在这篇微信小程序开发教程中，我们将介绍如何使用微信小程序开发热门电影及预览功能。
本文主要分为两个部分，小程序主体部分及电影主页和详情页页面部分
一、小程序主体部分
一个小程序主体部分由三个文件组成，必须放在项目的根目录，如下：
1. 小程序逻辑
App({ onLaunch: function() { // Do something initial when launch. }, onShow: function() { // Do something when show. }, onHide: function() { // Do something when hide. }, globalData: 'I am global data' })
2. 小程序公共设置
主要注册两个页面，热门电影的主页及详情页
{
"pages":[
"pages/index/index",
"pages/details/details"
],
"window":{
"backgroundTextStyle":"light",
"navigationBarBackgroundColor": "#FF4D64",
"navigationBarTitleText": "热门电影",
"backgroundColor":"#FFF",
"navigationBarTextStyle":"white"
}
}
二、电影页面部分
小程序页面主要由以下文件组成。
本项目程序分为两个页面：主页及详情页。
主页部分
主页效果图如下
1. 页面结构
其页面结构代码如下
<loading hidden="{{loading}}"> 加载中... </loading> <scroll-view class="container img-content" style="height: {{windowHeight}}px; width: {{windowWidth}}px; " scroll-y="true" bindscrolltoupper="pullDownRefresh" bindscrolltolower="pullUpLoad" lower-threshold="800"> <navigator class="list flex-box" wx:for="{{films}}" url="../details/details?title=navigate&id={{item.id}}&titles={{item.nm}}"> <view class="list-img"><image class="img" src="{{item.img}}"></image><image class="list-play" src="../../images/i-play.png"></image></view> <view class="list-main flex-btn"> <view class="list-title list-brief"> <text>{{item.nm}}</text> <test class="i-imax" wx:if="{{item.imax && item['3d']}}" src="../../tests/i-imax.png">3Dimax</test> <test class="i-imax" wx:elif="{{item['3d']}}" src="../../images/i-play.png">3d</test> <test class="i-imax" wx:elif="{{item['imax']}}" src="../../tests/i-star.png">imax</test> <test class="i-imax" wx:else="{{item['imax']}}" src="../../images/i-stars.png">2d</test> </view> <view class="list-size" wx:if="{{!item.preSale}}"><view class="star"><view style="width: {{item.sc * 10}}%" class="stars"></view></view>{{item.sc}}</view> <view class="list-brief" wx:if="{{item.preSale}}"><text class="wish">{{item.wish}}人想看</text>{{item.showInfo}}</view> <view class="list-brief">{{item.scm}}</view> <view class="list-brief">{{item.dir}} {{item.star}}</view> <view class="list-sale"><text wx:if="{{!item.preSale}}" class="sales">购票</text><text wx:if="{{item.preSale}}" class="pre-sale">预售</text></view> </view> </navigator> </scroll-view>
2. 样式表
样式代码如下所示
/**index.wxss**/ .flex-box{ display: flex; } .flex-btn{ flex: 1; } .list{ border-bottom: 1rpx solid #e5e5e5; padding: 30rpx; } .list-img{ width: 130rpx; height: 180rpx; margin-right: 20rpx; position: relative; } .list-img .img{ width: 130rpx; height: 180rpx; } .list-play{ position: absolute; left: 45rpx; top: 70rpx; width: 40rpx; height: 40rpx; } .list-title{ height: 52rpx; } .list-title text{ font-size: 18px; line-height: 52rpx; color: #000; } .i-imax{ width: 52rpx; height: 28rpx; margin-left: 10rpx; } .list-size{ height: 40rpx; font-size: 14px; color: #8a869e; } .list-size .star{ width: 100rpx; height: 20rpx; background: url(../../images/i-star.png) no-repeat; background-size: 100rpx; display: inline-block; margin-right: 10rpx; } .stars{ width: 100rpx; height: 20rpx; background: url(../../images/i-stars.png) no-repeat; background-size: 100rpx; float: left; margin-right: 10rpx; } .list-brief{ font-size: 12px; line-height: 48rpx; color: #666; overflow: hidden; text-overflow: ellipsis; white-space: nowrap; width: 400rpx; } .list-brief .wish{ color: #108ee9; border-right: 1rpx solid #666; padding-right: 10rpx; margin-right: 10rpx; } .list-main{ position: relative; } .list-sale{ position: absolute; right: 10rpx; top: 70rpx; } .list-sale text{ padding: 10rpx 18rpx; border: 1rpx solid #37b7ff; font-size: 14px; color: #37b7ff; border-radius: 6rpx; } .list-sale .pre-sale{ border: 1rpx solid #fea54c; color: #fea54c; }
3、 页面逻辑处理
