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

4、相应watchEffect修改如下：

watchEffect(() => {const formProperties = props.activeData.formPropertiesprops.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.readonlyitem.hidden = properties.options.hiddenitem.required = properties.options.required}})
})

5、效果图如下：
