Image 圖片

圖片容器，在保留原生 img 的特性下，支持懶加載，自定義占位、加載失敗等

基礎(chǔ)用法

可通過(guò)fit確定圖片如何適應(yīng)到容器框，同原生 object-fit。

<template>
  <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>
</template>

<script>
  export default {
    data() {
      return {
        fits: ['fill', 'contain', 'cover', 'none', 'scale-down'],
        url: 'https://fuss10.elemecdn.com/e/5d/4a731a90594a4af544c0c25941171jpeg.jpeg',
      }
    },
  }
</script>

占位內(nèi)容

可通過(guò)slot = placeholder可自定義占位內(nèi)容

<template>
  <div class="demo-image__placeholder">
  <div class="block">
    <span class="demonstration">默認(rèn)</span>
    <el-image :src="src"></el-image>
  </div>
  <div class="block">
    <span class="demonstration">自定義</span>
    <el-image :src="src">
      <template #placeholder>
        <div class="image-slot">加載中<span class="dot">...</span></div>
      </template>
    </el-image>
  </div>
</div>
</template>

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

加載失敗

可通過(guò)slot = error可自定義加載失敗內(nèi)容

<template>
  <div class="demo-image__error">
  <div class="block">
    <span class="demonstration">默認(rèn)</span>
    <el-image></el-image>
  </div>
  <div class="block">
    <span class="demonstration">自定義</span>
    <el-image>
      <template #error>
        <div class="image-slot">
          <i class="el-icon-picture-outline"></i>
        </div>
      </template>
    </el-image>
  </div>
</div>
</template>

懶加載

可通過(guò)lazy開(kāi)啟懶加載功能，當(dāng)圖片滾動(dòng)到可視范圍內(nèi)才會(huì)加載?？赏ㄟ^(guò)scroll-container來(lái)設(shè)置滾動(dòng)容器，若未定義，則為最近一個(gè)overflow值為auto或scroll的父元素。

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

<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>

大圖預(yù)覽

可通過(guò) previewSrcList 開(kāi)啟預(yù)覽大圖的功能。

<template>
  <div class="demo-image__preview">
  <el-image
