Vue开发时，经常会遇到写切换，每次都要手写一般很累人，存个备份留待后期复用。

<template>
  <div class="tabs">
    <div class="tab cur" :class="{active:active==index}" @click="getactive(index)" v-for="(item,index) in list"
         :key="index"><span>{{ item }}</span>
    </div>
  </div>
</template>

<script>

export default {
  name: "tabs",
  components: {},
  props: {
    id: {
      type: String,
      default() {
        return '';
      }
    }
  },
  data() {
    return {
      list: ['今天', '7日', '30日'],
      active: 0
    }
  },
  watch: {},
  mounted() {
  },
  methods: {
    getactive(e) {
      this.active = e
      this.$emit('getactive', e)
    }
  }
}
</script>
