Javascript for Variables in processes

In a process, you can use a variable to pull data from the Service Catalog into your process. The text below gives examples on different data types.

With the new code update (Feb 2023) it is possible to update a variable using javascript.

This allows to refresh the data every time the variable is used in the process.

This document shows some examples, as the needed JS is different per type of data.

Where to place the JS

When editing a process, on the first tab, go to ‘Variables’.

- Select ‘JavaScript’ in the dropdown

- Check the box ‘ServiceCatalogInterface’

- Enter the JS in the box for the default value

Different types of JS

In yellow: the internal label if the field in the SC

In green : the GUID of the service, in this example, it comes from an action form.

Retrieving a plain value

var serviceparts = JSON.parse(ServiceCatalogInterface.getServiceParts(#REPLACE-FORMFIELD-serviceguid#, ["radiology_clinical_report"]));

if (serviceparts.length) return serviceparts[0].value;

return "";

Retrieving the full name of a custom actor

The JS below is long, as it covers all possible types of custom actor. To retrieve the email, see the next chapter.

var servicesummary = JSON.parse(ServiceCatalogInterface.getServiceSummary(#REPLACE-FORMFIELD-serviceguid#));

if (servicesummary && servicesummary.customactors && servicesummary.customactors.length) {

var customactors = servicesummary.customactors.filter(function (ca) { return ca.internalname === "CRA"; });

if (customactors.length) {

var customactor = customactors[0];

if (customactor.typename === "Single_person") {

//value is single object

if (customactor.value) {

return customactor.value.firstname + ' ' + customactor.value.lastname;

}

} else if (customactor.typename === "Single_persongroup") {

//value is single object

if (customactor.value) {

return customactor.value.name;

}

} else if (customactor.typename === "Multiple_persons") {

//value is array

if (customactor.value) {

return customactor.value.map(function (person) { return person.firstname + ' ' + person.lastname }).join(", ");

}

} else if (customactor.typename === "Multiple_persongroups") {

//value is array

if (customactor.value) {

return customactor.value.map(function (persongroup) { return persongroup.name }).join(", ");

}

}

}

}

return "";

Retrieving the email address of a custom actor

var servicesummary = JSON.parse(ServiceCatalogInterface.getServiceSummary(#REPLACE-VARIABLE-1067-ServiceGUID#));

if (servicesummary && servicesummary.customactors && servicesummary.customactors.length) { var customactors = servicesummary.customactors.filter(function (ca) { return ca.internalname === "Head_of_department"; });

if (customactors.length) { var customactor = customactors[0];

if (customactor.typename === "Single_person") { //value is single object if (customactor.value) { return customactor.value.email; } }

else

if (customactor.typename === "Single_persongroup") { //value is single object if (customactor.value) { return customactor.value.email; } }

else

if (customactor.typename === "Multiple_persons") { //value is array if (customactor.value) { return customactor.value.map(function (person) { return person.email }).join(", "); } }

else

if (customactor.typename === "Multiple_persongroups") { //value is array if (customactor.value) { return customactor.value.map(function (persongroup) { return persongroup.email }).join(", "); } } } } return "";

Retrieving a date in a readeable format

var serviceparts = JSON.parse(ServiceCatalogInterface.getServiceParts(#REPLACE-FORMFIELD-serviceguid#, ["Geplande_einddatum "]));

if (serviceparts.length && serviceparts[0].value) return CommonInterface.utcDateToString(new Date(serviceparts[0].value), "dd/MM/yyyy");

return "";

Retrieving data from a multiselect field

var serviceparts = JSON.parse(ServiceCatalogInterface.getServiceParts(#REPLACE-FORMFIELD-serviceguid#, ["locaties"]));

if (serviceparts.length && serviceparts[0].value) return serviceparts[0].value.join(", ");

return "";

Retrieving ‘yes’ from a Yes/No-field

var serviceparts = JSON.parse(ServiceCatalogInterface.getServiceParts(#REPLACE-FORMFIELD-serviceguid#, ["site_initiation_visit_is_required"]));

if (serviceparts.length && (serviceparts[0].value === true || serviceparts[0].value === false)) return serviceparts[0].value ? "Yes" : "No";

return "";

Retrieve the Phase

var service = JSON.parse(ServiceCatalogInterface.getServiceOverview(#REPLACE-VARIABLE-1682-ServiceGUID#)); return service && service.phase ? service.phase.name : ""

Retrieve the Technical Approvers Person Groups

var service = JSON.parse(ServiceCatalogInterface.getServiceSummary(#REPLACE-VARIABLE-1682-ServiceGUID#, { LoadRelations: false })); return service.technicalapprovalpersongroups ? service.technicalapprovalpersongroups.map(function (grp) { return grp.email; }).filter(function (mail) { return !!mail; }).join("||") : "";
