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

npm i dhtmlx-gantt

使用

创建一个容器

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

引入依赖

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

初始化及数据解析

        //  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。

//  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.workItemsthis.$nextTick(() => {// 获取到数据后 进行数据处理this.initData()// 使用gantt实例 进行 初始化gantt.init(this.$refs.gantt)// 使用gantt实例  数据解析gantt.parse(this.tasks)})console.log('gant数据', res)})}
