欢迎fork与star
1 项目效果及环境准备
1.1 项目效果
本文主要使用uniapp实现一个简单的app应用
1.2 环境准备&项目初始化
①node环境：去node.js官网下载稳定版的node即可，下载之后配置环境变量，通过
node -v查看是否配置成功
② 开发工具选择：HBuilder-X
官网下载地址：https://uniapp.dcloud.net.cn/quickstart.html#
根据自己的操作系统下载对应的环境即可，下载好之后，双击.exe文件打开HBuilderX
点击左上角：文件 - 新建项目 - 选择uni-app项目，填写对应项目名，其他默认即可【这里我采用vue2的语法】
效果：
展示效果选择手机页面方式：
当然我们也可以通过数据线，将手机与电脑连接起来，然后直接在真机上运行。
2 实现tabbar底部导航
增加底部导航，为：首页、分类、学习、我的
官网tabbar教程：https://uniapp.dcloud.net.cn/collocation/pages.html#tabbar
- tabBar 中的 list 是一个数组，只能配置最少2个、最多5个 tab，tab 按数组的顺序排序。
①导入图片资源
导入所给源码中的static下的图片
②新建tabbar目录及对应页面
因为我们整个项目是将底部导航栏中的index默认为首页，因此删除之前pages目录的index整个文件夹，并在pages下新建tabbar目录，然后在tabbar目录下分别新建classify、index、mine、study页面
③修改页面主题颜色，修改App.vue
④配置底部导航栏，修改package.json
- 配置页面
在pages配置下，修改页面配置，包括修改页面路径及是否允许下拉刷新等
{
"pages": [ //pages数组中第一项表示应用启动页，参考：https://uniapp.dcloud.io/collocation/pages
{
//指定有哪些页面，并配置样式
"path" : "pages/tabbar/index/index",
"style" :
{
//页面顶部的文本
"navigationBarTitleText":"首页",
"navigationStyle":"custom"
}
}
,{
"path" : "pages/tabbar/classify/classify",
"style" :
{
"navigationBarTitleText":"分类",
"navigationBarBackgroundColor":"#00b783",
"navigationBarTextStyle":"white",
//不启动下拉刷新
"enablePullDownRefresh":false
}
}
,{
"path" : "pages/tabbar/study/study",
"style" :
{
"navigationBarTitleText":"学习中心",
"navigationBarBackgroundColor":"#00b783",
"navigationBarTextStyle":"white",
"enablePullDownRefresh":false
}
}
,{
"path" : "pages/tabbar/mine/mine",
"style" :
{
"navigationBarTitleText":"个人中心",
"navigationBarBackgroundColor":"#00b783",
"navigationBarTextStyle":"white",
"enablePullDownRefresh":false
}
}
],
...
}
- 新增tabbar配置
包括配置文本，选中未选中时候的图标等
{
"pages": [ //pages数组中第一项表示应用启动页，参考：https://uniapp.dcloud.io/collocation/pages
....
// 底部导航栏
"tabBar":{
"color":"#999",
//选中时的颜色
"selectedColor":"#00b783",
"borderStyle":"white",
"backgroundColor":"#FFFFFF",
"list":[
{
//底部导航栏的index对应页面
"pagePath":"pages/tabbar/index/index",
//对应文本
"text":"首页",
//未选中时的图标
"iconPath":"static/tabar1.png",
//选中之后的图标
"selectedIconPath":"static/tabaron1.png"
},
{
"pagePath":"pages/tabbar/classify/classify",
"text":"分类",
"iconPath":"static/tabar2.png",
"selectedIconPath":"static/tabaron2.png"
},
{
"pagePath":"pages/tabbar/study/study",
"text":"学习",
"iconPath":"static/tabar3.png",
"selectedIconPath":"static/tabaron3.png"
},
{
"pagePath":"pages/tabbar/mine/mine",
"text":"我的",
"iconPath":"static/tabar4.png",
"selectedIconPath":"static/tabaron4.png"
}
]
}
}
⑤查看效果
然后重新运行在浏览器，如果显示不出效果，则先暂停，然后重新运行在对应浏览器
效果：
3 实现搜索框（使用第三方组件实现）
①下载第三方组件
组件 - 自定义导航栏-下载组件
选择下载并导入：
注意，下载插件是需要注册账号并登录的，如果没有账号的话，注册并登录即可
导入成功之后的效果：
②安装scss/sass插件
因为我们后续会使用到css中的scss语法，所以需要提前安装插件
工具 - 插件安装
如果已经存在则无需安装
否则，点击安装新插件，插件市场中搜索sass，然后选择下载插件并导入
③抽取nav-bar组件（防止主页面代码过多不易维护）
在components组件下新建navbar目录，然后在navbar目录下创建navbar.vue文件
navbar.vue:
<template>
<view>
<view class="example-body">
<uni-nav-bar shadow statusBar :fixed="false" color="#333333" background-color="#FFFFFF" right-icon="scan">
<view class="input-view">
<uni-icons class="input-uni-icon" type="search" size="22" color="#666666" />
<input confirm-type="search" class="nav-bar-input" type="text" placeholder="输入搜索关键词">
view>
uni-nav-bar>
view>
view>
template>
<script>
import uniNavBar from '@/components/uni-nav-bar/uni-nav-bar.vue'
export default {
data() {
return {
}
},
methods: {
},
components: {
uniNavBar
}
}
script>
<style lang="scss">
.input-view {
/* #ifndef APP-PLUS-NVUE */
display: flex;
/* #endif */
flex-direction: row;
width: 600rpx;
flex: 1;
background-color: #f8f8f8;
height: 30px;
