Simple Javascript to a parameter to all link in a page.
<script type="text/javascript"> jQuery(document).ready(function ($) { $(function() { $("a").attr('href', function(i, h) { return h + (h.indexOf('?') != -1 ? "&var=value" : "?var=value"); }); }); }); </script>
i use this to create demo site 🙂
You can add this simple JQuery script in footer.
