What Is Active Scripting?


Scott Campbell

Active scripting is a powerful feature in web development that allows websites to interact with users and perform dynamic actions. It enables the execution of scripts written in languages like JavaScript, VBScript, and JScript. These scripts can be embedded directly into HTML documents or referenced externally.

What Is Active Scripting Used For?

Active scripting provides a wide range of functionalities to enhance user experience on websites. Some common uses include:

  • Form Validation: Active scripting can be used to validate user inputs in web forms, ensuring that the data entered is correct and complete.
  • Dynamic Content: By using active scripting, developers can update content on a webpage without requiring a full page reload.

    This allows for more interactive and responsive websites.

  • Event Handling: Active scripting enables developers to respond to user actions such as button clicks, mouse movements, and keyboard inputs. This allows for the creation of interactive elements and user-friendly interfaces.

Different Types of Active Scripting Languages

Active scripting supports multiple languages, each with its own syntax and capabilities. Some commonly used languages include:


JavaScript, also known as ECMAScript, is the most widely used active scripting language. It is supported by all modern web browsers and provides powerful capabilities for manipulating HTML elements, handling events, making AJAX requests, and more.


VBScript, short for Visual Basic Scripting Edition, is primarily used on Windows-based systems. It shares similarities with Visual Basic programming language and can be used for tasks like file manipulation, system administration, and Windows-specific operations.


JScript is Microsoft’s implementation of the ECMAScript standard. It is similar to JavaScript but has some differences in syntax and capabilities. JScript is primarily used in Microsoft technologies like Internet Explorer and Active Server Pages (ASP).

Enabling Active Scripting in Web Browsers

To ensure active scripting works correctly on a user’s browser, it needs to be enabled. However, it’s important to note that active scripting poses potential security risks if not used carefully.

To enable active scripting in different browsers:

  • Internet Explorer: Go to ‘Tools’ -> ‘Internet Options’ -> ‘Security’ tab -> Select the appropriate zone (Internet, Local intranet, Trusted sites, or Restricted sites) -> Click on the ‘Custom level’ button -> Scroll down to ‘Scripting’ section and enable ‘Active Scripting’.
  • Firefox: Type ‘about:config’ in the address bar -> Search for ‘javascript.enabled’ preference -> Set it to ‘true’.
  • Chrome: Click on the three-dot menu icon -> Go to ‘Settings’ -> Click on ‘Privacy and security’ from the left menu -> Select ‘Site settings’ -> Scroll down to ‘Permissions’ section and click on ‘JavaScript’. Enable JavaScript for all sites or specific sites as required.

It’s important for developers to consider browser compatibility when using active scripting. While JavaScript is widely supported across browsers, other languages like VBScript may have limited support outside of Windows-based systems.

In Conclusion

Active scripting is a powerful feature that allows websites to enhance user interactivity and provide dynamic content. With languages like JavaScript, VBScript, and JScript, developers can create engaging and responsive web applications. However, it’s important to use active scripting judiciously and consider browser compatibility and security implications.
