在Vue中使用Animate.css库

我们先来实现一个点击后能够放大和缩小的动画

<!DOCTYPE html>
<html lang="en">
<head>
	<meta charset="UTF-8">
	<title>Hello World</title>
	<script src="vue.js" type="text/javascript" charset="utf-8"></script>
	<link rel="stylesheet" type="text/css" href="animate.css">
	<script src="jquery-3.3.1.min.js" type="text/javascript" charset="utf-8"></script>
	<style type="text/css">
		@keyframes bounce-in{
			0% {
				transform: scale(0);
			}
			50% {
				transform: scale(1.5);
			}
			100% {
				transform: scale(1);
			}
		}
		.v-enter-active{
			transform-origin: left center;
			animation: bounce-in 1s;
		}
		.v-leave-active{
			transform-origin: left center;
			animation: bounce-in 1s reverse;
		}
	</style>
</head>
<body>
	<div id="vm">
		<transition>
			<div v-if="show">Hello World</div>
		</transition>
		<button @click="handleClick" type="button">change</button>
	</div>
	<script>
		var vm = new Vue({
			el: '#vm',
			data: {
				show: true
			},
			methods: {
				handleClick: function() {
					this.show = !this.show;
				}
			}
		});
	</script>
</body>
</html>

发现这样写还是有点麻烦的，我们可以直接使用animate库里的动画效果

首先去https://daneden.github.io/animate.css/网址，点击download animate下载下来，然后导入

enter里面的XXX表示你想要的进入特效

leave里面的XXX表示你想要的出去特效

想要什么样的特效都可以从这里面去选择

<!DOCTYPE html>
<html lang="en">
<head>
	<meta charset="UTF-8">
	<title>Hello World</title>
	<script src="vue.js" type="text/javascript" charset="utf-8"></script>
	<link rel="stylesheet" type="text/css" href="animate.css">
	<script src="jquery-3.3.1.min.js" type="text/javascript" charset="utf-8"></script>
</head>
<body>
	<div id="vm">
		<transition
			enter-active-class="animated flash"
			leave-active-class="animated bounceIn">
			<div v-if="show">Hello World</div>
		</transition>
		<button @click="handleClick" type="button">change</button>
	</div>
	<script>
		var vm = new Vue({
			el: '#vm',
			data: {
				show: true
			},
			methods: {
				handleClick: function() {
					this.show = !this.show;
				}
			}
		});
	</script>
</body>
</html>
