ViewsJS+ASP Net Core Get data from controller
the question arose: How to get data from the controller in asp net core using js? I tried to send a post request head-on, but it seems to me there is a more elegant solution At the same time, I need this to happen when the html of the Select element changes I wrote a script that changes the field when the select changes
function Change_Aud() {
var x = document.getElementById("Levelid").value;
document.getElementById("Hardware_La").value = x ;
}
Controller example
public async Task<IActionResult> Get_Hardware_Unit(int id)
{
Level level = _context.Levels.Where(p => p.Number == id.ToString()).First();
return Content(level.Public_Hardware.ToString());
}

Test page code in cshtml:
@{
ViewData["Title"] = "Home Page";
int count = 5;
}
<script src="https://code.jquery.com/jquery-2.2.4.js" integrity="sha256-iT6Q9iMJYuQiMWNd9lDyBUStIq/8PuOW33aOqmvFpqI=" crossorigin="anonymous"></script>
<script>
function myFunction(selectObject) {
var value = selectObject.value;
$("#selectnum").html(value);
backendfunc(value);
}
function backendfunc(value) {
$.ajax({
url: "/Test/Get_Hardware_Unit",
type: "GET",
data: { id: value },
success: function (res) {
$("#convertnum").html(res);
},
error: function (hata, ajaxoptions, throwerror) {
$("#convertnum").html("convert failed");
}
});
}
</script>
<div>
<select name="num" id="num-select" onchange="myFunction(this)">
<option value="">--Please choose an option--</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
</div>
<br />
<br />
<div>
You select value is : <span id="selectnum"></span>
</div>
<br />
<br />
<div>
After backend converted, here is : <span id="convertnum"></span>
</div>
My function in Controller:
public async Task<IActionResult> Get_Hardware_Unit(int id) {
string result = string.Empty;
if (id == 1) {
result = "①";
}
if (id == 2)
{
result = "②";
}
if (id == 3)
{
result = "③";
}
return Content(result);
}
