Get customfieldvalue with JS

[Deleted user]

Hello!

Im having abit of issue getting a customfield value for an issue with values that are in the background e.g when there is a transition screen, i want to pull an existing customfield value that was entered in at the create screen visible in the background

I currently can get the value if the field is within the same transition screen, but i cant do this when the field is not in the transition screen:

document.getElementById("customfield_10000").value;

Any guidance?

Many thanks, 

Pon

Hello, 

First you have to get issue key using jira javascript API JIRA.Issue.getissuekey(). Then you can retrieve the value of the required field using Jira REST API /rest/api/2/issue/{issueIdOrKey}. Replace {issueIdOrKey} with the key retrieved by Jira.Issue.Getissuekey().
