The solution involves a combination of JavaScript and jQuery to create a functional calculator with real-time validation and updates, alongside a modal popup for additional information. Here’s how the solution is structured:

Input Validation

  • Functionality: Validates user inputs to ensure they are numeric and handle comma-separated values.
  • Implementation: Utilizes a debounce function to limit the frequency of validation checks, improving performance and responsiveness. Inputs are validated on keyup and blur events.

Data Calculation

  • Functionality: Calculates various metrics based on user input, including manual hours, automated hours, and associated costs.
  • Implementation: Processes the user inputs to compute values and dynamically updates the display elements with formatted results.

Modal Popup

  • Functionality: Toggles the visibility of a modal popup for displaying additional content.
  • Implementation: Uses jQuery to handle click events for opening and closing the modal. Ensures smooth user interaction by applying and removing the `modal-active` class.

Handling Hidden Fields

  • Functionality: Updates hidden form fields with processed values for further use.
  • Implementation: Dynamically retrieves the form’s ID to select and update hidden fields based on user input.


Here is the JavaScript code that achieves these functionalities:
