利用绝对定位实现日程渲染

效果：

1、数据结构：Calendar/data.js

export const data = [
  { id: 0, hour: '00:00' },
  { id: 1, hour: '01:00' },
  { id: 2, hour: '02:00' },
  { id: 3, hour: '03:00' },
  { id: 4, hour: '04:00' },
  { id: 5, hour: '05:00' },
  {
    id: 6,
    hour: '06:00',
    task: [
      { id: 1, title: '周计划', hour: '06:00', type: 1 },
      { id: 2, title: '周计划1', hour: '06:30', type: 1 },
      { title: '自建任务', hour: '06:45', type: 2 },
      { title: '自建任务', hour: '06:13', type: 2 },
      { title: '自建任务', hour: '06:00', type: 2 },
      { title: '自建任务', hour: '06:00', type: 2 },
      { title: '自建任务', hour: '06:00', type: 2 },
      { title: '自建任务', hour: '06:00', type: 2 },
      { title: '自建任务', hour: '06:00', type: 2 },
      { title: '自建任务', hour: '06:00', type: 2 },
      { title: '自建任务', hour: '06:00', type: 2 },
      { title: '自建任务', hour: '06:00', type: 2 },
      { title: '自建任务', hour: '06:00', type: 2 },
      { title: '自建任务', hour: '06:00', type: 2 },
      { title: '自建任务', hour: '06:00', type: 2 }
    ]
  },
  { id: 7, hour: '07:00' },
  { id: 8, hour: '08:00', task: [{ title: '周计划', hour: '00:00', type: 1 }] },
  { id: 9, hour: '09:00' },
  { id: 10, hour: '10:00' },
  { id: 11, hour: '11:00' },
  { id: 12, hour: '12:00' },
  { id: 13, hour: '13:00' },
  { id: 14, hour: '14:00' },
  { id: 15, hour: '15:00' },
  { id: 16, hour: '16:00' },
  { id: 17, hour: '17:00' },
  { id: 18, hour: '18:00' },
  { id: 19, hour: '19:00' },
  { id: 20, hour: '20:00' },
  { id: 21, hour: '21:00' },
  { id: 22, hour: '22:00' },
  { id: 23, hour: '23:00' }
]

2、利用定位实现：Calendar/index.vue

<template>
  <div class="calendar">
    <ul ref="wrapperRef" class="timer-shaft">
      <li v-for="(item,index) of data" :key="index">
        <div class="hour"><span>{{item.hour}}span>div>
        <ul>
          <li :class="task.type===1?'self':''" v-for="(task,i) of item.task" :key="i" :style="{left:`${i*30}px`}" @click="handleDetail(task)">
            <p>{{task.hour}}p>
            <p>{{task.title}}p>
          li>
        ul>
      li>
    ul>
  div>
template>
<script>
import { data } from './data'
export default {
  data() {
    return { data }
  },
  methods: {
    handleDetail(item) {
      console.log(item)
    }
  },
  created() {
    this.$nextTick(() => {
      this.$refs.wrapperRef.scrollTop = 300
    })
  }
}
script>
<style lang="less" scoped>
.calendar {
  height: 100%;
  line-height: 1;
  background-color: #fff;
  display: flex;
  flex-direction: column;
  color: #4d5c82;
  > ul.timer-shaft {
    flex: 1;
    overflow-y: auto;
    -webkit-overflow-scrolling: touch;
    padding: 15px;
    box-sizing: border-box;
    > li {
      height: 50px;
      display: flex;
      > .hour {
        width: 40px;
        text-align: left;
        font-size: 12px;
        position: relative;
        > span {
          position: absolute;
          top: -6px;
        }
      }
      > ul {
        flex: 1;
        border-top: 1px solid #e0e5f5;
        overflow-x: auto;
        -webkit-overflow-scrolling: touch;
        position: relative;
        &::-webkit-scrollbar {
          display: none;
        }
        > li {
          width: 72px;
          background-color: #fff;
          box-shadow: 2px 2px 4px 0 rgba(57, 78, 145, 0.1);
          border-radius: 0 4px 4px 0;
          border-left: 4px solid #416eff;
          padding: 4px;
          box-sizing: border-box;
          position: absolute;
          top: 1px;
          z-index: 1;
          &.self {
            border-color: #62d78e;
          }
          > p {
            line-height: 20px;
            font-size: 12px;
          }
        }
      }
    }
  }
}
