用户需求: 将一些指定数据进行导出;
(注意:该方法当数据量过大是会使浏览器崩溃,建议小数据量使用)
话不多说,直接上码:
<!DOCTYPE html>
<html >
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>xls导出</title>
<link rel="stylesheet" href="layui/css/layui.css" target="_blank" rel="external nofollow" media="all">
<script src="https://code.jquery.com/jquery-3.1.1.min.js"></script>
</head>
<body>
<button onclick="xls();" style="margin:0px 500px">导出按钮</button>
</body>
<script>
function xls(){
let list = [{PlayerId:"小宝"},{PlayerId:888888},{PlayerId:"小er"},{PlayerId:7777}];
let str = `序号,用户ID\n`;
//增加\t为了不让表格显示科学计数法或者其他格式
for(let i = 0 ; i < list.length ; i++ ){
let PlayerId = list[i]["PlayerId"];
let index = i+1;
str+=`${index + '\t'},`+`${PlayerId + '\t'},` +'\n';
}
//encodeURIComponent解决中文乱码
let uri = 'data:text/xls;charset=utf-8,\ufeff' + encodeURIComponent(str);
//通过创建a标签实现
var link = document.createElement("a");
link.href = uri;
//对下载的文件命名
link.download = "韦大宝统计.xls";
document.body.appendChild(link);
link.click();
document.body.removeChild(link);
}
</script>
</html>
