Vue3后台管理系统Hamburger组件

在Vue 3中创建一个名为Hamburger.vue的组件，用于实现一个用于切换侧边栏显示状态的按钮。

<template>
  <div class="hamburger" :class="{ 'is-active': isActive }" @click="toggle">
    <div class="hamburger-box">
      <div class="hamburger-inner"></div>
    </div>
  </div>
</template>
 
<script>
export default {
  name: 'Hamburger',
  props: {
    isActive: {
      type: Boolean,
      required: true
    }
  },
  methods: {
    toggle() {
      this.$emit('toggle');
    }
  }
};
</script>
 
<style scoped>
.hamburger {
  cursor: pointer;
  transition-property: opacity, filter;
  transition-duration: 300ms;
  transition-timing-function: linear;
  font: inherit;
  color: inherit;
  background-color: transparent;
  margin: 0;
  padding: 0;
  display: inline-block;
  overflow: visible;
}
 
.hamburger-box {
  display: inline-block;
  position: relative;
  font-size: 24px;
  width: 40px;
  height: 40px;
  transition: transform 0.3s ease;
}
 
.hamburger-inner {
  display: block;
  top: 50%;
  width: 40px;
  height: 2px;
  margin-top: -1px;
  background-color: #000;
  transition: transform 0.3s ease;
}
 
.hamburger.is-active .hamburger-inner {
  transform: translate3d(0, -50%, 0) rotate(90deg);
  transition-delay: 150ms;
}
</style>

这个Hamburger.vue组件包含一个hamburger图标，当它被点击时，会发出一个toggle事件，可以被父组件监听并作出响应（比如切换侧边栏的显示状态）。.is-active 类用于改变hamburger图标的样式，表示侧边栏当前是展开还是折叠状态。
