transition 过渡动画
如果要在vue中实现过渡动画，需要使用 transition 标签，名字可以随便取。

在Vue中使用Animate.css库
学前-代码案例
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>在vue中使用Animate.css库</title>
<script src="./vue.js"></script>
<style>
@keyframes bounce-in{
0%{
transform: scale(0);
}
50%{
transform: scale(1.5);
}
100%{
transform: scale(1);
}
}
.fade-enter-active{
transform-origin: left center;
animation: bounce-in 1s;
}
.fade-leave-active {
transform-origin: left center;
/* 动画反向运行 */
animation: bounce-in 1s reverse;
}
</style>
</head>
<body>
<div id="root">
<!-- 如果要实现过渡动画，需要使用 transition 标签，名字可以随便取,需要与css样式对应 -->
<transition name="fade">
<div v-if="show"> hello world </div>
</transition>
<button @click="handleClick">切换</button>
</div>
<script>
var vm = new Vue({
el: "#root",
data: {
show: true,
},
methods: {
handleClick: function () {
this.show = !this.show
}
}
})
</script>
</body>
</html>
在显隐过程中有放大缩小效果。
自定义动画名称
<!DOCTYPE html>

<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>在vue中使用Animate.css库</title>
<script src="./vue.js"></script>
<style>
@keyframes bounce-in {
0% {
transform: scale(0);
}
50% {
transform: scale(1.5);
}
100% {
transform: scale(1);
}
}
/* 自定义动画效果名称 */
.active {
transform-origin: left center;
animation: bounce-in 1s;
}
.leave {
transform-origin: left center;
/* 动画反向运行 */
animation: bounce-in 1s reverse;
}
</style>
</head>
<body>
<div id="root">
<!-- 如果要实现过渡动画，需要使用 transition 标签，名字可以随便取,需要与css样式对应 -->
<!-- 自定义动画名称需要声明 -->
<transition name="fade" enter-active-class="active" leave-active-class="leave">
<div v-if="show"> hello world </div>
</transition>
<button @click="handleClick">切换</button>
</div>
<script>
var vm = new Vue({
el: "#root",
data: {
show: true,
},
methods: {
handleClick: function () {
this.show = !this.show
}
}
})
</script>
</body>
</html>
Animate.css 官网

<script src="./vue.js"></script>
<!-- 引入css文件 -->
<link rel="stylesheet" href="./animate.css">
</head>
<body>
<div id="root">
<!-- 如果要实现过渡动画，需要使用 transition 标签，名字可以随便取,需要与css样式对应 -->
<!-- 自定义动画名称需要声明 -->
<transition name="fade" enter-active-class="animated swing" leave-active-class="animated shake">
<div v-if="show"> hello world </div>
</transition>
<button @click="handleClick">切换</button>
</div>
<script>
var vm = new Vue({
el: "#root",
data: {
show: true,
},
methods: {
handleClick: function () {
this.show = !this.show
}
}
})
</script>
</body>
</html>
进入退出都会添加动画效果！
animate 使用注意事项
- 要使用自定义形式使用 animate.css。
- class类里面必须包含一个 animated 具体的类，根据需求不同，把动画效果写在后面。
