前言
本篇主要记录在 Vue项目中 实现附件上传功能,可实现单/多附件上传,识别文件格式并用不同图标展示功能,及控制是否可编辑功能。内容简洁易懂,如有需要可自取。 完整代码点击这里click
核心代码
<div class="upload-flie-btn"> <div class="btn-tips" @click="openFileSelect" v-show="editFlag">上传附件</div> <input style="display: none" type="file" ref="fileInput" multiple="multiple" @change="uploadFile" /> </div>
openFileSelect() { // dispatchEvent 向一个指定的事件目标派发一个事件 this.$refs.fileInput.dispatchEvent(new MouseEvent('click')); } // 多附件上传 async uploadFile() { let _this = this; this.loading = true; // 获取上传的文件,如要限制文件上传数量可以 // let files = [...this.$refs.fileInput.files].splice(0,limit); // 也可以在此处抛出文件数量超出限制的提示 let files = [...this.$refs.fileInput.files]; if (!files || !files.length) { return; } // 后端接口地址 let url = `url`; // 一起请求后端接口 Promise.all( files.slice(0, files.length).map((file) => { const data = new FormData(); data.append('file', file); return request.post(url, data, { headers: { 'Content-Type': 'multipart/form-data', }, }); })Ï ).then((res) => { _this.loading = false; _this.$refs.fileInput.value = null; }) .catch((err) => { console.log(err); }); }
文件展示部分代码
此部分使用了 vux 组件库,该部分处理了word、excel、ppt、pdf、image、txt格式的文件展示问题,其它类型的文件均展示位“其它”,也可以自行更换矢量图,iconfont 中可以查找到。遍历的数据字段可根据自己的数据格式进行修改。
