単一コンポネントの場合、transitionに含まれるだけ
<transition name="component-fade" mode="out-in">
<component v-bind:is="view"></component>
</transition>
<script>
new Vue({
el: '#transition-components-demo',
data: {
view: 'v-a'
},
components: {
'v-a': {
template: '<div>Component A</div>'
},
'v-b': {
template: '<div>Component B</div>'
}
}
})
</script>
<style>
.component-fade-enter-active, .component-fade-leave-active {
transition: opacity .3s ease;
}
.component-fade-enter, .component-fade-leave-to
/* .component-fade-leave-active for below version 2.1.8 */ {
opacity: 0;
}
</style>
複数コンポネントの場合、transition-groupを使って
<div id="list-demo" class="demo">
<button v-on:click="add">Add</button>
<button v-on:click="remove">Remove</button>
<transition-group name="list" tag="p">
<span v-for="item in items" v-bind:key="item" class="list-item">
{{ item }}
</span>
</transition-group>
</div>
new Vue({
el: '#list-demo',
data: {
items: [1,2,3,4,5,6,7,8,9],
nextNum: 10
},
methods: {
randomIndex: function () {
return Math.floor(Math.random() * this.items.length)
},
add: function () {
this.items.splice(this.randomIndex(), 0, this.nextNum++)
},
remove: function () {
this.items.splice(this.randomIndex(), 1)
},
}
})
.list-item {
display: inline-block;
margin-right: 10px;
}
.list-enter-active, .list-leave-active {
transition: all 1s;
}
.list-enter, .list-leave-to
/* .list-leave-active for below version 2.1.8 */ {
opacity: 0;
transform: translateY(30px);
}
