prompting user to save

asookazian Apr 29, 2009 10:05 PM

Assume there is a form in a JSF/facelet. User enters some data in a HtmlInputText field. user navigates to a different page via link in menu, s:link, etc. User does not click submit button prior to navigation.

How can we trap for this scenario and display modalPanel as a warning that "if you go to different screen, all unsaved work will be lost"?

is there a way to detect unsaved work in JSF/RF/Seam?

Hi,

There's no integrated solution. The basics: use cancelable Javascript "onbeforeunload" event to track user leaving page; "onchange" event bound to all form elements to track changes. Take a look: http://www.4guysfromrolla.com/webtech/100604-1.shtml - he saves form values before processing - not using onchange. For ease of implementing this I'd suggest to use jQuery library that is bundled with RF.
