效果图

项目介绍

easy-flow 基于VUE+ElementUI+JsPlumb的流程设计器,通过 vuedraggable 插件来实现节点拖拽。

功能介绍

  • 支持拖拽添加节点
  • 点击线进行设置条件
  • 支持给定数据加载流程图
  • 支持画布拖拽
  • 支持连线样式、锚点、类型自定义覆盖
  • 支持力导图

更新日志

2020年11月12日

  • 新增力导图自适应布局,只需要提供节点、节点和节点之间的关系即可自动计算坐标(比没有坐标好些)

2020年8月6日

2019年08月23日

  • 修改IE 11.316版本下无法拖拽问题
  • 新增演示环境地址, 演示地址

2019年08月22日

  • 修改火狐浏览器下不能够拖拽问题

操作说明

  • 左侧菜单子节点可以拖拽,将其拖拽到右侧画板中松开鼠标即可添加一个节点
  • 节点分为3部分,左边为标识节点的图标,中间节点的描述,右变为节点的状态图标,鼠标从左变图标上可以拖拽出连线,可以连接其他节点,拖动左侧图标以外位置可以改变节点在页面的位置

如何集成

  • 下载源码

  • 在自己的vue工程中找到package.json,并引入如下依赖(不用额外引入jsplumb)

      "element-ui": "2.9.1",
      "lodash": "4.17.15",
      "vue": "^2.5.2",
      "vue-codemirror": "^4.0.6",
      "vuedraggable": "2.23.0"
  • 将easy-flow/src/components/ef 目录复制到自己工程的一个目录下(如/src/views)

  • 修改main.js,引入elementUI和easy-flow样式

    import ElementUI from 'element-ui'
    import 'element-ui/lib/theme-chalk/index.css'
    import '@/这个为复制后的目录,src就不要写了/ef/index.css'
    Vue.use(ElementUI, {size: 'small'})
