star fork


A process designer that depends on bpmn.js , Vue 2.x and ElementUI.

一个基于 bpmn.jsVue 2.xElementUI 开发的流程设计器。

You can view and edit BPMN 2.0 diagrams in the browser.

您可以使用它在浏览器上查看和编辑符合 BPMN 2.0 规范的流程文件。

For on line demo, please visit MiyueFE Blog

码云同步镜像请访问 Gitee/MiyueSC Process Designer

针对之前的版本存在的问题,第二版采用了在 window 对象下添加新的命名空间来保存对应的实例对象。

原因是因为 通过 Props 传参会被 vue 进行响应式处理,会更改原对象的原型链指向。

3.1 MyProcessDesigner

3.1.1 Attributes

Attribute Description Type Accepted Values Default
value/v-model 初始化流程对应的 xml 字符串 String - -
translations 翻译文件 Object - zh.js
additionalModel 自定义的附加模块 Object[] / Object - -
moddleExtension 自定义的扩展模块 Object - -
onlyCustomizeAddi 仅使用开发时的自定义附加模块 Boolean - false
onlyCustomizeModdle 仅使用开发时的自定义扩展模块 Boolean - false
prefix 流程引擎对应扩展属性前缀 String camunda, activiti, flowable camunda
events 需要使用的事件列表,可用事件见 Bpmn.js 中文文档 Array - [element.click]
headerButtonSize 头部按钮组的大小 String "default", "medium", "small", "mini" small

3.1.2 Events

Event Name Description Callback Parameters
init-finished 流程实例等初始化完成之后 modeler
change 流程发生可监听的改变时 ( EventBus.on("commandStack.changed")) XMLString
destroy 组件准备销毁时,此时流程实例已经销毁 modeler
BpmnEvents Like element.click, will replace . to - (ex: "element.click" => "element-click" ). If you want to use an event, you must add the event name to the "events" parameter
传入参数 events 对应的事件发生时触发,会将 events 数组内部的事件名称中的 . 替换成 - 来适配 vue 的自定义监听事件。比如 "element.click" 会变成 element-click
element, InternalEventInstance
