微信小程序开发(4) 企业展示-阿里云开发者社区

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企业内部宣传展示等功能。

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: 'fangbei'
})

2. 小程序公共设置

主要注册五个页面，设置窗口，以及显示在tabbar中显示三个页面

{
  "pages": [
    "pages/index/index",
    "pages/news/news",
    "pages/news/news-details",
    "pages/product/product",
    "pages/contact/contact"
  ],
  "window": {
    "navigationBarTextStyle": "black",
    "navigationBarTitleText": "盛世华安",
    "navigationBarBackgroundColor": "#fbf9fe",
    "backgroundColor": "#fbf9fe"
  },
  "tabBar": {
    "color": "#dddddd",
    "selectedColor": "#459ae9",
    "borderStyle": "black",
    "backgroundColor": "#ffffff",
    "list": [{
      "pagePath": "pages/index/index",
      "iconPath": "images/index.png",
      "selectedIconPath": "images/index_selected.png",
      "text": "公司盛况"
    }, {
      "pagePath": "pages/product/product",
      "iconPath": "images/product.png",
      "selectedIconPath": "images/product_selected.png",
      "text": "产品服务"
    }, {
      "pagePath": "pages/contact/contact",
      "iconPath": "images/contact.png",
      "selectedIconPath": "images/contact_selected.png",
      "text": "联系我们"
    }]
  },
  "networkTimeout": {
    "request": 10000,
    "connectSocket": 10000,
    "uploadFile": 10000,
    "downloadFile": 10000
  },
  "debug": true
}

3. 公用样式表

二、业务页面部分

小程序页面主要由以下文件组成。

本项目程序分为4个页面：主页、新闻详情页、产品服务页、联系我们页。

主页部分

主页效果图如下

1. 页面结构

上方是一个图片轮播图，中间是新闻列表，下文有一个查看更多导航

其页面结构代码如下

<!--index.wxml-->
<view class="index">
    <view class="slider">
        <swiper class="swiper" indicator-dots="{{indicatorDots}}"
  autoplay="{{autoplay}}" interval="{{interval}}" duration="{{duration}}">
            <block wx:for="{{swipers}}">
                <swiper-item>
                    <navigator url="/pages/news/news-details?id={{item.id}}" class="widget">
                        <image mode="widthFix" src="{{item.thumbnail_images.medium_large.url}}" class="slide-image" width="" height=""></image>
                    </navigator>
                </swiper-item>
            </block>
        </swiper>
    </view>
    <view class="news">
        <text class="news-title">新闻动态</text>

        <block wx:for="{{news}}">
        <navigator url="/pages/news/news-details?id={{item.id}}">
        <view class="news-item line">
            <view class="news-item-pic">
                <image mode="widthFix" src="{{item.thumbnail}}" class="news-item-image" width="" height=""></image>
            </view>
            <view class="news-item-words">
                <view class="news-item-title"><text>{{item.title_plain}}</text></view>
                <view class="news-item-content"><text>{{item.excerpt_plain}}</text></view>
            </view>
        </view>
        </navigator>
        </block>

        <view class="widgets__list widgets__list_show">
            <navigator url="/pages/news/news?cat={{cat}}" class="widget_more">
                <text class="news-more">查看更多</text>
                <image class="widget__arrow" src="/images/arrowright.png" mode="aspectFill" />
                <view class="widget__line widget__line_first"></view>
            </navigator>
        </view>
    </view>
</view>

2. 样式表

样式代码如下所示

.index{
    background-color: #FBF9FE;
    font-family: -apple-system-font,Helvetica Neue,Helvetica,sans-serif;
    flex: 1;
    min-height: 100%;
    font-size: 32rpx;
}
.head{
    padding: 80rpx;
    line-height: 1;
}
.body{
    padding-left: 30rpx;
    padding-right: 30rpx;
    overflow: hidden;
}
.title{
    font-size: 52rpx;
}
.desc{
    margin-top: 10rpx;
    color: #888888;
    font-size: 28rpx;
}

.widgets__item{
    margin-top: 20rpx;
    margin-bottom: 20rpx;
    background-color: #FFFFFF;
    overflow: hidden;
    border-radius: 4rpx;
    cursor: pointer;
}
.widgets__info{
    display: flex;
    padding: 40rpx;
    align-items: center;
    flex-direction: row;
}
.widgets__info_show{
}
.widgets__info_show .widgets__info-img{
    transform: rotate(-90deg);
}
.widgets__info-name{
    flex: 1;
}
.widgets__info-img{
    width: 32rpx;
    height: 32rpx;
    transition: transform .4s;
    transform: rotate(90deg);
}

