How to call function

How to call function


This is a dumb question but I don't see an example in JQuery docs.
How do you set the onclick event for something like this
I have this JQuery code (plugin) in my page:
<script type="text/javascript">
<!-- Google Analytics Tracking Code -->
$.gaTracker('<%=
ConfigurationSettings.AppSettings["GoogleAnalyticsProfileID"]%>');
</script>
<a href="../../downloads/portaltest_googleanalytics.pdf"
onclick=>TestPDF for Google Analytics</a>
On click should call .gaTracker
