推广型网站建设模板网页字体网站

UI效果图：

 

实现思路：
循环图片数组，只展示几张宽度就为几张图片+边距的宽度，剩下的图片直接堆叠展示

点击预览的时候传入当前的下标，如果是点击堆叠的话，下标从堆叠数量开始计算
 

<template><!-- 查看图片展示 --><view class="image pos-re" :style="imageStyle"><u-image :width="width" :height="height" :src="formatImgUrl(item)" border-radius="8" :style="imgStyle" class="img" v-for="(item, index) in imagesList" @click="previewImage(0, index,item)"></u-image><view class="mask pos-ab" :style="maskStyle" v-if="imagesList.length > 4" @click="previewImage(1, 3)"><u-icon name="plus" size="28" color="#FFFFFF"></u-icon>{{imagesList.length+1  - imgNum }}</view></view>
</template><script>
export default {name:"showImage",props:{imagesList: {type: Array,default: () => {return []},},width: {type: [String, Number],default: 104,},height: {type: [String, Number],default: 104,},// 图片之间的右边距marginRight: {type: [String, Number],default: 10,},// 保留照片数imgNum: {type: [String, Number],default: 4,}},data() {return {baseFileUrl: process.uniEnv.BASE_FILEURL,imageStyle: {'width': '0rpx','overflow': 'hidden'},imgStyle: {'margin-right': '0rpx',},maskStyle: {width: '0rpx',height: '0rpx'},}},onLoad() {},watch: {imagesList:{handler(nV,oV){this.imgStyle.marginRight = this.marginRight + 'rpx';this.imageStyle.width = (this.width * this.imgNum ) + (this.marginRight * this.imgNum-1) + 'rpx';this.maskStyle.width = this.width + 'rpx';this.maskStyle.height = this.height + 'rpx';this.maskStyle.lineHeight = this.height + 'rpx';this.maskStyle.right = 0 + 'rpx';},immediate: true,deep: true}},methods: {formatImgUrl(img) {if (!img || img == '/static/images/image_noData.png') {return '/static/images/image_noData.png'}let imgs = img.split(',');return this.baseFileUrl + imgs[0]},previewImage(num, index, item) {let arr = [];if(this.imagesList.length){this.imagesList.forEach(item => {arr.push(this.baseFileUrl + item )})}if(!num) {uni.previewImage({current:index,urls: arr})}else{uni.previewImage({current: 3,urls: arr})}}}
