Answer 1

Since you tagged it jQuery you can use a jQuery selector:

<script>
  $("#<%=btn.ClientID%>").click(function() {
    //my stuff
  });
</script>

Or if you still want to use OnClientClick:

<asp:Button id="btn" runat="server" OnClientClick="myfunc(this, 'secondvalue', 'thirdvalue')">
<script>
  function myfunc(btn, val1, val2) {
    var buttonRef = $(btn);
  }
</script>
