$.ajax({

I use almost the same codes:

}

<hr />
<form id="myForm">

#section scripts {

$.ajax({

url: "/Home/Contact",
data: data,
success: function (response) {

}
The id could be passed to the controller.
Could you show the debug view in the controller?

How Can change to my code that if a new Publisher inserted to Database, the Publisher dropdown refresh and select newly inserted data as a selected item?
About question
I can't run your code locally.
These operations can be implemented through JS.
I can show my tools.
This is the function gif:
Solution:
Select and add options as a whole.
// index.cshtml
<div>
#await Component.InvokeAsync("AutoAddListValue")
</div>
//Component
#model List<string>
<h3>Default page</h3>
<div>
<div>
<p>Lists</p>
<select name="select" class="" id="ComponentSelectId" onclick="ComponentSelectClick()">
<option id="ComponentOptionId" style="width:auto">ComponentTest</option>
#if (Model.Count != 0)
{
int count = Model.Count();
for (int item = 0; item < count; item++)
{
<option id="option">#Model[item].ToString()</option>
}
}
</select>
</div>
<div>
<input id="ComponentTestJsInput" class="d-none" value="132323" type="text" />
<input id="ComponentBtnDisplay" value="Add" type="button" class="btn btn-primary" onclick="ComponentBtnDisplayClick()">
<input id="ComponentBtnAdd" value="Add" type="button" class="btn btn-primary d-none" onclick="ComponentBtnAddClick()">
</div>
</div>
Bind data for components.
public class AutoAddListValueViewComponent : ViewComponent
{
private readonly SchoolContext _context;
public AutoAddListValueViewComponent(SchoolContext context)
{
_context = context;
}
public async Task<IViewComponentResult> InvokeAsync(
int maxPriority, bool isDone)
{
string MyView = "Default";
var items = await GetListAsync();
return View(MyView, items);
}
public async Task<List<string>> GetListAsync()
{
return await _context.Test.Select(o => o.Name).ToListAsync();
}
}
Using JS code to realize page interaction.
var ComponentBtnDisplayClick = function () {
$('#ComponentBtnAdd').removeClass("d-none");
$('#ComponentTestJsInput').removeClass("d-none");
$('#ComponentBtnDisplay').addClass("d-none");
}
var ComponentBtnAddClick = function () {
//alert("666666");
$('#ComponentBtnAdd').addClass("d-none");
$('#ComponentTestJsInput').addClass("d-none");
$('#ComponentBtnDisplay').removeClass("d-none");
inputVal = $('#ComponentTestJsInput').val();
//alert(inputVal);

Display value from controller based on two dropdown selection on the view(when select both of them at the same time). MVC asp.net

On the product output insert page, when user select from two dropdown lists(depoId and materialId) at the same time, I would like to display the stock quantity (stockAmount) of the product with the help of material id and the depot id. I do not know how I display on the view part and how I write based on two dropdownlist selection.

