Javascript to be stored as clicklogjs in the templates/inc directory.
<script type="text/javascript"><!--
function clicklog() {
// Redirect to the clicklog template with $id of the clicked document.
// We could do something like:
// window.location.assign("../clicklog")
// to redirect to the clicklog template.
// I'm not sure about how we could pass $query and the clicked doc $id to the template.
return true; // To allow following the href link in the <a> tag i.e. document url.
