Variable path name in object

[kiki]

Hi,

I'm using a function node and want to name the "store path" of the object variable.

At the moment my Output looks like
"element_i"

My actual code looks like this:

But I want to have
element_1
...
element_8

I hope anybody can help me to solve my problem.
Thank you!

The sure fire way is to make a variable for the string value you want to use:

var elemName = "element_" + i;

Then use bracket notation to assign the payload to that key:

msg.payload[elemName] = {...

Bracket notation will interpret a variable into the actual key name and give you what you want.

yessss! That's working

Thank you for your help @madhouse !
