我有一个表，我正在根据PHP. 这是一个可编辑的表格，当用户点击保存时，我需要遍历表格元素并将文本值存储到一个数组中。Job# 列中的值必须位于循环的每次迭代的开始或结束，以便我可以轻松提取它，然后在完成时使用它插入值。

PHP 表创建

<?php    

if(isset($_POST['aid'])) {  
    $aid = $_POST['aid'];
    $projects = getProjects($db);
    $members = getUserName($db);            
    try {
        $project_info = $db->prepare("
            SELECT  projects.id,
                    projects.project_name,

                echo "<td class='content_td'>" . $row['pm_perc'] . "</td>";
                echo "<td class='projects_editable_content_td'>" . 
                    "<input type='checkbox' id='table_edit_project_audited'>";
                echo "</td>";               
                echo "</tr>";               
            }
            echo "</table>";                
    } catch(PDOException $e) {
        die($e->getMessage());
    }   
} else {    
    echo 'could not load projects table';
}

?>

现在我目前用来获取这些数据的代码看起来像这样

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); 
});

当这个循环通过时，我在 saveEdits[0] 和 saveEdits[1] 上从 Job# 获取值，然后我从 [select] 元素中获取所有 [option] 值。我知道这是因为我需要以某种方式将“option:selected”合并到这个循环中。无论如何，我的循环是一团糟，在搞砸了几个小时后，我无法让这个东西正常工作。

再次，我需要遍历每个 tr，从 tr 内的每个 td 元素中获取文本值，并在循环的每次迭代开始或结束时存储来自 Job# 列的值。

非常感谢任何帮助

如果您为特定单元格添加一个额外的类，这将为您提供每一行的第一个单元格内容，例如id_cell.

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：

$(".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();

但是，当然，如果这是您想要的，因为我真的无法回答您的问题！

如果我理解正确，我相信这会奏效，或者至少非常类似。逐行迭代，对于每一行，从 <td>s 中获取缺少 <select>s 的文本，并从选中的<option>s 中获取文本。对了，别忘了在你的PHP中添加</select>，添加<thead>和<tbody>也不错。干杯。

$('tbody tr').each(function() {
    $('td:not(:has(select)),option:selected').each(function() {
        saveEdits.push($(this).text());
    });
});