//index.js Page({ data: { films: [], limit: 6, loading: false, windowHeight: 0, windowWidth: 0 }, onLoad: function () { this.setData({ loading: false }) }, onShow: function(){ var that = this wx.request({ url: 'http://m.maoyan.com/movie/list.json', //仅为示例，并非真实的接口地址 data: { offset: 0, type: 'hot', limit: that.data.limit }, header: { 'Content-Type': 'application/json' }, success: function(res) { console.log(res.data) that.setData({ films: res.data.data.movies, loading: true }) } }) wx.getSystemInfo({ success: (res) => { that.setData({ windowHeight: res.windowHeight, windowWidth: res.windowWidth }) } }) }, pullDownRefresh: function(e) { this.onLoad() }, pullUpLoad: function(e) { var limit = this.data.limit + 6 console.log(limit) this.setData({ limit: limit }) this.onShow() } })
这里使用是的猫眼电影的api
其接口为
http://m.maoyan.com/movie/list.json
返回数据如下所示：

详情页部分
1. 页面结构
页面结构用一个视图显示电影的常用信息，以及一个预览视频的功能。
其页面结构代码如下
<loading hidden="{{loading}}"> 加载中... </loading> <view class="detail flex-box" url=""> <view class="detail-img"><image class="img" src="{{films.MovieDetailModel.img}}"></image><image bindtap="vShow" class="detail-play" src="../../images/i-play.png"></image></view> <view class="detail-main flex-btn"> <view class="detail-title detail-brief"> <text>{{films.MovieDetailModel.nm}}</text> <image class="i-imax" wx:if="{{films.MovieDetailModel.imax}}" src="../../images/i-imax.png"></image> <image class="i-imax" wx:if="{{films.MovieDetailModel.preSale}}" src="../../images/i-imax.png"></image> </view> <view class="detail-brief">{{films.MovieDetailModel.scm}}</view> <view class="detail-brief">{{films.MovieDetailModel.cat}}</view> <view class="detail-brief">{{films.MovieDetailModel.src}} / {{films.MovieDetailModel.dur}}分钟</view> <view class="detail-brief">{{films.MovieDetailModel.rt}}</view> <view class="detail-brief" wx:if="{{films.MovieDetailModel.preSale}}"><text class="wish">{{films.MovieDetailModel.wish}}人想看</text>{{films.MovieDetailModel.showInfo}}</view> <view class="detail-size" wx:if="{{!films.MovieDetailModel.preSale}}"><view class="star"><view style="width: {{films.MovieDetailModel.sc * 10}}%" class="stars"></view></view>{{films.MovieDetailModel.sc}}</view> </view> <image class="bg" src="https://gw.alicdn.com/tps/i4/TB1pa7pJFXXXXX6XFXXwwg20FXX-640-448.png"></image> <video class="{{video}}" autoplay="false" bindended="vHid" src="{{films.MovieDetailModel.vd}}" controls></video> </view> <scroll-view class="details-dra"><view>{{details}}</view></scroll-view> <button type="primary" size="{{primarySize}}" plain="{{plain}}" disabled="{{disabled}}" bindtap="pay">立即购票 </button>
2. 样式表

3、 页面逻辑处理
//index.js Page({ data: { films: [], loading: false, title: '正在热映', video: 'video-hide', datails: '', windowWidth: 0 }, onLoad: function (options) { var id = 'http://m.maoyan.com/movie/' + options.id + '.json' this.setData({ title: options.titles }) var that = this wx.request({ url: id, //仅为示例，并非真实的接口地址 data: { }, header: { 'Content-Type': 'application/json' }, success: function(res) { console.log(res.data) that.setData({ films: res.data.data, loading: true }) var pages = that.data.films.MovieDetailModel.dra pages = pages.replace(/<.*?>/ig,"") that.setData({ details: pages }) console.log(pages) } }) }, onReady: function(){ var that = this wx.setNavigationBarTitle({ title: that.data.title }) wx.getSystemInfo({ success: (res) => { that.setData({ windowHeight: res.windowHeight, windowWidth: res.windowWidth }) } }) }, pay: function(){ console.log('pay'); wx.requestPayment({ 'timeStamp': '', 'nonceStr': '', 'package': '', 'signType': 'MD5', 'paySign': '', 'success':function(res){ console.log('success'); }, 'fail':function(res){ console.log('fail'); } }) }, vShow: function(){ this.setData({ video: 'video-show' }) }, vHid: function(){ this.setData({ video: 'video-hide' }) } })
这里使用是的猫眼电影详情的api
其接口为
http://m.maoyan.com/movie/248683.json
其中248683为电影ID
返回数据如下所示：
