periodically autosave form

Would someone show how to implement a periodical save of a form in the background? Same kinda thing that gmail does. I would like to autosave a form ajax wise so a technician in the field would have it saved off in case of a wireless disconnect while filling out a form. thanks.

I would guess on doing the periodically call remote but how do you submit the form?

A caveat, It has to be done with the form already having been created. So doing an observe form with a form id will not work as the form id id being generated by rails as it is in edit mode.

I am not sure about your situation, but I would use observe_form set and :frequency to seconds at which changes to this field will be detected. This should work with the existing form.

See the documentation. http://api.rubyonrails.org/classes/ActionView/Helpers/PrototypeHelper.html

In this case, he does not even have to observe the form.

He can just call a script on page load which shoots off an Ajax submit and update on the form every minute or so.
