how we can pass arguments to Jquery functions...

I hav this code:<td><a href="#" id="prepare" style="font-size: 11px; width:70%; height:20px" >Prepare</a></td>

$('#prepare')
        .button()
        .click(function() {

            // clientData="?perform=viewSiteDataDetails&searchingRefNo="+referenceNo;
           addTab();
