How to transform boolean input values to string values using C# (MVC)?

Question

I’m having trouble transforming values from a Toggle input into a string value to be stored in a BD. The goal is to make a Buy/Sell Toggle that shows the type of operation the user is entering the information, returning, in string, a "C" or "V" depending on the option:

But I’m not getting the value of Toggle!

This is the code I’m doing to take what the button comes out and turn it into the strings

<script>
$(document).ready(function () {
        if ($("Tipo_ope").val().toLowerCase() === 'true')
            return "C"
        else
            return "V"
    }
 );
 </script>

I also tried for the Controller, but I can’t get the result by the parameter, and it didn’t work either... I am still beginner in this MVC method and still do not understand some things, so I ask if there is someone who knows how to solve this?

Answer 1

You should not treat this in your frontend, the user can handle this function. Send in your form to the controller the value of the field:

$("Tipo_ope").val();

Obs: this selector may be wrong, remember to use the prefix "#" to select by ID: $("#Tipo_ope").val();

When your controller/service has the boolean value of this property, when instantiating the object before saving it in the database you can make a negotiation:

var objeto = new objeto() 
{
    tipoOperacao = tipoOpe ? "V" : "C",
};

Obs2: Wouldn’t it be more viewable to use the boolean in your database and instead of storing a char or a string, a flag, for example "Isvenda"?
