Weather

• The HTML structure consists of a container with a search box and a weather card to display the weather information.

• The CSS styles define the appearance and layout of the elements.

• The JavaScript code handles the API request, fetches the weather data, and displays it on the screen.

  • The getWeather() function is called when the "Search" button is clicked.

    • It retrieves the user input from the search box and constructs the API URL with the city name and API key.

    • It performs a fetch request to the API, receives the response, and processes the data.

    • If the response contains an error code (404), it calls displayErrorMessage() to show a message indicating that the city was not found. Otherwise, it calls displayWeatherData() to display the weather information.

  • The displayWeatherData(data) function receives the weather data and updates the weather card with the relevant information.

    • It extracts the city name, temperature, description, and icon code from the data.

    • It creates HTML elements dynamically and populates them with the weather information.

    • It appends the elements to the weather card.

  • The displayErrorMessage(message) function receives an error message and displays it in the weather card.

Note: To use the OpenWeatherMap API in this example, you need to sign up for an API key at OpenWeatherMap. Replace 'YOUR_API_KEY' in the JavaScript code with your actual API key.

When you open the HTML file in a web browser, you'll see the weather application. Enter a city name, click "Search," and the program will fetch and display the weather data for that city. The weather card will show the city name, temperature, description, and a weather icon representing the current weather condition. If there's an error, such as a city not found or an API request failure, an appropriate error message will be displayed.
