What Scripting Does ServiceNow Use?
ServiceNow is a powerful platform that offers a wide range of functionalities for managing various aspects of an organization’s operations. One of the key features of ServiceNow is its ability to automate tasks and processes using scripting languages. In this article, we will explore the scripting language used by ServiceNow and understand how it enhances the platform’s capabilities.
The Role of Client Scripts
In ServiceNow, client-side scripts play a crucial role in customizing user interfaces and enhancing form functionalities. Client scripts are executed on the user’s device, typically within the browser environment. They are used to validate form inputs, perform calculations, and create dynamic interactions.
Types of Client Scripts:
1. OnLoad Scripts:
OnLoad scripts are executed when a form is loaded. They allow developers to prepopulate fields, set default values, or perform any necessary setup tasks before the user interacts with the form.
2. onChange Scripts:
onChange scripts trigger whenever a specific field’s value is modified by the user. These scripts are helpful for performing real-time calculations or validations based on user inputs.
3. onSubmit Scripts:
onSubmit scripts are executed when a form is submitted by the user. They can be used to perform final validations, trigger notifications, or initiate backend processes.
The Power of Server-Side Scripting
ServiceNow also utilizes server-side scripting to handle complex business logic and interact with external systems. The server-side scripting language used by ServiceNow is called GlideScript.
GlideScript provides powerful capabilities for querying and manipulating data stored in ServiceNow databases, executing server-side business rules, and integrating with external web services or databases.
- Data Manipulation: GlideScript allows developers to create, read, update, and delete records within ServiceNow databases using simple API calls.
- Business Rules: GlideScript enables developers to define custom business rules that automatically execute when specific conditions are met.
- Ajax Calls: GlideScript provides methods for making asynchronous requests to external APIs, enabling seamless integration with third-party systems.
- Security and Access Control: GlideScript includes built-in security measures to ensure data integrity and enforce access controls based on user roles and permissions.
