I'm working on a site that has comments enabled, with no moderation. After commenting on a page, your comment shows up on that page, and I've added a Facebook share icon below each comment that allows you to share "website.com/page?comment=10" (or whatever your specific comment ID is). You could also potentially share someone else's comment if you wanted to.
I would now like to include a pop-up message after a user submits a comment, which says something like "Thanks for commenting! Would you like to share this comment on Facebook?" and then allows you to share that same URL (so that it points directly to your comment on the page).
Does anyone have any advice on how to proceed?
