best-practices

Hello everybody,

I have multi-step form and user can navigate to any page to modify or add information. There is a menu that shows progress and steps user completed. This menu allows to navigate to any step user completed or going to complete.

Inspite of big button "Save and Continue" some users click this menu to navigate further. I have to check - if values have changed in a form and ask: "Save changes? Yes/No".

What is the best way (with minimum code) you suggest me to check if form values have changed.

Thank you in advance!
