JSP中将textarea的内容另存为一个txt文件方法如下:
<HTML>
<HEAD>
<META content="text/html;charset=gb2312" http-equiv="Content-Type">
</head>
<body>
<script type="text/javascript">
function saveas()
{
var winSave = window.open();
winSave.document.open ("text/html","utf-8");
winSave.document.write (document.getElementById("dataarea").value);
winSave.document.execCommand ('SaveAs',true,'test.txt','.txt');
winSave.close();
}
</script>
<textarea id="dataarea">
Test, just a test
</textarea>
<input type=button value="另存为" onclick="saveas()">
</body>
</html>

String client = request.getHeader("User-Agent");
String appachName="下载.txt";
if (client.indexOf("MSIE") > 0) {
response.setContentType("application/octet-stream;charset=utf-8");
appachName = new String(appachName.getBytes("GBK"),"ISO-8859-1");
appachName = "attachment; filename=\"" +appachName+ "\"";
} else {
response.setContentType("application/octet-stream;charset=UTF-8");
appachName = new
String(appachName.getBytes("utf-8"),"ISO-8859-1");
appachName = "attachment; filename=\"" +appachName+ "\"";
}
response.setHeader("content-disposition", appachName);
response.setHeader("Cache-Control", "must-revalidate");
String content = request.getParameter("textarea 的 Name 值");
OutputStream fos = response.getOutputStream();
fos.write(content.getBytes());
fos.flush();
fos.close();
