MVC button save button not working, button does nothing

I am trying to append an item to the SQL table but when I press the save button nothing happens. The reset button works but not the Save. Nothing is showing in the database either. Basically, I don't understand why the buttons act as if there was no code attached to it. No Error message or crash shows up either.
View
#model BudgetAmazon.ViewModel.ItemViewModel

ViewBag.Title = "Item";
}

<script type="text/javascript">
$(document).ready(function () {
$("#btnSave").click(function () {

$("#ItemCode").val("");
$("#ItemName").val("");
$("#Description").val("");
$("#ItemPrice").val("0");

}
function SaveItem() {

I think the problem is you have made a typo mistake while giving the forma data. Try changing "formDate" to "formData". I have attached the picture to show where to.
enter image description here

As far as I know, your url may require something like .html file extension. Try to revise like url: "/Item/index.html, and see if the request success or not.

Cascading dropdown list does not bind data to the 2nd dropdown

I have a main view. Once the posting is done, it will render a partial view in the main view.
My partial view has a cascading dropdown list that changes the 2nd DropdownList items based on the selected value from the 1st DropdownList.
Here is my Dropdown in my Partial View.
#model MigratingDB.Models.ViewModel
<script src="~/Scripts/jquery-1.10.2.js"></script>
<script src="~/Scripts/jquery.unobtrusive-ajax.js"></script>
<div>
#Html.DropDownListFor(m => m.DropdownViewModel.SelectedValue1,
Model.DropdownViewModel.List1, "Select",htmlAttributes: new { #class = "form-control", #id = "ddl1" })
</div>
<div>
#Html.DropDownListFor(m => m.DropdownViewModel.SelectedValue2,
Model.DropdownViewModel.List2 = new SelectList(Enumerable.Empty<SelectListItem>()), "Select",
htmlAttributes: new { #class = "form-control", #id = "ddl2" })
</div>
The script I tried based from this.
<script>
$(function () {
$('#ddl1').change(function () {
$("#ddl2").empty();
var selectedValue = $(this).val();
$.ajax({
url: '#Url.Action("Getddl2Items", "Controller")',
type: "POST",
dataType: 'json',
data: { id: selectedValue },
success: function (value) {
$.each(value, function (i, val) {
$("#ddl2").append('<option value="' + val.Value + '">' +
val.Text + '</option>');
});
},
error: function (ex) {
alert('Failed' + ex);
},
});
});
});
</script>
In my Controller:
[HttpPost]
public ActionResult Foo (ViewModel vm)
{
// Dropdownlist
var list1 = // get items frop ddl1
vm.DropdownViewModel.List1= new SelectList(list1, "Value", "Text");
return PartialView("_PartialView", vm);
}
// Get ddl2 Items
public JsonResult Getddl2Items (int id)
{
var ViewModel = new ViewModel();
var list2= // get ddl2 items from the database
ViewModel.DropdownViewModel.List2= new SelectList(list2, "Value", "Text");
return Json(ViewModel.DropdownViewModel.List2, JsonRequestBehavior.AllowGet);
}
Every time I tried to select a value from the ddl1, it errors and show
Failed [object Object].
What causes this?

This is a long post that I tested and works. Since it is long, you can pick out the parts you need. Let's work together to figure out why it is not working for you.
This will be your table and data creation:
--Use your database name instead of Breaz
USE [Breaz]
GO
/****** Object: Table [dbo].[tblCity] Script Date: 7/17/2017 9:46:31 AM ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[tblCity](
[Cityid] [int] NOT NULL,
[CityName] [nvarchar](50) NULL,
[stateid] [int] NOT NULL
) ON [PRIMARY]
GO

Create your edmx, by going through visual studio wizard.
Create your view model:
//user your namespace
namespace Testy20161006.Models
{
public class Registration
{
[Required(ErrorMessage = "Enter State")]
public string State { get; set; }
[Required(ErrorMessage = "Enter City")]
public string City { get; set; }
}
}
Your controller/classes:
public class HomeController : Controller
{
public JsonResult getCity(int id)
{
//use your dbcontext name from edmx wizard
using (BreazEntities33 objEF = new BreazEntities33())
{
var ddlCity = objEF.tblCities.Where(x => x.stateid == id).ToList();
List<SelectListItem> licities = new List<SelectListItem>();
licities.Add(new SelectListItem { Text = "--Select State--", Value = "0" });
if (ddlCity != null)
{
foreach (var x in ddlCity)
{
licities.Add(new SelectListItem { Text = x.CityName, Value = x.Cityid.ToString() });
}
}
return Json(new SelectList(licities, "Value", "Text", JsonRequestBehavior.AllowGet));
}
}
[HttpPost]
public ActionResult IndexStackOverflow(Registration registration)
{
//put breakpoint here to see values coming back from view
return View(registration);
}
//use your name of action that starts the process, named in routeconfig.cs
public ActionResult IndexStackOverflow()
{
bindState();
return View();
}
public void bindState()
{
//use your dbcontext name from edmx wizard
using (BreazEntities33 objEF = new BreazEntities33())

