[Zope] calling python scripts, zsql method from onclick

[Laura McCord]

I need three things to occur on an onclick. Is this possible and if so,
what would the syntax be.

This is what I have so far:

tal:attributes="onclick string:showObject(event, '${box}');" 

I need to also include a call to an external method
python:here.macAddress() and call to a zsql method here/deleteMAC

Thanks,
 Laura
