小程序開發文檔針對底部導航，滑塊視圖實現，以及調用豆瓣電影api等做個一個整理文檔，供大家參考。
1、底部的tabBar

可設置的屬性有color、selectedColor、borderStyle、backgroundColor、list至少2個，最多5個（其屬性有pagePath、text、iconPath、selectedIconPath等）

"tabBar": {
    "color":"#dddddd",
    "selectedColor":"#3cc51f",
    "borderStyle":"black",
    "backgroundColor":"#2B2B2B",
    "list": [
      {
        "pagePath": "pages/movie/movie",
        "text": "影院熱映",
        "iconPath": "assets/img/dy-1.png",
        "selectedIconPath": "assets/img/dy.png"
      },
      {
        "pagePath": "pages/recommend/recommend",
        "text": "電影推薦",
        "iconPath": "assets/img/tj-1.png",
        "selectedIconPath": "assets/img/tj.png"
      },
      {
        "pagePath": "pages/search/search",
        "text": "查詢電影",
        "iconPath": "assets/img/search-1.png",
        "selectedIconPath": "assets/img/search.png"
      }
    ]
  },

2、 滑塊視圖容器 swiper

swiper

滑塊視圖容器。

從公共庫v1.4.0開始， change 事件返回 detail 中包含一個 source 字段，表示導致變更的原因，可能值如下：

• autoplay  自動播放導致swiper變化；
• touch  用戶劃動引起swiper變化；
• 其他原因將用空字符串表示。

注意 ：其中只可放置  組件，否則會導致未定義的行為。

swiper-item

僅可放置在  組件中，寬高自動設置為100%。

示例代碼：

<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
    })
  }
})
