附上最后成功实现的代码： const currentData = this.$('tableField_liyfl2t2').getValue(); const batchFetchLoading = this.utils.toast({ title: `处理中，请不要关闭浏览器，预计需要 ${Math.ceil(value.length / 5)} 秒`, type: 'loading' }); try { const batchFetchResult = await Promise.all( value.map(async (form) => { const res = await this.dataSourceMap.getDataById.load({ formInstId: form.instanceId }); return res || {}; }) ); batchFetchLoading(); const newData = batchFetchResult.map((item) => { const { formData = {} } = item; const existingData = currentData.find((data) => data && data._id === item.formInstId); if (existingData) { // 数据项已存在，不填充任何字段 return existingData; } else { // 数据项不存在，创建新行并填充所有字段 return { _id: item.formInstId, textField_liyfl2t6: formData.textField_lhyfrduh || '', textField_liyfl2t3: formData.textField_lha93y6t || '', textField_liyfl2t4: formData.textField_lha93y6u || '', textField_liyfl2t5: formData.textField_lha93y6v || '', numberField_liyfl2ta: formData.numberField_lha93y6y || 0, numberField_liyfl2tb: (formData.numberField_lhabu22e || 0) * (formData.numberField_lha93y6y || 0), numberField_liyfl2td: formData.numberField_lhbsvhio || 0, numberField_liyfl2tc: (formData.numberField_lhbsvhio || 0) * (formData.numberField_lhabu22e || 0), numberField_liyfl2t9: formData.numberField_lhabu22e || 0, numberField_lj3luf14: formData.numberField_lhabu22e || 0, textField_liyfl2t7: formData.textField_lgq6n9dz || '', textField_liyibdac: formData.textField_lha93y6w || '' }; } }); this.$('tableField_liyfl2t2').setValue(newData); } catch (error) { batchFetchLoading(); this.utils.dialog({ method: 'alert', title: '处理出错', content: '请求关联数据失败。', onOk: () => { }, onCancel: () => { } }); } }
