How to access workflow scratchpad variables from client script?

[#1]

Has anyone done this? Thanks in advance.

I have done this and it works great.

In my workflow, I am assigning the value of approval_date to workflow scratchpad variable
var approval_date = sysapproval.u_approved_on.getGlideObject().getNumericValue();
workflow.scratchpad.approval_date = approval_date;

You need to create a "display" business rule to access your workflow scratchpad variable
http://wiki.service-now.com/index.php?title=Business_Rules#Display_Business_Rules

var workflow = new Workflow();
var context = workflow.getContexts(current);
if (context.next()) {
g_scratchpad.approvalDate = context.scratchpad.approval_date;
}

Then you can access the "g_scratchpad.approvalDate" in your client script.

Thanks,
Rajini

I am having trouble coming up with use cases for this. Anything you would want on the form and in the workflow to me seems like a reasonable field addition.

Can anyone provide some examples of how they would use this? I have used the scratchpad to story sys_id's for records generated from another workflow but cannot come up with a specific use case for sharing between g_form/workflow scratchpads.

Either way, Rajini thanks for posting an update on how to do this. Great reference for others!
