php

  • 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.
