How do I check if a string contains a substring in appway script?

Question

The CONTAINS($val1, $val2, $delim) function in AppwayScript checks whether a delimiter separated string contains a certain value as a substring.

So, e.g.:

CONTAINS('a|b|c', 'b', '|') == true

but

CONTAINS('aa|bb|cc', 'b', '|') == false

How do I perform a simple string inclusion test in AppwayScript?

Answer 1

Instead, try:

MATCH('aa|bb|cc', 'b')
