vue3使用vis绘制甘特图制作timeline可拖动时间轴及时间轴中文化(推荐)

前言:参考文档文章

vis官方配置文档:文档地址
参考使用文章:文章地址

一、实现效果:

在这里插入图片描述

二、安装插件及依赖:

cnpm install -S vis-linetime
cnpm install -S vis-data
cnpm install -S moment

三、封装组件:

下端时间轴单独封装成组件

在这里插入图片描述

在这里插入图片描述

1.html部分:

<template>
  <div class="visGantt" ref="visGanttDom"></div>
</template>

2.引入依赖:

import { DataSet } from 'vis-data/peer'
import { dateFormat } from '@/util' //封装的时间格式化函数,如下所示
import { Timeline } from 'vis-timeline/peer'
import 'vis-timeline/styles/vis-timeline-graph2d.css'
const moment = require('moment')

时间格式化函数:

export function dateFormat(date, fmt) { //date是日期,fmt是格式
    let o = {
        'M+': date.getMonth() + 1, // 月份
        'd+': date.getDate(), // 日
        'H+': date.getHours(), // 小时
        'h+': date.getHours(), // 小时
        'm+': date.getMinutes(), // 分
        's+': date.getSeconds(), // 秒
        'q+': Math.floor((date.getMonth() + 3) / 3), // 季度
        S: date.getMilliseconds() // 毫秒
    }
    if (/(y+)/.test(fmt)) {
        fmt = fmt.replace(RegExp.$1, (date.getFullYear() + '').substr(4 - RegExp.$1.length))
    }
    for (var k in o) {
        if (new RegExp('(' + k + ')').test(fmt)) {
            fmt = fmt.replace(RegExp.$1, (RegExp.$1.length === 1) ? (o[k]) : (('00' + o[k]).substr(('' + o[k]).length)))
        }
    }
    return fmt
}

3.父组件传入数据:

let props = defineProps({
  ganntData: { // 初始传入数据
    type: Object,
    default: () => {}
  },
  ganntHistoryData: { // 全部的历史数据,为了实现撤销上一步
    type: Object,
    default: () => {}
  }
})

4.js部分全部配置

配置项参考官方文档,仅注释解释个别方法。

<script setup>
import { ref, defineProps, watch, nextTick, defineEmits } from 'vue'
import { DataSet } from 'vis-data/peer'
import { dateFormat } from '@/util'

        checkTimeConflict()
      })
    }

        value: trackTimeWindowIndex + 1,
        className: `visGantt-item${trackTimeWindowIndex % 10}`
      })
      // 项目时间数组
      trackTimeWindow.timeWindows.forEach((timeWindow, timeWindowIndex) => {
        timeWindows.push({
          start: new Date(timeWindow.startTime),
          startTime: timeWindow.startTime,

      return Math.round(date / day) * day
    },
    // 移动时返回函数
    onMove: function(item, callback) {
      // 深拷贝一下,不能直接修改父组件数据
      historyDataArray.value = JSON.parse(JSON.stringify(props.ganntHistoryData))
      let historyData = []
      // props.ganntHistoryData是全部的历史数据,historyData 是取上一步的数据
      historyData = JSON.parse(JSON.stringify(props.ganntHistoryData[props.ganntHistoryData.length - 1]))
      // 更改一下格式
      historyData[0].trackTimeWindows.forEach((eachItem)=>{
        if (eachItem.deviceId === item.deviceId) {
          if (!item.start || !item.end) {
            return
          }
          eachItem.timeWindows[0].startTime = item.start
          eachItem.timeWindows[0].stopTime = item.end
        }

      let tooltipDom = document.getElementsByClassName('vis-tooltip')
      tooltipDom[0].style.visibility = 'hidden'
      callback(item)
    }
  }
  timeline.value = new Timeline(container)
  timeline.value.redraw()
  timeline.value.setOptions(options)
  timeline.value.setGroups(groups)
  timeline.value.setItems(items)
  timeline.value.on('select', onSelect)
}
</script>

