環(huán)境搭建和創(chuàng)建項目

開發(fā)環(huán)境搭建

• 使用HubilderX
• 安裝對應插件

創(chuàng)建uniapp項目

• 創(chuàng)建項目（名稱：社區(qū)交友）
• 真機調(diào)試或微信開發(fā)者工具調(diào)試

App.vue引入全局公共樣式

引入官方css樣式庫

• 新建模板項目hello uniapp

• 復制模板common下的css

• 在本項目的app.vue進行引入css文件 @import “./common/uni.css ” (還要引入uni.tff文件，否則報錯)

引入自定義圖標

• 阿里巴巴矢量圖標庫 https://www.iconfont.cn/

• 下載所選圖標至項目打包 得到壓縮文件

• 修改icon.css文件去掉url，引入文件 測試圖標使用

  <view><text class="iconfont icon-smile" style="font-size: 100rpx; color: red;"></text> </view>

引入css動畫庫

• 下載animate.css

• 引入animate.css

• 測試css動畫庫的使用

  <view style="display: flex;justify-content: center;padding: 50rpx;"> <view class="" hover-class=" animated rubberBand" style="border: 1rpx solid black; padding: 20rpx;">點擊效果</view></view>

設置全局屬性globalStyle

• 解析page.json文件 看官方文檔

• 設置導航欄的樣式

  "globalStyle": {"navigationBarTextStyle": "black", //導航欄字體顏色"navigationBarTitleText": "社區(qū)交友",//導航欄文字"navigationBarBackgroundColor": "#FFF",//背景顏色"backgroundColor": "#FFF"}

底部導航開發(fā)

• 設置圖標（圖片為png，81*81）用矢量圖標庫下載

• 配置tabBar前提要配置pages數(shù)組頁面

  "pages": [ //pages數(shù)組中第一項表示應用啟動頁，參考：https://uniapp.dcloud.io/collocation/pages{"path": "pages/index/index","style": {}},{"path" : "pages/news/news","style" : {"navigationBarTitleText": "","enablePullDownRefresh": false}},{"path" : "pages/msg/msg","style" : {"navigationBarTitleText": "","enablePullDownRefresh": false}},{"path" : "pages/my/my","style" : {"navigationBarTitleText": "","enablePullDownRefresh": false}}],"tabBar": {"color": "#323232","selectedColor": "#FC5C82","backgroundColor": "#FFF","borderStyle": "black","list": [{"pagePath": "pages/index/index","text": "首頁","iconPath": "static/tabbar/index.png","selectedIconPath": "static/tabbar/indexed.png"},{"pagePath": "pages/news/news","text": "動態(tài)","iconPath": "static/tabbar/news.png","selectedIconPath": "static/tabbar/newsed.png"},{"pagePath": "pages/msg/msg","text": "消息","iconPath": "static/tabbar/paper.png","selectedIconPath": "static/tabbar/papered.png"},{"pagePath": "pages/my/my","text": "我的","iconPath": "static/tabbar/home.png","selectedIconPath": "static/tabbar/homeed.png"}]}

uni-app和vuejs基礎快速上手

view和text組件和動畫的使用

• hover-class的測試使用
• text的測試使用
• 兩個內(nèi)置組件的使用可參考官方文檔

uniapp的css3選擇器

• 普通的選擇器 id就用#，class就用.，什么都不加默認全部

• 父級下的子級菜單的選擇器

  .box>view:first-of-type{background-color: red; } .box>view:last-of-type{background-color: pink; } .box>view:nth-child(2){background-color: yellow; }

• 奇偶選擇器

  //奇數(shù)選擇器 .box>view:nth-of-type(odd){background-color: red; } //偶數(shù)選擇器 .box>view:nth-of-type(even){background-color: green; } //偶數(shù)選擇器 .box:nth-of-type(even){background-color: green; }

flex布局快速入手

• display:flex 外層使用，塊內(nèi)元素擠在一行內(nèi)
• justify-content:常用center，水平居中
• align-items：常用center，垂直居中
• felx-direction:改變排序方式，從行轉換成列
• felx-shirink：0 不被壓縮
• flex：1占一份 2占兩份

數(shù)據(jù)渲染

• {{}}獲取data中的數(shù)據(jù)渲染
• @tap觸發(fā)點擊事件

class和style的綁定

• 綁定class用冒號:class
• :class={‘class1’:isActive}
• s:tyle=" {‘color’: Color,‘font-size’:num+‘px’}"

條件渲染

• v-if的使用
• v-show是會渲染只是不顯示
• 一般在template里面用v-if

列表渲染

• v-for
• 官方文檔建議v-for寫在

事件處理器

• @tap點擊事件
• @tap.stop點里面不會觸發(fā)外面的事件

監(jiān)聽屬性

• watch

• 測試

  <template><view><view>{{num}}</view><button @tap="changNum()">按鈕</button></view> </template><script>export default {data() {return {num:0}},watch:{num(val){console.log(val);}},methods: {changNum(){this.num++;}}} </script><style> button{background: blue;display: flex;justify-content: center;align-items: center;font-size: 15px;color: white; } </style>

