@描述:自定义底部导航栏
@使用:
在main.js全部引入:
import tabBar from "@/pages/common/"
Vue.component('tabBar', tabBar)
在需要显示的页面底部添加:
<view>
<view>这里是页面内容代码区域</view> // 其中uni-p-b-98是公共样式类名,表示padding-bottom: 98upx; 设置的98upx是和底部导航栏的高度保持一致,页面的内容就不会被底部导航遮挡住啦
<view class="uni-p-b-98"></view> // 最后引入自定义组件,并传当前栏目对应的pagePath到自定义组件,显示当前栏目的选中样式
<tabBar :pagePath="'/pages/tabBar/home/home'"></tabBar>
</view>
-->
<template>
<view class="uni-tabbar">
<view class="uni-tabbar__item" v-for="(item,index) in tabbar" :key="index" @tap="changeTab(item)">
<view class="icon" :class="[ , == pagePath?'uni-active':'']"></view>
<!-- 上面使用的是字体图标,解决切换页面的时候图标会闪的效果,毕竟每切换一个页面都会闪一下不太好看,可以切换使用下面的图片方式 -->
<view v-if="false" class="uni-tabbar__bd">
<view class="uni-tabbar__icon">
<image v-if=" == pagePath" class="uni-w-42 uni-h-42" mode="aspectFit" :src=""></image>
<image v-else class="uni-w-42 uni-h-42" mode="aspectFit" :src=""></image>
</view>
</view>
<view class="uni-tabbar__label" :class="{'active': == pagePath}">
{{}}
</view>
</view>
</view>
</template>
