How to open a save file dialog box in javascript

:confused:

you can't. you can only do it JScript. but even if it was cross-browser I wouldn't show you how ... you could be up to no good! ;)

try this: (ie only)

<button onclick="javascript:document.execCommand('SaveAs','1','fileName.txt')">Click to save</Button>

If you just want to have the user save a file, just make a link to the file on your server, the browser will take care of everything else. If you just want to allow the user to browse the file system. You can use:

<input type="file">

To retrieve a file path from the user.

PS. J-bot I understand where you are coming from, but there are plenty of resources on this stuff, all over.

i know, that's why I don't see the point us adding to it ... for certain exploits anyway.

Yes, but only on the client computer!!!!
To handle a file upload to the server, a server-side process (cgi script) must be running that can handle multipart/form-data submissions.
