vue 甘特图 一行多条任务 可拖拽

1、安装 highcharts

npm install highcharts --save

2、页面引用

// 引入
import Highcharts from 'highcharts/highcharts-gantt.src.js'
// 引入拖拽
import factory from 'highcharts/modules/draggable-points.js'
factory(Highcharts)

3、封装组件

}
</script>

<style lang="less" scoped>
.BaseNewGantt {
  height: calc(100% - 70px);
  overflow: auto;
}
</style>

4、组件使用

<base-gantt
  ref="gantt"
  :ganttConfig="ganttConfig"
  @onDragStop="onDragStop"
  @onHandleSelect="onHandleSelect">
</base-gantt>

data中配置

   // 甘特图配置
    ganttConfig: {
      // 数据源
      data: [],
      // 左侧表格列配置
      tableConfig: [
        {
          title: '设备名称',
          labels: 'machineName',
        },
        {
          title: '设备编码',
          labels: 'machineNo',
        },
      ],
    },

事件

// 拖动停止
onDragStop(option) {},
// 甘特图选中
onHandleSelect(option) {
  this.selectGanttRowData = option
},
