Vue 中组件中传参数，传函数

1：接收值得一方

<template>
 <div style="font-size: 12px;line-height: 60px ;display: flex">
  <div style="flex: 1; font-size: 18px">
    <span :class="collapseBtnClass" style="cursor: pointer" @click="handleCollapse"></span>
  </div>
  <el-dropdown style="width: 100px; cursor: pointer">
    <span>王小虎</span><i class="el-icon-arrow-down" style="margin-left: 5px"></i>
    <el-dropdown-menu slot="dropdown">
      <el-dropdown-item>个人信息</el-dropdown-item>
      <el-dropdown-item>退出</el-dropdown-item>
    </el-dropdown-menu>
  </el-dropdown>
  </div>
</template>

<script>
export default {
  name: "Header",
  props:{
    collapseBtnClass:String,
    collapse:Function
  },
  methods: {
    handleCollapse() {
      if (typeof this.collapse === 'function') {
        this.collapse(); // 调用传递过来的函数
      }
    }
  }
}
</script>

<style scoped>

</style>

2：传值得一方

 <Aside :isCollapse="isCollapse" :logoTextShow="logoTextShow"></Aside>


 <Header :collapseBtnClass = "collapseBtnClass" :collapse="collapse"></Header>
