在接口返回数据后，给动态表单复制遇到个这么个问题，第一次点编辑时，会报下图中的错误，但第二次点击编辑就不报错了，之后也是正常的。
解决：首先保证表单返回数据与注册数据都对应，给表单赋值放在了this.$nextTick，这两点没没问题了，可以往下看了。

部分代码：

  edit(record) {this.editId = record.Idthis.form.resetFields()//第二种办法：先注册keys//  this.form.getFieldDecorator('keys', { initialValue: [0], preserve: true })this.modalState = '编辑'this.requestGet('/Examtion/GetExamtionById', { id: this.editId }).then((res) => {console.log(res.data.QuestionTemplateList.map((item) => {return {QuestionStyle: item.QuestionStyle,QuestionNum: item.QuestionNum,Score: item.Score,}}))const validTime = [moment(res.data.StartTime, 'YYYY-MM-DD HH:mm:ss'),moment(res.data.EndTime, 'YYYY-MM-DD HH:mm:ss'),]const TreeIds = res.data.Regions.length == 0 ? [] : res.data.Regions[0].TreeIds.split(',')if (TreeIds.length == 0) {} else {TreeIds.splice(0, 2)}// 第一种办法：初始化keys值this.form.getFieldDecorator('keys', {initialValue: res.data.QuestionTemplateList.map((item, index) => index),preserve: true, //即便字段不再使用，也保留该字段的值})//第二种办法：再给keys赋值，this.visible = true写在哪里就都可以了// this.form.setFieldsValue({//   keys: res.data.QuestionTemplateList.map((item, index) => index),// })id = res.data.QuestionTemplateList.length//第一种办法：关键点是这里在表单赋值前，令this.visible = true，也就是modal 弹出this.visible = truethis.$nextTick(() => {this.form.setFieldsValue({// keys:res.data.QuestionTemplateList.map((item, index) => index),ExamtionName: res.data.ExamtionName,GrossScore: res.data.GrossScore,ExamtionDuration: res.data.ExamtionDuration,QualifiedScore: res.data.QualifiedScore,Version: res.data.QuestionTemplateList[0].QuestionVersons,RegionId: TreeIds,validTime: validTime,// Json: res.data.QuestionTemplateList.map((item) => {//   return {//     QuestionStyle: item.QuestionStyle,//     QuestionNum: item.QuestionNum,//     Score: item.Score,//   }// }),QuestionNum: res.data.QuestionTemplateList.map((item) => item.QuestionNum),})})})},

完美解决！欢迎大佬指正！
