课程讲师: CRMEB
课程内容:
1、首先创建拼团秒杀组件promotion.vue
<template>
<view class="promotion">
<view class="promotion-container">
<view class="left">
<navigator :url="list.imgList.list[0].info[3]" hover-class="none">
<image :src="list.imgList.list[0].img" mode=""></image>
</navigator>
</view>
<view class="right">
<navigator :url="list.imgList.list[1].info[3]" hover-class="none">
<image :src="list.imgList.list[1].img" mode=""></image>
</navigator>
<navigator :url="list.imgList.list[2].info[3]" hover-class="none">
<image :src="list.imgList.list[2].img" mode=""></image>
</navigator>
</view>
</view>
</view>
</template>
<script>
export default {
props: {
list: {
type: Object,
default: () => {}
}
}
}
</script>
<style lang="scss" scoped>
.promotion {
&-container {
display: flex;
height: 260rpx;
padding: 30rpx;
justify-content: space-between;
}
.left {
image {
width: 260rpx;
height: 260rpx;
}
}
.right {
display: flex;
flex-direction: column;
justify-content: ;
image {
width: 416rpx;
height: 124rpx;
}
}
}
</style>
2、在index.vue中应用,再在comments 中注册,在template中使用,并获取数据
<template>
<view class="home">
<view class="home-container">
<Banner :list='swiperData'></Banner>
<SubCategory :list='menusData'></SubCategory>
<Promotion :list="promotionData"></Promotion>
</view>
</view>
</template>
<script>
import Banner from './components/Banner.vue'
import SubCategory from '/components/SubCategory.vue';
import Promotion from 'components/Promotion.vue'
export default {
comments:{
Banner,
SubCategory,
Promotion
},
data(){
return {
swiperData:{},
menusData:{},
promotionData
}
},
onLoad() {
this._getHomeData()
},
methods:{
async _getHomeData(){
const {status,data,msg} = await homeDataApi()
if(status === this.API_STATUS_CODE.SUCCESS){
console.log(status,data,msg)
this.swiperData = data.swiperBg.default
this.menusData = data.menus.default
this.promotionData = data.activity.default
app._initTabBar(data.tabBar.default)
}else{
uni.showToast({
icon:'none',
title:'首页数据获取失败,请刷新重试',
duration:3000
})
}
}
}
}
</script>
<style>
</style>
课程收获:
这节课主要学习到了直接在template跳转的方式navigator,该组件类似HTML中的组件,但只能跳转本地页面,常用的参与有url (应用内的跳转链接,值为相对路径或绝对路径)open-type(navigate:对应 uni.navigateTo 的功能,redirect:对应 uni.redirectTo 的功能,switchTab: 对应 uni.switchTab 的功能,reLaunch: 对应 uni.reLaunch 的功能,navigateBack:对应 uni.navigateBack 的功能,exit),hover-class(指定点击时的样式类,当hover-class="none"时,没有点击态效果 )
