Update:

Time certainly changes things ;-) When I first answered this question IE8 was the latest IE browser available (Nov 2010) and thus there was no cross browser way to accomplish this without a round trip to the server, or using a tool requiring Flash.

@Zectburno's answer will get you what you need now, however for historical context be aware of which IE browsers support which feature.

• btoa() is undefined in IE8 and IE9
• Blob is available in IE10+

Be sure to test in the browsers you need to support. Even though the Blob example in the other answer should work in IE10+ it doesn't work for me just clicking the link (browser does nothing, no error)... only if I right click and save target as "file.csv" then navigate to the file and double-click it can I open the file.

Test both approaches (btoa/Blob) in this JSFiddle. (here's the code)

Original Answer:

I don't think there is an option available for this.

I would just adjust your code such that if Flash 10+ is detected (93% saturation as of September 2009) on the user's system, provide the Downloadify option, otherwise fallback to a server-side request.
