Remember Selected Value in Custom Checkout Fields

[westdavidr]

I have a survey question in the shipping/billing page of my store, and I can't figure out how to get it to remember the selected option if the customer has to go back to that page to make changes or whatever. Any help?

The only way you could do this is to add JavaScript to the checkout page to set a cookie with the setting of the Custom Checkout Field in it, and change the code that creates the Custom Checkout Field from straight HTML to JavaScript that reads that cookie and writes out the HTML for the field with the correct defaults in it depending on what it found in that cookie.

Yeah, but setting a cookie is no easy task! But if that's the only way, I guess I'll look into it. Thanks.
