文章展示了如何在Vue项目中引入和使用VueHoverMask组件，该组件在鼠标悬停时显示一个覆盖层，并提供点击事件处理。通过定义默认插槽和action插槽，可以自定义内容和操作按钮，同时提供了详细的CSS样式来控制组件外观。

import VueHoverMask from 'vue-hover-mask'
export default {
  components: {
    VueHoverMask
  }
}

<template>
  <div id="app">
    <vue-hover-mask @click="handleClick">
      <!-- 默认插槽 -->
      <img src="https://cn.vuejs.org/images/logo.png" alt="" srcset="">
      <!-- action插槽 -->
      <template v-slot:action>
        <i class="iconfont icon-bianji-copy">编辑</i>
      </template>
    </vue-hover-mask>
  </div>
</template>

<script>
import VueHoverMask from './components/VueHoverMask'
export default {
  name: 'app',
  components:{ VueHoverMask },
  methods: {
    handleClick() {
      console.log('click')
    }
  }
}
</script>
<style>
@import url("//at.alicdn.com/t/font_1262845_52b6h42svd7.css");
.iconfont {
  font-size: 25px;
}
</style>

VueHoverMask/index.vue

<template>
  <div class="vue-hover-mask">
    <slot></slot>
    <span
      @click="handleClick"
      class="vue-hover-mask_action"
    >
      <slot name="action"></slot>
    </span>
  </div>
</template>

<script>
export default {
  name: 'VueHoverMask',
  methods: {
    handleClick () {
      this.$emit('click')
    }
  }
}
</script>

<style>
.vue-hover-mask {
  overflow: hidden;
  position: relative;
  line-height: 1;
  background-color: #fff;
  border-radius: 6px;
  box-sizing: border-box;
  display: inline-block;
  font-size: 0;
  vertical-align: middle;
}
.vue-hover-mask_action {
  position: absolute;
  width: 100%;
  height: 100%;
  left: 0;
  top: 0;
  cursor: pointer;
  text-align: center;
  color: #fff;
  opacity: 0;
  font-size: 20px;
  z-index: 1;
  background-color: rgba(0, 0, 0, 0.4);
  transition: opacity 0.3s;
}
.vue-hover-mask_action::after {
  display: inline-block;
  content: "";
  height: 100%;
  vertical-align: middle;
}
.vue-hover-mask_action:hover {
  opacity: 1;
}
</style>
