How I Can change value last working date input text without using subm

I work on asp.net MVC . I need to update last working date

based on request no when value Last working date changed .

I need to using ajax jQuery to do that

Web API I will call it using jQuery ajax is Resignation/Edit

Resignation is controller and Edit is action and I will pass

object to Edit action result include request no and last working date .

my code as below :

public class ResignationRequester
{
    [Display(Name = "Request No")]
    public int RequestNo { get; set; }


    [Required]
    [Display(Name = "Last Working Day: ")]
    [DataType(DataType.Date, ErrorMessage = "Date only")]
    [DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]
    public DateTime LastWorkingDate { get; set; }
}

//post
  [ValidateAntiForgeryToken]
  public async Task Edit(ResignationRequester req)
  {
//UPDATE last working date based on Request No
  }

@model HR.WorkforceRequisition.Models.ResignationRequester

@{
    ViewBag.Title = "Details";
    Layout = "~/Views/Shared/_LayoutResignation.cshtml";
}
    

        
            
                
                    @Html.LabelFor(model => model.RequestNo, htmlAttributes: new { @class = "control-label col-md-5" })
                    
                        @Model.RequestNo
                    
                
            

           
         
     
     
         
             @Html.LabelFor(model => model.LastWorkingDate, htmlAttributes: new { @class = "control-label col-md-5" })
             
               
                 @Html.EditorFor(model => model.LastWorkingDate, new { htmlAttributes = new { @class = "form-control" } })

[HttpPost] [ValidateAntiForgeryToken] public ActionResult Edit(ResignationRequester req) { try { // Your logic to update the Last Working Date based on Request No // Assuming you have some data context to work with (e.g., Entity Framework) using (YourDbContext db = new YourDbContext()) { var resignation = db.Resignations.SingleOrDefault(r => r.RequestNo == req.RequestNo); if (resignation != null) { resignation.LastWorkingDate = req.LastWorkingDate; db.SaveChanges(); } else { // Handle the case where the requested Request No is not found. return Json(new { success = false, message = "Request No not found." }); } } return Json(new { success = true, message = "Last Working Date updated successfully." }); } catch (Exception ex) { // Handle exceptions or errors return Json(new { success = false, message = "An error occurred while updating the Last Working Date." }); } }
