javascript - Access the content of a variable who's name is in another variable -

this question has answer here:

i have 2 variables, 1 holds info object, , named extra_info + id of object. other holds name variable:

selector = 'extra_info' + subscid;

i trying access data stored in variable holds info, can't seem access it. stupid, know :-)

edit: so, name of variable in end need access is:

extra_infoxxxxx

where xxxxx stored in subscid.

no quotes:

selector = extra_info + subscid;

or, , i'm loathe suggest because it's red flag of bad design, can use eval():

selector = eval('extra_info' + subscid);

edit

it sounds should stored extra_info in ~~array~~ object, subscid ~~indexes~~ properties!

to access, extra_info[subscid].
