How can I change button color when clicked

To be brief, i have two buttons that have the same class, one of them have an attribute data-toggle='modal'. I use this attribute to detect the button.

I need to change the color of the button which does not have an attribute data-toggle, I can't target it by using the className, because they both have the same.

In the js click function, I use a ternary condition to say: if the button has an attribute 'data-toggle' then do nothing, else removeClass btn--ghost and addClass btn--plain. But it doesn't work.

PS: the btn--plain is the class name used to give the button a bgcolor instead of btn--ghost.

This is the js :

if ($('.o-block-global .btn--link').length) {
    $('.btn--primary').on("click", function (e) {
        console.log("iiiiii", $(this));
        $(this).attr("data-toggle" ? "" : $(this).removeClass("btn--ghost").addClass("btn--plain"));
    });
}

This is the HTML :

<div class="o-block-global__links link_choice "> 
    <button type="button" class="btn btn--ghost btn--primary">
        OUI   
    </button>

    <button type="button" class="btn btn--ghost btn--primary" data-toggle="modal" data-target="#modalChoice2"> 
        NON    
    </button>
 </div>

You can check if the attr value is undefined or not using (typeof $(this).attr("data-toggle")) !== 'undefined'

Demo Code :

$('.btn--primary').on("click", function(e) {
  //check if the attr type is not undefined
  (typeof $(this).attr("data-toggle")) !== 'undefined' ? "" : $(this).removeClass("btn--ghost").addClass("btn--plain");
});
.btn--ghost {
  color: red;
}

.btn--plain {
  color: blue
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.0/jquery.min.js"></script>
<div class="o-block-global__links link_choice ">
  <button type="button" class="btn btn--ghost btn--primary">
        OUI   
  </button>

  <button type="button" class="btn btn--ghost btn--primary" data-toggle="modal" data-target="#modalChoice2"> 
    NON    
  </button>

To do that you use the :active selector. HTML:

<button>Click Me!</button>   


button{
    background:green;
}
button:hover{
    background:lightgreen;
}
button:active{
    background:red;
}
