Get name and not value of a multi-dimensional array?
So, in this scenario I have a multi-dimensional array that is in a module script. I have a localscript that is accessing that module script. It is correctly requiring and getting the sub-array, except it only gives the value and not the name. For example, if I had this array:
local Random = {
Another = {
Blank1 = 1,
Blank2 = 2,
Blank3 = 3,
},
Something = {
Filled1 = 4,
Filled2 = 5,
Filled3 = 6,
},
}
And I wanted to get the names of the sub-array's children. So for example, let's say I was checking if the values was 2, this is what I would do. Also, let's assume for all purposes that the local and everything else is already set-up so that it connects together.
for i, v in pairs(Random.Another) do
if v == 2 then
return v
end
end
However, what I would want it to do is return Blank2, and not the value (or number). How would I do this?

local Random = {
Another = {
Blank1 = 1,
Blank2 = 2,
Blank3 = 3,
},
Something = {
Filled1 = 4,
Filled2 = 5,
Filled3 = 6,
}
}
Your code is pretty accurate expect for the fact that you are returning the value instead of the key (index). In order to return the key, you would have to return (i -- as named in your snippet) instead of v
for key,value in pairs(Random.Another) do
if value == 2 then
print(string.format([[value %s's key is %s]], value, key))
return (key) -- returns the key instead of value at key
end
end
--> value 2's key is Blank2
