pic-viewer / 图片画廊

before preview

previewing


特性

  • viewerjs 的 Vue 版本,增加了预览前的外部展示,使其开箱即用
  • 多样的展示形式:支持文档流、轮播图、自适应瀑布流、嵌套在表格内
  • 灵活的数据类型:支持字符串、字符串数组、JSON字符串、对象数组
  • 图片源支持URL、Base64、二维码
  • 全局或局部引入,参数支持全局或局部配置

安装

NPM

npm add pic-viewer viewerjs
// 全局引入

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

Vue.use(PicViewer, {
  // 全局配置
})
<!-- 局部引入 -->

<template>
  <PicViewer v-bind="{/* 局部配置 */}"/>
</template>

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

export default {
  components: { PicViewer },
}
</script>

参数

参数名说明类型可接受值默认值
value图片源string, string[], object[]
pattern展示模式stringwaterfall, swiper, table-cellundefined(即文档流)
viewerjs是否启用 viewerjsbooleantrue
viewerjsPropsviewerjs 的参数object{ zIndex: 5000, zoomRatio: 0.4 }
srcAt指定图片源所在的键(如果 value 为对象(数组)类型)string
swiperPropsswiper 的参数object{ observer: true }
qrcode是否将 value 转换为二维码boolean, stringtrue, false, autofalse
qrcodePropsqrcode 的参数object{ margin: 0, errorCorrectionLevel: 'L', width: 444, height: 444 }

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) :::


配置规则

  • 双向绑定参数(v-model / modelValue)仅支持局部配置
  • 其余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

事件

名称说明参数
click点击图片后触发{ src, index }

插槽

名称说明
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>

方法

名称说明参数
preview手动预览数组下标,默认值为 0

编程式调用预览

手动调用预览,不再外部展示


<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>
