问题:

I would like to create a button that toggles back and forth between two states on click. Currently the first click transitions the button successfully to the second state, but I cannot get the button to transition back to the original state on the second click.

Here is my code:

$('.popup_contact').on('click', function() {
  $(this).toggleClass('active');
});
.popup_contact {
  display: inline-block;
  min-height: 50px;
  height: auto !important;
  width: 100px;
  padding-top: 5px;
  text-align: center;
  font-size: 20px;
  font-weight: 800;
  background: #e8eaed;
  border: none;
  border-radius: 10px;
  color: #424e65 !important;
  -webkit-transform: perspective(0px) translateZ(0);
  transform: perspective(0px) translateZ(0);
  -webkit-transition-property: color;
  transition-property: color;
  -webkit-transition-duration: 0.3s;
  transition-duration: 0.3s;
}
.popup_contact:before {
  font-family: FontAwesome;
  content: '\f00d';
  color: #fff;
  padding-top: 15px;
  border-radius: 10px;
  position: absolute;
  text-align: center;
  z-index: 1;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background: #424e65;
  -webkit-transform: scaleX(0);
  transform: scaleX(0);
  -webkit-transform-origin: 0 50%;
  transform-origin: 0 50%;
  -webkit-transition-property: transform;
  transition-property: transform;
  -webkit-transition-duration: 0.3s;
  transition-duration: 0.3s;
  -webkit-transition-timing-function: ease-out;
  transition-timing-function: ease-out;
}
.popup_contact:hover,
.popup_contact:focus,
.popup_contact:active {
  color: #424e65 !important;
  cursor: pointer;
  border: none;
  background: #e8eaed;
  outline: 0 !important;
}
.popup_contact:focus:before,
.popup_contact:active:before {
  -webkit-transform: scaleX(1);
  transform: scaleX(1);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<link href="//maxcdn.bootstrapcdn.com/font-awesome/4.1.0/css/font-awesome.min.css" rel="stylesheet" />
<button class="popup_contact" style="vertical-align:middle"><span><i class="fa fa-fighter-jet" aria-hidden="true"></i> </span>
</button>

This is because focus and active event is applied:

.popup_contact:focus:before,
.popup_contact:active:before {
  -webkit-transform: scaleX(1);
  transform: scaleX(1);
}

Instead of this you should use:

.popup_contact.active:before {
  -webkit-transform: scaleX(1);
  transform: scaleX(1);
}

and you can now toggle it. Cheers!

  </button>
</div>



回答2:

Assuming you want your button to be static until clicked (i.e. no change on hover also), you need to change your CSS clases from:

.popup_contact:hover,
.popup_contact:focus,
.popup_contact:active {
  ...
}
.popup_contact:focus:before,
.popup_contact:active:before {
  ...
}

To:

.popup_contact.active {
  ...
}

.popup_contact.active:before {
  ...
}

Currently, you're targeting the various psuedo states, whereas your JavaScript is adding a class.



回答3:

Your CSS doesnt have the .active class.

Try add this to your CSS:

.active {
border: 5px solid green;
}

This should add a green border when active.

You need the class .active to be in your CSS, see Snippet
