JQuery Ajax adding hash in the url
Here is a working example (not considering Struts2):
<html><body><a id="123" href="">Add Hash</a><script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script><script>$(document).ready(function() { $("a").click(function(e) { window.location.hash = $(this).attr("id"); e.preventDefault(); });});</script></body></html>
