jQuery在单击功能上添加和删除类的问题

Question

I have created a Jquery toggle class function which adds and removes the class flipped on a click eventListner. click here . At the moment this function is working when the user clicks on any of the elements wrapped in the .card class. I when want to restrict where the user can click, therefore only allow the click function to work when the user clicks the .active-btn .

I have made attempts to do this however once the card is flipped the active-btn class doesn't seem to work. by the looks of things the 'front div' is sitting on top of the 'back div Below is a snippet of my code …

$('.active-btn').click(function(e){
             e.preventDefault();
            $card = $(this).closest('.card');
            $('.flipped').not($card).removeClass('flipped');
            $card.toggleClass('flipped');
        });

Answer 1

I basically change the z-index to -1 on .flip .card .face , and

.flip .card {
  -webkit-transform-style: flat;
}

The problem with your original is that the perserved-3d keep changing the z-index which causing issues with the order.

z-index is canceled by setting transform(rotate)

Here is the post which goes in more detail.

You need to use the toggle element, right now the active btn will remove the class and won't add it after.

Do it like this:

$( ".active-btn" ).toggle(function() {
    e.preventDefault();
            $card = $(this).closest('.card');
            $('.flipped').not($card).removeClass('flipped');
            $card.toggleClass('flipped');
}, function() {
    e.preventDefault();
            $card = $(this).closest('.card');
            $('.flipped').not($card).addClass('flipped');
            $card.toggleClass('flipped'); );
});

Answer 3

use !hasClass (class has not exist) rather than not,

$('.active-btn').click(function(e){
         e.preventDefault();
        $card = $(this).closest('.card');
       if (!$('.flipped').hasClass($card)) {
                 removeClass('flipped');
                 $card.toggleClass('flipped');
            }
    });
