I am developing an internal website for managing company resources. The user sees very few full page refreshes. Therefore, when they click "Save" to save their changes, they don't get a refreshed page to show them the button was clicked and some action was taken.
Right now, the user can make changes, click Save and not know if the click was successful because the page remains the same (except with a Changes Made listbox at the bottom). I anticipate this will lead to users just clicking save 4 or 5 times to make sure.
Does anyone have a good idea/example of a method (AJAX perhaps?) of conveying to the user "Yes, I see you clicked the 'Save' button and acted on it"? It doesn't need to show if it was successful or not (errors are displayed in other ways). I just need the user to know clearly and quickly that their button click registered.
