鼠标移入移出，并没有出现闪动：
<template>
<div
class="alarmIcon"
ref="alarmIcon"
@mouseenter="handleEnter"
@mouseleave="handleLeave"
></div>
</template>
<script>
export default(){
mounted(){
},
methods:{
handleEnter(){
this.$refs['alarmIcon'].style.animation = 'blink 1s inifnite'
},
handleLeave(){
this.$refs['alarmIcon'].style.animation = 'noBlink 1s inifnite'
}
}
}
</script>
<style scoped>
.alarmIcon {
position: absolute;
top: 50%;
left: 50%;
width: 100px;
height: 100px;
border-radius: 50%;
transform: translate3d(-50%, -50%, 0);
background: #008c8c;
animation: noBlink 1s inifinite;
}
@keyframes blink {
0% {
opacity: 1;
}
100% {
opacity: 0;
}
}
@keyframes noBlink {
0% {
opacity: 1;
}
100% {
opacity: 1;
}
}
</style>样式中添加了 scoped，会导致.alarmIcon中的 animation 和 keyframe 中的动画会添加一个唯一标识，然后调用函数的时候 animation 是没有对应的标识的。
将 keyframes 下的内容放到 scoped 的外边或者去掉 scoped
