vue3 el-upload单张图片回显、编辑、删除功能
图片回显时隐藏上传区域,鼠标悬浮显示遮罩层进行编辑、删除操作,删除图片后显示上传区域
vue部分:
①el-upload没有限制上传文件数量,如果limit=1,那么点击编辑时不会触发on-change事件,需要先清除当前文件,页面会出现上传区域;
②删除按钮click.stop阻止事件冒泡,删除后不会弹出上传图片窗口
<template> <el-upload class="upload-demo" drag action="#" accept=".jpg,.png" :on-change="handleChange" :auto-upload="false" ref="uploadRef" :show-file-list="false"> <!-- 图片上传框 --> <div v-if="!fileList.length"> <el-icon class="el-icon--upload"><upload-filled /></el-icon> <div class="el-upload__text"> Drop file here or <em>click to upload</em> </div> </div> <!-- 回显及遮罩层 --> <div v-else> <img :src="fileList[0].url" alt=""> <div class="mask"> <el-icon size="50"> <Edit /> </el-icon> <el-icon size="50" @click.stop="handleDelete"> <Delete /> </el-icon> </div> </div> <template #tip> <div class="el-upload__tip tip"> jpg/png files with a size less than 500kb </div> </template> </el-upload> </template>
ts部分:
<script setup lang="ts"> import { ref } from 'vue' import type { UploadFile, UploadUserFile } from 'element-plus' let fileList = ref<UploadUserFile[]>([]) const uploadRef = ref() const handleChange = (file: UploadFile) => { //如果上传的图片没有url字段,手动生成 if (!file.url) file.url = URL.createObjectURL(file.raw as any) fileList.value[0] = file } const handleDelete = () => { //删除时清除所有已上传图片 uploadRef.value.clearFiles() fileList.value = [] } </script>
样式:
<style lang="scss" scoped> :deep(.el-upload) { height: 100%; } :deep(.el-upload-dragger) { height: 100%; padding: 10px; display: flex; flex-direction: column; justify-content: center; align-items: center; box-sizing: border-box; } .upload-demo { width: 300px; height: 200px; } .tip { color: red; } //遮罩层 .mask { position: absolute; top: 0; left: 0; width: 100%; height: 100%; background: rgba(100, 100, 100, 0.5); color: #ffffff; opacity: 0; display: flex; justify-content: center; align-items: center; &:hover { opacity: 1; } .el-icon { margin: 0 10px; &:hover { color: #70aeed; } } } </style>
