基于jeecgboot-vue3的Flowable流程仿钉钉流程设计器-支持VForm3表单的选择与支持

因为这个项目license问题无法开源，更多技术支持与服务请加入我的知识星球。

1、初始化的时候加载表单

/** 查询表单列表 */
const getFormList = () => {
  listForm().then(res => formOptions.value = res.result.records)
}

2、开始节点的修改，增加表单选择

<el-tab-pane label="表单选择" name="formSelect">
       <el-form size="small" label-width="90px" @submit.native.prevent>
         <el-form-item label="表单" prop="formKey">
           <el-select v-model="activeData.formKey" placeholder="请选择表单" @change="updateFormKey" clearable>
             <el-option v-for="item in formOptions" :key="item.id" :label="item.formName" :value="item.id" />
           </el-select>
         </el-form-item>
         <el-form-item prop="localScope">
           <span slot="label">
             <el-tooltip content="若为节点表单，则表单信息仅在此节点可用，默认为全局表单，表单信息在整个流程实例中可用" placement="top-start">
               <i class="header-icon el-icon-info"></i>
             </el-tooltip>
             <span>节点表单</span>
           </span>
           <el-switch disabled  v-model="activeData.localScope" active-text="是" inactive-text="否" @change="updateFormScope()" />
         </el-form-item>
       </el-form>
    </el-tab-pane>

3、选择表单的更新，后续还要传递到父组件，以便其它组件使用这些字段

const updateFormKey = (formKey) => {
  console.log("updateFormKey formKey",formKey)
  props.activeData.formKey = formKey
  const formItem  = formOptions.value?.find((f) => f.id === formKey)
  const formContent = JSON.parse(formItem.formContent)
  props.activeData.formProperties = formContent.widgetList
  console.log("updateFormKey formProperties",props.activeData.formProperties)
}

4、相应watchEffect修改如下：

watchEffect(() => {
  const formProperties = props.activeData.formProperties
  props.activeData.formProperties = formProperties?.map((field) => ({
    id: field.id,
    name: field.options.label,
    readonly: field.options.readonly,
    hidden: field.options.hidden,
    required: field.options.required
  }))
  props.activeData.formProperties?.forEach((item) => {
    const properties = formProperties.find((f) => f.id === item.id)
    if (properties) {
      item.readonly = properties.options.readonly
      item.hidden = properties.options.hidden
      item.required = properties.options.required
    }
  })
})

5、效果图如下：
