Happy Holidays, Knack community!
As we wrap up the year, I want to share a solution I implemented for a client who needed dynamic feedback for data entry in their application. While Knack has built-in data validation tools, my client wanted a more interactive approach to show users their character limits in real-time.
With the assistance of OpenAI’s ChatGPT, I was able to craft a JavaScript snippet that updates the character count for a notes field with a maximum limit of 200 characters. This solution allows users to see their character count change as they type. If they exceed the character limit, the input field’s background turns red, the text becomes crimson, and the submit button is disabled—providing clear immediate feedback.
As someone who is not a coder, I found the ability to produce useful and functional code using AI to be a major advantage. By asking natural language questions, I could get the code built up in manageable sections, making it accessible even for those with limited coding experience.
If you’re interested in enhancing your app’s user interface with dynamic validation, check out the video for the code snippet. It’s a fantastic way to improve user experience and ensure data is submitted correctly.
I’d love to hear your thoughts and any similar experiences you’ve had!
