vue使用 jsplumb 生成流程图

1、安装jsPlumb：

npm install jsplumb

2、在使用的 .vue 文件中引入

import { jsPlumb } from "jsplumb";

简单示例：

注意：注意看 id 为"item-3"和"item-9"那条数据的连线配置

其中有几个小图片，可以用自己的本地图片代替（图标大小的）

<template><div id="wrapper"><div class="line-wrap" v-if="flowChartData1.length == 2"><div :id="flowChartData1[1].id" class="state-item">{{ flowChartData1[1].lable }}</div></div><div class="line-wrap"><div v-for="(item, index) in flowChartData" :key="index" :id="item.id" :class="item.nodeName == 'start' || item.nodeName == 'end' || item.nodeName == 'summary' ?
