<script src="https://cdn.bootcss.com/vue/2.4.2/vue.min.js"></script>

<style>
.box{
height:500px;
background-color:black;
overflow: hidden; }

//给过渡的name加样式

.mybox-leave-active,.mybox-enter-active{
transition: all 1s ease;
}
.mybox-leave-active,.mybox-enter{
height:0px !important;
}
.mybox-leave,.mybox-enter-active{
height: 500px;
}
</style>
</head><body>

<!-- 首先将要过渡的元素用transition包裹,并设置过渡的name) -->

<div id="box">
<transition name="mybox">
<div class="box" v-show="boxshow"></div>
</transition>
<button @click="togglebox">按钮</button>
</div>

<script>
new Vue({
el:'#box',
data:{
boxshow:false
},
methods:{

togglebox:function(){
this.boxshow = !this.boxshow;
}
}
});

</script>
</body>
</html>
