根据下列代码:import() { const importInput: any = $('#' + this.className + '_importInput')[0]; this.loading = true; this.common.importByExecutor(this.currentButton.executor, importInput.files[0], this.className).subscribe((response: any) => { importInput.value = ''; if (response.success) { this.dataTable.instance.refresh(); notify({ message: '导入成功' }, 'success', 2000); } else { notify({ message: '导入失败:' + response.message }, 'error', 8000); } this.loading = false; }); } ,写出一个angular批量导入excel代码

好的,下面是一个使用Angular的示例代码,用于批量导入Excel电子表格:
1. 首先,需要安装 `xlsx` 和 `file-saver` 库:
```
npm install xlsx file-saver --save
```
2. 在组件中导入所需的库:
```typescript
import { Component } from '@angular/core';
import * as XLSX from 'xlsx';
import { HttpHeaders, HttpClient } from '@angular/common/http';
```
3. 创建一个用于读取Excel电子表格的方法:
```typescript
onFileChange(evt: any) {
const target: DataTransfer = <DataTransfer>(evt.target);
if (target.files.length !== 1) {
throw new Error('Cannot use multiple files');
}
const reader: FileReader = new FileReader();
reader.onload = (e: any) => {
const bstr: string = e.target.result;
const wb: XLSX.WorkBook = XLSX.read(bstr, { type: 'binary' });
const wsname: string = wb.SheetNames[0];
const ws: XLSX.WorkSheet = wb.Sheets[wsname];
const data = XLSX.utils.sheet_to_json(ws, { header: 1 });
console.log(data);
// 将数据发送到服务器进行处理
this.uploadFile(target.files[0]);
};
reader.readAsBinaryString(target.files[0]);
}
```
4. 将文件上传到服务器端进行处理:
```typescript
uploadFile(file: File) {
const formData: FormData = new FormData();
formData.append('file', file, file.name);
const headers = new HttpHeaders();
headers.append('Content-Type', 'multipart/form-data');
this.httpClient.post('http://your-server-url', formData, { headers: headers }).subscribe(
(response) => {
console.log(response);
if (response.success) {
// 导入成功
notify({ message: '导入成功' }, 'success', 2000);
} else {
// 导入失败
notify({ message: '导入失败:' + response.message }, 'error', 8000);
}
},
(error) => {
console.log(error);
}
);
}
```
请注意,这仅是基本示例代码,您需要根据您的具体需求进行修改和调整。并且需要根据您的具体情况,替换 `http://your-server-url` 为您的服务器端URL。
