how to use variable in a variable name

Question

so i am working with a json variable like this:

opponentInvData.item1

it contains items 1 through 6

i need to access the different items dynamically and set them to null. itemNum is the specific item i need to access. im trying to use the eval function

var itemNum = 2;
eval(opponentInvData.item + itemNum + ' = ""');

needless to say, it's not working, any ideas?

You need to add quotations around opponentInvData.item in the eval call, otherwise it will use the current value. You shouldn't use this approach regardless - just saying what is wrong with your code. — Cristian Sanchez

opponentInvData['item1'] = "my item"

is the same as

opponentInvData.item1 = "my item"
