All You Need to Know About ServiceNow Development

Explore the ServiceNow user interface, including the banner, navigation pane, and content area, plus top-bar tools like profile, search, and settings for theme personalization.

Discover how glide record queries are built and executed in ServiceNow. Apply addQuery filters and the dot query to retrieve and process active incidents, then practice in your developer instance.

Create and update incident records with glide record, covering CRUD operations, setting reference fields via sys_id or display values, and capturing the new record's sys_id and number.

Explore how glide record secure enforces ACLs and access controls, ensuring only authorized users can create, read, update, or delete records, unlike plain glide record.

Explore essential GlideRecord methods in ServiceNow, including new record, insert, update, delete, and delete multiple. Learn to use add query, addEncodedQuery, getEncodedQuery, getRowCount, hasNext, next, orderBy, and orderByDescending.

Explore the current object, a server-side glide record for a single incident, to access and update fields like short_description, user_name, or email_ID within business rules, UI actions, and workflows.

Discover how the current object powers server-side ui actions on incident records, printing data with gs.addInfoMessage and updating fields via current.update.

Learn how to use the current object in ServiceNow workflows to set and fetch values, avoid current.update, and rely on automatic updates in UI actions and workflows.

Explore the differences between glide system (gs) and glide record (gr): gs is preinvoked and provides user details, session and time, while gr queries tables and records and requires invocation.

We explore glide system time and date methods, including gs.now and gs.nowDateTime, and profile time zone settings. We also cover lastWeek, hoursAgo, dateDiff, BeginningOfToday, addInfoMessage, addErrorMessage, logs, eventQueues, and properties.

This lecture demonstrates an onChange client script that auto populates the incident assignment group from the selected configuration item using g_form.getReference and cmdb_ci details.

Explore Glide user, a client side object that exposes the logged in user's id, username, roles, and other details, accessible via g_user in client scripts.

Explore the Glide user object properties and methods, including g_user.firstName, lastName, userID, username, and getFullName, and learn how to check roles with hasRole and hasRoles in client and server contexts.

Discover how glide ajax enables client scripts to call server side code via script includes, returning an xml response, with synchronous and asynchronous call differences.

Create a Glide Ajax script include, name it, and enable client callable true. Implement function call me returning 'You sent' and the parameter, and note async equals sync.

Learn the structure of a client script with GlideAjax: define the script include, pass parameters, set sysparm_name, and use synchronous getXML or asynchronous calls, optionally using ga.getAnswer.

Shows how to build a Glide Ajax call between a client script and a script include TestAJAX on an incident form, passing parameters and updating the description with the response.

Explore debugging in ServiceNow, uncovering why we need it and examining server side and client side debugging.

Learn client side debugging in service now using alerts, console logs, and the JavaScript executor to test onchange incident scripts, fetch assignment group details, and populate the short description.
