Exporting Table Row Data to CSV in JavaScript
Here’s a complete example of the HTML and JavaScript code together:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Export Table Row to CSV</title>
</head>
<body>
<table>
<tr>
<td>Apple</td>
<td>Banana</td>
<td>Cherry</td>
<td><a class="export-btn">Export</a></td>
</tr>
<tr>
<td>Dog</td>
<td>Cat</td>
<td>Bird</td>
<td><a class="export-btn">Export</a></td>
</tr>
</table>
<script>
// 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();
});
});
</script>
