demo展示
用法

使用,SPA,非SSR
import Vue from 'vue'
import { showImages } from '../img-viewr'
import 'vue-img-viewr/styles/index.css'
Vue.prototype.$showImages = showImages
this.$showImages({
urls: this.urls,
index
})
import ImgViewr, { showImages } from 'vue-img-viewr'
import 'vue-img-viewr/styles/index.css'
export default {
components: { ImgViewr },
data () {
return {
urls: [

],
index: 0,
visible: false
}
},
methods: {
showImagesByComponent (index) {
this.visible = true
this.index = index
},
showImagesByJs (index) {
showImages({
urls: this.urls,
index
})
}
}
}
服务端渲染(SSR)中使用,以Nuxtjs为例
import Vue from 'vue'
import ImgViewr, { showImages } from 'vue-img-viewr'
import 'vue-img-viewr/styles/index.css'
export default () => {
Vue.prototype.$showImages = showImages
Vue.component(ImgViewr.name, ImgViewr)
}
plugins: [
{ src: '@/plugins/vue-img-viewr', ssr: false }
]
export default {
data () {
return {
urls: [
'https://s.gravatar.com/avatar/221f86a573320174bad7a62886a6d4b4?size=100&default=retro',
'https://s.gravatar.com/avatar/221f86a573320174bad7a62886a6d4b4',
'https://static.npmjs.com/attachments/ck3uwf5d872zb8874c3ayi1pj-icon-pro-wombat-3x.png'
],
index: 0,
visible: false
}
},
methods: {
showImagesByComponent (index) {
this.visible = true
this.index = index
},
showImagesByJs (index) {
this.$showImages({
urls: this.urls,
index
})
}
}
}
示例组件使用
<div class="demo">
<h3>通过组件方式</h3>
<div class="imgs">
<div v-for="(url, i) in urls" class="img" :key="`c_${i}`" @click="() => showImagesByComponent(i)">
<img :src="url" />
</div>
</div>
<ImgViewr :visible="visible" :urls="urls" :initialIndex="index" :onClose="() => (visible = false)" />
<h3>通过js方法调用</h3>
<div class="imgs">
<div v-for="(url, i) in urls" class="img" :key="`j_${i}`" @click="() => showImagesByJs(i)">
<img :src="url" />
</div>
</div>
</div>
示例样式
.imgs {
display: flex;
}
.img {
width: 150px;
height: 100px;
