我根据PHP中的查询结果创建了一个表格。它是一个可编辑的表，当用户单击save时，我需要遍历表元素并将文本值存储到数组中。作业＃列中的值必须位于开始或结束 每次迭代循环，以便我可以轻松地提取它，然后在我完成时使用它来插入值。
PHP表格创建
<?php
if(isset($_POST['aid'])) {
$aid = $_POST['aid'];
$projects = getProjects($db);
$members = getUserName($db);
try {
$project_info = $db->prepare("

projects.project_name,

}
echo "</table>";
} catch(PDOException $e) {
die($e->getMessage());
}
} else {
echo 'could not load projects table';
}
?>
现在我用来获取这些数据的代码就像这样
的jQuery
$('.projects_editable_content_td, .projects_contentTable td:nth-child(3) a').each(function () {
saveEdits.push($(this).text());
});
// then alert the values using this loop
$.each(saveEdits, function(index, value) {
alert(index + ': ' + value);
});
当循环播放时，我从saveEdits [0]和saveEdits [1]获取Job＃的值，然后我从[select]元素中获取所有[option]值。我知道这是因为我不知何故需要在这个循环中加入“option：selected”。无论如何，我的循环是一团糟，经过几个小时的乱搞，我不能让这个东西工作。
所以，我需要循环遍历每个tr，从tr中的每个td元素中获取文本值，并在每次迭代的开始或结束时存储来自Job＃列的值。循环。
非常感谢任何帮助

如果您为id_cell等特定单元格添加额外的类，则会为您提供每行的第一个单元格内容。
PHP：
while ($row = $project_info->fetch(PDO::FETCH_ASSOC)) {
echo "<tr>";
echo "<td class='content_td id_cell'>" . "<a href='#'>" . $row['id'] . "</a>" . "</td>";
jQuery的：
$(".projects_contentTable tr").each(function(){
$(this).find('.id_cell');
});
如果您想在该单元格中获取您的确切ID，可以执行以下操作：
var id = $(this).find('.id_cell').find('a').text();
但当然，如果这是你想要的，我真的无法得到你的问题！

如果我理解正确，我相信这会起作用，或者至少是非常类似的东西。一次迭代一行，对于每一行，从＆lt;中获取文本。 td＆gt; s缺乏＆lt;选择＆gt; s，然后从选中的＆lt;中获取文本选项＆gt; s。顺便说一句，不要忘记添加＆lt; / select＆gt;在你的PHP中，添加＆lt;并不是一个坏主意。 thead＆gt;和＆lt; tbody＆gt;。欢呼声。
$('tbody tr').each(function() {
$('td:not(:has(select)),option:selected').each(function() {
saveEdits.push($(this).text());
});
});