li.Add(new SelectListItem { Text = "--Select State--", Value = "0" });
foreach (var m in state)
{
li.Add(new SelectListItem { Text = m.statename, Value = m.stateid.ToString() });
ViewBag.state = li;

Here is an example that returns Json value from a SelectListItem in a ViewModel.
public class ReturnJsonVM
{
public List<SelectListItem> licities = new List<SelectListItem>();
}
public class HomeController : Controller

//use your name of action that starts the process, named in routeconfig.cs
public string IndexStackOverflow()

{
var ddlCity = objEF.tblCities.Where(x => x.stateid == 1).ToList();
List<SelectListItem> licities = new List<SelectListItem>();
ReturnJsonVM returnJsonVM = new ReturnJsonVM();
if (ddlCity != null)
{
foreach (var x in ddlCity)
{
returnJsonVM.licities.Add(new SelectListItem { Text = x.CityName, Value = x.Cityid.ToString() });
}
}
string json = JsonConvert.SerializeObject(returnJsonVM.licities);
//put your break point here to see example that return Json value from SelectListItem in ViewModel
return json;
}

when i click on google map,i get lat & lng as below:
and i have some submit textbox and fill those.

<div class="col-md-10">
#Html.EditorFor(model => model.Job.PickUpAddress.Lat, new { htmlAttributes = new { #class = "form-control", id = "pickLat", #value = "" } })

jQuery code doesn’t work properly after submitting Ajax.BeginForm in asp.net mvc

I tried to minimize huge problem to a small one so I created the new sample web project; mvc-empty in VS. I created one view named „Index” in Home controller. Index view code:
#model WebApplication16.ViewModels.Home.IndexVM
#{
ViewBag.Title = "Index";
}
#Html.Partial("~/Views/Home/_Orders.cshtml", Model.Orders)
#section scripts{
<script src="~/Scripts/jquery.validate.js"></script>
<script src="~/Scripts/jquery.validate.unobtrusive.js"></script>
<script src="~/Scripts/jquery.unobtrusive-ajax.js"></script>
<script>
$("#Type").change(function () {
$('#order-current > img').remove();
var currentOrder = "#Type_" + $("#Type").find('option:selected').text();
var $img = $(currentOrder).clone();
$img.removeClass("hidden");
$("#order-current").append($img);
$("#ajax-form").submit();
});
</script>
}
Home controller code:
public class HomeController : Controller
{
[HttpGet]
public ActionResult Index()
{
IndexVM dataVM = new IndexVM();
GetControlsDataSource(dataVM.Orders);
return View(dataVM);
}
private static void GetControlsDataSource(OrdersVM dataVM)
{
List<SelectListItem> typeControlDataSource = new List<SelectListItem>();
foreach (var en in Enum.GetValues(typeof(TypeEnum)))
{
SelectListItem item = new SelectListItem();
item.Text = en.ToString();
item.Value = ((int)en).ToString();
typeControlDataSource.Add(item);
}
dataVM.TypeControlDataSource = typeControlDataSource;
}
[HttpPost]
public ActionResult Pay(IndexVM dataVM)
{
GetControlsDataSource(dataVM.Orders);
if (ModelState.IsValid)
{
dataVM.Orders.Info = "Info bla bla bla";
return PartialView("~/Views/Home/_Orders.cshtml", dataVM.Orders);
}
else
{
return View(dataVM);
}
}
}
There is also a partial view named “_Orders”, which is rendered on the Index view.The code of _Orders partial view:
#model WebApplication16.ViewModels.Home.OrdersVM
#using (Ajax.BeginForm("Pay", "Home", new AjaxOptions
{
InsertionMode = InsertionMode.Replace,
UpdateTargetId = "result",
}, new { id = "ajax-form" }))
{
<div id="result">
<div id="order-current">
</div>
<div>
#Html.TextBoxFor(x => x.Name, new { #class = "form-control", style = "margin-top:10px;", id = "Name" })
#Html.ValidationMessageFor(x => x.Name)
</div>
<div>
#Html.DropDownListFor(x => x.Type, Model.TypeControlDataSource, new { #class = "form-control", style = "margin-top:10px;", id = "Type", })
#Html.ValidationMessageFor(x => x.Type)
</div>
<div>
<p>#Model.Info</p>
</div>
<button type="submit" class="btn btn-primary" name="ok"> OK</button>
</div>
}
<div id="orders-container">
<img id="Type_I" src="~/App_Images/Type_I.png" class="img-responsive hidden" />
<img id="Type_II" src="~/App_Images/Type_II.png" class="img-responsive hidden" />
<img id="Type_III" src="~/App_Images/Type_III.png" class="img-responsive hidden"/>
</div>
Index model is described by class IndexVM:
public class IndexVM
{
public IndexVM()
{
this.Orders = new OrdersVM();
}
public OrdersVM Orders { get; set; }
}
_Orders model is described by class OrdersVM:
public class OrdersVM
{
[Required]
public string Name { get; set; }
public string Info { get; set; }
[Required]
public TypeEnum Type { get; set; }
public List<SelectListItem> TypeControlDataSource { get; set; }
}
public enum TypeEnum
{
I,
II,
III
}
After change of value in DropDownListFor control with id=”Type”, the picture from hidden field should be injected by jquery code located in Index view into container with id=”order-current” and after that operation the ajax-form should be submitted. It works properly but after calling
return PartialView("~/Views/Home/_Orders.cshtml", dataVM.Orders);
from the HomeController, the field Info is updated properly but the injected picture from the “order-current” div container is gone. I tried to see what’s wrong in Google Chrome using F12 button and there are no errors but appeared an infinite loop in “browserLink” script. I can’t explain why.
All I want is to see the injected picture in container with id=”order-current after submitting the ajax-form. How to do this and what I did wrong?

