On Change Client Script to auto populate fields

[mgjk]

Hi all,

Greetings. I have created an application called Transfer Tracker.  I wanna auto populate the short description, description field if changed the filed name called Ticket_Number. Ticket_number field is Reference field from Incident Table. Please find the below script. Also find the attached files for the field types which I have created

DescriptionFieldShort DescriptionForm for Transfer TrackerTicketNumber Field

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading || newValue === '') {
return;
}

//Type appropriate comment here, and begin script below

}
var incSD=g_form.getReference('u_ticket_number',populate);
function populate(incSD){
if(incSD.short_description){
g_form.setValue('u_ttshort_description',incSD.short_description);
g_form.setValue('u_tt_description',incSD.description);
}
}

}

Hi,

I suggest that you look at existing onChange Client Scripts for working examples.  Also see:

https://developer.servicenow.com/dev.do#!/reference/api/utah/client/c_GlideFormAPI#r_GlideForm-GetRe...

and in general:

https://developer.servicenow.com/dev.do#!/reference/api/utah/client/c_GlideFormAPI

There are many examples there.

Hi,

It looks like your code is outside of the onChange function.

Please try the following version:

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
  if (isLoading || newValue === '') {
    return;
  }

  var incSD = g_form.getReference('u_ticket_number', populate);

  function populate(incSD) {
    if (incSD && incSD.short_description) {
      g_form.setValue('u_ttshort_description', incSD.short_description);
      g_form.setValue('u_tt_description', incSD.description);
    }
  }
}

Hi Isais,

Thanks a lot for the reply. In Previous assignment group field, its showing sys ID I guess instead of  Group name please find the attachment. 

And the script is given below

function onChange(control, oldValue, newValue, isLoading, isTemplate) {

  if (isLoading || newValue === '') {

    return;

  }

  var incSD = g_form.getReference('u_ticket_number', populate);

  function populate(incSD) {

    if (incSD && incSD.short_description) {

      g_form.setValue('u_ttshort_description', incSD.short_description);

      g_form.setValue('u_tt_description', incSD.description);

g_form.setValue('u_previous_assignment_group', incSD.assignment_group);

    }

  }

Regards..

setValue has an additional parameter to specify a display value

You can try:

g_form.setValue('u_previous_assignment_group', incSD.assignment_group, incSD.assignment_group.getDisplayValue());