use ajax to send these id to controller

byte.TryParse(coll["Sort"], out sort);
bool.TryParse(coll["Mandatory"], out mandatory);
question.QuestionTypeId = qid;
question.Sort = sort;
question.Mandatory = mandatory;
foreach (var answer in coll["Answers"])
question.Answers.Add(new Models.Answer() { Value = answer + "" });
if (question != null)
{
if (BLL.Questions.Insert(question) != null)
ViewBag.Message = "Successfully inserted";
else
ViewBag.Message = "Insert could not be done";
return RedirectToAction("Index", "Question", new { questionId = question.QuestionId });
}
}
return View();
}
When (+) clicked
$('#allAnswers').append(
'<div class="input-group col-lg-4">' +
'<input class="form-control" name="Answers"> ' +
'<div class="input-group-btn">' +
' <button type="button" class="btn btn-default removeAnswer"><span class="glyphicon glyphicon glyphicon-trash" aria-hidden="true"></span></button>' +
'</div> </div>');
As discussed.. here is how i would approach this.
I have a view model to hold the questions and answers and the selected question to which we will be adding answers.
public class CurrentViewModel
{
public string QuestionSelected { get; set; }
public List<SelectListItem> Questions { get; set; }
public List<string> Answers { get; set; }
}
Then in your controller we have an action to return the view, an action to get the answers for the selected question, an action to add a new answer for the selected question and also a save method which just demonstrates the final model content posted.
public class TestController : Controller
{
public ActionResult Test()
{
var model = new CurrentViewModel()
{
Questions = new List<SelectListItem>()
{
new SelectListItem()
{
Text = "Question 1",
Value = "Question 1"
},
new SelectListItem()
{
Text = "Question 2",
Value = "Question 2"
}
},
Answers = new List<string>()
};
return View("Test", model);
}
public PartialViewResult GetAnswers(CurrentViewModel model)
{
model.Answers = new List<string>();
//model.Answers = Get Answers from some service based on QuestionSelected?!
model.Answers.Add("Answer 1");
model.Answers.Add("Answer 2"); //Add manuall for example
return PartialView("_Answers", model);
}
public PartialViewResult AddAnswer(CurrentViewModel model)
{
model.Answers.Add("Add answer here...");
return PartialView("_Answers", model);
}
public ActionResult SaveQuestionsAndAnswers(CurrentViewModel model)
{
if (model.Questions.Count == 0)
{
}
return View("Test", model);
}
}
Then we have a main view for showing the questions dropdown and a partial view that will show us the answers.
Main View
#model TestMVC.Models.CurrentViewModel
#{
ViewBag.Title = "Test";
}
<link href="~/Content/StyleSheets/jquery-ui.css" rel="stylesheet" />
<script src="~/Content/Scripts/jquery-2.2.3.js"></script>
<script src="~/Content/Scripts/jquery-ui-1.11.4.js"></script>
<div id="divBodyContent">
<div>
<h3>Q & A</h3>
</div>
#using (Html.BeginForm("SaveQuestionsAndAnswers", "Test", FormMethod.Post, new { id = "frmQandA" }))
{
#Html.Label("lblQ", "Questions", new { #class = "form-control inline" })
#Html.DropDownListFor(model => model.QuestionSelected, Model.Questions, "Select--", new { #class = "form-control inline", id="ddQuestions" })
<div id="divAnswers">
#Html.Partial("_Answers")
</div>
<div style="margin-top: 1%;">
<button id="btnSave" type="submit" class="btn btn-primary" style="margin-left: 4px; margin-bottom: 10px; width: 7%">save</button>
</div>
}
</div>
<script>
$("#ddQuestions").on("change", function() {
var myData = $('#frmQandA').serialize();
$.ajax({
type: "POST",
url: "#Url.Action("GetAnswers", "Test")",
data: myData,
contentType: 'application/x-www-form-urlencoded; charset=UTF-8',
success: function(data) {
$("#divAnswers").html(data);
}
})});
</script>
Partial View
#model TestMVC.Models.CurrentViewModel
<link href="~/Content/StyleSheets/jquery-ui.css" rel="stylesheet" />
<script src="~/Content/Scripts/jquery-2.2.3.js"></script>
<script src="~/Content/Scripts/jquery-ui-1.11.4.js"></script>
<div>
#for (var counter = 0; counter <= (Model.Answers.Count - 1); counter++)
{
#Html.TextBoxFor(model => model.Answers[counter], new {#class = "form-control inline"})
}
<div style="margin-top: 1%;">
<button id="btnAddAnswer" type="button" class="btn btn-primary" style="margin-left: 4px; margin-bottom: 10px; width: 7%">Add</button>
</div>
</div>
<script>
$("#btnAddAnswer").on("click", function() {
var myData = $('#frmQandA').serialize();
$.ajax({
type: "POST",
url: "#Url.Action("AddAnswer", "Test")",
data: myData,
contentType: 'application/x-www-form-urlencoded; charset=UTF-8',
success: function (data) {
$("#divAnswers").html(data);
}
})});
</script>
I've tested this locally and it works. In a nutshell, when we need a new answer adding to the model, we add it in server side so we can then bind to the model in the browser. We do this via an Ajax call on the change event of the questions drop down. The partial view iterates through each answer via a counter which generates a unique id and textbox for each answer. Adding a new answer is also achieved via ajax. These can then all be posted back.
Hope that helps.
