Vue自定义鼠标悬停图片，带预览和删除操作

公司这沙雕 UI 整天净整些没用的，非得逼我整些科技与狠活儿 …

就这破玩意儿能表现意思来就行了，非得鼠标悬停再显示操作按钮？

直接上效果图吧 …

定义 ComplexImage 组件

代码结构

StationChnqoodeMac-mini:complex-image net.cctv3.i$ tree
.
├── assets
│   ├── icon_delete.png
│   └── icon_preview.png
└── index.vue

实现

<!-- 鼠标悬浮，带删除和预览功能的Image组件 -->
<template>
  <div class="container">
    <el-image :src="source" :alt="source" :style="styles" />
    <div class="overlay">
      <div class="icons">
        <div class="icon" @click="onPreviewPress">
          <img class="image" src="./assets/icon_preview.png" />
        </div>
        <div style="width: 12px;" />
        <div class="icon" @click="onDeletePress">
          <img class="image" src="./assets/icon_delete.png" />
        </div>
      </div>
    </div>
  </div>
</template>

<script>
export default {
  name: 'complex-image',
  props: {
    source: {
      type: String,
      default: ''
    },
    styles: {
      type: String,
      default: ''
    }
  },

  data () {
    return {}
  },
  mounted () {},
  watch: {},
  methods: {
    onPreviewPress () {
      console.log('onPreviewPress ...')
    },
    onDeletePress () {
      console.log('onDeletePress ...')
    }
  }
}
</script>

<style>
.container {
  position: relative;
  display: inline-block;
}

.overlay {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  background-color: rgba(0, 0, 0, 0.5);
  color: white;
  text-align: center;
  line-height: 100px; /* 垂直居中 */
  opacity: 0;
  transition: opacity 1s;
  align-items: center;
  justify-content: center;
  display: flex;
  .icons {
    display: flex;
    .icon {
      .image {
        height: 16px;
        width: 16px;
      }
    }
  }
}

.container:hover .overlay {
  opacity: 1;
}
</style>

使用

<ComplexImage
  :styles="'height: 100px; width: 100px'"
  :source="'https://blog.cctv3.net/i.jpg'"
/>
