我想创建一个按钮，在点击时在两种状态之间来回切换。目前第一次点击将按钮成功转换到第二个状态，但我无法让按钮在第二次点击时转换回原始状态。

这是我的代码：

＆＃13;
＆＃13; 
$('.popup_contact').on('click', function() {
  $(this).toggleClass('active');
});
＆＃13; 
.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);
}

这是因为应用了focus和active事件：

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

而不是这样你应该使用：

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

现在可以切换它。干杯！

假设您希望按钮在被点击之前是静态的（即悬停时也没有变化），您需要更改CSS clases：

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

要：

.popup_contact.active {
  ...
}

.popup_contact.active:before {
  ...
}

目前，您的目标是各种伪的状态，而您的JavaScript正在添加一个类。

你的CSS没有.active类。

尝试将此添加到您的CSS：

.active {
border: 5px solid green;
}

这应该在激活时添加绿色边框。
