遍历多个复选框并获取选定的标题

<form id="myForm">
  <input type="checkbox" id="checkbox1" name="checkbox" value="Checkbox 1">
  <label for="checkbox1">Checkbox 1</label><br>
  <input type="checkbox" id="checkbox2" name="checkbox" value="Checkbox 2">
  <label for="checkbox2">Checkbox 2</label><br>
  <input type="checkbox" id="checkbox3" name="checkbox" value="Checkbox 3">
  <label for="checkbox3">Checkbox 3</label><br>
  <!-- 添加更多复选框 -->
</form>

var checkboxes = document.getElementsByName("checkbox");
var selectedTitles = [];

for (var i = 0; i < checkboxes.length; i++) {
  if (checkboxes[i].checked) {
    var label = document.querySelector('label[for="' + checkboxes[i].id + '"]');
    selectedTitles.push(label.innerHTML);
  }
}

console.log(selectedTitles);
