代码演示

基础用法

基础用法与原生img标签一致，可以设置src、width、height、alt等原生属性

<van-image
  width="100"
  height="100"
  src="https://img.yzcdn.cn/vant/cat.jpeg"
  rel="external nofollow" 
  rel="external nofollow" 
  rel="external nofollow"  
  rel="external nofollow"  
  rel="external nofollow" 
  rel="external nofollow" 
/>

填充模式

通过fit属性可以设置图片填充模式，可选值见下方表格

<van-image
  width="10rem"
  height="10rem"
  fit="contain"
  src="https://img.yzcdn.cn/vant/cat.jpeg" 
  rel="external nofollow"  
  rel="external nofollow" 
  rel="external nofollow" 
  rel="external nofollow" 
  rel="external nofollow"  
  rel="external nofollow" 
/>

圆形图片

通过round属性可以设置图片变圆，注意当图片宽高不相等且fit为contain或scale-down时，将无法填充一个完整的圆形。

<van-image
  round
  width="10rem"
  height="10rem"
  src="https://img.yzcdn.cn/vant/cat.jpeg"
  rel="external nofollow" 
  rel="external nofollow"  
  rel="external nofollow" 
  rel="external nofollow" 
  rel="external nofollow" 
  rel="external nofollow" 
/>

图片懒加载

设置lazy-load属性来开启图片懒加载，需要搭配 Lazyload 组件使用

<van-image
  width="100"
  height="100"
  lazy-load
  src="https://img.yzcdn.cn/vant/cat.jpeg"
  rel="external nofollow" 
  rel="external nofollow" 
  rel="external nofollow" 
  rel="external nofollow" 
  rel="external nofollow"
  rel="external nofollow" 
/>


import Vue from 'vue';
import { Lazyload } from 'vant';

Vue.use(Lazyload);

加载中提示

Image组件提供了默认的加载中提示，支持通过loading插槽自定义内容

<van-image src="https://img.yzcdn.cn/vant/cat.jpeg"
rel="external nofollow" 
rel="external nofollow"  
rel="external nofollow" 
rel="external nofollow"  
rel="external nofollow" 
rel="external nofollow" >
  <template v-slot:loading>
    <van-loading type="spinner" size="20" />
  </template>
</van-image>

加载失败提示

Image组件提供了默认的加载失败提示，支持通过error插槽自定义内容

<van-image src="https://img.yzcdn.cn/vant/cat.jpeg" 
rel="external nofollow"  rel="external nofollow"  
rel="external nofollow"  rel="external nofollow" 
rel="external nofollow"  rel="external nofollow" >
  <template v-slot:error>加载失败</template>
</van-image>
