How can I set up JQuery autocomplete like Stackoverflow's tags input field?

Question

I'm using PHP and I've never really done anything with Javascript or JQuery or AJAX. I'm just wondering if there are any available solutions to accomplish the same effect of auto-completion that SO uses for entering tags.

There are plugins which can handle one word but I haven't seen any that handles multiple words.

Also, I hear JQuery is hosted on google code. Is it a good or bad idea to link directly from that?

Answer 1

I've used

http://plugins.jquery.com/project/autocompletex

Answer 2

The examples here support multiple word autocomplete with jQuery

Answer 3

There are many tutorials out there for doing this with many libraries (not just jquery). If you learn xmlhttprequest object in javascript you won't need to use a library at all for something this simple.

Answer 4

To answer the thing about Google. I have moved over to accessing JQuery via http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js in my sites.

As more people do this means that it's more likely to be cached on user's machines, so my vote goes for good idea.

Answer 5