border-radius: 15px;
padding: 0 15px;
flex-wrap: nowrap;
margin: 7px 0;
line-height: 30px;
}
.input-uni-icon {
line-height: 30px;
}
.nav-bar-input {
height: 30px;
line-height: 30px;
/* #ifdef APP-PLUS-NVUE */
width: 370rpx;
/* #endif */
padding: 0 5px;
font-size: 28rpx;
background-color: #f8f8f8;
}
.example-body {
padding: 0;
}
style>
④在pages/tabbar/index/index.vue中引入Navbar组件
<template>
<view>
<Navbar/>
view>
template>
<script>
import Navbar from "../../../components/navbar/navbar.vue"
export default {
data() {
return {
}
},
methods: {
},
components:{
Navbar,
}
}
script>
⑤效果
页面效果：
4 首页实现Banner轮播图
通过网络请求动态获取图片数据
4.1 通过网络请求获取数据
①uni.request发起网络请求
pages/tabbar/index/index.vue：
<script>
import Navbar from "../../../components/navbar/navbar.vue"
export default {
data() {
return {
//多张图片，用数组存放
topBanner: [],
}
},
methods: {
},
mounted(){
//vue的生命周期函数
uni.request({
url: "http://html5.bjsxt.cn/api/index/banner",
//注意：网络请求必须要按照下面的方式发起，不能使用新语法等
success: (res) => {
// console.log(res)
this.topBanner = res.data.top_banner
}
})
},
components:{
Navbar,
}
}
script>
②通过console.log打印网络请求所返回的数据：
③根据网络返回的结果获取图片
需要根据自己的手机型号进行样式的调整
pages/tabbar/index/index.vue：
<template>
<view class="home">
<Navbar/>
<view class="index_banner_box">
<swiper class="swiper" :indicator-dots="true" :autoplay="true" :interval="3000" :duration="500">
<swiper-item v-for="(item, index) in topBanner" :key="index">
<image class="banner" :src="item.img_url" mode="">image>
swiper-item>
swiper>
view>
view>
template>
<script>
...
script>
<style lang="scss">
.home {
//flex：盒子模型
display: flex;
flex-direction: column;
flex: 1;
overflow: hidden;
.index_banner_box {
display: flex;
width: 100%;
padding: 10px;
justify-content: center;
align-items: center;
border-radius: 5px;
overflow: hidden;
.swiper{
width: 100%;
height: 260rpx;
.banner{
width: 700rpx;
height: 260rpx;
}
}
}
}
style>
4.2 在页面中展示图片数据并配置样式
4.3 结果
5 实现课程导航
注意：import用于在js中引入css文件， @import用于在css中引入css文件
5.1 抽取课程导航coursenav为component，并编写页面
①引入源码中common下的图标样式，css文件等
②在components文件夹下新建coursenav
coursenav.vue:
<template>
<view class="course_nav_con">
<view class="course_nav_info" v-for="(item, index) in list" :key="index">
<text class="course_nav_icon icon iconfont" :class="item.icon">text>
<view class="course_info_text">{{item.text}}view>
view>
view>
template>
<script>
export default {
data() {
return {
list: []
}
},
mounted() {
uni.request({
url: "http://html5.bjsxt.cn/api/index/nav",
success: (res) => {
this.list = res.data.data
}
})
},
methods: {
}
}
script>
<style lang="scss">
// import用于在js中引入css文件， @import用于在css中引入css文件
@import "@/common/font/iconfont.css";
.course_nav_con {
display: flex;
// 盒子模型不撑开容器本身大小
box-sizing: border-box;
flex-direction: row;
flex-wrap: wrap;
padding: 15px 10px;
.course_nav_info {
width: 20%;
flex-direction: row;
flex-wrap: wrap;
text-align: center;
margin-bottom: 15px;
.course_nav_icon {
font-size: 30px;
}
.icon-java {
color: #2a83fe;
}
.icon-weifuwu {
color: #fd3761;
}
.icon-zuzhijiagou {
color: #2b91e2;
}
.icon-dashuju {
color: #2a83fe;
}
.icon-h {
color: #00b478;
}
.icon-icon-- {
color: #fd6012;
}
.icon-rengongzhineng {
color: #fe391f;
}
.icon-ruanjianceshi {
color: #00b478;
}
.icon-huatong {
color: #fea917;
}
.icon-bianchengshibaobiao_icon {
color: #2a83fe;
}
.icon-jianmo {
color: #00b478;
}
.icon-chuangye {
color: #fe391f;
}
.course_info_text {
width: 100%;
font-size: 13px;
margin-top: 10px;
white-space: nowrap;
text-overflow: ellipsis;
overflow: hidden;
}
}
}
style>
5.2 主页导入课程
在pages/tabbar/index/index.vue中引入CourseNar
