🌟Unleash the Power of Client Scripting in ServiceNow !

Client Scripts are JavaScript snippets that run directly in the browser, giving you full control over ServiceNow forms—no server lag, just pure dynamic power.

Here’s what you’ll master in this presentation:

⚙️Client Script Types

→ onLoad, onChange, onSubmit, onCellEdit with real examples

📘g_form Methods

→ setValue(), setReadOnly(), showFieldMsg(), addInfoMessage(), and more

👤g_user Methods

→ Retrieve user info, roles, and login state using hasRole(), fullName, isLoggedIn()

📂Core Tables Behind the Scenes

→ sys_script_client, sys_ui_element, sys_dictionary, sys_script_include

💡Real-World Use Cases

→ Incident, Change, HR, and Custom Apps — from auto-assigning fields to dynamic validations

Whether you’re a Developer or Admin, this is your complete client-side scripting guide.

Is this a question or an information article?

If this is for information then I believe similar or same information is already available on docs, youtube etc.

Any specific reason to share this?

Yes, it's purely for informational purposes.

You're right — similar content is already available on docs and YouTube. But I’ve tried to explain it in a simple and easy-to-understand way, just to share and help others who may prefer a quick overview.
