by ADMIN 34 views

Overview

In today's digital landscape, tracking user interactions is crucial for understanding user behavior and making data-driven decisions. A counter service that displays the total number of times a button is clicked or pressed can be a valuable tool for businesses and organizations. In this article, we will explore the implementation of a counter service that meets the requirements outlined in the provided specification.

Details and Assumptions

As outlined in the specification, the counter service should have the following features:

  • A label that displays the total counter
  • The counter should be displayed when the page is loaded or reloaded

Acceptance Criteria

To ensure that the counter service meets the requirements, the following acceptance criteria should be met:

Given when I am on the web page
When the page is loaded or reloaded
Then a total tally counter is displayed

Implementation

To implement the counter service, we will use a combination of HTML, CSS, and JavaScript. Here is a step-by-step guide to implementing the counter service:

Step 1: Create the HTML Structure

First, we need to create the HTML structure for the counter service. We will create a <div> element with an ID of "counter" to hold the counter label.

<div id="counter"></div>

Step 2: Add CSS Styles

Next, we need to add CSS styles to display the counter label. We will use the display property to display the label as a block element.

#counter {
  display: block;
  font-size: 24px;
  font-weight: bold;
}

Step 3: Add JavaScript Code

Now, we need to add JavaScript code to update the counter label when the page is loaded or reloaded. We will use the window.addEventListener method to listen for the load event.

window.addEventListener('load', function() {
  // Initialize the counter to 0
  let counter = 0;
  
  // Get the counter label element
  const counterLabel = document.getElementById('counter');
  
  // Update the counter label
  counterLabel.textContent = counter;
  
  // Add an event listener to the button to increment the counter
  const button = document.getElementById('button');
  button.addEventListener('click', function() {
    counter++;
    counterLabel.textContent = counter;
  });
});

Step 4: Add the Button Element

Finally, we need to add the button element that will trigger the counter to increment.

<button id="button">Click me!</button>

Example Use Case

To demonstrate the counter service, let's create a simple web page that displays the counter label and a button to increment the counter.

<!DOCTYPE html>
<html>
<head>
  <title>Counter Service</title>
  <style>
    #counter {
      display: block;
      font-size: 24px;
      font-weight: bold;
    }
  </style>
</head>
<body>
  <div id="counter"></div>
  <button id="button">Click me!</button>
  <script>
    window.addEventListener('load', function() {
      let counter = 0;
      const counterLabel = document.getElementById('counter');
      counterLabel.textContent = counter;
      const button = document.getElementById('button');
      button.addEventListener('click', function() {
        counter++;
        counterLabel.textContent = counter;
      });
    });
  </script>
</body>
</html>
