in Vue with Vuetify, I want to change dynamically v-cards with animate.css
, and I'm facing a problem. The out-in
mode doesn't want to work in this situation. Fade-in and fade-out animations are moving at the same time. How can force it to start the fade-in animation after ending a fade-in?
new Vue({
el: '#app',
data() {
return {
number: 1,
items: [
{
text: "a",
number: 1
},
{
text: "b",
number: 2
},
{
text: "c",
number: 3
},
]
}
}
})

<div id="app">
<div v-for="(item, index) in items" :key="index">
<transition mode="out-in" enter-active-class="animated slideInLeft" leave-active-class="animated slideOutRight">
<v-card dark class="ma-3" v-if="number === item.number">
<p>{{item.text}}</p>
</v-card>
</transition>
</div>
<br>
<v-btn @click="number++; if(number === 4) number = 1;">Next</v-btn>
</div>
Your transition is inside a loop which means after the rendering you will have multiple transitions
that have no relation to each other (mode
doesn't work)... this is how your template will look like after rendering :
<div key="0">
<transition mode="out-in" enter-active-class="animated slideInLeft" leave-active-class="animated slideOutRight">
<v-card dark class="ma-3" v-if="true">
<p>a</p>
</v-card>
</transition>
</div>
<div key="1">
<transition mode="out-in" enter-active-class="animated slideInLeft" leave-active-class="animated slideOutRight">
<!-- <v-card dark class="ma-3" v-if="false">
<p>b</p>
</v-card> -->
</transition>
</div>
<div key="2">
<transition mode="out-in" enter-active-class="animated slideInLeft" leave-active-class="animated slideOutRight">
<!-- <v-card dark class="ma-3" v-if="false">
<p>c</p>
</v-card> -->
</transition>
</div>
<div key="3">
<transition mode="out-in" enter-active-class="animated slideInLeft" leave-active-class="animated slideOutRight">
<!-- <v-card dark class="ma-3" v-if="false">
<p>d</p>
</v-card> -->
</transition>
</div>
so when you press next you are jumping from a transition to another one ...and in this case the mode
is lost .
we just need to wrap our whole items inside a transition, so in this case there is only one transition
that will detect when an element is going out and a new one is coming in (mode
will work) :
Vue.config.devtools = false;
Vue.config.productionTip = false;
new Vue({
el: '#app',
data() {
return {
number: 1,
items: [{
text: "a",
number: 1
},
{
text: "b",
number: 2
},
{
text: "c",
number: 3
},
]
}
}
})
