Disable button if all checkboxes are unchecked and enable it if at least one is checked

Question

I have a table with a checkbox in each row and a button below it. I want to disable the button if at least one checkbox is checked.

Answer 1

Try this one:

let $cbs = $(".myCheckBox").change(function() {
    if ($cbs.is(":checked")){
        // disable #confirmButton if at least one checkboxes were checked
        $("#confirmButton").prop("disabled", false);
    } else {
        // disable #confirmButton if all checkboxes were unchecked
        $("#confirmButton").prop("disabled", true);
    }
});
