Use javascript/jquery to append URL?
<p>Is it possible to use javascript/jquery to append something on the end of a url when a link is clicked?</p>

<p>For example, I have 5 tabs on a page (product.php), when I click a tab, then that tab opens.  What I want to do is have the URL change to product.php#tab-3 (or whichever number tab is clicked) when you click on it.</p>

<p>The reason I am doing this is so that users will be able to bookmark the page on a specific tab.</p>

<p>Thanks</p>
