本文实例为大家分享了vue动画封装的具体代码，供大家参考，具体内容如下
<style>
.v-enter,.v-leave-to{
opacity: 0;
}
.v-enter-active,.v-leave-active{
transition:opacity 1s;
}
</style>
<div id='app'>
<transition>
<div v-if='show'>hello world</div>
</transition>
<button @click='handleClick'>切换</button>
</div>
<script>
var vm = new Vue({
el:'#app',
data:{
show:true
},
methods:{
handleClick:function(){
this.show = !this.show;
}
}
})
</script>
有时候这种渐隐渐现的效果用的比较多，要复用，需要封装一下，怎么封装呢
<style>
.v-enter,.v-leave-to{
opacity: 0;
}
.v-enter-active,.v-leave-active{
transition:opacity 1s;
}
</style>
<div id='app'>
<fade :show='show'>
<div>hello world</div>
</fade>
<fade :show='show'>
<h1>hello world</h1>
</fade>
<button @click='handleClick'>切换</button>
</div>
<script>
Vue.component('fade',{
props:['show'],
template: `
<transition>
<slot v-if='show'></slot>
</transition>
`
})
var vm = new Vue({
el:'#app',
data:{
show:false
},
methods:{
handleClick:function(){
this.show = !this.show;
}
}
})
</script>
可以这样封装，将dom元素传入slot，除了这样，还可以样式一起封装进去
<div id='app'>
<fade :show='show'>
<div>hello world</div>
</fade>
<fade :show='show'>
<h1>hello world</h1>
</fade>
<button @click='handleClick'>切换</button>
</div>
<script>
Vue.component('fade',{
props:['show'],
template: `
<transition @before-enter='handleBeforeEnter' @enter='handleEnter'>
<slot v-if='show'></slot>
</transition>
`,
methods:{
handleBeforeEnter:function(el){
el.style.color='red'
},
handleEnter:function(el,done){
setTimeout(()=>{
el.style.color='green';
done();
},2000)
}
}
})
var vm = new Vue({
el:'#app',
data:{
show:false
},
methods:{
handleClick:function(){
this.show = !this.show;
}
}
})
</script>
把样式一起封装进来，是比较推荐的方式。