Thanks to my friend I finally solved the problem. After updating the “result” container, all events added by jQuery to controls located in this container are unpinned. That’s why it crashes.
The way to make it work correctly is to create a function and pin it to the event OnComplete of AjaxBeginForm. After each update of the result container via ajax, this function is called. I also made a small mistake in Home controller because I inserted a wrong view model class. After all changes, it looks like this;
Home controller code:
public class HomeController : Controller
{
[HttpGet]
public ActionResult Index()
{
IndexVM dataVM = new IndexVM();
GetControlsDataSource(dataVM.Orders);
return View(dataVM);
}
private static void GetControlsDataSource(OrdersVM dataVM)
{
List<SelectListItem> typeControlDataSource = new List<SelectListItem>();
foreach (var en in Enum.GetValues(typeof(TypeEnum)))
{
SelectListItem item = new SelectListItem();
item.Text = en.ToString();
item.Value = ((int)en).ToString();
typeControlDataSource.Add(item);
}
dataVM.TypeControlDataSource = typeControlDataSource;
}
[HttpPost]
public ActionResult Pay(OrdersVM dataVM)
{
GetControlsDataSource(dataVM);
if (ModelState.IsValid)
{
dataVM.Info = "Info bla bla bla";
return PartialView("~/Views/Home/_Orders.cshtml", dataVM);
}
else
{
return View(dataVM);
}
}
}

The problem is this line in your controller:
ViewData["guia"] = new SelectList(
db.TblGuias.Where(g => g.fechaRecepcionGuia == null).Select((g => g.numeroGuia)),
"numeroGuia", "companiaEnvios","destino","pesoGuia","fechaEnvioGuia");
You are not specifying the constructor parameters for SelectList properly. There are several different overloads, but I think the one you want is this one:
public SelectList(
IEnumerable items,
string dataValueField,
string dataTextField
)
The first parameter, items, represents the list of items that you want be rendered into <option> tags inside the <select>.
The second parameter, dataValueField, is the name of the property on the items in the enumerable which will become the value attribute inside each <option> tag.
Similarly, the third parameter, dataTextField, is the name of the property which will become the text displayed for each <option>.
So, if you change your code to the following, I think it should work:
ViewData["guia"] = new SelectList(
db.TblGuias.Where(g => g.fechaRecepcionGuia == null), "numeroGuia", "numeroGuia");
If you want different text to display in the dropdown list, change the third parameter to a different property from your TblGuias class.
