Question

我有一个包含多列和多行的表，还有一个编辑按钮。我想制作2列，MR_ID和MR_Name，不可编辑，同时在单击编辑按钮后保持其余列可编辑。我希望远离.not()，因为它会对我的UPDATE功能产生负面影响。我还能以其他方式实现这一目标吗？

表格的HTML / PHP：

<table id="html_master" class="ui-widget ui-widget-content">
<thead>
    <tr class="ui-widget-header">
    <td>ID</td>
    <td>Vendor</td>
    <td>Buyer ID</td>
    <td>POC Name</td>
    <td>POC Email</td>
    <td>POC Phone</td>
    <td>Edit</td>
    </tr>
</thead>
<tbody>


<?php
    /* Foreach loop that brings in information to populate table */
    foreach ($dbh->query($sql) as $rows){
    ?>
    <tr id="<?php echo intval ($rows['MR_ID'])?>">
        <td class="mr_id" id="mr_id-<?php echo intval ($rows['MR_ID'])?>" contenteditable="false"><?php echo intval ($rows['MR_ID'])?></td>
        <td class="mr_name" id="mr_name-<?php echo intval ($rows['MR_ID'])?>" name="field" contenteditable="false"><?php echo $rows['MR_Name']?></td>
        <td class="buyer_id" id="buy_id<?php echo intval ($rows['MR_ID'])?>" contenteditable="false"><?php echo $rows['Buyer_ID']?></td>
        <td class="poc_n" id="poc_n-<?php echo intval ($rows['MR_ID'])?>" contenteditable="false"><?php echo $rows['MR_POC_N']?></td>     
        <td class="poc_e" id="poc_e-<?php echo intval ($rows['MR_ID'])?>" contenteditable="false"><?php echo $rows['MR_POC_E']?></td>
        <td class="poc_p" id="poc_p-<?php echo intval ($rows['MR_ID'])?>" contenteditable="false"><?php echo $rows['MR_POC_P']?></td>
        <td><input type="button" class="edit" name="edit" value="Edit">
    </tr>
 <?php
  }
 ?>
</tbody>
</table>

JavaScript的：

// ----- Edit Row -----

$(document).on("click", "#html_master .edit", function () {
  var $this = $(this);
  var tds = $this.closest('tr').find('td').filter(function () {
    return $(this).find('.edit').length === 0;
  });
  if ($this.val() === 'Edit') {
    $this.val('Save');
   if($this.id != '.mr_id'){
        tds.prop('contenteditable', true);
   }
  } else {
    var isValid = true;
    var errors = '';
    $('#myDialogBox').empty();
    var elements = tds;
    if (tds.find('input').length > 0) {
      elements = tds.find('input');
    }
    var dict = {}; 
    elements.each(function (index, element) {
      var type = $(this).attr('class');
      var value = (element.tagName == 'INPUT') ? $(this).val() : $(this).text();
      console.log(type);
      // ----- Switch statement that provides validation for each table cell -----

您可以创建此css类并使用jquery在正确的位置添加它

.disable_td{
     background-color: #ddd;
     cursor: not-allowed;
}

或者如果你想隐藏它，请使用

 .disable_td{
         display:none;
    }

之后

位于函数顶部

$(document).on("click", "#html_master .edit", function () {
  var $this = $(this);

添加

$( ".mr_id" ).addClass( "mr_id disable_td" );
$( ".mr_name" ).addClass( "mr_name disable_td" );

在保持其他人可编辑的同时使列不可编辑
