Question

I would like to add in my web app ability to add comments to a specific word in the page. Something like the LaTex footnotes.

The UI I had in mind is, each word would be highlighted when the mouse hovers over it (or that the space after it is being highlighted), and when the user clicks, a textbox to enter the comment pops up near the place the comment would appear. After the user entered the comment a little number would appear after this word in the web page, and other users would be able to click on this number and reveal the comment.

The architecture I had in mind is, a client side javascript program that would handle the view. The model and the controller would be on the server. They would save the document in some textile-like format (say, StackOverflow’s question’s format), and would only verify permissions (ie users would only be allowed to add [1] (user-name) … to the document body
).

That’s the architecture and UI I had in mind, but I’m open to new suggestions.

Is there any similar component availible?

Answer 1

The best thing I found so is the digress plugin for wordpress which allows paragraph-based comments.
