Introduction to ServiceNow with JavaScript
ServiceNow is a leading cloud-based platform widely used for IT service management (ITSM), operations management, and business process automation. One of the core strengths of ServiceNow is its extensibility, primarily achieved through JavaScript scripting. JavaScript empowers ServiceNow developers to customize applications, automate workflows, and integrate with other enterprise systems seamlessly.
At Online IT Guru, our ServiceNow with JavaScript course is designed to equip learners with the essential scripting skills needed to harness the full potential of ServiceNow. This course combines theoretical knowledge and real-world practical sessions, helping you master both client-side and server-side scripting using JavaScript.
Why Learn ServiceNow with JavaScript?
JavaScript is the backbone of scripting in ServiceNow. Here’s why integrating ServiceNow Online Training in Hyderabad JavaScript skills into your ServiceNow expertise is a game-changer:
- Customization: Tailor ServiceNow applications to fit unique business requirements by writing custom client and server scripts.
- Automation: Use JavaScript to automate routine tasks such as notifications, approvals, and data validations.

- Enhanced User Experience: Create dynamic forms and responsive user interfaces with client-side JavaScript.
- Career Growth: Demand for ServiceNow developers with strong JavaScript skills continues to grow across industries globally.
What is JavaScript in ServiceNow?
ServiceNow uses JavaScript extensively across its platform:
- Client-Side Scripting: Runs in the user's browser to control UI behavior, form validations, and client-side logic.
- Server-Side Scripting: Runs on the ServiceNow server to manage database operations, business rules, and workflow automation.
The platform offers powerful APIs such as GlideRecord, GlideForm (g_form), and GlideUser that simplify scripting tasks and provide access to ServiceNow's data and services.
Course Overview: ServiceNow with JavaScript Training
Online IT Guru’s ServiceNow with JavaScript course covers comprehensive topics including:
1. JavaScript fundamentals tailored for ServiceNow scripting
This means learning the essential JavaScript concepts—like variables, functions, loops, and objects—but specifically focused on how they apply within the ServiceNow platform. Since ServiceNow uses JavaScript to create custom functionality, it’s important to understand these basics with examples and syntax that match ServiceNow’s environment.
2. Client-side scripting: UI Policies, Client Scripts, and UI Actions
Client-side scripting runs in the user's browser and controls what the user sees and interacts with in real time.
- UI Policies: These are rules that dynamically change the behavior or appearance of forms without coding. For example, making a field mandatory or read-only based on certain conditions.
- Client Scripts: These are custom JavaScript code snippets that run on the client side to handle form validations, field value changes, and other interactions.
- UI Actions: Buttons, links, or context menu items on the user interface that trigger client-side or server-side scripts when clicked.
3. Server-side scripting: Business Rules, Script Includes, and Scheduled Jobs
Server-side scripting runs on the ServiceNow server and handles backend logic, like database operations and business workflows.
- Business Rules: These are scripts that execute when records are inserted, updated, or deleted in the database. They can run before or after these actions to enforce business logic.
- Script Includes: Reusable server-side scripts or functions that can be called from other scripts, making your code modular and maintainable.
- Scheduled Jobs: Automated server-side scripts that run at specified times to perform tasks such as batch updates, cleanup, or report generation.
4. Glide API usage for database interactions and workflow automation
ServiceNow provides a powerful JavaScript API called Glide API that lets developers interact with the platform’s database and workflow engine programmatically.
- For example, GlideRecord is used to query or modify records in tables.
- GlideForm (g_form) and GlideUser (g_user) help manipulate form fields and get information about the logged-in user.
- Using these APIs, developers can automate complex workflows and data processing tasks efficiently.
5. Integration scripting with REST APIs and Web Services
This involves using JavaScript to connect ServiceNow with external systems via web services.
- REST APIs (Representational State Transfer) and SOAP Web Services are common ways to send and receive data between ServiceNow and other applications.
- Integration scripting allows you to create, consume, or customize APIs to enable data exchange, automate workflows across platforms, or extend ServiceNow’s capabilities.
6. Best practices for writing efficient, maintainable scripts
Writing scripts isn’t just about functionality—it’s also about creating clean, readable, and optimized code. Best practices include:
- Using meaningful variable and function names
- Modularizing code with Script Includes
- Avoiding redundant or heavy database queries
- Proper error handling and debugging
- Following ServiceNow’s security guidelines to protect data
7. Real-time projects involving automation and customization
The course includes practical projects where you apply your scripting skills to real-world scenarios. Examples might be automating incident management workflows, customizing service catalogs, or building dynamic dashboards. These projects help solidify your learning and give you experience that employers value.
8. Preparation for ServiceNow Developer Certification with scripting focus
The training also prepares you specifically for the official ServiceNow Developer Certification, emphasizing the scripting aspects of the exam. This includes understanding where and how to use client and server scripts, APIs, and best practices, ensuring you have the knowledge and confidence to pass the certification and boost your career.