計算屬性

• 常用于數(shù)據(jù)的格式化

• computed

• 測試運用

  <template><view>{{formatWeight}}</view> </template><script>export default {data() {return {weight:2100}},computed:{formatWeight(){return (this.weight>1000)?this.weight/1000+'kg':this.weight+'g';}}} </script><style></style>

首頁開發(fā)

page.json配置

• 導航欄配置根據(jù)官方文檔配置

  {"path": "pages/index/index","style": {"app-plus": {// 導航欄配置"titleNView":{// 搜索框配置"searchInput":{"align":"center","backgroundColor":"#F5F4F2","borderRadius":"4px","disabled":true,"placeholder":"搜索帖子","placeholderColor":"#6D6C67"},"buttons":[{"color":"#333333","colorPressed":"#FD597C","float":"right","fontSize":"20px","fontSrc":"/static/iconfont.ttf","text":"\ue668"}]}}}}

• 用真機調(diào)試成功，微信開發(fā)者工具旁邊無顯示

圖文列表樣式

• 封裝free.css把常用樣式封裝 如==flex：display；justify-content：center；algin-items：center、

• 引入自定義css庫

• 列表開發(fā)

'頂' : '踩';uni.showToast({title: msg + '成功'})},

滾動tab導航開發(fā)

• 頂部導航選項卡

  <scroll-view class="scroll-row border-bottom" scroll-x="true" :scroll-into-view="scrollInto" scroll-with-animation="true"><view v-for="(item,index) in tabBars" :key="index" class="scroll-row-item px-3 py-2 font-md " :id="'tab'+index":class="tabIndex===index?'text-main font-lg font-weight-bold':''" @click="doTab(index)">{{item.name}}</view></scroll-view>tabIndex:0,scrollInto:'',tabBars:[{name:'首頁'},{name:'體育'},{name:'軍事'},{name:'熱點'},{name:'新聞'},{name:'娛樂'},{name:'電競'},{name:'國際'},{name:'國家'}],doTab(index){this.tabIndex=index;this.scrollInto='tab'+index;}

• 下面容器能做到切換與導航欄一樣，容器也能拉取

  <swiper duration=150 @change="onChange" :current="tabIndex" :style="'height:'+scrollH+'px'"><swiper-item v-for="(item,index) in tabBars" :key="index" ><scroll-view scroll-y="true" :style="'height:'+scrollH+'px'"><view v-for="i in 100">{{i}}</view></scroll-view></swiper-item></swiper>doTab(index){this.tabIndex=index;this.scrollInto='tab'+index;},onChange(e){this.doTab(e.detail.current);}onLoad() {const res = uni.getSystemInfoSync();this.scrollH=res.windowHeight-uni.upx2px(101);console.log(this.scrollH);},

• 列表顯示

  <swiper duration=150 @change="onChange" :current="tabIndex" :style="'height:'+scrollH+'px'"><swiper-item v-for="(item,index) in newList" :key="index" ><scroll-view scroll-y="true" :style="'height:'+scrollH+'px'"><block v-for="(item2,index2) in item.list" :key="index"><commonList :item="item2" :index="index2" @follow="follow()" @doSupport="doSupport()"></commonList><divider></divider></block></scroll-view></swiper-item></swiper>getData(){let arr=[];for (var i = 0; i < this.tabBars.length; i++) {arr.push({list: [{userPic: '/static/common//nothing.png',username: '',newstime: '',isFollow: false,title: '我是標題',titlePic: '/static/demo/datapic/45.jpg',support: {type: 'support',support_count: 1,unsupport_count: 2},comment_count: 1,share_num: 0},{userPic: '/static/common//nothing.png',username: '',newstime: '',isFollow: false,title: '我是標題',titlePic: '',support: {type: 'unsupport',support_count: 2,unsupport_count: 2},comment_count: 1,share_num: 1},{userPic: '/static/common//nothing.png',username: '',newstime: '',isFollow: false,title: '我是標題',titlePic: '',support: {type: '',support_count: 2,unsupport_count: 2},comment_count: 1,share_num: 1}]})};this.newList=arr;},

封裝上拉加載組件

• 優(yōu)化加載判斷

  loadMore(index){let item=this.newList[index];if(!item==='上拉加載更多'){return;}item.loading='加載中...';setTimeout(()=>{item.list=[...item.list,...item.list];item.loading='上拉加載更多';},10000)}

• 封裝load-more.vue 并引入

  <template><view class="py-2 flex justify-center align-center"><view class="text-light-muted">{{loading}}</view></view> </template><script>export default{props:{loading:String}} </script>import loadMore from '@/components/common/load-more';export default {components: {commonList,loadMore}, }
