错误代码：

子组件：

<template>
 <div v-show="showMine">
  <div class="mask" @click.self="onMask"></div>
  <transition name="slide-fade">
   <div class="my_group" v-if="showMine">我的</div>
  </transition>
 </div>
</template>
 
<script>
export default {
 name: "mine",
 props: ["showMine"],
 data() {
  return {};
 },
 methods: {
  onMask() {
   this.$emit("onMask");
  }
 }
};
</script>
 
<style lang="less" scoped>
.mask {
 width: 100%;
 height: 100%;
 position: fixed;
 top: 0;
 left: 0;
 bottom: 0;
 right: 0;
 background-color: rgba(0, 0, 0, 0.1);
 z-index: 10;
}
.my_group {
 width: 60%;
 top: 0;
 bottom: 0;
 height: 100%;
 background-color: #fff;
 position: fixed;
 z-index: 11;
}
.slide-fade-enter-active,
.slide-fade-leave-active {
 transition: all 0.3s ease;
}
.slide-fade-enter,
.slide-fade-leave-to {
 transform: translateX(-100%);
 transition: all 0.3s ease;
}
</style>

父组件：

<template>
 <div class="headers">
  <div class="nav">
   <div class="mine" @click="onMine">
    <i class="cubeic-person"></i>
   </div>
   <div class="city">
    深圳市
    <i class="cubeic-pulldown"></i>
   </div>
   <div class="info">
    <i class="cubeic-message"></i>
   </div>
  </div>
  <app-mine :showMine="showMine" @onMask="onMask" />
 </div>
</template>
 
<script>
import appMine from "../Mine";
export default {
 name: "headers",
 components: {
  "app-mine": appMine
 },
 data() {
  return {
   showMine: false
  };
 },
 methods: {
  onMine() {
   this.showMine = true;
  },
  onMask() {
   this.showMine = false;
  }
 }
};
</script>
 
<style lang="less" scoped>
.nav {
 display: flex;
 justify-content: space-between;
 align-items: center;
 width: 100%;
 height: 1.066667rem;
 padding: 0 0.266667rem;
 box-sizing: border-box;
 font-size: 0.48rem;
 
 .city {
  font-size: 0.373333rem;
  color: #7e7e7e;
 }
}
.mine,
.info,
.city {
 height: 100%;
 line-height: 1.066667rem;
}
</style>
