<div
      v-for="(route, idx) in route"
      @click="handleChangeRoute(route, idx)">
      {{ route.meta.context }}
      <div 
        class="arrow-fr" 
        v-if="route.children && route.children.length > 0">
        <img v-if="openNavIndex === idx" src="@/assets/arrow-up.jpg">
        <img v-if="openNavIndex !== idx" src="@/assets/arrow-down.jpg">
      </div>
      <div 
        class="route-child" 
        v-if="openNavIndex === idx">
        <div 
          @click="handleChangeSubRoute(childItem)"
          v-for="(childItem, childIndex) in route.children" 
          :key="childIndex">
          {{ childItem.meta.context }}
        </div>
      </div>
    </div>

data() {
    return {
      openNavIndex: null,
    }
  },

handleChangeRoute (route, idx) {
      if (route.children) {
        if (this.openNavIndex === idx) {
          this.openNavIndex = null
        } else {
          this.openNavIndex = idx
        }
      }
      if (!route.children)
        this.openNavIndex = null
    }

數據

當我按下 handleChangeRoute 時
把 index 給 openNavIndex 讓 subnav 開啟～
但是我按下 handleChangeSubRoute 時，我並不想讓它觸動 handleChangeRoute （因為我不想將 index 給 openNavIndex）
請問怎麼寫才對？
