上一节虽然显示正常了，但还是有点问题，就是不能正确地进行数据保存与更新

6、数据变化后的更新操作

因为原先的代码基于vue2，所以有些逻辑判断与更新还是需要重新写的，否则有问题

一个是逻辑判断修改成响应式变量的值获取type.value

另外就是更新的时候bpmnElement.value还是要转成toRaw

//时间事件定义类型修改
  const updateTime = (type,value) => {
    //获取节点的子节点 timerEventDefinition
    //console.log("updatetime type.value=",type.value)
    let timerEventDef = bpmnInstances().bpmnElement.businessObject.eventDefinitions[0]
    console.log("updatetime timerEventDef=",timerEventDef)
    const timeCycle = bpmnInstances().moddle.create("bpmn:FormalExpression", { body:value });
    const timeDate = bpmnInstances().moddle.create("bpmn:FormalExpression", { body:value });
    const timeDuration = bpmnInstances().moddle.create("bpmn:FormalExpression", { body:value });
    if (type.value == 'timeCycle') {
      bpmnInstances().modeling.updateModdleProperties(toRaw(bpmnElement.value),timerEventDef,{timeDate:null})
      bpmnInstances().modeling.updateModdleProperties(toRaw(bpmnElement.value),timerEventDef,{timeDuration:null})
      bpmnInstances().modeling.updateModdleProperties(toRaw(bpmnElement.value),timerEventDef,{timeCycle })
    }
    else if (type.value == 'timeDate') {
      console.log("updatetime timeDate")
      bpmnInstances().modeling.updateModdleProperties(toRaw(bpmnElement.value),timerEventDef,{timeCycle:null})
      bpmnInstances().modeling.updateModdleProperties(toRaw(bpmnElement.value),timerEventDef,{timeDuration:null})
      bpmnInstances().modeling.updateModdleProperties(toRaw(bpmnElement.value),timerEventDef,{ timeDate })
    }
    else if (type.value == 'timeDuration') {
      bpmnInstances().modeling.updateModdleProperties(toRaw(bpmnElement.value),timerEventDef,{timeDate:null})
      bpmnInstances().modeling.updateModdleProperties(toRaw(bpmnElement.value),timerEventDef,{timeCycle:null})
      bpmnInstances().modeling.updateModdleProperties(toRaw(bpmnElement.value),timerEventDef,{ timeDuration })
    }
  }

7、更新后的再次点击获取数据

这个部分主要是逻辑判断要更新一下，如下，原先的判断会有逻辑问题

const getElementLoop = (businessObject) => { //获取定时边界事件原有值
    console.log("getElementLoop businessObject=",businessObject)
    //console.log("bpmnInstances().bpmnElement.businessObject=",bpmnInstances().bpmnElement.businessObject);
    if(businessObject.eventDefinitions && businessObject.eventDefinitions.length>0){
      if(businessObject.eventDefinitions[0].$type == 'bpmn:TimerEventDefinition') {
        if(businessObject.eventDefinitions[0].timeDuration) {
          timeDefinitionType.value = "timeDuration"
          FormalExpression.value = businessObject.eventDefinitions[0].timeDuration.body
        }
        else if(businessObject.eventDefinitions[0].timeDate) {
          timeDefinitionType.value = "timeDate"
          FormalExpression.value = businessObject.eventDefinitions[0].timeDate.body
        }
        else if(businessObject.eventDefinitions[0].timeCycle) {
          timeDefinitionType.value = "timeCycle"
          FormalExpression.value = businessObject.eventDefinitions[0].timeCycle.body
        }
      }
    }
  }

8、通过上面修改好后，整个保存，再次显示都正常了

<template>
  <div class="panel-tab__content">
    <!--目前只处理定时边界事件 -->
    <el-form size="mini" label-width="90px" @submit.native.prevent >
      <el-form-item label="事件类型">
        <el-select v-model="timeDefinitionType" @change="changeTimerType"  v-if= "businessObject.eventDefinitions && businessObject.eventDefinitions[0].$type.indexOf('TimerEventDefinition') !== -1"  >
          <!--bpmn:TimerEventDefinition-->
          <el-option label="指定时间" value="timeDate" />
          <el-option label="持续时间" value="timeDuration" />
          <el-option label="周期执行" value="timeCycle" />
        </el-select>
      </el-form-item>
      <template v-if="timeDefinitionType != ''">
        <el-form-item label="时间设置" required>
            <el-tooltip>
              <el-input size="mini" type="string" v-model="FormalExpression" @change="updateTimeValue"></el-input>
              <template #content>
                事件类型配置说明<br>
                1.指定时间(timeDate):触发事件的时间,如:2022-12-16T11:12:16 <br>
                2.持续时间(timeDuration):指定时器之前需等待多长时间,使用ISO 8601规定的格式<br>
                 (由BPMN 2.0规定),如PT5M(等待5分钟),也支持表达式${duration},<br>
                 这样你就可以通过流程变量来影响定时器定义<br>
                3.周期执行(timeCycle):指定重复执行的间隔,可以用来定期启动流程实例,<br>
                或为超时时间发送多个提醒。timeCycle元素可以使用两种格式。<br>
                第一种是 ISO 8601 标准的格式。示例值(R3/PT5M)(重复3次,<br>
                每次间隔5分钟),或也可以用cron表达式指定timeCycle,如从整点开始,<br>
                每10分钟执行一次(0 0/10 * * * ?)<br>
              </template>
            </el-tooltip>
        </el-form-item>
      </template>
    </el-form>
  </div>
</template>
