如何在vuejs中使用javascript在过渡中使用三元运算符？

<template>
  <div>
    <transition name="fade">
      <div v-if="showElement" class="element">过渡效果</div>
    </transition>
    <button @click="toggleElement">切换元素</button>
  </div>
</template>

<script>
export default {
  data() {
    return {
      showElement: false
    };
  },
  methods: {
    toggleElement() {
      this.showElement = !this.showElement;
    }
  }
};
</script>

<style>
.fade-enter-active,
.fade-leave-active {
  transition: opacity 0.5s;
}
.fade-enter,
.fade-leave-to {
  opacity: 0;
}
.element {
  background-color: #f0f0f0;
  padding: 10px;
}
</style>
