1、底部的tabBar

可设置的属性有color、selectedColor、borderStyle、backgroundColor、list至少2个,最多5个(其属性有pagePath、text、iconPath、selectedIconPath等)

"tabBar": {
    "color":"#dddddd",
    "selectedColor":"#3cc51f",
    "borderStyle":"black",
    "backgroundColor":"#2B2B2B",
    "list": [
      {
        "pagePath": "pages/movie/movie",
        "text": "影院热映",
        "iconPath": "assets/img/dy-1.png",
        "selectedIconPath": "assets/img/dy.png"
      },
      {
        "pagePath": "pages/recommend/recommend",
        "text": "电影推荐",
        "iconPath": "assets/img/tj-1.png",
        "selectedIconPath": "assets/img/tj.png"
      },
      {
        "pagePath": "pages/search/search",
        "text": "查询电影",
        "iconPath": "assets/img/search-1.png",
        "selectedIconPath": "assets/img/search.png"
      }
    ]
  },

效果如下图所示:

 

 

2、 滑块视图容器 swiper

swiper

滑块视图容器。

属性名 类型 默认值 说明 最低版本
indicator-dots Boolean false 是否显示面板指示点  
indicator-color Color rgba(0, 0, 0, .3) 指示点颜色 1.1.0
indicator-active-color Color #000000 当前选中的指示点颜色 1.1.0
autoplay Boolean false 是否自动切换  
current Number 0 当前所在页面的 index  
interval Number 5000 自动切换时间间隔  
duration Number 500 滑动动画时长  
circular Boolean false 是否采用衔接滑动  
vertical Boolean false 滑动方向是否为纵向  
bindchange EventHandle   current 改变时会触发 change 事件,event.detail = {current: current, source: source}

从公共库v1.4.0开始, change 事件返回 detail 中包含一个 source 字段,表示导致变更的原因,可能值如下:

  • autoplay  自动播放导致swiper变化;
  • touch  用户划动引起swiper变化;
  • 其他原因将用空字符串表示。

注意 :其中只可放置  组件,否则会导致未定义的行为。

swiper-item

仅可放置在  组件中,宽高自动设置为100%。

示例代码:

<swiper indicator-dots="{{indicatorDots}}"
  autoplay="{{autoplay}}" interval="{{interval}}" duration="{{duration}}">
  <block wx:for="{{imgUrls}}">
    <swiper-item>
      <image src="{{item}}" class="slide-image" width="355" height="150"/>
    swiper-item>
  block>
swiper>
<button bindtap="changeIndicatorDots"> indicator-dots button>
<button bindtap="changeAutoplay"> autoplay button>
<slider bindchange="intervalChange" show-value min="500" max="2000"/> interval
<slider bindchange="durationChange" show-value min="1000" max="10000"/> duration
Page({
  data: {
    imgUrls: [
      'http://img02.tooopen.com/images/20150928/tooopen_sy_143912755726.jpg',
      'http://img06.tooopen.com/images/20160818/tooopen_sy_175866434296.jpg',
      'http://img06.tooopen.com/images/20160818/tooopen_sy_175833047715.jpg'
    ],
    indicatorDots: false,
    autoplay: false,
    interval: 5000,
    duration: 1000
  },
  changeIndicatorDots: function(e) {
    this.setData({
      indicatorDots: !this.data.indicatorDots
    })
  },
  changeAutoplay: function(e) {
    this.setData({
      autoplay: !this.data.autoplay
    })
  },
  intervalChange: function(e) {
    this.setData({
      interval: e.detail.value
    })
  },
  durationChange: function(e) {
    this.setData({
      duration: e.detail.value
    })
  }
})

效果如下图所示:

 

3、豆瓣API

在浏览器中输入豆瓣电影接口地址

http://api.douban.com/v2/movie/in_theaters

然后F12,打开调试窗口,选择Console,输入var a=接口返回的json串,如下图所示:

 

然后回车,再输入a,再回车,即可看到已经格式化的JSON对象,如下图所示:

