How does facebook do those forms?





coeus
How is it that facebook forms are so dynamic? Is it a form of javascript?

What I am talking about is like how you can start typing in someones name, and a drop-down list appears below for you to chose from. Then when you do choose one, while staying on the same page that name is added to a list right above the form. Noticed this yesterday while adding a video and was drooling lol.

updated: researching more it seems to be some sort of AJAX app. yay for wikipedia Smile

Its just advanced javascript dom manipulation. The ajax is used to fetch the usernames.

They are the advance developers and throught different test they figure out what should be done and what should not.
