8、同时可以进行流程的编辑

/** 编辑流程设计弹窗页面 */
  const handleLoadXml = (row) => {
    console.log("handleLoadXml row",row)
    designerData.title = "流程设计 - " + row.name;
    designerData.deploymentId = row.deploymentId;
    designerData.form = {
      processType: [],
      processName: row.name,
      processKey: row.key
    }
    if (row &&row.deploymentId) {
      const selectItem = categorys.value.find(item => item.id == row.category);
      modelForm.processType = selectItem; //以便编辑保存的时候获取到processType
      designerData.form.processType.push(selectItem);
      designerData.loading = true;
      console.log("designerData",designerData)
      handleReadImage(row.deploymentId);
      designerData.title = "编辑流程图";  
    }
    xmlFrame.width = '90%'
  }
  /** 流程图查看 */
  const handleReadImage = (deploymentId) => {
    designerData.open = true;
    xmlFrame.width = '70%';
    readXml(deploymentId).then(res => {
      if (res.success) {
        designerData.bpmnXml = res.result;
        designerData.loading = false;
        designerOpen.value = true;
      } else {
        createMessage.error("获取流程图失败！")
      }
    })
  }

9、同时ElementBaseInfo.vue文件修改如下

<template>
  <div class="panel-tab__content">
    <el-form size="small" label-width="90px" @submit.prevent>
      <el-form-item label="ID">
        <el-input
          v-model="elementBaseInfo.id"
          :disabled="idEditDisabled || elementBaseInfo.$type === 'bpmn:Process'"
          clearable
          @change="updateBaseInfo('id')"
        />
      </el-form-item>
      <el-form-item label="名称">
        <el-input v-model="elementBaseInfo.name" clearable @change="updateBaseInfo('name')" />
      </el-form-item>
      <!--流程的基础属性-->
      <template v-if="elementBaseInfo.$type === 'bpmn:Process'">
        <el-form-item label="流程分类">
          <el-input :disabled= "true" v-model="processType[0].name"/>
        </el-form-item>
        <el-form-item label="应用类型">
          <el-input :disabled= "true" v-model="processType[0].appType"/>
        </el-form-item>
        <el-form-item label="版本标签">
          <el-input v-model="elementBaseInfo.versionTag" clearable @change="updateBaseInfo('versionTag')" />
        </el-form-item>
        <el-form-item label="可执行">
          <el-switch v-model="elementBaseInfo.isExecutable" active-text="是" inactive-text="否" @change="updateBaseInfo('isExecutable')" />
        </el-form-item>
      </template>
      <el-form-item v-if="elementBaseInfo.$type === 'bpmn:SubProcess'" label="状态">
        <el-switch v-model="elementBaseInfo.isExpanded" active-text="展开" inactive-text="折叠" @change="updateBaseInfo('isExpanded')" />
      </el-form-item>
    </el-form>
  </div>
</template>
<script lang="ts" setup>
  import { ref, watch, onBeforeUnmount, toRaw } from 'vue'; 
  defineOptions({ name: 'ElementBaseInfo' })
  const props = defineProps({
    businessObject: {
      type: Object,
      default: () => {}
    },
    processType: {
        type: Array,
        default: () => []
    },
    type: String,
    idEditDisabled: {
        type: Boolean,
        default: true
    }
  })

  const bpmnElement = ref()
  const elementBaseInfo = ref<any>({})
  const bpmnInstances = () => (window as any)?.bpmnInstances
  const appType = ref("")

  const resetBaseInfo = () => {
    bpmnElement.value = bpmnInstances()?.bpmnElement || {}
    elementBaseInfo.value = bpmnElement.value.businessObject
    if (elementBaseInfo.value && elementBaseInfo.value.$type === "bpmn:SubProcess") {
      elementBaseInfo.value["isExpanded"] = elementBaseInfo.value.di?.isExpanded
    }
  }

  const updateBaseInfo = (key: string) => {
    if (key === "id") {
      bpmnInstances().modeling.updateProperties(toRaw(bpmnElement.value), {
          id: elementBaseInfo.value[key],
          di: { id: `${elementBaseInfo.value[key]}_di` }
        });
        return;
      }
    if (key === "isExpanded") {
        bpmnInstances().modeling.toggleCollapse(toRaw(bpmnElement.value));
        return;
    }

    const attrObj = Object.create(null);
    attrObj[key] = elementBaseInfo.value[key]
    bpmnInstances().modeling.updateProperties(toRaw(bpmnElement.value), attrObj);
  }

  watch(
    () => props.businessObject,
    (val) => {
      if (val) {
        resetBaseInfo()
      }
    }
  )
   
  onBeforeUnmount(() => {
    bpmnElement.value = null
  })

</script>
