要在class的样式中加上transform-origin: left center，不然可能会出问题：
<!DOCTYPE html> <html> <head> <title></title> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <script src="./vue.js"></script> <!-- <script src="http://cdn.staticfile.org/vue/2.6.10/vue.common.dev.js"></script> --> <style type="text/css"> @keyframes bounce-in { 0% { transform: scale(0); } 50% { transform: scale(15); } 100% { transform: scale(1); } } .fade-enter-active { transform-origin: left center; animation: bounce-in 1s; } .fade-leave-active { transform-origin: left center; animation: bounce-in 1s reverse; } </style> </head> <body> <div id="root"> //name随便取名: <transition name="fade"> <div v-show="show">hello</div> </transition> <button @click="handleClick">切换</button> </div> <script type="text/javascript"> var vm = new Vue({ el: "#root", data: { show: true }, methods: { handleClick: function() { this.show = !this.show } } }); </script> </body> </html>
当然，还可以自定义style中的class名：
<!DOCTYPE html>
<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<script src="./vue.js"></script>
<!-- <script src="http://cdn.staticfile.org/vue/2.6.10/vue.common.dev.js"></script> -->
<style type="text/css">
@keyframes bounce-in {
0% {
transform: scale(0);
}
50% {
transform: scale(15);
}
100% {
transform: scale(1);
}
}
/*.fade-enter-active {
transform-origin: left center;
animation: bounce-in 1s;
}
.fade-leave-active {
transform-origin: left center;
animation: bounce-in 1s reverse;
}*/
.haha-active {
transform-origin: left center;
animation: bounce-in 1s;
}
.haha-leave {
transform-origin: left center;
animation: bounce-in 1s reverse;
}
</style>
</head>
<body>
<div id="root">
//name随便取名:
<!-- <transition name="fade">
<div v-show="show">hello</div>
</transition> -->
//自定义class名字：
<transition name="fade" enter-active-class="haha-active" leave-active-class="haha-leave">
<div v-show="show">hello</div>
</transition>
<button @click="handleClick">切换</button>
</div>
<script type="text/javascript">
var vm = new Vue({
el: "#root",
data: {
show: true
},
methods: {
handleClick: function() {
this.show = !this.show
}
}
});
</script>
</body>
</html>自己命名class名有个好处，可以用别人的动画。css在这个网址下载：https://daneden.github.io/animate.css/
