抽成一个公共方法 const formData = new FormData; formDataappendfile thisimportAssesseesfile; formDataappendactivityInstanceId thisactivityId; formDataappendappraiseType 1;使用jsformDataappen

function appendFormData(formData, data) { for (let key in data) { formData.append(key, data[key]); } }

const formData = new FormData(); const data = { file: this.importAssesseesfile, activityInstanceId: this.activityId, appraiseType: 1 };

appendFormData(formData, data);
