文章主要内容是关于如何在项目中引入依赖项以及编写组件代码的步骤和总结,作者分享了个人经验,旨在为读者提供参考,并鼓励大家支持脚本之家
vue实现甘特图
1、引入依赖
npm install dhtmlx-gantt@6.3.7
2、组件代码
<template>
<div class="app-container">
<div ref="gantt" class="left-container" />
</div>
</template><script>
import gantt from 'dhtmlx-gantt' // 引入模块
//import 'dhtmlx-gantt/codebase/dhtmlxgantt.css'
import 'dhtmlx-gantt/codebase/skins/dhtmlxgantt_terrace.css' //皮肤
import 'dhtmlx-gantt/codebase/locale/locale_cn' // 本地化
import 'dhtmlx-gantt/codebase/ext/dhtmlxgantt_tooltip.js' //任务条悬浮提示
export default {
name: 'Gantt',
data() {
return {
tasks: {

},
}
},
mounted() {
