如图，点击新增的时候自动获取当前的时间来作为创建时间

时间组件：

      <el-form-item label="创建时间" prop="createTime">
        <el-date-picker
          v-model="createTime"
          type="datetime"
          value-format="x"
          placeholder="选择创建时间"
        />
      </el-form-item>

formData：

const formData = ref({
  id: undefined,
  courseType: undefined,
  subject: undefined,
  fileType: undefined,
  appendixName: undefined,
  creator:  userStore.user.id,
  createTime: undefined,
})

const createTime = ref('')

打开弹窗时给创建时间赋值：

/** 打开弹窗 */
const open = async (type: string, id?: number) => {
  createTime.value = dateFormat()
  dialogVisible.value = true
  dialogTitle.value = t('action.' + type)
  formType.value = type
  resetForm()
  userList.value = await UserApi.getSimpleUserList()
  // 修改时，设置数据
  if (id) {
    formLoading.value = true
    try {
      formData.value = await ResearchingManageApi.getResearchingManage(id)
     formData.value.createTime = createTime.value

    } finally {
      formLoading.value = false
    }
  }
  // 获得登录人名称
  userList.value = await UserApi.getSimpleUserList()
  userList.value.forEach((item) => {
    if (item.id === userStore.user.id) {
      creator.value = item.nickname
    }
  })
}

获取时间方法：

const dateFormat = ()=>{
  let date = new Date();
      let y = date.getFullYear();
      let MM = date.getMonth() + 1<10? ('0' + (date.getMonth() + 1)) : date.getMonth() + 1;
      let d = date.getDate()< 10 ? ('0' + date.getDate()) :  date.getDate()
      let h = date.getHours() < 10 ? ('0' +date.getHours()) : date.getHours();
      const m = date.getMinutes()< 10 ? ('0' + date.getMinutes()) : date.getMinutes();
      let s = date.getSeconds() < 10 ? ('0' +date.getSeconds()) : date.getSeconds();
      console.log( y + '-' + MM + '-' + d + ' ' + h + ':' + m  + ':' +s)
      return  y + '-' + MM + '-' + d + ' ' + h + ':' + m  + ':' +s
}
