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

Image 图片 - 图1

可通过fit确定图片如何适应到容器框,同原生 object-fit

  1. <divclass="demo-image">
  2. <divclass="block"v-for="fit in fits" :key="fit">
  3. <spanclass="demonstration">{{ fit }}</span>
  4. <el-image
  5. style="width:100px; height:100px"
  6. :src="url"
  7. :fit="fit"></el-image>
  8. </div>
  9. </div>
  10. <script>
  11. exportdefault{
  12. data(){
  13. return{
  14. fits:['fill','contain','cover','none','scale-down'],
  15. url:'https://fuss10.elemecdn.com/e/5d/4a731a90594a4af544c0c25941171jpeg.jpeg'
  16. }
  17. }
  18. }
  19. </script>

占位内容

Image 图片 - 图2

可通过slot = placeholder可自定义占位内容

  1. <divclass="demo-image__placeholder">
  2. <divclass="block">
  3. <spanclass="demonstration">默认</span>
  4. <el-image :src="src"></el-image>
  5. </div>
  6. <divclass="block">
  7. <spanclass="demonstration">自定义</span>
  8. <el-image :src="src">
  9. <divslot="placeholder"class="image-slot">
  10. 加载中<spanclass="dot">...</span>
  11. </div>
  12. </el-image>
  13. </div>
  14. </div>
  15. <script>
  16. exportdefault{
  17. data(){
  18. return{
  19. src:'https://cube.elemecdn.com/6/94/4d3ea53c084bad6931a56d5158a48jpeg.jpeg'
  20. }
  21. }
  22. }
  23. </script>

加载失败

Image 图片 - 图3

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

Image 图片 - 图4

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autoscroll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>
