Image

Besides the native features of img, support lazy load, custom placeholder and load failure, etc.

Basic Usage

:::demo Indicate how the image should be resized to fit its container by fit, same as native 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>
<!--
<setup>

  import { defineComponent, reactive, toRefs } from 'vue';

  export default defineComponent({
    setup() {
      const state = reactive({
        fits: ['fill', 'contain', 'cover', 'none', 'scale-down'],
        url: 'https://fuss10.elemecdn.com/e/5d/4a731a90594a4af544c0c25941171jpeg.jpeg'
      });

      return {
        ...toRefs(state),
      };
    },
  });
</setup>
-->

Placeholder

:::demo Custom placeholder content when image hasn't loaded yet by slot = placeholder

<div class="demo-image__placeholder">
  <div class="block">
    <span class="demonstration">Default</span>
    <el-image :src="src"></el-image>
  </div>
  <div class="block">
    <span class="demonstration">Custom</span>
    <el-image :src="src">
      <template #placeholder>
        <div class="image-slot">
          Loading<span class="dot">...</span>
        </div>
      </template>
    </el-image>
  </div>
</div>

<script>
  export default {
    data() {
      return {
        src: 'https://cube.elemecdn.com/6/94/4d3ea53c084bad6931a56d5158a48jpeg.jpeg'
      }
    }
  }
</script>
<!--
<setup>

  import { defineComponent, ref } from 'vue';

  export default defineComponent({
    setup() {
      const src = ref('https://cube.elemecdn.com/6/94/4d3ea53c084bad6931a56d5158a48jpeg.jpeg');

      return {
        src,
      };
    },
  });

</setup>

Load Failed

:::demo Custom failed content when error occurs to image load by slot = error

<div class="demo-image__error">
  <div class="block">
    <span class="demonstration">Default</span>
    <el-image></el-image>
  </div>
  <div class="block">
    <span class="demonstration">Custom</span>
    <el-image>
      <template #error>
        <div class="image-slot">
          <i class="el-icon-picture-outline"></i>
        </div>
      </template>
    </el-image>
  </div>
</div>

Lazy Load

:::demo Use lazy load by lazy = true. Image will load until scroll into view when set. You can indicate scroll container that adds scroll listener to by scroll-container. If undefined, will be the nearest parent container whose overflow property is auto or scroll.

<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: [
