实现周一到周日时间的多选(使用的是uniApp框架)

WXML:
<view class="form-item left-class" @click="hanleOpenWeek">
  <view class="label">周时间</view>
  <view class="mid-block">{{ info.weekTime | filterWeekTime }}</view>
  <uni-icons class="icon" type="arrowright" color="#999999" size="20" />
</view>


// 模态框modal

<uni-popup ref="weekModal" type="bottom">
  <view class="modal-content">
    <view class="modal-head">选择时间</view>
    <view class="modal-body">
      <block v-for="(item, index) in weekOptions" :key="item.id">
        <view class="text-block">
          <view class="title">
            <view class="label" :class="{ 'label-active': preCheckList.includes(item.id) }">{{ item.label }}</view>
          </view>
          <uni-icons
            class="icon"
            size="32"
            :type="preCheckList.includes(item.id) ? 'checkbox-filled' : 'circle'"
            :color="preCheckList.includes(item.id) ? '#3B79FF' : '#BFBFBF'"
            @click="handleWeekClick(item)"
          />
        </view>
      </block>
    </view>
    <view class="modal-foot">
      <button class="uni-default-button btn" @click.stop="handleWeekConfirm">确定</button>
    </view>
  </view>
</uni-popup>

JS:

  const weekOptions = [
    {
      id: '1',
      label: '周一'
    },
    {
      id: '2',
      label: '周二'
    },
    {
      id: '3',
      label: '周三'
    },
    {
      id: '4',
      label: '周四'
    },
    {
      id: '5',
      label: '周五'
    },
    {
      id: '6',
      label: '周六'
    },
    {
      id: '7',
      label: '周日'
    }
  ]

  data () {
    return {
      info: {
        weekOptions,
        preCheckList: [],
        weekTime: ['1', '2', '3', '4']
      }
    }
  },


  // 时间的过滤器---拿到的是['1','3','5','6']数组,需将其转化成中文显示
  filters: {
    filterWeekTime (arr) {
      let result = []
      weekOptions.forEach(item => {
        if (arr.includes(item.id)) {
          result.push(item.label)
        }
      })
      return result.join(',') || '选择周时间'
    }
  },


  methods: {
    // 打开modal
    hanleOpenWeek () {
      let { info } = this
      //打开的时候选中状态---此处必须为深拷贝
      this.preCheckList = _.cloneDeep(info.weekTime)
      this.$refs['weekModal'].open()
    },


    // modal的选中
    handleWeekClick (item) {
      let { preCheckList } = this
      // 选择中的时候如果有这个id,就删除这一条,木有就添加
      let idx = preCheckList.indexOf(item.id)
      if (idx > -1) {
        this.preCheckList.splice(idx, 1)
      } else {
        this.preCheckList.push(item.id)
      }
    },


    // modal的确认
    handleWeekConfirm () {
      // 确认的时候需要进行排序
      this.info.weekTime = this.preCheckList.sort()
      this.$refs['weekModal'].close()
    }
  }
