JS打开[保存文件对话框]出错：Automation server can't create object
本人想实现一个客户端js保存Table的数据，用户点击下载后，不提交到服务器，直接使用js读取数据后，打开保存对话框，用户输入路径和文件名然后下载。
遇到如下问题：
1、new ActiveXObject( "MSComDlg.CommonDialog ")
Error：Automation server can 't create object
（IE端，注册表没有问题，COMDLG32.OCX、comdlg32.dll均存在）
另外，new ActiveXObject( "WScript.Shell ")也是同样的错误，但是new ActiveXObject( "Scripting.FileSystemObject ")没有错误！
2、有可能是安全设置的问题么？如果是，如何修改安全设置（windows2003）
3、有其他的实现思路么？（只要不提交到服务器）
[解决办法]
３种可能：
1.在运行里面执行regsvr32 scrrun.dll，如果不行，继续；
2.安装msxml3.dll，再不行，还继续
3.在internet选项里＂安全＂选项卡中涉及到activex的都启用，安全级别设置为 中．再不行，我也没招了．
[解决办法]
用你这种方式当然会被浏览器的安全机制毙掉！
<input type=button value=保存 onclick= "document.execCommand( 'SaveAs ') " />
<input type=button value=另存为 onclick= "document.execCommand( 'Saveas ',false, 'c:\\test.htm ') " />
[解决办法]
那就用FileSystemObject写你想写的内容啊。

梅花雪的思路可以实现LZ所需的效果，因为我也有用过，如保存EXCEL文件

你可以先 var win = window.open(); 然后再 win.document.write(str), 把你的内容写到这个新开窗口中，然后再 win.document.execCommand( 'Saveas ',false, 'c:\\test.htm ')， 最后 win.close() 关掉这个临时窗口。
