如何更新csv文件以记录使用toggleClass jQuery函数实现的用户选择的图像？

<form id="imageForm">
  <img src="image1.jpg" class="toggle-image" data-image-id="1">
  <img src="image2.jpg" class="toggle-image" data-image-id="2">
  <img src="image3.jpg" class="toggle-image" data-image-id="3">
</form>

$(document).ready(function() {
  $('.toggle-image').on('click', function() {
    $(this).toggleClass('selected');
  });
});

function createCSV() {
  var csvContent = "data:text/csv;charset=utf-8,";
  var rows = [];

  $('.selected').each(function() {
    var imageId = $(this).data('image-id');
    var row = [imageId];
    rows.push(row);
  });

  rows.forEach(function(rowArray) {
    var row = rowArray.join(",");
    csvContent += row + "\r\n";
  });

  var encodedURI = encodeURI(csvContent);
  var link = document.createElement("a");
  link.setAttribute("href", encodedURI);
  link.setAttribute("download", "image_selection.csv");
  document.body.appendChild(link);
  link.click();
}

$('#imageForm').on('submit', function(e) {
  e.preventDefault();
  createCSV();
});
