T.J. Crowder:
Question:
Do we need a wiki with user-generated content?
We should:
just move all of the relevant content to the Prototype website and make sure
the
process for contributing to the website is well-publicized, easy, and
efficient
I think the site needs an integrated
I think:
requestHeaders: ['Accept-Encoding', '']
should be:
requestHeaders: {'Accept-Encoding': ''}
'msg' is not explicitly defined in your post, it is set somewhere,
right?

Are you sure your servlet is responding with the proper headers. Try
creating a small self-contained minimum test case which fails. Using a
relative URL ensures that it is from the same origin as the loading
page. -Mark

I worked on something similar, 3 columns, portlets can be moved from
column to column with asyncronous callbacks to the server to update
portlet order. It's simple and only requires prototype/scriptaculous.
A good reason to get out of the habit of using document.write, is that
it is NOT supported by XHTML.[1]

..move scripts to the bottom of the page if they are deferrable.
I think you should read more into the last word of this quote. If your
application is dependent on the javascript for basic functionality
then those scripts are not deferrable. If the scripts just added eye

Just to clarify, In case some other noob sees this. You EITHER use a
script tag to include an external .js file OR you xml escape inline
code.
NOTICE: you must add two forward slashes so old browsers ignore the
CDATA tags.
Example:
script src=prototype.js type=text/javascript/script

So, your options are:
1. Proxy the request to feed yourself
2. Let Google or someone else proxy it for you

many users loading many feeds simultaneously.
I use the Google RSS Feed API and let them do the heavy lifting. I

Shouldn't that check happen in the library? I don't think I've ever

First thing I noticed was the display:none inline style of
#autocomplete_choices is going to make any updates hidden. I've never
actually used this feature myself, maybe unhiding this div is
automatic.

I usually respond with a JSON object that at least provides some debug

It looks like your on your way to a solution. It's one thing to post
technical questions, your first post was great. You'll probably see

(Event.observe)
Before asking for code, Ask yourself, Am I a help vampire?
Maybe filter should be an alias of findall for arrays, but shouldn't
it really return a hash for hashes? Especially if thats its behavior
in ruby, which Prototype is supposed to be modeled after.

Hi Brad,

You should make it injections safe, for example if using PHP:
$safe_id = mysql_real_escape_string($_REQUEST['id']);
$query = SELECT last_name, first_name FROM people WHERE
last_name='$safe_id' ;

Just a guess. Maybe try waiting for the DOM to load before calling
your function:
new Ajax.Autocompleter(autocomplete, autocomplete_choices, ./

Like this:
Event.Observe(window,'load',function(){
new Ajax.Autocompleter(autocomplete, autocomplete_choices, ./

});
Ajax.Request and methods that inherit it(like autocompleter) accept
JSON encoded objects as parameters (AFAIK)
