本篇主要記錄在 Vue項目中 實現附件上傳功能，可實現單/多附件上傳，識別文件格式并用不同圖標展示功能，及控制是否可編輯功能。內容簡潔易懂，如有需要可自取。 完整代碼點擊這里click

<div class='upload-flie-btn'> <div @click='openFileSelect' v-show='editFlag'>上傳附件</div> <input type='file' ref='fileInput' multiple='multiple' @change='uploadFile' /></div>

openFileSelect() { // dispatchEvent 向一個指定的事件目標派發一個事件 this.$refs.fileInput.dispatchEvent(new MouseEvent(’click’)); } // 多附件上傳 async uploadFile() { let _this = this; this.loading = true; // 獲取上傳的文件，如要限制文件上傳數量可以 // let files = [...this.$refs.fileInput.files].splice(0,limit); // 也可以在此處拋出文件數量超出限制的提示 let files = [...this.$refs.fileInput.files]; if (!files || !files.length) { return; } // 后端接口地址 let url = `url`; // 一起請求后端接口 Promise.all( files.slice(0, files.length).map((file) => {const data = new FormData();data.append(’file’, file);return request.post(url, data, { headers: { ’Content-Type’: ’multipart/form-data’, },}); })Ï ).then((res) => {_this.loading = false;_this.$refs.fileInput.value = null; }) .catch((err) => {console.log(err); }); }文件展示部分代碼

此部分使用了 vux 組件庫，該部分處理了word、excel、ppt、pdf、image、txt格式的文件展示問題，其它類型的文件均展示位“其它”，也可以自行更換矢量圖，iconfont 中可以查找到。遍歷的數據字段可根據自己的數據格式進行修改。
