私は、ユーザーがテーブルの行を編集/保存できるHTMLテーブルを持っています。表の行にある<td>の1つには、ドロップダウンだけが含まれ、他のすべての列と同様に実際のテキストは含まれません。私がsaveを押すたびに、私のAJAXリクエストは<td>を除いてすべてのデータをupdate.phpに送信します。私はAJAXの成功関数のドロップダウンの値を取得していますが、PHPのエラーログを確認すると、ドロップダウンの値を保持する変数checkeredは定義されていません。
私のコードを修正して、checkered変数のwhatsも読み込み、それを私のAJAXリクエストでも送信できるようにするにはどうすればいいですか？
はJavaScript（私の機能の開始後最初の2行は、ドロップダウン選択の値を取得するものです）：
$(document).on("click", "#table .edit", function() {
var $row = $(this).parents('tr');
var checkered = $row.find($(".selected")).val();
var $this = $(this);
$this.closest('tr').find('select').attr("disabled", false);
var tds = $this.closest('tr').find('td').filter(function() {
return $(this).find('.edit').length === 0;
});
if ($this.val() === 'Edit') {
$this.val('Save');
tds.not('.dropdown-select').prop('contenteditable', true);
} else {
var isValid = true;
var errors = '';
var elements = tds;
var dict = {};
elements.each(function (index, element) {
var type = $(this).attr('class');
var value = (element.tagName == 'INPUT') ? $(this).val() : $(this).text();
// ----- Switch statement that provides validation for each table cell -----

この行を 'var checkered = $ row.find（$（" select "））.val（）;'で区切ってはいけません。 – claudio
@claudio私はそれに切り替えると動作しません – Rataiczak24
