通过 Javascript，我对控制器进行 ajax 调用以更新实体“Owner”。控制器使用服务来处理请求，并相应地更新实体。在服务更新方法中我还更新了“Owner”的相关数据，并且在某些情况下我还添加了一个新的实体“Owner”。
问题
这里（在服务中），由于某种原因，
updateThreadPool如果我只执行
EDIT如果我执行 ADD 操作，然后执行 EDIT 操作，则编辑将运行 2 次，在数据库中再添加 2 行。
如果我执行 2 次或更多（让我们称这个数字为 N）ADD 操作，然后执行编辑操作，则编辑将运行 N x 2 次，创建 N x 2 重复行。
我尽可能地减少了代码。它有点长，但我不想排除任何可能实际上是罪魁祸首的情况。
如果提供的最小化代码还不够，我还可以为我们之间的代码向导提供对存储库的访问。请帮我。我真的不知道还有什么可以尝试让它发挥作用。
使用的堆栈：.NET Core 2.2、最新的 jQuery、MySQL、pomelo、EF Core
我已经尝试过的东西：
ScopedTransientTransientthreadPool.MaxLimit(1,1)前端：
<script>
$(document).one("click", "#buttonId", function () {
$(this).attr("disabled", "disabled");
var result = validator.validate(validator);
if (result.formIsValid) {
$.ajax({
type: "POST",
url: "/controllerName/Edit",
data: $('#editForm').serialize(),
dataType: "json",
success: function (response) {
CloseModalById('editModal');
ShowHeaderAlert(response, "success", 5000);
$('#ownerListState').change();
},
error: function (error) {
CloseModalById('editModal');
swalErrorTimer(error.responseText, 7000);
}
});
} else {
updateUi(result.validationResults, "form-group", "error_span");
}
});
</script>
控制器：
public OwnerController(IOwnerService ownerService,IMapper mapper)
{
_ownerService = ownerService;
_mapper = mapper;
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult EditModal(OwnerViewModel ownerVM)
{
try
{
var dto = _mapper.Map<OwnerDto> ownerVM);
var result = _ownerService.UpdateOwner(dto);
if (result.Successful)
{
return Ok(JsonConvert.SerializeObject("Successfully updated!"));

所有存储库内的更新和添加方法都是类似的。
示例：
public Entity UpdateEntity(Entity entityToUpdate)
{
_db.EntityDbSet.Update(entityToUpdate);
_db.SaveChanges();
return entityToUpdate;
}
public Entity AddEntity(Entity entityToAdd)
{
_db.EntityDbSet.Add(entityToAdd);
_db.SaveChanges();
return entityToAdd;
}
问题出在 HTML 文件中。包含模式的部分视图也加载了 js 文件，因此它加载了多次。这就是多个电话的来源。为了使其工作，我在 Index.js 中加载了 js 文件。对于一个疯狂问题的简单解决方案却带来了疯狂的结果......
