Custom Field value validation to prevent duplication

[WAJDI ALZINATI]

HI, 

I'm trying to use ScriptRunner to make a validation for custom Field value during issue submit so it will check if the field value isn't duplicated in any another issue.

is there any one can help me with required java script 

Thanks

Hi @WAJDI ALZINATI 

You need to create a script validator and need to use Groovy not JS. 

I would recommend take a look at some sample scripts here to get an idea about how to get started with script validators.
