Event listeners for stress and mood tracking events in JavaScript

EventListeners

In today’s fast-paced world, it’s important to prioritize mental health and keep track of our stress levels and moods. With JavaScript, we can easily create event listeners to track these events and capture valuable data. In this article, we’ll explore how to set up event listeners for stress and mood tracking in JavaScript.

Set Up HTML Structure

First, let’s set up our HTML structure. We’ll create a simple form with input fields for stress level and mood. Open your HTML file and add the following code:

<!DOCTYPE html>
<html>
<head>
    <title>Stress and Mood Tracking</title>
</head>
<body>
    <h1>Stress and Mood Tracking</h1>
    <form id="trackingForm">
        <label for="stressLevel">Stress Level:</label>
        <input type="number" id="stressLevel" min="1" max="10"><br>

        <label for="mood">Mood:</label>
        <select id="mood">
            <option value="happy">Happy</option>
            <option value="sad">Sad</option>
            <option value="angry">Angry</option>
            <option value="calm">Calm</option>
        </select><br>

        <button type="submit">Submit</button>
    </form>
</body>
</html>

Implement Event Listeners

Next, let’s add JavaScript code to implement our event listeners. Open your JavaScript file and add the following code:

const trackingForm = document.getElementById('trackingForm');

trackingForm.addEventListener('submit', function(event) {
    event.preventDefault(); // Prevent form submission

    const stressLevel = document.getElementById('stressLevel').value;
    const mood = document.getElementById('mood').value;

    // Process the data or send it to a server for storage/analysis
    console.log(`Stress Level: ${stressLevel}`);
    console.log(`Mood: ${mood}`);

    // Reset the form
    trackingForm.reset();
});

In the above code, we have added an event listener to the form’s submit event. When the user clicks the submit button, the event listener function is triggered. We prevent the form from submitting using event.preventDefault() to keep the data on the page.

Then, we capture the values of the stress level and mood from their respective input fields. You can use these values to post the data to a server for storage or further analysis.

In our example code, we simply log the stress level and mood to the console. However, you can modify this code to suit your specific needs, such as saving the data to a database or performing calculations based on the user’s inputs.

Finally, we reset the form using trackingForm.reset() so that the input fields are cleared after submission.

Conclusion

By setting up event listeners for stress and mood tracking events in JavaScript, you can easily capture and process valuable data. Whether you’re building a mental health tracking app or conducting research, these event listeners provide a solid foundation for collecting and analyzing user inputs. Remember to adjust the code according to your specific requirements and make the most of the captured data.
