How Can I Parameterize Custom Labels in Lightning?

Question

Good afternoon everyone,

Now that custom labels are supported in Lightning. Has anyone had any success parameterizing them like the person did in this post? I'm trying to pass an attribute value as the label name.

Based on the post I tried the following syntax variations and cannot get it to work. I keep receiving a syntax error:

{!$Label.c.[v.labelname]} {!$Label[v.labelname]} {!$Label.[v.labelname]}

Answer 1

Won't work right now.

1. We don't support map[variable] de-referencing.

2. Labels are going to be pre-parsed from the file to see what is necessary, and to do that it's essentially a regular expression $Label.(\w).(\w) -- (Note: not the actual regex) which we use to send down the labels with. If you have it as a variable we won't know which labels to send.

3. If you did in fact have the label, you could do this in Javascript.

   $A.get("$Label." + cmp.get("v.labelname"));
