对于微信App, 导航用的是非常多的,几乎每个页面都需要,我们先将它简单地封装以下。
1. free-icon组件, 用来定义每个icon图标
<template> <view :style="getSize" class="flex justify-center align-center"> <text class="iconfont font-md"></text> </view> </template> <script> export default { props: { size: { type: [Number, String], default: 90 }, icon: { type: String, default: "", } }, computed:{ getSize() { return `height: ${this.size}rpx; width: ${this.size}rpx;` } } } </script>
2. h-nav-bar导航组件:
<template> <view> <!-- 导航栏 --> <view class="bg-light" :class="fixed ? ‘position-fixed fixed-top‘ : ‘‘"> <view> <!-- 状态栏 --> <view :style="‘height:‘ + statusBarHeight + ‘px‘"></view> <!-- 导航 --> <view class="flex justify-between w-100 align-center border" style="height: 90rpx;"> <view class="ml-3" v-if="title">{{title}}</view> <view class="flex"> <free-icon :size="90" :icon="‘\ue62c‘"></free-icon> <free-icon :size="90" :icon="‘\ue621‘"></free-icon> </view> </view> </view> </view> <!-- 占位 --> <view :style="fixedStyle" v-if="fixed"></view> </view> </template> <script> import freeIcon from ‘@/components/free-ui/free-icon.vue‘ export default { props: { title: { type: [String, Boolean], default: "" }, //是否fixed定位到顶部 fixed: { type: Boolean, default: true } }, components: { freeIcon }, data() { return { // 状态栏 statusBarHeight: 0, navBarHeight: 0 } }, mounted() { // #ifdef APP-PLUS-NVUE this.statusBarHeight = plus.navigator.getStatusbarHeight() console.log(this.statusBarHeight) // #endif this.navBarHeight = this.statusBarHeight + uni.upx2px(90) }, methods: { }, computed: { fixedStyle() { return `height: ${this.navBarHeight}px;` } } } </script>
3. 在index.nvue中调用即可
<template> <view> <h-nav-bar :title="‘友我‘" :fixed="true"></h-nav-bar> </view> </template> <script> import hNavBar from ‘@/components/free-ui/h-nav-bar.vue‘ export default { components: { hNavBar } } </script>
导航组件中需要注意的点:
1. 需要计算app端的状态栏高度
2. 当我们将导航fixed定位到顶部时,需要创建一个占位view,否则就会有一部分内容会被遮挡
最终效果如下:
