How to get current timeline frame number using jsx?

Thanks for the link!

Clarification: I was looking for current frame on Video Timeline. OP there mentions that he had found how to get that so I searched around a bit more and found this thread: Re: Can I read/write inpoint and outpoint of clips in a Video Group with scripting? They have the following function, I have not tried it out yet but it looks like it should work.

function getCurrentFrame(){

   try{

      var ref = new ActionReference();

      ref.putProperty(charIDToTypeID('Prpr'), stringIDToTypeID('currentFrame'));

      ref.putClass(stringIDToTypeID('timeline'));

      var desc=new ActionDescriptor();

      desc.putReference(charIDToTypeID('null'), ref);       

      var TC=executeAction(charIDToTypeID('getd'), desc, DialogModes.NO);

      return TC.getInteger(stringIDToTypeID('currentFrame'));

   }catch(e){return null;}

};
