[OpenLayers-Users] map.getLayersBy() Question

[Bill Thoen]

I'm trying to use getLayersBy() to select layers for a getFeatureInfo 
tool, and I can get it to work for one criterion : 
map.getLayersBy("queryable", true) , but suppose I want to use two 
criteria, like where queryable and visibleity are BOTH true? I can't 
seem to get the right syntax.

TIA,
- Bill Thoen
