page.html部分html代码：
<a href="#" onClick='SaveToLocal()'>temp.txt</a>
<iframe id="ModifyCameraForm" name="ModifyCameraForm" src="about:blank" style="display:none;" width="1" height="1"></iframe>
js代码：
function SaveToLocal()
{
//var src = "bigpicurl.jsp?path=http://172.12.52.2:8080/demohttp/images/1.jpg";
var src = "bigpicurl.jsp?path=http://172.12.52.2:8080/demohttp/temp.txt";
document.getElementById("ModifyCameraForm").src = src;
}
bigpicurl.jsp页面：

原来是下图片的，现在给你下个1.txt也是好用的。我试过了。
注意：目录结构为demohttp/temp.txt。即把page.html,temp.txt，bigpicurl.jsp放在同一个目录，就可以用了。
