document.location...

[admin]

I'm trying to change the document.location without reloading the page. Is there anyway to do that? Say it is <!-- m --><a class="postlink" href="http://www.somedomain.com">http://www.somedomain.com</a><!-- m --> and you want to change it to <!-- m --><a class="postlink" href="http://www.somedomain.com?test">http://www.somedomain.com?test</a><!-- m --> Is there some way to do that without reloading the page? Thanks.
