Creating a Countdown Timer with JavaScript

  • Basic knowledge of HTML, CSS, and JavaScript.
  • A text editor to write the code.
  • A browser to view the output.

We will create a countdown timer that counts down to the 20th of the next month. If the current date is the 20th or later, it will count down to the 20th of the month after next. The countdown will stop once the deadline is reached.

Exporting Table Row Data to CSV in JavaScript 

// Select all export buttons
const exportButtons = document.querySelectorAll('.export-btn');

// Add event listener to each export button
exportButtons.forEach(button => {
    button.addEventListener('click', () => {
        // Get the parent row of the clicked button
        const row = button.closest('tr');

        // Get all cells in the row except the last one (which contains the export button)
        const cells = Array.from(row.querySelectorAll('td'));
        cells.pop(); // Remove the last cell (the button cell)

        // Extract the text content of each cell and wrap them in double quotes (CSV format)
        const cellValues = cells.map(cell => `"${cell.textContent}"`);

        // Create the CSV data by joining cell values with commas
        const csvData = cellValues.join(',');

        // Create a temporary anchor element for the download
        const anchor = document.createElement('a');
        anchor.href = 'data:text/csv;charset=utf-8,' + encodeURIComponent(csvData);
        anchor.download = 'row_data.csv';

        // Programmatically click the anchor to trigger the download
        anchor.click();
    });
});
  • querySelectorAll('.export-btn'): Selects all elements with the class export-btn, i.e., the export buttons.
  • closest('tr'): This retrieves the closest table row (<tr>) that contains the clicked button.
  • querySelectorAll('td'): Retrieves all the <td> cells in the row.
  • Array.from(): Converts the list of cells into an array, which allows us to manipulate it easily.
  • cells.pop(): Removes the last cell (the one containing the export button), as we don’t want it in the CSV.
  • textContent: Extracts the text content from each cell.
  • encodeURIComponent(): Encodes the CSV string, making it safe for use in a URL.
  • anchor.download: Specifies the filename for the CSV file (in this case, row_data.csv).
  • anchor.click(): Programmatically triggers a click on the anchor element, which starts the download.
