[jQuery] Reading a querystring to determine an action - possible?

[Bruce MacKay]

Hi folks,
I'm working on a site that, by default, has a RHS sidebar.  I want to 
be able to selective hide that sidebar based on the value of a querystring.

More specifically, there are times when I need the "whole" page to 
display a large table, so when I submit a post or call to the server 
from the page to generate/load the table, I intending adding a 
querystring variable that, when the page is refreshed and the table 
is about to be loaded, jQuery will hide the sidebar (i.e. display:none;)

Is this possible?  I cannot find any examples in the tutorial section 
of the site or find previous posts in this list's archives.

Of course, I can achieve what I'm seeking by having server-side 
conditional includes based on a querystring value, but I'd like to do 
this the jQuery way if possible.

Thanks/Bruce
