Question

I've been trying to put this in place, exactly as this guys are doing http://support.3dsellers.com/qa/ but I can't find a plugin for this, any one can help? I've already search on this forums without luck. Thanks

Answer 1

What they have done is replace the "onchange" event in javascript with "onkeyup". Most likely they've just changed the core code in pages/ask.php line 213. It may be possible to do this in the theme but it's more complex.

However, note that this does an AJAX request on every single letter typed, so there's a possibility it could overload your server.

I totally agree, I have another software using this feature and when multiple people online and using that feature overloads the server and my host keep asking me to remove that feature... :)

I have done this "hack" as well. Just make sure that you only trigger the ajax call when there is a minimum of x characters plus optional, not more than 1 time per 3 seconds or so.
