使用JavaScript保存文本文件到本地的两种方法

2018年11月30日作者：chenqiangdage 原文

一段使用javascript保存文件的代码。这里方法可以保存指定id元素下的所有html内容；不过这个方法只支持IE浏览器。

function createHtml() {
 try {
  save_record("index1", $("#yhtcprediv").html());
 } catch (e) {
  alert(e);
 }
 }
 function save_record(filename, content) {
 //打开新窗口保存
 var winRecord = window.open('about:blank', '_blank', 'top=500');
 winRecord.document.open("text/html", "utf-8");
 winRecord.document.write(" <div class="introBox section package boxBg02" id="yhtcprediv">" + content + "</div>");         
 winRecord.document.execCommand("SaveAs", true, filename + ".html");
 winRecord.close();
 }

简单好用的JS保存文本文件到本地

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title></title>
<link rel="stylesheet" href="//g.alicdn.com/msui/sm/0.6.2/css/sm.min.css" rel="external nofollow" >
<script type='text/javascript' src='//g.alicdn.com/sj/lib/zepto/zepto.min.js' charset='utf-8'></script>
<script type='text/javascript' src='//g.alicdn.com/msui/sm/0.6.2/js/sm.min.js' charset='utf-8'></script>
</head>
<body>
<!DOCTYPE html>
<html>
<head>
 <meta charset="utf-8">
