Bootstrap Toggle Not working on disabled-enabled with limited elements

I am using Bootstrap Toggle Library with Bootstrap4 but I have problems when I try to control that user only switch 'ON' a limited number of elements. Here is my HTML code:

<div style="border:solid border-width: 1px;">
       <li class="ui-state-default">
           <input type="checkbox" name="checkImg" data-height="10" data-toggle="toggle" data-size="mini"data-onstyle="success" data-offstyle="danger">
                 Option 1
    </li> </div>

All 11 elements has the same code, and my Jquery:

$('input[name="checkImg"]').on('change', function (e) {
    if ($('input[name="checkImg"]:checked').length > 3 ) {
          console.log("In Condition");
          $(this).prop('checked', false);   
     }                        
   });

Here is a photo of the result when I switch 4 elements to 'ON': enter image description here

I can see that condition is right and detect when 3 elements are switch 'ON' but I cant disabled the rest of 'False' input until some of 'On' Elements switch to 'OFF'. Anyone can help?

In addition, I use disabled from bootstrap but not worked.

Thanks for all.

Solution

  • There is an error in your script. try to change this:

    $('input[name=checkImg]')

    to this

    $('input[name="checkImg"]')

    I tried correcting this and the script seems to work now.

    EDIT: I see the problem is with Bootstrap-toggle, that uses a different kind of approach for checking and unchecking checkboxes.

    Instead of just unchecking the checkbox you also have to change its parent div's class from "btn-success" to "btn-danger off". Now this code snippet should work for you as well.

    $('input[name="checkImg"]').on('change', function (e) {
    if ($('input[name="checkImg"]:checked').length > 3 ) {
        console.log("You can select no more than 3 options");
        $(this).prop('checked', false);
        $(this).parent().removeClass("btn-success");
        $(this).parent().addClass("btn-default off");
    }                        
});
