[jQuery] referring to an array with a specific name

[jQuery] referring to an array with a specific name


Hello guys,
I have a drop-down menu with 2 values ("a" and "b") and I have on my
script 2 arrays ("a" and "b").
Is there a way to select an array according to the drop-down value. I
mean if I store in a variable the selected value
var selected_value = $("#dropdown").val();
is there a way to refer to the array with the same name of the value
stored in selected_value?
Thanks and have a nice day!
