gantt安装与使用

vue版---部分功能收费

1. 安装gantt  或  引入文件

   npm install dhtmlx-gantt -save或import gantt from "/public/static/dhtmlxgantt/dhtmlxgantt.js";
   import "/public/static/dhtmlxgantt/locale/locale_cn.js";

2. 引入---组件

<template>
#节点高度要给，gantt不根据内容撑开<div ref="gantt" class="gantt-container" style="min-height: calc(85vh - 100px); width: 100%; overflow: hidden"></div>
</template>
<script>import gantt from "/public/static/dhtmlxgantt/dhtmlxgantt";import "/public/static/dhtmlxgantt/locale/locale_cn.js";
</script>

定义渲染数据 

let tasks = ref({data: [{id: 1,text: "计划#1",start_date: "2023-09-28",end_date: "2023-10-28",sj_start_date: "2023-09-29",sj_end_date: "2023-10-25",open: true,},{id: 2,text: "已完成",start_date: "2023-09-28",end_date: "2023-10-28",sj_start_date: "2023-09-29",sj_end_date: "2023-10-25",parent: 1,},{id: 3,text: "计划#2",start_date: "2023-03-10",end_date: "2023-5-20",sj_start_date: "2023-03-10",sj_end_date: "2023-5-18",open: true,},{id: 4,text: "已完成",start_date: "2023-03-10",end_date: "2023-5-20",sj_start_date: "2023-03-10",sj_end_date: "2023-5-18",parent: 3,},],
});
