Scripting and Advanced Development in the Servicenow 2026

Learn essential array methods in JavaScript, including length, toString, join, and split, and manipulations with slice, splice, push, pop, unshift, and shift, while handling numbers, strings, and objects.

Explore JavaScript objects and methods: define objects with properties and keys, access nested data via dot notation and arrays, and convert between objects and strings using JSON.stringify and JSON.parse.

Explore JavaScript conditions, including if, else if, switch, and the ternary operator, with emphasis on truthy and falsy values, nested conditions, and practical examples.

Explore JavaScript loops—for, while, do-while, for in, and for each—to iterate strings and arrays, print values, control flow with break and continue, and perform split-based parsing.

Create reusable JavaScript functions with the function keyword, parameters, and return values to perform tasks like adding, subtracting, and validating emails, then reuse with loops and arrays.

Learn JavaScript basics from data types and variables to operators, conditionals, loops, and functions, and explore client and server side APIs in ServiceNow.

Explore ServiceNow architecture by examining the 6000-table MySQL database, learn how incident, user, and group data form records, and understand custom tables labeled with you underscore.

Design and implement ServiceNow forms by creating tables, auto-number fields, and diverse field types (reference, string, date/time, choice, boolean) and arrange them in multi-column layouts for incident forms.

Learn to organize ServiceNow forms by adding sections and creating multiple views, such as American, Germany, Paris, and Australia, to tailor fields for different users.

Explore views and view rules in ServiceNow by building a demo incident form with multiple views (default, star, customer, consumer, manager) and implementing location-based view rules to tailor presentation.

Explore dictionary properties in ServiceNow to enforce mandatory and read-only fields, set default values, and implement dependent and calculated values via the current object for display names.

Learn how to configure dictionary properties in ServiceNow, including mandatory, read-only, default and calculated values, dependent values, and choice lists. Understand reference qualifiers and attributes to customize field behavior.

Learn to design process flows on shipping case forms with state-based steps from new to canceled, and create employee-friendly application menus with direct form access and URL arguments.

Learn how shipping case task extends the task table in ServiceNow, inheriting fields and using dictionary overrides to customize mandatory and read-only properties for the child form.

Explore data lookup rules in ServiceNow, including priority and assignment group rules, using source and matcher tables, and defining lookup rules and definitions to auto-populate fields.

Learn how to open shipping case forms and use save, submit, update, and insert actions. Apply table filters in ServiceNow, including state, assignment, and null checks.

Configure ServiceNow UI policies to make fields mandatory, read-only, or hidden based on conditions. Use onload and onchange, and reverse logic, for forms like shipping case.

Master UI policies in ServiceNow to dynamically make fields mandatory, read-only, or visible, control related lists, and enforce state-based rules like resolution details for resolved or on hold reasons.

Learn how data policies in ServiceNow enforce mandatory fields across all data sources, including forms, external systems, scripts, and Excel, ensuring consistent data validation and integrity.

Learn how to use update sets to move development across dev, test, and production environments in ServiceNow, including creation, export, import, merging, and best practices for multi-user teams.

Explore the client side versus server side in ServiceNow, focusing on the glide user client side API to access current user info and roles.

Master glide form api, a client side api to modify forms, using g underscore form to show messages, set values, enforce mandatory, read-only, hide fields, and control sections.

Learn advanced glide form techniques in ServiceNow, using client-side API to show or hide fields and related lists, set and get values, manage options and references, and control attachments.

Learn to build ServiceNow client scripts using JavaScript with glide user and glide form. Master onload, onchange, onsubmit, unload, and on cell edit, including onchange parameters and templates.

Explore onload client scripts in ServiceNow, including role-based field visibility, view-specific behavior, related lists, attachment controls, and asynchronous data population using g_form, g_user, and callback functions.

Explore on change client scripts and onload client scripts to auto populate fields, dynamic defaults, and form state updates, compare with UI policies, and learn execution order and debugging.

Learn to perform create, read, update, and delete operations in ServiceNow using GlideRecord, a server-side API, with scripts for user, group, and other tables.

Learn GlideAjax and on-change client scripts to call server-side script includes, compare get reference and GlideAjax, and implement asynchronous data retrieval for color and configuration items.

Explore GlideAjax as a client-side API to execute server-side scripts, fetch incident, problem, and change data, and populate related fields automatically with string, array, or object responses.

Explore onsubmit client scripts in ServiceNow, enforcing required fields when the state is in progress, preventing submission with return false, handling field messages and attachments, and using Glide Ajax.

Discover client script use cases in ServiceNow, including on-change scripts that auto-populate change request and requested item fields using glide ajax and script includes, plus synchronous versus asynchronous considerations.

Learn how on cell edit client scripts work on lists, use confirm prompts to approve changes, and fetch email, location, and department for the selected color with script includes.

Discover how ui actions function as clickable buttons that run on client and server sides, appearing on forms and lists, and use glide record to create incidents from form values.

Learn to implement ServiceNow ui actions that create incident records from a shipping case form using GlideRecord, update incident references, and conditionally render actions to enforce single or multiple incidents.

Learn to drive ServiceNow UI actions to change problem states via shipping case and problem management, updating the database on the server for in progress, on hold, resolved, and closed.

Learn how client-side UI actions use JavaScript and client-side APIs to validate fields like assigned to, control form submission, and delegate to server-side scripts to update status.

Create and call UI pages in ServiceNow to pop up a client-side assigned-to picker, then update records via glide Ajax using glide dialog window or glide modal.

Learn to build ServiceNow UI pages with HTML and client-side logic, validate and submit resolution data via Ajax, and open incident forms in a glide modal form for seamless updates.

Explore how UI macros extend ServiceNow forms by adding radio buttons, logos, and URLs using formatters, onload scripts, and dictionary integration to display on existing records.
