Removing data from a variable

I have a variable which carries information but i want to be able to remove the information some how.

I tried to set the .length = 0 but that didn't seem to work...

The current data of the variable (example data is):

var data = {"1":{"7":["310"],"22":["309"]}}

In english that is:

var data = {"X":{"Y":["ID"],"Y":["ID"]}}

So if i wanted to remove:

X: 1 Y : 22

The result of data would be:

var data = {"1":{"7":["310"]}};

This is what i tried:

data[X][Y].length = 0;

But that doesn't seem to work, any one understand how to do it?
