按钮转换使用 CSS 或 JS 来回切换

Question

我想创建一个按钮，单击它可以在两种状态之间来回切换。目前第一次点击成功将按钮转换为第二种状态，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：

$('.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>

Answer 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);
}

而不是这个你应该使用：

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

您现在可以切换它了。干杯！

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

<script src="http://code.jquery.com/jquery-1.10.2.min.js"></script>
<link href="//maxcdn.bootstrapcdn.com/font-awesome/4.1.0/css/font-awesome.min.css" rel="stylesheet">

<div>
  <button class="popup_contact" style="vertical-align:middle"><span><i class="fa fa-fighter-jet" aria-hidden="true"></i> </span>
  </button>
</div>

Answer 2

假设您希望按钮在单击之前保持静态（即悬停时也没有变化），您需要将 CSS 类更改为：

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

收件人：

.popup_contact.active {
  ...
}

.popup_contact.active:before {
  ...
}

目前，您的目标是各种伪状态，而您的 JavaScript 正在添加 class。

您需要 class .active 才能出现在您的 CSS 中，请参阅代码段

Answer 4

您的 CSS 没有 .active class.

尝试将此添加到您的 CSS:

.active {
border: 5px solid green;
}

激活时应添加绿色边框。
