Is there a way to use “indirect addressing” for JavaScript arrays?

I have a 2d JavaScript array like this:

inventory[1].products

where products is an object with elements {"itemid":"na", "books":10, "dvds":15, "cds":4}

I need to be able to set the itemid with something like

inventory[1].itemid = "books";
indirectaddress = inventory[1].itemid;

and then be able to read the value of the books element with something like:

numberofbooks = inventory[1].indirectaddress;

Is this possible with JS arrays? I done some searching and can’t find anything, unless I am not using the correct nomenclature.

Answer

You can remember the property name in your indirectaddress variable, and use bracket notation to access “books” property via indirectaddress.

indirectaddress = "books";
numberofbooks = inventory[1][indirectaddress];
