Event Forwarding -question

[arunkumark2]

Hi All,

I have a issue regarding event forwarding. We are using the Web SDK on our e‑commerce website, and through this interaction call, I am creating a Data Element using the "arc.event.xdm" path name. Now, I need to create another Data Element using Custom Code. How can I build this custom code (using getDataElementValue)?

Example- 

let locale = getDataElementValue('xdm_environment_dc_language');
const match = (typeof locale === 'string') ? locale.match(/-_$/) : " ";
const region = match ? match[1].toUpperCase() : ''
return region;

 
It returns empty string instead of locale value, Anyone from community facing this kind of scenario ?

Hi @arunkumark2 

You can directy reference the XDM in the data element - can you try like below?

const locale = arc.event.xdm.environment.dc.language

Don't forgot to publish the dataelement

Hi @Vinoth_Govind,

The locale variable already holds a value like "en-us", but I need only the second part of the value, i.e., us. Can I use Custom Code to extract just "us"?

[Vinoth_Govind]

Try this 

const match = locale.match(/[_-]([a-zA-Z]{2})$/);
if (match && match[1]) {
  return match[1].toUpperCase();
}
return "";

Above code will work even if value is "us_en".
