Question
Can I use an array variable in a Load Rule with a condition such as CONTAINS?
Answer
Short answer: Yes.
Long answer: The JavaScript code generated by Load Rule conditions uses the toString() method which will convert an array to a comma-delimited string. A Load Rule that uses the CONTAINS condition, for example, will convert the variable to a string using toString(), then use indexOf() to find the desired value within the variable.
> product_name = ["Nexus One", "Samsung Razor", "Apple iPhone"]
["Nexus One", "Samsung Razor", "Apple iPhone"]
> product_name.toString()
"Nexus One,Samsung Razor,Apple iPhone"
> product_name.toString().indexOf("Apple")
