Issue
For example, data layer object as follows:
var dataLayer = window.dataLayer || [];
var dataLayer = [{
'some':'thing',
'products': [{
'name': 'Gibson J-200',
'tuning': 'High-G',
'price': 449.75
},{
'name': 'Fender Stratocaster',
'tuning': 'Drop-C',
'price': 1699
}],
'stores': ['Los Angeles', 'New York'],
'employee': {'name': 'Reggie'}
}];
If you create a Data Element in DTM using array notations as the following figure, it returns default value configured as "DLJSDefault" instead of correct value "Gibson J-200":
Environment
Dynamic Tag Management/Activation
Cause
While using the JavaScript Object Data Element type, Dynamic Tag Management does not support array notations.
Resolution
To use array notations, use a Data Element of type 'Custom Script':
You can use the following script for the example scenario:
return window.dataLayer["0"].products["0"].name;
This script returns the value "Gibson J-200" from the example data layer.
