Creating a Dynamic Tooltip Message in Angular Applications

In Angular applications, tooltips are an excellent way to display helpful hints or additional information to users without cluttering the interface. However, what if you need more than just static text in your tooltips? For instance, you might want to:

Show different tooltip messages based on the application's environment (Development or Production).

Display dynamic calculations from fields when users hover over specific controls.

This guide provides a comprehensive guide on how to create dynamic tooltip messages in Angular applications, particularly focusing on conditional displays and real-time calculations.

Understanding the Problem

If your Angular application is running in development mode, you'd want to display tooltips for various controls indicating how values are calculated. However, in production mode, these tooltips should be hidden to maintain a clean user interface.

Moreover, with numerous calculations involved (over 100 static functions) that need corresponding messages, you'll need an efficient way to manage these tooltips without hardcoding each message.

Implementing the Solution

To implement dynamic tooltip messages in Angular, follow these steps:

Step 1: Setup Calculation Logic

We'll start with the logic to perform calculations and set tooltip messages dynamically. Here’s an example of how to set up your Calculations class:

Step 2: Creating the HTML for Tooltip Component

In your component's HTML, you will need to set up both the input field and logic for the tooltip:

Step 3: Linking Tooltip Messages with Form Controls

You have to ensure that your tooltip messages update dynamically based on form value changes. Here’s an example of how your TypeScript file could handle that:

Step 4: Handling the Development and Production Modes

To ensure tooltips only show in development, you could leverage Angular’s environment configurations. Here’s a sample way to implement that check:

Conclusion

By following these steps, you can effectively implement dynamic tooltip messages in your Angular application tailored to show vital information based on different environments. Not only does this approach enhance user understanding, but it also keeps your application clean and user-friendly.

Feel free to adjust the logic in your calculations and tooltip messages as needed, especially as your application scales and requires more fields.

By mastering dynamic tooltips, you're on your way to not only improving the usability of your application but also impressing your users with thoughtful interactions. Happy coding!
