Make An Array Inside A Loop?

I have this loop:

for (var j = 0; j < gmarkers.length; j++) {
gmarkers[j].hide();
elabels[j].hide();
map.closeInfoWindow();

[Code]....

which was useful for passing the p variable when it was just one number.

but now I need to get that number every time j gets set (I understand that the j gets overwritten each time the loop goes through).

What would be ideal is if p could become an array, the contents of which match the values that j has passed though during the loop cycle.

I thought var p = new Array (j); minght do the trick, but obviously not...
