I am trying to find a configuration snippet that will allow me to configure an EX3300-24T switch to mirror vlan traffic to an analyzer connected to a local port on the switch. I am running Junos 12.3R6.
Sorry, I missed that this input was a vlan interface. I don't think this is possible, the port mirror options seem to only take physical interfaces for input selection where vlans can be used for output in order to forward the mirror to a remote switch port.

I think you will find that port mirroring on the EX switch is an exercise in frustration, to say the least. The hardware is limited as to what can be done. Your best bet is the link that spuluka suggested, craft your filters to be inclusive of all traffic on that VLAN, and mirror every port that is a member of that VLAN.