.widgets__list{
    display: none;
}
.widgets__list_show{
    display: block;
}
.widget{
    position: relative;
    padding-top: 26rpx;
    padding-bottom: 26rpx;
    padding-left: 40rpx;
    padding-right: 40rpx;
}
.widget_more{
    position: relative;
    padding-top: 26rpx;
    padding-bottom: 26rpx;
    padding-left: 0rpx;
    padding-right: 40rpx;
}
.widget__arrow{
    position: absolute;
    top: 28rpx;
    right: 44rpx;
    width: 32rpx;
    height: 32rpx;
}
.widget__line{
    content: " ";
    position: absolute;
    left: 40rpx;
    top: 0;
    right: 0;
    height: 2rpx;
    background-color: #F0F0F0;
}
.widget__line_first{
    left: 0;
    right: 0;
    background-color: #D8D8D8;
}

3、页面逻辑处理

页面逻辑也是通过接口取网站的数据，并且存到swipet,news等数据中，供前端显示

var CONFIG = require('../../utils/config.js')

Page({
  data: {
    indicatorDots: true,
    autoplay: true,
    interval: 5000,
    duration: 1000,
    swipers: [],
    news: [],
    cat: '17',
  },

  onLoad: function () {
    var that = this;
    wx.request({
      url: CONFIG.API_URL.GET_INDEX,
      method: 'GET',
      data: {},
      header: {
        'Accept': 'application/json'
      },
      success: function(res) {
        console.log(res);

        if (res.statusCode == 200 && res.data.status == 'ok') {
          var data = res.data;
          var swipers = [];
          var news = [];
          
          console.log(data);
          for (var i = 0; i < data.count; i++) {
            if (i < 3) {
              swipers.push(data.posts[i]);
            }
            else {
              var excerpt_plain = data.posts[i].excerpt.replace(/<[^>].*?>/g, "");
              data.posts[i].excerpt_plain = excerpt_plain.replace(/\[[^\]].*?\]/g, "");
              news.push(data.posts[i]);
            }
          }
          that.setData({swipers: swipers});
          that.setData({news: news});
        } else {
          
        }
      }
    })
  },
  onShareAppMessage: function () {
   // return custom share data when user share.
   console.log('onShareAppMessage')
   return {
      title: '盛世华安',
      desc: '小程序',
      path: '/pages/index/index'
    }
  },
});

产品服务页部分

产品服务页和主页的新闻列表页类似

1. 页面结构

其页面结构代码如下

<view class="news">
        <text class="news-title">产品服务</text>

        <block wx:for="{{news}}">
        <navigator url="/pages/news/news-details?id={{item.id}}">
        <view class="news-item line">
            <view class="news-item-pic">
                <image mode="widthFix" src="{{item.thumbnail}}" class="news-item-image" width="" height=""></image>
            </view>
            <view class="news-item-words">
                <view class="news-item-title"><text>{{item.title_plain}}</text></view>
                <view class="news-item-content"><text>{{item.excerpt_plain}}</text></view>
            </view>
        </view>
        </navigator>
        </block>
    </view>

2. 样式表

使用公共样式表。

3、页面逻辑处理

请求官网接口数据并显示

var CONFIG = require('../../utils/config.js')

Page({
  data: {
  },
  onLoad: function () {
    var that = this;
    wx.request({
      url: CONFIG.API_URL.GET_CATEGORY + '14',
      method: 'GET',
      data: {},
      header: {
        'Accept': 'application/json'
      },
      success: function(res) {
        console.log(res);

        if (res.statusCode == 200 && res.data.status == 'ok') {
          var data = res.data;
          var news = [];
          
          console.log(data);
          for (var i = 0; i < data.count; i++) {
            var excerpt_plain = data.posts[i].excerpt.replace(/<[^>].*?>/g, "");
            data.posts[i].excerpt_plain = excerpt_plain.replace(/\[[^\]].*?\]/g, "");
            news.push(data.posts[i]);
          }
          that.setData({news: news});
        } else {
          
        }
      }
    })
  },
  onReady:function(){
    // 页面渲染完成
  },
  onShow:function(){
    // 页面显示
  },
  onHide:function(){
    // 页面隐藏
  },
  onUnload:function(){
    // 页面关闭
  },
  go: function(event) {
    wx.navigateTo({
      url: '/pages/news/news-details?id=' + event.currentTarget.dataset.type
    })
  }
})

          var data = res.data;
          
          that.setData({page: data.page});
          WxParse.wxParse('content', 'html', data.page.content, that, 25)
        } else {
