Props

AttributeDescriptionTypeOptionsDefault

qrcodeProps*props of qrcode dependencyobject

qrcode

::: tip
如果将 qrcode 设为 'auto',pic-viewer 会自动判断是否需要转换(value 为 base64 或 url 时不会转换) :::

viewerjsProps

// 默认值

{
  zIndex: 5000,
}

qrcodeProps

// 默认值

{
  margin: 0,
  errorCorrectionLevel: 'L',
  width: 444,
  height: 444,
}

swiperProps

// 默认值

{
  observer: true,
}

Config rules

  • 所有参数均支持全局或局部配置

权重:

  • 局部配置高于全局配置
  • 对于对象类型的参数 局部配置会与全局配置进行合并 同名属性会被局部配置覆盖

Events

NameDescriptionCallback's arguments
click点击图片后触发{ src, index }

Slots

NameDescription
默认插槽自定义img标签
<!-- 示例 -->

<PicViewer>
  <template v-slot="{ src, index }">
    <img :src="src" alt="">
    <div>第{{ index + 1 }}张</div>
  </template>
</PicViewer>

Methods

MethodDescriptionParameters
previewpreview manuallyindex of value array (default: 0)

编程式调用预览

Preview manually, no external display


<PicViewer :value="" v-show="false" ref="PicViewer"/>
<button @click="()=>{$refs.PicViewer.preview(6)}">preview</button>

二维码清晰度

默认的图片css高度为148px(与 el-upload 保持一致),默认的二维码分辨率为444×444(三倍图),如果你增大了图片的css尺寸,将导致图片变模糊

解决:将二维码分辨率设置为展示尺寸的三倍

<!-- 示例 -->

<template>
  <PicViewer :qrcodeProps="{
    width: 900,
    height: 900 
  }"/>
</template>

<style scoped>
::v-deep .pic-viewer img {
  width: 300px;
  height: 300px;
}
</style>

获取 swiper 实例


<template>
  <PicViewer pattern="swiper" ref="picViewer" :swiperProps="{
    on: {
      init: onSwiperInit,
    },
  }"/>
</template>

<script>
import 'pic-viewer/dist/style.css'
import PicViewer from 'pic-viewer'

export default {
  components: { PicViewer },
  data () {
    return {
      swiper: null
    }
  },
  methods: {
    onSwiperInit () {
      this.$nextTick(() => {
        this.swiper = this.$refs.picViewer.swiper
      })
    }
  }
}
</script>
