Hi

I have an unordered list that is genereated dynamically. It looks similar to the attached code.

Within each list item there is a link and i want to add a number to the querystring in the link, so for example the first link would read post.html?s=2011-07-04-channelports-soft-launch&tid=1
(note the querystring tid=1)
so the second link would have 2 added to read tid=2, third link tid=3 and so on..

Any ideas how to do this with javascript?

thanks


<ul id="mycarousel" class="jcarousel-skin-portfolio">
  <li><a href="post.html?s=2011-06-29-riverside-brand-comms&tid="><img src="/newsite/perch/resources/1315292504riversidethumb.jpg" alt="Riverside Brand Comms" align="left" border="0" /></a><span>List 1</span></li>
  <li><a href="post.html?s=2010-07-20-annual-awards&tid="><img src="/newsite/perch/resources/1315292570awardsthumb.jpg" alt="Annual Awards" align="left" border="0" /></a><span>List 2</span></li>
  <li><a href="post.html?s=2011-07-04-channelports-soft-launch&tid="><img src="/newsite/perch/resources/1315292491cpthumb.jpg" alt="ChannelPorts Soft Launch" align="left" border="0" /></a><span>List 3</span></li>
</ul>

You may use :
$("li a","#mycarousel").each(function(i,el) {
    //var href = $(this).attr("href") + i;  // start with tid=0
    var href = $(this).attr("href") + (i + 1); 
    $(this).attr("href", href); 
    // comment or delete this line (testing purpose)
    alert( $(this).attr("href") );
})
