本文实例为大家分享了微信小程序底部导航栏组件的具体实现代码,供大家参考,具体内容如下 1、在自己项目的公共组件的文件价下新建tabbar.vue(定义的自定义导航栏组件) <template> <view v-if="showTabbar" class="tabbar"> <view v-for="(item, index) in tabList" :key="index" class="icon" @click="switchTabBar(item.path, index)" > <image :src="index == current ? item.iconActivePath : item.iconPath"></image> <text :class="index == current ? 'active_text' : 'text'" bindtap = 'go'>{{ item.name }}</text> </view> </view> </template> <script> // import container from '@/channelMessage/get-container' export default { props: { showTabbar: { type: Boolean, default: true, }, current:{ // 当前页面index type:Number, default:0 }, }, data() { return { selectedIndex: 0, tabList: [ { name: "首页", iconPath: require("../../../static/image/img/tab-home-nor.png"), iconActivePath: require("../../../static/image/img/tab-home-sel.png"), path: "/pages/index/index", }, { name: "购物车", iconPath: require("../../../static/image/img/tab-cart-nor.png"), iconActivePath: require("../../../static/image/img/tab-cart-sel.png"), path: "/pages/cart/cartEdit", }, { name: "我的", iconPath: require("../../../static/image/img/tab-my-nor.png"), iconActivePath: require("../../../static/image/img/tab-my-sel.png"), path: "/pages/mine/mine", }, ], } }, onShow() { // const containerId = container.getContainerId() // if (containerId == '1000') { // this.showTabbar = false // } }, methods: { switchTabBar(path, index) { this.item_index = index wx.switchTab({ url: path, }) // this.$router.replace(path) }, }, } </script> <style lang="scss" scoped> .tabbar { position: fixed; bottom: 0; z-index: 10; display: flex; align-items: center; justify-content: space-around; width: 100%; height: 100rpx; background-color: #ffffff; padding-bottom: constant(safe-area-inset-bottom); padding-bottom: env(safe-area-inset-bottom); .icon { display: flex; flex-direction: column; align-items: center; image { width: 50rpx; height: 50rpx; } } .active_text{ font-size: 20rpx; margin-top: 5rpx; color: #d81e06; } .text{ font-size: 20rpx; margin-top: 5rpx; } } </style> 2、在项目中的pages.json文件中新增代码,保证tabbar.vue中的wx.switchTab可以正常使用,代码如下: "tabBar": { "selectedColor": "#EE2F51", "list": [{ "pagePath": "pages/index/index", "text": "首页", "iconPath": "static/image/img/tab-home-nor.png", "selectedIconPath": "static/image/img/tab-home-sel.png" },{ "pagePath": "pages/cart/cartEdit", "text": "购物车", "iconPath": "static/image/img/tab-cart-nor.png", "selectedIconPath": "static/image/img/tab-cart-sel.png" },{ "pagePath": "pages/mine/mine", "text": "我的", "iconPath": "static/image/img/tab-my-nor.png", "selectedIconPath": "static/image/img/tab-my-sel.png" }] }, 3、在main.js中全局注册自定义组件 import tabBar from "./customComponents/commonComponents/tabBar/index.vue"; //换自己的组件位置,这里的index.vue就是前面所说的tabbar.vue Vue.component("tabBar", tabBar); 4、在需要使用导航栏的页面引入注册的组件 //为页面引入导航栏组件 <tabBar :current=item_index></tabBar> //标记状态,是的导航栏可以根据页面显示不同的激活状态 data() { return { item_index: 0, } } //隐藏微信自带的导航栏 onLoad() { wx.hideTabBar(); }, 5、展示效果 以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持极客世界。 |
