get value from a hidden field in mvc view, value already set

Question

@Html.Hidden("cinDays") 

From inspect element:

<input id="cinDays" name="cinDays" type="hidden" value="127">

The value from #cinDays I want to be a parameter for a.cs C# method. This method is called inside an @if statement in my view

Answer 1

In the JavaScript function you can access the value like below:

function yourfunc() {
    let param = $("#cinDays").val();   
    // Now using the `param` value 
    ... 
}

Answer 2

As I understand cinDays is a part of view model so you can access to this property like this

...

<div>
      @if(someFunc(Model.cinDays)) {
       //some code
      }
</div>
