1.效果展示
上传数据前
上传数据后
或者
2.下载
npm install xlsx@0.17.0
如果一直报关于xlsx的read的错误,这里是因为xlsx的0.18.0版本已经没有read属性了,所以最好是使用0.18.0版本以下的xlsx。
3.js文件
excel.js文章来源:https://www.toymoban.com/news/detail-634357.html
import { stringify } from "json5";
// 按照二进制读取文件
export function readFile(file) {
return new Promise((resolve) => {
let reader = new FileReader();
reader.readAsBinaryString(file);
reader.onload = (e) => {
resolve(e.target.result);
};
});
}
// 字段对应表
export let character = {
staffName: {
text: "员工姓名",
type: "string",
},
sex: {
text: "性别",
type: "string",
},
idNumber: {
text: "身份证号",
type: "string",
},
staffEmail: {
text: "员工邮箱",
type: "string",
},
phone: {
text: "电话号码",
type: "string",
},
jobPreference: {
text: "工作偏好",
type: "string",
},
timePreference: {
text: "时间偏好",
type: "string",
},
datePreference: {
text: "时间段偏好",
type: "string",
}
};
// 时间字符串格式化
export function formatTime(str, tpl) {
let arr = str.match(/\d+/g).map((item) => {
return item.length < 2 ? "0" + item : item;
});
tpl = tpl || "{0}年{1}月{2}日 {3}时{4}分{5}秒";
return tpl.replace(/\{(\d+)\}/g, (_, group) => {
return arr[group] || "00";
});
}
utils.js 实现加载文章来源地址https://www.toymoban.com/news/detail-634357.html
// 设置异步延迟间隔
export function delay(interval = 0) {
return new Promise((resolve) => {
let timer = setTimeout((_) => {
clearTimeout(timer);
resolve();
}, interval);
});
}