四、父组件调用

1.引入子组件

<div v-loading="loading"> // loading是为了有个加载效果,为了美观
	<time-line 
	:ganntData="ganntData"  // 原始数据
	v-model:ganntHistoryData="ganntHistoryData"  // 历史数据
	@selectItem="timelineSelected" //选择事件
	>
	</time-line>
</div>
import TimeLine from '@/components/modules/planControl/TimeLine'

2.初始数据

let props = defineProps({
 // 因为这个父组件是通过点击进来的,所以有传入的数据,也可以直接赋值ganntData 数据,可以省略watch里面的转格式
  conflictList: {
    type: Array,
    default: null
  }
})
const ganntData = reactive([
  {
    name: 'confilct',
    trackTimeWindows: [
    ]
  }
])

const ganntHistoryData = ref([])

// 传入数据变化时为ganntData和ganntHistoryData赋值。
watch(
  () => props.conflictList, (newValue) => {
    ganntData[0].trackTimeWindows.length = 0
    newValue.forEach(element => {
      ganntData[0].trackTimeWindows.push({
        deviceId: element.content,
        timeWindows: [
          {
            startTime: element.startTime,
            stopTime: element.stopTime
          }
        ]
      })
    })
    // 记录操作历史
    ganntHistoryData.value.length = 0
    ganntHistoryData.value.push(ganntData)
  },
  {
    deep: true,
    immediate: true
  }
)

原数据(省略部分未使用参数):

[
    {
        "id": 1,
        "content": "xxxxxxxxxxxxxx计划1",
        "time": "2023.08~10",
        "startTime": "2023-08-09",
        "stopTime": "2023-10-20"
    },
    {
        "id": 2,
        "content": "xxxxxxxxxxxxxx计划2",
        "time": "2023.09~11",
        "startTime": "2023-09-09",
        "stopTime": "2023-11-1"
    },
    {
        "id": 3,
        "content": "xxxxxxxxxxxxxx计划3",
        "time": "2023.08~10",
        "startTime": "2023-08-20",
        "stopTime": "2023-10-1"
    }
]

3.父组件按钮及事件

仅展示原始图撤销事件。

    <div>
      <div>
        <el-button @click="reset()">原始图</el-button>
        <el-button @click="preNode()">撤销</el-button>
        <el-button>一键调整</el-button>
      </div>
      <div>
        <el-button>取消</el-button>
        <el-button>保存并退出</el-button>
      </div>
    </div>

回归原始图事件:
大致思路:先把ganntData清空,将拿到的props.conflictList里的数据赋值给ganntData,再把ganntData的数据push进ganntHistoryData中

 // showResetTip 是显示一个“已回到初始状态”的提示框,可以自己封装或者使用组件,此处不展示
const showResetTip = ref(false)
const loading = ref(false)
const reset = () => {
  // loading是加载效果
  loading.value = true
  ganntData[0].trackTimeWindows.length = 0
  props.conflictList.forEach(element => {
    ganntData[0].trackTimeWindows.push({
      deviceId: element.content,
      timeWindows: [
        {
          startTime: element.startTime,
          stopTime: element.stopTime
        }
      ]
    })
  })
  showResetTip.value = true
  ganntHistoryData.value.splice(0)
  ganntHistoryData.value.push(ganntData)
  setTimeout(() => {
    showResetTip.value = false
    loading.value = false
  }, 1000)
}

撤销事件:
大致思路:拿到子组件返回的ganntHistoryData历史数据数组,删掉最后一组数据后:
如果历史数据数组的长度<= 1,代表再撤销就回到原始状态了,那就直接调用reset()回到原始图;
否则,将ganntHistoryData删掉最后一组数据后的ganntHistoryDataClone最后一组值赋给ganntData,

const preNode = () => {
  // loading是加载效果
  loading.value = true
  let ganntHistoryDataClone = []
  ganntHistoryDataClone = JSON.parse(JSON.stringify(ganntHistoryData.value))
  ganntHistoryDataClone.splice(ganntHistoryDataClone.length - 1, 1)
  if (ganntHistoryDataClone.length <= 1) {
    reset()
  } else {
    ganntData[0] = ganntHistoryDataClone[ganntHistoryDataClone.length - 1][0]
    ganntHistoryData.value = JSON.parse(JSON.stringify(ganntHistoryDataClone))
  }
  setTimeout(() => {
    loading.value = false
  }, 1000)
}
