openFileSelect() { // dispatchEvent 向一個指定的事件目標派發(fā)一個事件 this.$refs.fileInput.dispatchEvent(new MouseEvent('click'));} // 多附件上傳 async uploadFile() { let _this = this; this.loading = true; // 獲取上傳的文件，如要限制文件上傳數(shù)量可以 // let files = [...this.$refs.fileInput.files].splice(0,limit); // 也可以在此處拋出文件數(shù)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(shù)據(jù)字段可根據(jù)自己的數(shù)據(jù)格式進行修改。
