I am looking for someone to point me in the right direction with this scenerio.
What I have is a register user form where the user types in their email address.
As soon as they tab/move away from the email address text box, I want some jQuery to compare what the user has typed against my db (by calling some php code and passing in their email address). The php would return true or false (or 0 or 1 etc) - which the jQuery would then display as a success or failure (using the relevant icons).
Does this make sense?
