There is a button on the view
bool isPayAvailable = GetPaymentButtonEnabled(int statusId); <button id="payButton" @(!isPayAvailable ? "disabled" : string.Empty)>Оплатить</button> There is also a button that changes the statusId parameter. It turns out that in the handler for clicking this button there is a code that changes the attribute for the button "Pay". It turns out that there is duplication of code. The question then is: how to call a controller method from a JS file?
I would create a data attribute in it, write the required url , and in javascript got the value from this attribute and performed the necessary actions.
For example:
<button id="customButton" data-target="@Url.Action("Метод", "Контроллер")" data-target="#content"></button> //здесь будет выведен результат запроса <div id="content"></div> Method in controller
public ActionResult Test(string payId) { //код метода } somewhere in js
$('customBtn').on('click', function(){ var target = $(this).data('target'); var url = $(this).data('url'); var payId = $("#payId").val(). var completeUrl = //склеиваем в итоге может получиться что то типа //TestController/Test?payId=5; $.ajax({ url: completeUrl, success: function (result) { $(target).html(result); } }) }); //дальнейшие действия }); @Html.Hidden("payId", payId) like its overloaded version of HiddenFor() intended to create a field invisible to the user, in this case the record id written there - BaldSource: https://ru.stackoverflow.com/questions/515003/

@(!isPayAvailable ? "disabled" : string.Empty)- this is the same code that sets the on / off state. or I didn't understand the question - Bald@(...code is responsible for this@(..., which, judging by everything, checks for the presence of isPayAvailable and adds the disabled attribute to the button in the absence of the required data - lexxl
