图床项目进度（三）——文件展示页

只会写bug的靓仔2023-09-13 12:06

前言

该项目作为一个类网盘项目，主要包括上传下载，引用，预览等功能。

大致功能：

  1. 图片预览

这里的图片预览我使用的一个插件

const state: any = reactive({

j 复制代码 
  image: 'https://pic35.photophoto.cn/20150511/0034034892281415_b.jpg',
  index: 0
});

const previewEvent = () => {
  preview({
    images: state.image
  });
};
  1. 上传图片
bash 复制代码 
<el-button type="primary" size="small" @click="dialogVisible = true" :icon=Upload>上传图片</el-button>
  1. 几个自定义标签
bash 复制代码 
<el-table-column>
<!--        几个自定义图标-->
        <template v-slot="{row}">
          <div v-if="isPicture(row)" >
            <el-button  type="primary" round size="small" style="margin-right: 50px" @click="previewEvent">预览</el-button>
            <el-tooltip class="item" effect="dark" content="引用" placement="bottom-start">
            <el-button type="text">
              <el-icon>
                <Link/>
              </el-icon>
            </el-button>
           </el-tooltip>
          <el-tooltip class="item" effect="dark" content="下载" placement="bottom-start">
            <el-button type="text">
              <el-icon>
                <Download/>
              </el-icon>
            </el-button>
          </el-tooltip>
          <el-tooltip class="item" effect="dark" content="删除" placement="bottom-start" >
            <el-button type="text"><el-button type="text">
              <el-icon>
                <Delete/>
              </el-icon>
            </el-button></el-button>
          </el-tooltip>
          </div>
        </template>
      </el-table-column>
  1. 文件展示

vue组件源码：

bash 复制代码 
<template>
  <div>
    <div class="bt">
      <el-button type="text" size="medium" @click="back" v-if="path.length >= 1">
        <el-icon>
          <ArrowLeft/>
        </el-icon>
        返回上一级
      </el-button>
      <el-button type="primary" size="small" @click="dialogVisible = true" :icon=Upload>上传图片</el-button>
      <el-button size="small"  @click="addFolder = true">
        新建文件夹
      </el-button>
      <el-dialog
          title="输入文件名字"
          v-model="addFolder"
          width="20%"
