jquery - 使用 ajax Post 编辑数据

Question

我尝试更改表单中的数据然后保存。它没有更改而是添加了一条记录..

这是我的脚本:

$('#UpdateObject').click(function () {

    var ObjnameEntered = $("#NameOB")[0].value;
    var BasenameEntered = $("#selbaseID")[0].value;
    var idsave = $("#labelobID")[0].value;
    var kaartX = $("#mapx")[0].value;
    var kaartY = $("#mapy")[0].value;
    var picture = $("#trainpicname")[0].value;
      $.ajax({
        url: '/api/Traininglocation/' + idsave +'/',
        type: 'POST',
        contentType: 'application/json; charset=utf-8',
        data: JSON.stringify({ TrainLocationName: ObjnameEntered, TrainBaseID: BasenameEntered, TrainXcoord: kaartX, TrainYcoord: kaartY, TrainPicture: picture }),
        dataType: 'json',
        success: $('#doebam').show()
    });
});

Controller :我使用了 put 方法，然后在发布我的项目后收到 405 错误..

//PUT api/Traininglocation/5

    public HttpResponseMessage PutTrainLocation(int id, TrainLocation trainlocation)
    {
        if (ModelState.IsValid && id == trainlocation.id_trainlocation)
        {
            db.TrainLocation.Attach(trainlocation);
            db.ObjectStateManager.ChangeObjectState(trainlocation, EntityState.Modified);

            try
            {
                db.SaveChanges();
            }
            catch (DbUpdateConcurrencyException)
            {
                return Request.CreateResponse(HttpStatusCode.NotFound);
            }

            return Request.CreateResponse(HttpStatusCode.OK);
        }
        else
        {
            return Request.CreateResponse(HttpStatusCode.BadRequest);
        }
    }

    // POST api/Traininglocation
    public HttpResponseMessage PostTrainLocation(TrainLocation trainlocation)
    {
        if (ModelState.IsValid)
        {
            db.TrainLocation.AddObject(trainlocation);
            db.SaveChanges();

            HttpResponseMessage response = Request.CreateResponse(HttpStatusCode.Created, trainlocation);
            response.Headers.Location = new Uri(Url.Link("DefaultApi", new { id = trainlocation.id_trainlocation }));
            return response;
        }
        else
        {
            return Request.CreateResponse(HttpStatusCode.BadRequest);
        }
    }

谁能帮助我？

我改变了我的 Controller :其中 PutTrainLocation 为 PostTrainLocation。感谢您的回复!

    public HttpResponseMessage PostTrainLocation(int id, TrainLocation trainlocation)
    {
        if (ModelState.IsValid && id == trainlocation.id_trainlocation)
        {
            db.TrainLocation.Attach(trainlocation);
            db.ObjectStateManager.ChangeObjectState(trainlocation, EntityState.Modified);

            try
            {
                db.SaveChanges();
            }
            catch (DbUpdateConcurrencyException)
            {
                return Request.CreateResponse(HttpStatusCode.NotFound);
            }

            return Request.CreateResponse(HttpStatusCode.OK);
        }
        else
        {
            return Request.CreateResponse(HttpStatusCode.BadRequest);
        }
    }
