Autopopulate fields in Service Catalog form

[Brian Sorensen]

Im sure this is simple and i'm just overthinking it...

I have a form that points to specific hardware in the peripheral table (cmdb_ci_peripheral)

I want to do the following

Select Box - user selects the peripheral < this works

Then Autopopulate the following fields

MAC Address

Serial Number

IP Address

Looking at the table view my assumption is that the names are

mac_address , serial_number, ip_address

When I try and script this for onChange I am doing the following - any idea where I missed?

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

if (isLoading || newValue == '') {

return;

}

var user = g_form.getReference('existing_unit_name', populateReqForDetails);

function populateReqForDetails(cmdb_ci_peripheral) {

g_form.setValue('existing_mac_address', cmdb_ci_peripheral.mac_address);

g_form.setValue('existing_serial_number', cmdb_ci_peripheral.serial_number);

g_form.setValue('existing_ip_address', cmdb_ci_peripheral.ip_address);

}

}

Hi Brian,

I suggest you use GlideAJAX since getReference() is not a recommended practice anymore for retrieving data due to their performance impact.

This thread could guide you on how to retrieve the needed data from SN tables using GlideAJAX:

Hope it helps!

Hi, 

Is the field name correctly called in the script i.e., existing_unit_name?

Next - Onchange script based on what field selection the below code is running? did you verify it?

Hi @Brian Sorensen 

Did you try with Auto Populate on variable?
