Hi 

I have a button with client side validation function

    <button type="submit" title="Submit" class="btn btn-success btn-sm" onclick="return OnSubmitValidate()">
                            Submit
                        </button>

i want to call asp-page-handler method inside this javascript function .Currently im using AJAX method ,but its not firing the method.

    function OnSubmitValidate() {
            
            var RequestType = document.getElementById("DrpDwnRequestType");
            var RequestTypeValue = RequestType.options[RequestType.selectedIndex].value;
            alert(RequestTypeValue);
            if ((RequestTypeValue == "") || (RequestTypeValue == null)) {
                document.getElementById("ErrRequestType").innerHTML = "Please select Request Type";
                return false;
            }
    
            $.ajax({
                type: 'POST',
                url: rootPath + "/RequestForm?handler=Submit",
                dataType: "json"
            });        
        }

Edit:Submit Handler

    public async Task<IActionResult> OnPostSubmitAsync()
            {
                
                
                BillType = new SelectList(_context.BillType.OrderBy(e => e.ID), "BillTypes", "BillTypes");
    
    
    
                var requestexist = await _context.RequestFormMaster.FirstOrDefaultAsync(c => c.RequestID == RequestFormMaster.RequestID);
    
                RequestAlreadyExist = requestexist;
                if (RequestAlreadyExist != null)
                {
                    return Page();
                }
                else
                {
                    RequestFormMaster.RequestID = RequestFormMaster.RequestID.Trim();
                    
                    RequestFormMaster.LastModifiedBy = HttpContext.Session.GetString("firstname") + " " + HttpContext.Session.GetString("lastname");
                    RequestFormMaster.LastModifiedTimeStamp = DateTime.Now;
    
                    _context.Entry(RequestFormMaster).State = EntityState.Added;
                    await _context.SaveChangesAsync();
                    TempData["ReqSubmitted"] = "Submitted";
                    
                    
                    if (ReqSupportingFiles != null || ReqSupportingFiles.Count > 0)
                    {
                        int i = 0;
                        foreach (IFormFile upload in ReqSupportingFiles)
                        {
                            i++;
                            // Upload file to server folder
                            string ext = Path.GetExtension(upload.FileName).ToLower();
                            if ((ext == ".ppt") || (ext == ".pptx") || (ext == ".xls") || (ext == "xlsx"))
                            {
                                var filesave = Path.Combine(_env.WebRootPath, "Documents", foldername, i + "_" + upload.FileName);
                                using (var stream = System.IO.File.Create(filesave))
                                {
                                    await upload.CopyToAsync(stream);
                                }
                            }
                        }
                    }
                    
                    return RedirectToPage("/RequestSummary");
                }
                //return Page();
    
            }
