To pull information from approval tab using javascript

Hi Pavithra,
                     You can create a Client plugin and run a workitem query to retrieve the item ids first and then retrieve the approver values for each of the individual approval items.

Useful methods for this:

ISaveParameter param = (ISaveParameter) data;          
IAuditable auditable = param.getNewState();                   
                if (auditable instanceof IWorkItem) {                  
                IWorkItem sourceworkItem = (IWorkItem) auditable;               
IApprovals approvals= sourceworkItem.getApprovals();
approval.getApprover()

Thanks.

Hi Pavithra,
                    I am not sure if this can be done using the javascript. But you can do it using Java API. Should be possible using Rest service as well.

Is this required to be run on all existing items (or) for new items?

Thanks.

You can get the approver using the REST API. If you have an existing REST query for a set of work items, ensure that the end of the query URL includes the following display attributes:

|approvals/approver/name
