1. Ignoring for now.
2. The template link is special, so I've added a custom confirmation that says "Your changes will be overwritten" or something to that effect
3. Done.
4.1 Not yet done
4.2 I've added some rules so that the popup only appears if:

• A draft has been saved
• If not, whether the content has changed (adding text and then deleting it counts as changed).

4.2 - Further - We already save a draft for content types with drafts on page unload, so the hasContentChanged check won't help for these types because it will always return false. Potentially we could now skip the draft save and let the user make the decision, or just stick the draft save after the user presses Cancel.

3. You can add custom text. Just return the message from the event handler or add it to the event depending on which browser you're in. https://developer.mozilla.org/en/DOM/window.onbeforeunload

4.2 - We have a hasContentChanged() function in page-editor.js that handles both the RTE and Wiki Markup. Regardless of user setting I think the message shouldn't appear if there is nothing to lose, this would benefit from some UI flag like "Editing..." next to the Save button showing that there were unsaved changes.

1. I don't think this is terribly important.
2. That's interesting. For this to work, we probably need smart rules on when to show it. You don't want it to pop up all the time when trying out different templates. Better not to have it on templates than to make it too annoying. If at all, it should propably only pop up for the first template change in a session?
3. AFAIK this is a hardcoded message by the browser: "The default statement that appears in the dialog box, "Are you sure you want to navigate away from this page? ... Press OK to continue, or Cancel to stay on the current page.", cannot be removed or altered.",. see http://msdn.microsoft.com/en-us/library/ms536907(VS.85).aspx
4.1. I assume this is primarily important when developing (or testing), but yes, a setting would be good
4.2 If there is a way to do this (draft-saving does this), we should try to use the same mechanism.

1. This has not been done for Profile, as specified above
2. The confirmation does not appear when templates are available, and the user clicks on the link "Select a page template to start from" after entering text
3. The confirmation text says "Are you sure you want to navigate away from this page?" There is no clue given about why you might not want to - that is: it would be a better message if it said something like "...because you still have unsaved changes..."
4. The confirmation can be quite annoying. Is it possible to:
   1. Provide a configuration setting to turn the feature off
   2. Only show the confirmation if there in fact unsaved changes to be lost. i.e. user can click add/edit, not enter anything, and then cancel the edit by navigating away, without being prompted to confirm.

Assigning this to you since Chris is no longer.

Done. We use the onbeforeunload handler, as documented here:

http://msdn.microsoft.com/en-us/library/ms536907(VS.85).aspx

Tested in IE6, IE7, FF2, FF3, Safari 4.

Unfortunately due the nature of this handler, it can't really be tested with Selenium.

Just to make sure: This specifically applies to blogposts and comments as well. And anywhere else where you can edit larger chunks of text and accidentally leave the screen (e.g. when editing your profile)
