Vue 甘特图 gantt 安装使用

(gantt-elastic)参考文章@shenjuncaci
(dhtmlx)参考文章@秃头的铲屎官
 dhtmlx@官方文档

安装

复制代码

npm i dhtmlx-gantt

使用

创建一个容器

复制代码

  <div ref="gantt" class="gantt-container"></div>

引入依赖

复制代码

import { gantt } from "dhtmlx-gantt";
import "dhtmlx-gantt/codebase/dhtmlxgantt.css";

初始化及数据解析

复制代码

        //  初始化
          gantt.init(this.$refs.gantt)
          //  数据解析
          gantt.parse(this.tasks)

其他配置可根据自己需求参考官网添加。

踩坑记录

样式不生效问题

再给 style 标签添加了 scoped 属性后 可能会出现样式不生效的问题

解决办法

scss 环境使用 ::v-deep进行样式穿透

less 环境使用 /deep/ 进行样式穿透

删掉 scoped 属性。

甘特图数据未渲染

再调用接口的数据赋值后，甘特图的数据为渲染。

可能原因：

gant 在实例的时候还没有获取到 data 数据

解决办法：

使用 async await 在获取的数据之后，再让 gant 进行实例

使用 this.$nextTick(()=>{}) 再拿到最新的数据后进行更新。

javascript 复制代码

//  数据初始化处理的方法
   initData: function () {
      this.tasks.data = this.jsondata.map((item) => {
        return {
          id: item.id,
          text: item.workItem,
          start_date: transitionYmdTime(item.planStartDate),
          end_date: transitionYmdTime(item.planCompletedDate),
          open: true, // 默认打开，
          toolTipsTxt: item.workItem
        }
      })
    },
//  甘特图数据接口
 gantDataSearch() {
      let bodyData = { apqpKey: this.apqpKey }
      API.apqpPowerMeeting(bodyData).then((res) => {
        this.jsondata = res.workItems
        this.$nextTick(() => {
            // 获取到数据后 进行数据处理
          this.initData()
          // 使用gantt实例 进行 初始化
          gantt.init(this.$refs.gantt)
          // 使用gantt实例  数据解析
          gantt.parse(this.tasks)
        })
        console.log('gant数据', res)
      })
    }
