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。

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。
