自動bind 

  public IActionResult OnPostModuleOnchange([FromBody] PostData post)
        {

            return new JsonResult(MssqlConn.GetToolIDInfo(post.fab, post.module));
        }
[BindProperties]
  public class PostData
    {
        public string fab { get; set; }
        public string module { get; set; }
        public string tool { get; set; }
    }

ajax 傳下拉式選單的value 

 $('#MODULE').change(function () {
        var fabValue = $('#FAB').find(":selected").val();
        var selectedvalue = $(this).find(":selected").val();
        $.ajax({
            type: "POST",
            url: './SPECAlarmRTTCSetting?handler=ModuleOnchange',
            beforeSend: function (xhr) {
                xhr.setRequestHeader("XSRF-TOKEN", $('input:hidden[name="__RequestVerificationToken"]').val());
            },//razor page 需要驗證
            data: JSON.stringify({
                fab: fabValue,
                module: selectedvalue
            }),
            contentType: 'application/json; charset=utf-8',
            dataType: "json"

        }).done(function (data) {
            var options = '';
            for (var i = 0; i < data.length; i++) {
                options += '<option value="' + data[i].toolid + '">' + data[i].toolid + '</option>';
            }
            $("select#TOOL").html(options);
            console.log(data);
        })
    });

或是

        public IActionResult OnPostFabOnchange(string fab)
        { 
            return new JsonResult(MssqlConn.GetModuleNameInfo(fab));
        }

ajax 

 $('#FAB').change(function () {
        var selectedvalue = $(this).find(":selected").val();
        var data = new FormData();
        data.append('fab', selectedvalue);
        //alert(selectedvalue);
        $.ajax({
            type: "POST",
            url: './SPECAlarmRTTCSetting?handler=FabOnchange',
            beforeSend: function (xhr) {
                xhr.setRequestHeader("XSRF-TOKEN", $('input:hidden[name="__RequestVerificationToken"]').val());
            },
            processData: false,
            contentType: false,
            data: data,
            dataType: "json"
        }).done(function (data) {
            var options = '';
            for (var i = 0; i < data.length; i++) {
                options += '<option value="' + data[i].modulename + '">' + data[i].modulename + '</option>';
            }
            $("select#MODULE").html(options);
            console.log(data);
        })
    });

 

手刻取出ajax post 值 

            string module = "";
            MemoryStream stream = new MemoryStream();
            Request.Body.CopyTo(stream);
            stream.Position = 0;
            using (StreamReader reader = new StreamReader(stream))
            {
                string requestBody = reader.ReadToEnd();
                if (requestBody.Length > 0)
                {
                    var obj = JsonConvert.DeserializeObject<PostData>(requestBody);
                    if (obj != null)
                    {
                        fab = obj.fab;
                        module = obj.module;
                    }
                }
            }
