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。
