New help on changing the variable label text.

Lisa Goldman — Fri, 14 Mar 2025 00:07:09 GMT

Hello,

I’m using g_form.setLabelOf('Old Phone Number', 'New Phone Number') method to dynamically change the label of a variable. While the label changes successfully on the portal, it doesn't update in the desktop view. Could someone please help?

Thank you

Is there a reason you do not just go to the variable definition and change it there?

Hi @DrewW

Thank you for your suggestion. We also can create two separate variables and hide or display them based on certain conditions. However, we would like to know if there is a way to dynamically change the label text using a client script. If the g_form.setLabelOf method works on the portal, why isn't it functioning in the fulfiller view?

Hi @Lisa Goldman ,

The first parameter of the setLabelOf method is the name of the variable (looks like you are passing the label for the variable)

g_form.setLabelOf('Old Phone Number',/*update this with name of the Variable*/ ,'New Phone Number')

If the issue still persists check for any errors in the browser console and share the screenshot of those errors.

Please mark my answer as helpful/correct if it resolves your query.

I'm assuming you checked to make sure that the client script is set to run on the Item and cat task correct?

Also have you checked the browser console to see if there is an error?

Hi @Chaitanya ILCR

The original post was only an example. Below is the code I used to test it in my PDI. It works fine in the portal without any error messages. However, in the fulfiller view (RITM, TASK), the label did not change.

I'm testing this code in a Multiple Choice variable, when a option is select, the text label should change to 'New Phone', but it did not.

function onChange(control, oldValue, newValue, isLoading) { if (newValue == 'yes') { g_form.setLabelOf('old_phone', 'New Phone'); } else { g_form.setLabelOf('old_phone', 'Old Phone'); } }

Hi @DrewW

The issue I'm encountering is with the Item and Catalog Task in the fulfiller view.

It works perfectly fine in the self-service portal without any errors.

Below are the steps I tested in my PDI. When you have a chance, you can replicate it in your PDI to check if you're experiencing the same issue.

STEP 1 - Create a text variable

STEP 2 - Create a Multiple choice variable with one value "yes"

STEP 3 - onChange Client Script code:

function onChange(control, oldValue, newValue, isLoading) { if (newValue == 'yes') { g_form.setLabelOf('old_phone', 'New Phone'); } else { g_form.setLabelOf('old_phone', 'Old Phone'); } }

Hi @Lisa Goldman ,

Looks like it's not a straightforward solution to set a label for catalog items

https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB0758098

https://servicenowguru.com/ui-scripts-system-ui/modifying-label-form-fields-client-scripts/

I have used these and update the client script as below with isolate script as false

I am also attaching the XML of updated version of client script.

import it and try

but at this point it's easier to create/maintain two separate variables for this as this involves DOM manipulation which is not recommended and might break with future releases.