4、从接口获取数据进行绑定

<block wx:for="{{movies}}">
    <view class="movie">
      <view class="pic">
        <image mode="aspectFit" src="{{item.images.medium}}">image>
      view>
      <view class="movie-info">
        <view class="base-info">
          <text>{{item.text}}text>
        view>
      view>
    view>
    <view class="hr">view>
  block>
// pages/movie/movie.js
Page({

  /**
   * 页面的初始数据
   */
  data: {
    imgUrls: [
      '../../assets/img/001.jpg',
      '../../assets/img/002.jpg',
      '../../assets/img/003.jpg'
    ],
    indicatorDots: true,
    autoplay: true,
    interval: 3000,
    duration: 1000,
    movies:[],
    hidden:false
  },

  /**
   * 生命周期函数--监听页面加载
   */
  onLoad: function (options) {
      this.loadMovie();
  },

  /**
   * 生命周期函数--监听页面初次渲染完成
   */
  onReady: function () {

  },

  /**
   * 生命周期函数--监听页面显示
   */
  onShow: function () {

  },

  /**
   * 生命周期函数--监听页面隐藏
   */
  onHide: function () {

  },

  /**
   * 生命周期函数--监听页面卸载
   */
  onUnload: function () {

  },

  /**
   * 页面相关事件处理函数--监听用户下拉动作
   */
  onPullDownRefresh: function () {

  },

  /**
   * 页面上拉触底事件的处理函数
   */
  onReachBottom: function () {

  },

  /**
   * 用户点击右上角分享
   */
  onShareAppMessage: function () {

  },
  /**
   * 加载电影
   */
  loadMovie:function(){
    var page = this;
    wx.request({
      url: 'http://api.douban.com/v2/movie/in_theaters',
      header:{
        'Content-Type':"application/json"
      },
      success:function(res){
      var subjects = res.data.subjects;
      processSubjects(subjects);
      page.setData({ movies: subjects, hidden:true});
      }
    })
  },
  /**
   * 
   */
  processSubjects: function (subjects) {
      //循环
    for (var i = 0; i < subjects.length;i++){
      var subject = subjects[i];
      this.processSubject(subject);
      }
  },
  /**
   * 
   */
  processSubject:function(subject){
      //名称
      var title = subject.title;
      //导演
      var directors  = subject.directors;
      var directorStr = "";
      for (var index in directors){
        directorStr= directorStr+directors[index].name+" / ";
      }
      if(directorStr!=""){
        directorStr = directorStr.substring(0,directorStr.length-2);
      }
      //主演
      var casts = subject.casts;
      var castStr = "";
      for(var index in casts){
        castStr= castStr+casts[index].name+" / ";
      }
      if(castStr!=""){
        castStr= castStr.substring(0,castStr.length-2);
      }
      //类型
      var genres = subject.genres;
      var genresStr = "";
      for(var index in genres){
        genresStr = genresStr+genres[index]+" / ";
      }
      if(genresStr!=""){
        genresStr= genresStr.substring(0,genresStr.length-2);
      }
      //年份
      var year = subject.year;
      //拼接字符串
      var text = "名称:"+title+"\n导演:"+directorStr+"\n主演:"+castStr+"\n类型:"+genresStr+"\n上映年份:"+year;
      subject.text = text;
  }

})

5、加载进度条

<view class="body-view">
  <loading hidden="{{hidden}}" bindchange="loadingChange">
    加载中...
  loading>
view>
data: {
    imgUrls: [
      '../../assets/img/001.jpg',
      '../../assets/img/002.jpg',
      '../../assets/img/003.jpg'
    ],
    indicatorDots: true,
    autoplay: true,
    interval: 3000,
    duration: 1000,
    movies:[],
    hidden:false
  },
/**
   * 加载电影
   */
  loadMovie:function(){
    var page = this;
    wx.request({
      url: 'https://api.douban.com/v2/movie/in_theaters',
      header:{
        'Content-Type':"application/json"
      },
      success:function(res){
      var subjects = res.data.subjects;
      processSubjects(subjects);
      page.setData({ movies: subjects, hidden:true});
      }
    })
  },
