Bpmn-js 属性控制

news2024/11/25 3:47:06

我们可以通过bpmn-js来访问对应的BPMN图例的属性信息。对应的流程图中的每个图例元素（如开始、结束、中间/边界事件等都通过businessObject属性存储对基础BPMN元素的引用。业务对象是从BPMN 2.0 XML导入并在导出过程中序列化的实际元素。使用业务对象来读取和写入BPMN特定的属性。

属性读取

我们需要通过关系图的图例的引用来获取对应的属性值：

var elementRegistry = bpmnJS.get('elementRegistry');

var sequenceFlowElement = elementRegistry.get('SequenceFlow_1'),
    sequenceFlow = sequenceFlowElement.businessObject;

sequenceFlow.name; // 'YES'
sequenceFlow.conditionExpression; // ModdleElement { $type: 'bpmn:FormalExpression', ... }

属性设置

在进行属性设置之前，需要了解bpmn-js内置支持哪些元素，哪些属性，具体的元素和属性可参考：bpmn.json文件，其详细内容如下：

当无需撤回操作支持的时候，可以使用如下方式写入属性：

var moddle = bpmnJS.get('moddle');


var newCondition = moddle.create('bpmn:FormalExpression', {
  body: '${ value > 100 }'
});

// write property, no undo support
sequenceFlow.conditionExpression = newCondition;

为了获得undo/redo支持，我们需要通过modeling来获取更新属性：

var modeling = bpmnJS.get('modeling');

modeling.updateProperties(sequenceFlowElement, {
  conditionExpression: newCondition
});

无论通过如上哪种方式更新，其最终都会将其生成xml文件进行保存。

测试示例

如下为截取官网的一个测试设置的Demo示例供参考，示例代码如下：

import {
  bootstrapModeler,
  inject
} from '../TestHelper';

import coreModule from 'bpmn-js/lib/core';
import modelingModule from 'bpmn-js/lib/features/modeling';


describe('bpmn properties', function() {

  var testModules = [
    coreModule,
    modelingModule
  ];


  var diagramXML = require('./diagram.bpmn');

  beforeEach(bootstrapModeler(diagramXML, {
    modules: testModules
  }));


  describe('read properties', function() {

    it('should read name', inject(function(elementRegistry) {

      // given
      var sequenceFlowElement = elementRegistry.get('SequenceFlow_1'),
          sequenceFlow = sequenceFlowElement.businessObject;

      // when
      var name = sequenceFlow.name;

      // then
      expect(name).to.eql('FOO > BAR?');
    }));


    it('should read conditionExpression', inject(function(elementRegistry) {

      // given
      var sequenceFlowElement = elementRegistry.get('SequenceFlow_1'),
          sequenceFlow = sequenceFlowElement.businessObject;

      // when
      var condition = sequenceFlow.conditionExpression;

      // then
      expect(condition.body).to.eql('${foo > bar}');
    }));

  });


  describe('write properties', function() {

    it('should write conditionExpression', inject(
      function(elementRegistry, moddle, modeling) {

        // given
        var sequenceFlowElement = elementRegistry.get('SequenceFlow_2'),
            sequenceFlow = sequenceFlowElement.businessObject;

        var newCondition = moddle.create('bpmn:FormalExpression', {
          body: '${ value > 100 }'
        });

        // assume
        expect(sequenceFlow.conditionExpression).not.to.exist;

        // when
        modeling.updateProperties(sequenceFlowElement, {
          conditionExpression: newCondition
        });

        // then
        expect(sequenceFlow.conditionExpression).to.equal(newCondition);
      }
    ));


    it('should undo write conditionExpression', inject(
      function(elementRegistry, moddle, modeling, commandStack) {

        // given
        var sequenceFlowElement = elementRegistry.get('SequenceFlow_2'),
            sequenceFlow = sequenceFlowElement.businessObject;

        var newCondition = moddle.create('bpmn:FormalExpression', {
          body: '${ value > 100 }'
        });

        modeling.updateProperties(sequenceFlowElement, {
          conditionExpression: newCondition
        });


        // when
        commandStack.undo();

        // then
        expect(sequenceFlow.conditionExpression).not.to.exist;
      }
    ));

  });

});
