微信小程序之滑动日历展示

滑动日历效果

效果预览

实现要求：顶部固定悬浮的是获取未来一周的日期，分为上下两部分，上面部分显示星期，下面则显示具体日期。今天则显示今天，可点击头部具体日期，可向左向右滑动。

实现代码

顶部日历

页面部分的代码

       <view wx:for="{{dayList}}" wx:for-index="index" class="tab-item {{currentSwiper==index ?'active':'noactive'}}" wx:key="index" bindtap='changeTab' data-current="{{index}}">
          <view class="TimeOrderBox scroll-view-item bc_red {{id == index ? 'coloBack':''}}" id="{{index}}" data-selectTime="{{item.month}}/{{item.day}}" data-week="{{item.week}}">
            <view class="TimesWD">
              <text class="TimeOrderText" wx:if="{{NowDay==item.day}}">今天</text>
              <text class="TimeOrderText" wx:else>周{{item.week}}</text>
              <view class="TimeOrderDay">
                <text class="TimeOrderTextDay">{{item.day}}</text>
              </view>
            </view>
          </view>
        </view>
      </view>

这里我们用View标签包裹起来，然后剩下的就是我们组装日期数据。我们来看js部分

 weekDate: function () {
    //获取周数据
    var myDate = new Date();// hehe
    myDate.toLocaleDateString();
    var month = myDate.getMonth() + 1;
    var time = myDate.getFullYear() + '年' + month + '月' + myDate.getDate() + '日';

    var total = 1;// 个数
    var dayList = [];
    dayList.push({
      'day': myDate.getDate(),
      'month': myDate.getMonth() + total,
      'week': toWeekDay(myDate.getDay()),
      'year': myDate.getFullYear()
    });
    for (var i = 0; i < 6; i++) {
      myDate.setDate(myDate.getDate() + total); // number 是最近几天  则会自动计算
      // 需求  月份-日   星期几
      dayList.push({
        'day': myDate.getDate(),
        'month': myDate.getMonth() + total,
        'week': toWeekDay(myDate.getDay()),
        'year': myDate.getFullYear()
      });
    }
    return dayList;
  }

function toWeekDay(weekDay) {// 传入数据  讲一周的某一天返回成中文状态下的字符
    switch (weekDay) {
        case 1: return '一'; break;
        case 2: return '二'; break;
        case 3: return '三'; break;
        case 4: return '四'; break;
        case 5: return '五'; break;
        case 6: return '六'; break;
        case 0: return '日'; break;
        default: break;
    }
    return '传入未知参数';
}

我们将一周的数据都封装进dayList中，然后返回。我们看下dayList返回了什么？

我们可以看到，通过上面js方法，我们得到了7条数据，分别有年、月、日以及星期几的数据。接下来我们看看css如何布局：

我们需要实现滑动效果，可以使用swiper组件。关于swiper的参数和用法，感兴趣的可以查下，我们快速讲下实现。

因为我们需要一些滑动展示不同的数据，这里我们mock一些 json数据仿照通过api返回过来的数据来解析：

{
  "isSuccess": true,
    "errorCode": 0,
      "errorMsg": null,
        "result": {
    "courseSeries": [
      {
        "date": "2018-12-24T00:00:00",
        "trainings": [
          {
            "id": 0,
            "duration": 90,
          
          },
          {
            "id": 0,
            "startTime": "2018-12-24T15:00:00",
            "duration": 60,
            "total": 0,
            "bookedNumber": 0
          },
          {
            "id": 0,
            "startTime": "2018-12-24T16:00:00",
            "duration": 60,
            "total": 0,
            "bookedNumber": 0
          }
        ]
      },
      {
        "date": "2018-12-25T00:00:00",
        "trainings": [
          {
            "id": 0,
            "startTime": "2018-12-25T08:00:00",
            "duration": 120,
            "total": 0,
            "bookedNumber": 0
          },
          {

