Hi,

UI scripts provide a way to group client-side JavaScript into a reusable content, similar to how script includes store server-side JavaScript. Administrators can create UI scripts and run them from client scripts and other client-side script objects and from HTML code as a reusable component.

You can get more details in here: https://docs.servicenow.com/bundle/madrid-application-development/page/script/client-scripts/concept/c_UIScripts.html

Thanks!

Hi,

UI scripts

UI scripts provide a way to package client-side JavaScript into a reusable form, similar to how script includes store server-side JavaScript. Administrators can create UI scripts and run them from client scripts and other client-side script objects and from HTML code.

Global UI scripts

You can create a UI script and designate it as global, which makes the script available on any form in the system. You cannot create a global UI script in a scoped application.

You can mark a UI script as Global to make it available on any form in the system. For example, you can create a UI script that has a function helloWorld(), and has the Global field checked:

function helloWorld() {
  alert('Hi');
}

After you create this global UI script, you can call the helloWorld() function from any client script or UI policy you write.

Create a UI script

Create a UI script to define reusable client-side JavaScript code.

To create UI scripts, navigate to System UI > UI Scripts and create or edit a record (see table for field descriptions).

UI scripts

Field	Description
Script Name	Name of the UI script. Ensure the name is unique on your system.
API Name	The API name of the UI script, including the scope and script name (for example, x_custom_app.HelloWorld).
Application	Application that contains the UI script.
Active	Indicator of whether the UI script is active. Only active UI scripts can run.
Global	Indicator of whether the script loads on every page in the system. Note: Use caution when creating global UI scripts because they can impact performance. You cannot create a global UI script in a scoped application.
