Simple Javascript (and CSS) for Reputation

[Martindale]

On our chat page (http://www.roleplaygateway.com/chat.php), the messages currently come in, with the newest at the top. We'd like to invert that, and put the newest messages at the bottom. Should be a very simple JS fix.

For an additional rep point, we need to condense each message to have less padding and margins, make them closer together.

Firefox's Firebug and Web Developer extensions may help. A CSS fix is easy, but fixing the Javascript to update the page with the right code isn't. :)

I might even give a cash bonus if the solution is nice and pretty. :)

Oh, slight update. We moved the chat page back to our old page, until we get the issues worked out. You can find the same page on the bottom of our roleplaying index (http://www.roleplaygateway.com/index.php). Thanks in advance to whoever helps!

On around line 191, after this:
results = xmlHttp.responseText.split('---');
add:
results = xmlHttp.responseText.split('---');
results = results.reverse();

Couldn't find the css styles at all :| well i found some, but none of the id's and classes associated with the chat, from what i can tell it uses the same styles as your forum, so unless you make new ones, if you changed the shoutbox css then the forum would as well.

Could be wrong though :p

JS didn't work, here's the relevant code....

Try reversing the order of the line in boldface, like the following, and include the new line, as shown:



else
{
document.getElementById(fieldname).innerHTML = document.getElementById(fieldname).innerHTML + results[0];
document.getElementById(fieldname).scrollTop = document.getElementById(fieldname).scrollHeight;
}

function handle_return()
{
if (xmlHttp.readyState == 4)
{
if (type != 'delete')
{
results = xmlHttp.responseText.split('---');
if (results[1])
{
if (last_id == 0)
{
document.getElementById(fieldname).innerHTML = results[0];
}
else
{
document.getElementById(fieldname).innerHTML = results[0] + document.getElementById(fieldname).innerHTML;
}
last_id = results[1];
if (results[2])
{
document.getElementById('whois_online').innerHTML = results[2];
last_time = results[3];
if (results[4] != read_interval * 1000)

That code posts the new messages to the bottom, but does not display old messages bottom up.