            "duration": 90,
            "total": 0,
            "bookedNumber": 0
          },
          {
            "id": 0,
            "startTime": "2018-12-25T10:00:00",
            "duration": 90,
            "total": 0,
            "bookedNumber": 0
          },
          {
            "id": 0,
            "startTime": "2018-12-25T12:00:00",
            "duration": 120,
            "total": 0,
            "bookedNumber": 0
          },
          {
            "id": 0,
            "startTime": "2018-12-25T16:00:00",
            "duration": 120,
            "total": 0,
            "bookedNumber": 0
          }
        ]
      },
      {
        "date": "2018-12-26T00:00:00",
        "trainings": [
          {
            "id": 0,
            "startTime": "2018-12-26T08:00:00",
            "duration": 120,
            "total": 0,
            "bookedNumber": 0
          },
          {
            "id": 0,
            "startTime": "2018-12-26T10:00:00",
            "duration": 120,
            "total": 0,
            "bookedNumber": 0
          },
          {
            "id": 0,
            "startTime": "2018-12-26T14:00:00",
            "duration": 120,
            "total": 0,
            "bookedNumber": 0
          },
          {
            "id": 0,
            "startTime": "2018-12-26T16:00:00",
            "duration": 120,
            "total": 0,
            "bookedNumber": 0
          }
        ]
      },
      {
        "date": "2018-12-27T00:00:00",
        "trainings": []
       
      },
      {
        "date": "2018-12-28T00:00:00",
        "trainings": []
       
      },
      {
        "date": "2018-12-29T00:00:00",
        "trainings": []
       
      },
      {
        "date": "2018-12-30T00:00:00",
        "trainings": []
      }
    ]
  }

View Code

然后我们js中直接获取该Json数据。并解析成七条数据，因为我们显示的是一周数据

  onLoad: function () {
    let that=this;
    allList = [];
    that.filterday(mock.listData()["result"]["courseSeries"], that);
  },

 filterday: (res, options) => {
    let that = options;
    _.forEach(res, function (value) {
      that.coursesData(value, options);
    });
  },

  coursesData: (options, pargam) => {
    let that = pargam;
    if (options.trainings.length > 0) {
      let list = [];
      _.forEach(options.trainings, function (item, key) {
        list.push(item);
      });
      allList.push(list);
    } else {
      var objectData = {};
      allList = _.concat(allList, objectData);
    }
    let NowDay = new Date();
    console.log(that.weekDate());
    that.setData({
      dayList: that.weekDate(),
      dataShow: allList,
      NowDay: NowDay.getDate(),
    });
  },

其他需要注意的是滑动的时候有个滑动事件：switchSwiper，需要实现

 switchSwiper: function (e) {
    this.setData({
      currentSwiper: e.detail.current
    });
  },

另外，我们需要点击，所以此处也有点击周数据的时候点击事件：

changeTab: function (e) {
    console.log(e);
    this.setData({
      currentTab: e.currentTarget.dataset.current
    });
  },

最后我们的页面部分代码是：

  <swiper circular="circular"  bindchange="switchSwiper" current="{{currentTab}}" indicator-dots="{{indicatorDots}}" autoplay="{{autoplay}}" interval="{{interval}}" duration="{{duration}}">
    <block wx:for="{{dataShow}}" wx:key="index">
      <swiper-item>
       <view wx:if="{{dataShow[index].length>0}}">
         <view wx:for="{{dataShow[index]}}" wx:for-item="key" wx:key="index">
           <scroll-view scroll-y="{{true}}">
            <view class="contentBody">
               <text>
                {{key.duration}} -我是第{{index}}条数据
               </text>
             </view>
            <view class='heightView'></view>
           </scroll-view>
          </view>
        </view>
       <view wx:else><view class="contentBody"><text>暂无数据</text></view></view>
     </swiper-item>
   </block>
 </swiper>

这样的话，我们就可以展现出我们mock的一些数据

需要注意的是，上面当我们滑动的时候，我们是需要凸显当前所在的日期。

所以，在顶部周数据的时候，需要稍微做下处理。

 <view class="TimeOrderBox scroll-view-item bc_red {{id == index ? 'coloBack':''}}" id="{{index}}" data-selectTime="{{item.month}}/{{item.day}}" data-week="{{item.week}}">

这样基本上就已经实现了整体代码，
