使用,SPA,非SSR

/**
 * 一、推荐🔥全局js方式引入
 */
import Vue from 'vue'
import { showImages } from '../img-viewr'
import 'vue-img-viewr/styles/index.css'

Vue.prototype.$showImages = showImages

/** 使用 **/
this.$showImages({
  urls: this.urls,
  index
})

/**
 * 二、按需引入使用
 */
import ImgViewr, { showImages } from 'vue-img-viewr'
import 'vue-img-viewr/styles/index.css'

export default {
  // 注册组件
  components: { ImgViewr },
  data () {
    return {
      urls: [
        'https://s.gravatar.com/avatar/221f86a573320174bad7a62886a6d4b4?size=100&default=retro',
        'https://s.gravatar.com/avatar/221f86a573320174bad7a62886a6d4b4',
        'https://static.npmjs.com/attachments/ck3uwf5d872zb8874c3ayi1pj-icon-pro-wombat-3x.png'
      ],
      index: 0,
      visible: false
    }
  },
  methods: {
    // 通过组件方式
    showImagesByComponent (index) {
      this.visible = true
      this.index = index
    },
    showImagesByJs (index) {
      // 通过js方式显示
      showImages({
        urls: this.urls,
        index
      })
    }
  }
}

服务端渲染(SSR)中使用,以Nuxtjs为例

/**
 * 引用
 */
// @/plugins/vue-img-viewr.js
import Vue from 'vue'
import ImgViewr, { showImages } from 'vue-img-viewr'
import 'vue-img-viewr/styles/index.css'

export default () => {
  // 全局方法
  Vue.prototype.$showImages = showImages
  // 注册组件
  Vue.component(ImgViewr.name, ImgViewr)
}

// nuxt.config.js
plugins: [
  { src: '@/plugins/vue-img-viewr', ssr: false }
]

/**
 * 使用
 */
export default {
  data () {
    return {
      urls: [
        'https://s.gravatar.com/avatar/221f86a573320174bad7a62886a6d4b4?size=100&default=retro',
        'https://s.gravatar.com/avatar/221f86a573320174bad7a62886a6d4b4',
        'https://static.npmjs.com/attachments/ck3uwf5d872zb8874c3ayi1pj-icon-pro-wombat-3x.png'
      ],
      index: 0,
      visible: false
    }
  },
  methods: {
    // 通过组件方式
    showImagesByComponent (index) {
      this.visible = true
      this.index = index
    },
    showImagesByJs (index) {
      // 通过js方式显示
      this.$showImages({
        urls: this.urls,
        index
      })
    }
  }
}
