Javascript Programming Tutorials, Guides & Best Practices

Here is the JavaScript code to achieve this:

// 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();
    });
});

In this example:

• We create a new XMLHttpRequest object and open a GET request to the JSONPlaceholder API (a fake online REST API).
• When the request is successful (status code 200), we parse the JSON data and display it on the page.
