I am trying to implement Autocomplete in a text area (similar to http://www.pengoworks.com/workshop/jquery/autocomplete.htm).
What I am trying to do is when a user enters a specific set of characters (say insert:) they will get an AJAX filled div with possible selectable matches.
In a regular text box, this is of course simple, but in a text area I need to be able to popup the div in the correct location on the screen based on the cursor.
Can anyone provide any direction?
You can get the caret using document.selection.createRange(), and then examining it to reveal all the information you need (such as position). See those examples for more details.
