Image 图片

图片容器，在保留原生img的特性下，支持懒加载，自定义占位、加载失败等

基础用法

可通过fit确定图片如何适应到容器框，同原生 object-fit。

<div class="demo-image">
  <div class="block" v-for="fit in fits" :key="fit">
    <span class="demonstration">{{ fit }}</span>
    <el-image
      style="width: 100px; height: 100px"
      :src="url"
      :fit="fit"></el-image>
  </div>
</div>
<script>
  export default {
    data() {
      return {
        fits: ['fill', 'contain', 'cover', 'none', 'scale-down'],
        url: 'https://fuss10.elemecdn.com/e/5d/4a731a90594a4af544c0c25941171jpeg.jpeg'
      }
    }
  }
</script>

占位内容

可通过slot = placeholder可自定义占位内容

<div class="demo-image__placeholder">
  <div class="block">
    <span class="demonstration">默认</span>
    <el-image :src="src"></el-image>
  </div>
  <div class="block">
    <span class="demonstration">自定义</span>
    <el-image :src="src">
      <div slot="placeholder" class="image-slot">
        加载中<span class="dot">...</span>
      </div>
    </el-image>
  </div>
</div>
<script>
  export default {
    data() {
      return {
        src: 'https://cube.elemecdn.com/6/94/4d3ea53c084bad6931a56d5158a48jpeg.jpeg'
      }
    }
  }
</script>

加载失败

可通过slot = error可自定义加载失败内容

<div class="demo-image__error">
  <div class="block">
    <span class="demonstration">默认</span>
    <el-image></el-image>
  </div>
  <div class="block">
    <span class="demonstration">自定义</span>
    <el-image>
      <div slot="error" class="image-slot">
        <i class="el-icon-picture-outline"></i>
      </div>
    </el-image>
  </div>
</div>

懒加载

可通过lazy开启懒加载功能，当图片滚动到可视范围内才会加载。可通过scroll-container来设置滚动容器，若未定义，则为最近一个overflow值为auto或scroll的父元素。

<div class="demo-image__lazy">
  <el-image v-for="url in urls" :key="url" :src="url" lazy></el-image>
</div>

<script>
  export default {
    data() {
      return {
        urls: [
          'https://fuss10.elemecdn.com/a/3f/3302e58f9a181d2509f3dc0fa68b0jpeg.jpeg',
          'https://fuss10.elemecdn.com/1/34/19aa98b1fcb2781c4fba33d850549jpeg.jpeg',
          'https://fuss10.elemecdn.com/0/6f/e35ff375812e6b0020b6b4e8f9583jpeg.jpeg',
          'https://fuss10.elemecdn.com/9/bb/e27858e973f5d7d3904835f46abbdjpeg.jpeg',
          'https://fuss10.elemecdn.com/d/e6/c4d93a3805b3ce3f323f7974e6f78jpeg.jpeg',
          'https://fuss10.elemecdn.com/3/28/bbf893f792f03a54408b3b7a7ebf0jpeg.jpeg',
          'https://fuss10.elemecdn.com/2/11/6535bcfb26e4c79b48ddde44f4b6fjpeg.jpeg'
        ]
      }
    }
  }
</script>

可通过 previewSrcList 开启预览大图的功能。

<div class="demo-image__preview">
  <el-image 
    style="width: 100px; height: 100px"
    :src="url" 
    :preview-src-list="srcList">
