dynamic collections with node.js and monogjs

i try to find a way to use vars for mongojs collections. The data are dynamic and also the db.VAR.find(); must be dynamic. Is there a solution for that problem. I searched here and google, but there is nothing. I hope you can help me.

Example:

var var1 = "game12"; var var2 = "game34";

db.var1.find({name: x},function(err, datas) { if( err || !datas ) { console.log("Problem finding data :" + err); }else{ datas.forEach( function(curData) { console.log(curData); }); } });

db.var2.find({name: x},function(err, datas) { if( err || !datas ) { console.log("Problem finding data :" + err); }else{ datas.forEach( function(curData) { console.log(curData); }); } });
