ui框架-文件列表展示

介绍

UI框架的文件列表展示组件，可以展示文件夹，支持列表展示和图标展示模式。组件提供了丰富的功能和可配置选项，适用于文件管理、文件上传等场景。

功能特性

支持列表模式和网格模式的切换展示
支持文件和文件夹的层级展示
支持文件选择和文件夹选择
支持拖拽上传文件
支持多选/单选模式
支持文件类型过滤
支持文件大小限制
支持图片文件预览

显示文件大小和最后修改时间

安装

npm install bbyh-ui-file-list-diaplay

使用示例

<template><FileListDisplaydefaultViewMode="grid":defaultFiles="files":acceptedTypes="['jpg', 'png', 'pdf']":maxFileSize="50":multiple="true":showFileSize="true":enableDrop="true"@select="handleSelect"@file-error="handleError"/>
</template><script setup>
import FileListDisplay from "bbyh-ui-file-list-diaplay";
import { ref } from 'vue';const files = ref([]);const handleSelect = (selectedFiles) => {console.log('Selected files:', selectedFiles);
};const handleError = (error) => {console.error('File error:', error);
};
</script>

Props 配置

属性名	类型	默认值	说明
defaultViewMode	String	‘list’	默认视图模式，可选值：‘list’/‘grid’
defaultFiles	Array	[]	默认显示的文件列表
multiple	Boolean	true	是否允许多选
