创建uni项目什么的就不说啦,这里直接进入正题~
1.新建一个与 pages同级的文件夹目录 components ,用来放置我们的tabbar文件:
2.编写自定义tabbar.vue
- <template>
- <view class="tabbar-container">
- <block style="margin-top: 200rpx;">
- <view class="tabbar-item" v-for="(item, index) in tabbarList"
- :class="[item.centerItem ? ' center-item' : '']" @click="changeItem(item)">
- <view>
- <view class="item-top">
- <image :src="currentItem == item.id ? item.selectIcon : item.icon"></image>
- </view>
- </view>
- <view class="item-bottom" :class="[currentItem == item.id ? 'item-active' : '']">
- <text>{{ item.text }}</text>
- </view>
- </view>
- </block>
-
- </view>
- </template>
-
- <script>
- export default {
- props: {
- currentPage: {
- type: Number,
- default: 0
- }
- },
- data() {
- return {
- currentItem: 0,
- tabbarList: [{
- id: 0,
- path: '/pages/index/index',
- icon: '../../static/iconsvg/home-no.svg',
- selectIcon: "../../static/iconsvg/home.svg",
- text: '首页',
- centerItem: false
- },
- {
- id: 1,
- path: '/pages/order/order',
- icon: '../../static/iconsvg/dating-no.svg',
- selectIcon: '../../static/iconsvg/dating.svg',
- text: '服务大厅',
- centerItem: false
- },
- {
- id: 2,
- path: '/pages/upGoodInfo/upGoodInfo',
- icon: '../../static/iconsvg/fabu.svg',
- selectIcon: '../../static/iconsvg/fabu.svg',
- text: '发布',
- centerItem: true
- },
- {
- id: 3,
- path: '/pages/connection/connection',
- icon: '../../static/iconsvg/txl-no.svg',
- selectIcon: '../../static/iconsvg/txl.svg',
- text: '通讯录',
- centerItem: false
- },
- {
- id: 4,
- path: '/pages/person/person',
- icon: '../../static/iconsvg/my-no.svg',
- selectIcon: '../../static/iconsvg/my.svg',
- text: '我的',
- centerItem: false
- }
- ]
- };
- },
- mounted() {
- this.currentItem = this.currentPage;
- uni.hideTabBar();
- },
- methods: {
- changeItem(item) {
- let _this = this;
- console.log(item.path)
- if (item.id == 2) {
- uni.reLaunch({
- url: item.path
- })
- }
- uni.reLaunch({
- url: item.path
- });
-
- }
- }
- };
- </script>
- <style scoped>
- view {
- padding: 0;
- margin: 0;
- box-sizing: border-box;
- background-color: #fff;
- }
-
- .tabbar-container {
- position: fixed;
- bottom: 0;
- left: 0;
- width: 100%;
- height: 146rpx;
- box-shadow: 0 0 5px #999;
- display: flex;
- align-items: flex-start;
- padding: 5rpx 0;
- color: #999999;
- }
-
- .tabbar-container .tabbar-item {
- width: 20%;
- height: 100rpx;
- display: flex;
- flex-direction: column;
- justify-content: center;
- align-items: center;
- text-align: center;
- }
-
- .tabbar-container .item-active {
- color: #22b9ff;
- }
-
- .tabbar-container .center-item {
- display: block;
- position: relative;
- }
-
- .tabbar-container .tabbar-item .item-top {
- width: 70rpx;
- height: 70rpx;
- padding: 10rpx;
- }
-
- .tabbar-container .center-item .item-top {
- flex-shrink: 0;
- width: 100rpx;
- height: 100rpx;
- position: absolute;
- top: -50rpx;
- left: calc(50% - 50rpx);
- border-radius: 50%;
- box-shadow: 0 0 5px #999;
- }
-
- .tabbar-container .tabbar-item .item-top image {
- width: 100%;
- height: 100%;
- }
-
- .tabbar-container .tabbar-item .item-bottom {
- font-size: 28rpx;
- width: 100%;
- }
-
- .tabbar-container .center-item .item-bottom {
- position: absolute;
- bottom: 5rpx;
- }
- </style>
注意 :icon 和 selectIcon 的图标地址不要引用错哦
3.找到我们的入口文件 main.js ,引用写好的tabbar
- import tabbar from "components/tabbar/tabbar.vue"
- Vue.component('tabbar',tabbar)
注意 : 要写在 import Vue from 'vue' 之后哦
4.在每个tabbar页面的 template 的最后一行加上tabbar组件
注意 : 这里的tabbar组件名需和在 main.js 中注册的一样
:current-page 指的是当前页面的id索引值,比如,如果是首页的话,:current-page="0"
这样,我们的自定义tabbar就设置完成啦!
