vue 토글을 사용하면 클릭하여 클래스를 전환할 수 있습니다(예제 설명)

<template>
  <p>
    <span :class="{&#39;bg-primary text-danger&#39;:isA,&#39;bg-success text-white&#39;:!isA}" @click="toggle()">AAAAA</span>
  </p>
</template>
<script>
  export default {
    name: &#39;hello&#39;,
    data () {
      return {
        isA: false
      }
    },
    methods:{
      toggle:function () {
        this.isA=!this.isA
      }
    }
  }
</script>
<style scoped>
  @import "../../../src/assets/plugin/bootstrap-4.0.0-alpha.6-dist/css/bootstrap.css";
</style>