- import CourseNav from “…/…/…/components/coursenav/coursenav.vue”
- components中添加CourseNav,
- template标签中添加
<template>
<view class="home">
<Navbar/>
<view class="index_banner_box">
<swiper class="swiper" :indicator-dots="true" :autoplay="true" :interval="3000" :duration="500">
<swiper-item v-for="(item, index) in topBanner" :key="index">
<image class="banner" :src="item.img_url" mode="">image>
swiper-item>
swiper>

<CourseNav/>
view>
template>
<script>
import Navbar from "../../../components/navbar/navbar.vue"
import CourseNav from "../../../components/coursenav/coursenav.vue"
export default {
data() {
return {
//多张图片，用数组存放
topBanner: [],
}
},
methods: {
},
mounted(){
//vue的生命周期函数
uni.request({
url: "http://html5.bjsxt.cn/api/index/banner",
//注意：网络请求必须要按照下面的方式发起，不能使用新语法等
success: (res) => {
// console.log(res)
this.topBanner = res.data.top_banner
}
})
},
components:{
Navbar,
CourseNav,
}
}
script>
5.3 效果
部分网络上的css及图标样式已经获取不到了，所以大家可以替换新的网络地址来获取对应的图标
6 实现限时免费
6.1 创建free-card的components
新建free-card目录，然后新建free-card.vue文件
<template>
<view>
<view class="free_card_box" v-for="(item, index) in teaList" :key="index">
<view class="free_card_img">
<image :src="item.teacher_logo" mode="">image>
view>
<view class="free_card_txt">
<view class="free_card_T">{{ item.limitName }}view>
<view class="free_card_info">
<view class="free_card_info_txt">
<view class="info_txt1">{{ item.teacher_name }}{{ item.teacher_job }}view>
<view>{{ item.limitNum }}人学过view>
view>
<view class="free_card_info_btn" v-if="item.baoming == '马上报名'">{{ item.baoming }}view>
<view class="free_card_info_btn free_card_info_btn1" v-else>{{ item.baoming }}view>
view>

template>
<script>
export default {
name:"free-card",
data() {
return {
teaList:[]
}
},
mounted(){
uni.request({

font-size: 16px;
margin-top: 10px;
}
.free_card_info_btn1{
background-color: #ddd;
}
}
}
}
style>
6.2 首页引入free-card
- 在script标签中导入
- 在component中导入
- 在页面中引用
修改pages/tabbar/index/index.vue
①在课程导航栏下方添加FreeCard组件及在线课程图标
<CourseNav/>
<view class="online_box">
<image :src="index_banner.img_url" class="online_img">image>
view>
<view class="free_box">
<view class="free_T_box public_tow_box">
<view class="public_T">
限时免费
view>
view>
<FreeCard />
view>
②在script中获取图片和文本数据，并引入FreeCard组件
<script>
import Navbar from "../../../components/navbar/navbar.vue"
import CourseNav from "../../../components/coursenav/coursenav.vue"
import FreeCard from "../../../components/free-card/free-card.vue"
export default {
data() {
return {
//多张图片，用数组存放
topBanner: [],
index_banner:{},
}
},
methods: {
},
mounted(){
//vue的生命周期函数
uni.request({
url: "http://html5.bjsxt.cn/api/index/banner",
//注意：网络请求必须要按照下面的方式发起，不能使用新语法等
success: (res) => {
// console.log(res)
this.topBanner = res.data.top_banner
this.index_banner = res.data.index_banner
}
})
},
components:{
Navbar,
CourseNav,
FreeCard, //引入限时免费组件
}
}
script>
③在style中新增css样式
6.4 效果
7 实现就业班模块
view标签与div标签区别：
- view标签通常具有更丰富的功能，比如数据绑定、事件处理等。而div标签只是一个简单的容器，没有特定的功能。
7.1 创建jobScroll

methods: {
clickViode(){
uni.navigateTo({
// 跳转视频播放页面
url:"/pages/course/video/video"
})
}
}
}
script>
10.3 效果
bug
如果运行项目发现报错：‘core-js/modules/es.string.iterator.js’
- 则表明缺少
core-js环境，在终端cmd执行下面命令
# 安装core-js之后，重新启动项目
npm i core-js -D
11 打包发布项目
11.1 app打包
①在manifest.json中配置AppID、图标等，如果没有AppID则重新获取
②选择应用顶部的发行 - 云打包 - 填写对应信息（证书等）
11.2 小程序打包
以微信小程序为例
①下载微信开发者工具，并开放端口供uniapp调用（设置-安全-打开服务端口）
②从uniapp直接跳转到微信开发者工具
③接下来的发布就和小程序发布一样了
详情参考：https://blog.csdn.net/weixin_45565886/article/details/130918238
填写AppId等
