How to generate a link with scriptrunner

[lightam]

Hello together, 

i want the following:

- The user creates an issue

- When he fill the custom Field TicketID with the value "AB1234"

- I want that after the user switch to another field the value of field TicketID switch to
"www.myticketsystem.com/AB1234"

How is this possible with scriptrunner? 
Do I need a listener or a custom script field?

Hi @lightam 

Is there any particular reason you need it to change as the issue is being created? This would be quite straightforward to do in a Create Post Function where:

• Groovy Post Function script reads the current value in the field
• Prepends it with "baseUrl/browse/"
• Writes it back.

Note: I use the "baseUrl" always rather than hard coding the URL of the site; that way if it changes OR I move over to my test instance, it picks up what the system thinks it is and not what I told it when it was that.. thing.

Hope this helps
