-WEIXIN
uni.switchTab({
url: e.pagePath,
fail: function(error) {
console.error("Failed to navigate:", error);
}
}); // 跳转到其他 tab 页面
// #endif
// #ifdef MP-ALIPAY
uni.switchTab({
url: e.pagePath,
fail: function(error) {
console.error("Failed to navigate:", error);
}
}); // 跳转到其他 tab 页面
// #endif
}
}
};
</script>
<style lang="scss" scoped>
$textDefaultColor: #999; // 文字默认颜色
$bottomBg: #fff; // 底部背景
$textSelectedColor: #E51717; // 文字选中颜色
$centerItemBg: #fff; // 中间凸起按钮背景
.tabbar-container {

}
}
</style>
4. 隐藏原生tabbar
App.vue
onLaunch: function() {
console.log('App Launch')
// #ifdef MP-ALIPAY
uni.hideTabBar()
// #endif
// #ifdef MP-WEIXIN
uni.hideTabBar()
// #endif
},
5. 全局注册组件
main.js
import Vue from 'vue'
import './uni.promisify.adaptor'

<template>
<view class="common-containter">

<custom-tabbar :curr-page="3" />
</view>
</template>
<script>
export default {
data() {
return {
