Dynamic Variable in JS

Question

I have this code :

var dynamicVarName = id;

var percentage = res.parkeren[0].dynamicVarName.percentage;

DynamicvarName can have different values, but when i call this in the var percentage it's not working.

How can i get the dynamic variable in the array / object?

Answer 1

You need the bracket notation for the access:

var dynamicVarName = 'id';
var percentage = res.parkeren[0][dynamicVarName].percentage
