Parameter 'this'

[carlos@agpsoftware.com]

Hi,

I'd want to fire a button with this code, but from antview, outside the button. I fon't figure out how to sustitute 'this' in call.

     onmousedown="iniciarBusqueda('button1',this);"

id="viewns_Z7_AVEQAI930OBRD02JPMTPG21004_:form1:button1"
type="submit"
name="viewns_Z7_AVEQAI930OBRD02JPMTPG21004_:form1:button1"

Thanks in advance.
Regards.
