Field input validation to check for max chars between the pre filled field value

[Lakshmi S]

Hi Team,

We have a custom field called the "Desired Product Account name" field with a single-line text box (The field should take "alpha numeric"). I need the validation to check for max chars (maximum is 20 chars between "AWS" and the environment of nonprod/prod)

Example :  aws |[Text box with 20 Max chars]| nonprod/prod

 It needs to be clear that we will prepend "aws" to the front of the requested name, and "nonprod" and "prod" to the end of the names

sample :  awsexamplenonprod  , awssampleprod, etc

Is there any possibility with script runner or JMWE addons ?

Hi @Lakshmi S 

You can use a JMWE Scripted Validator with code like this:

issue.get("Desired Product Account name")?.toLowerCase() ==~ /^aws\w{1,20}(prod)|(nonprod)$/

Hi @David Fischer ,

How to prefilled the these values in the field ?

aws and nonprod/prod ? the validation for in between those 20 chars max. Should i add default value of that to the field ?

aws |[Text box with 20 Max chars]| nonprod/prod

Not sure how you can pre-fill the value - I guess you could have a default value showing the "template" for the value. But the validator will only validate that the value entered in the field is correct: it starts with aws, it ends with either prod or nonprod, and in-between is 1 to 20 alphanumeric characters.

Alternatively, you could use a post-function to automatically add "aws" and "prod" or "nonprod" to the value that's input in the field by the user, and have the user only input the 1 to 20 characters in-between.

Thank you @David Fischer . The JMWE script validation is perfectly working, and the post function suggested by you for pre-fill value.

Hi @Lakshmi S scriptrunner could handle this with a custom scripted validator you could probably even put it into a screen behaviour and address the validation before the end user hits submit(create/update) on the issue.
