【问题描述】：

我有一张桌子，在这张桌子上我给<th> 中的复选框，比如<th><input type="checkbox" id="selectedrecord" name="selectedrecord" value="1" />Sr No</th>。目前它给了我选定列的值。现在我想显示和隐藏此列。

以下是我的代码

<form role="form" id="print_loading_sheet" method="POST" enctype="multipart/form-data">

<section class="content">
<div class="row">
 <div class="table-responsive">
   <table id="delivery_checklist_table" class="table table-bordered  table-sm" style=" overflow: auto;">

 <thead>
  <tr>
    <th><input type="checkbox" id="selectedrecord" name="selectedrecord" value="1" />Sr No</th>
    <th><input type="checkbox" id="selectedrecord" name="selectedrecord" value="2" />Bilty Id</th>
    <th><input type="checkbox" id="selectedrecord" name="selectedrecord" value="3" />LR No</th>
    <th><input type="checkbox" id="selectedrecord" name="selectedrecord" value="4" />Consignor Name</th>
    <th><input type="checkbox" id="selectedrecord" name="selectedrecord" value="5" />Consignor GSTIN</th>
    <th><input type="checkbox" id="selectedrecord" name="selectedrecord" value="6" />Consignee Name</th>
    <th><input type="checkbox" id="selectedrecord" name="selectedrecord" value="7" />Consignee GSTIN</th>
 </tr>

  </thead>
  <tbody>

    <?php $counter = 1; ?> 
    <?php foreach($bilties as $bilty):?>

  <tr>
  <td><?php echo $counter;?></td>
  <td><?php echo $bilty->id;?></td>
  <td><?php echo $bilty->lr_no;?></td>
  <td><?php echo $bilty->consignor;?></td>
  <td><?php echo $bilty->consignor_gst_no;?></td>
  <td><?php echo $bilty->consignee;?></td>
  <td><?php echo $bilty->consignee_gst_no;?></td>
 </tr>
     <?php $counter++; ?>
     <?php endforeach; ?>              
</tbody> 
    </table>
   </div>
 </div>

    </section>
      <button id="print" name="print" class="btn btn-block btn-outline-primary fa fa-newspaper-o col-10 offset-1" style="margin-top: 35px; margin-bottom: 25px;" data-clicked="unclicked"> Print </<button type=""></button>> 
  </form>
  </div>

<script>
  $('#print').click(function (event) {
    event.preventDefault();

  var allVals = [];

  $('input[name=selectedrecord]:checked').each(function() {
    allVals.push($(this).val());
  });
    console.log("check Column"+ allVals);
    alert(allVals);
});
</script>

</body> 
</html>

【问题讨论】：

id 必须是 unique ...并且您有 7 个 selectedrecord...

如果您在表格标题中放置复选框，那么这是您的解决方案，然后如何显示和隐藏您需要在表格上方放置复选框的列

function hideshow(){
  var cells=document.getElementById('tab').getElementsByTagName('td'), i=0, c;
  var chb=document.getElementById('chboxes').getElementsByTagName('input');
  while(c=cells[i++]){
    c.style.display=chb[c.cellIndex].checked?'':'none';
  }
}

function setEvent(){
  var chb=document.getElementById('chboxes').getElementsByTagName('input'), i=0, c;
  while(c=chb[i++]){
   if(c.type=='checkbox'){
       c.onclick=function(){
            hideshow()
       }
   }
  }
}
onload=setEvent;

【解决方案2】：

您可以遍历数组以使用eq() 设置 display 属性：

allVals.forEach(function(i){
  $('tr').each(function(){
    $(this).find('td, th').eq(i-1).css('display', 'none');
  });
});

演示：

$('#print').click(function (event) {
  $('td').css('visibility', 'visible');
  event.preventDefault();
  var allVals = [];
  $('input[name=selectedrecord]:checked').each(function() {
    allVals.push($(this).val());
  });
  //console.log("check Column"+ allVals);
  allVals.forEach(function(i){
    $('tr').each(function(){
      $(this).find('td, th').eq(i-1).css('display', 'none');
    });
  });
});

【讨论】：

它只隐藏记录，但我想隐藏孔列并显示在打印页面中
@farhantechno，将th 添加到find().....$(this).find('td, th').eq(i-1).css('visibility', 'hidden');
它的工作，但在打印页面上它需要隐藏列的空间
@farhantechno，试试css('display', 'none');......$(this).find('td, th').eq(i-1).css('display', 'none');

【解决方案3】：

我的解决方案...

const MyTable = document.querySelector('#my-table tbody')

document.querySelectorAll('#my-table thead input[type=checkbox]').forEach(inChk=>
{
  inChk.checked = true
  inChk.addEventListener('change', HeadClick)
})

function HeadClick(e) {
  let Col_ALL = MyTable.querySelectorAll(`td:nth-child(${e.target.value})`)

  if ( e.target.checked  ) Col_ALL.forEach(eTD=>eTD.style.visibility='visible' )
  else                     Col_ALL.forEach(eTD=>eTD.style.visibility='hidden')
}

table { border-collapse: collapse; margin: 1em }
td { border: 1px solid grey; padding: .5em 1em; height: 1em; }

<table id="my-table">
  <thead>
    <tr>
      <td><input type="checkbox" value="1"/></td>
      <td><input type="checkbox" value="2"/></td>
      <td><input type="checkbox" value="3"/></td>
      <td><input type="checkbox" value="4"/></td>
      <td><input type="checkbox" value="5"/></td>
    </tr>
  </thead>
  <tbody>
    <tr><td>0.0</td><td>0.1</td><td>0.2</td><td>0.3</td><td>0.4</td></tr>
    <tr><td>1.0</td><td>1.1</td><td>1.2</td><td>1.3</td><td>1.4</td></tr>
    <tr><td>2.0</td><td>2.1</td><td>2.2</td><td>2.3</td><td>2.4</td></tr>
    <tr><td>3.0</td><td>3.1</td><td>3.2</td><td>3.3</td><td>3.4</td></tr>

试试这个。我已经更新了您的代码，这可能会对您有所帮助。选中时显示列，未选中时隐藏。

它只隐藏我想要带有标题的孔列的数据
我已经编辑了代码，请检查。我想这就是你要考虑的。
id 被问到的问题没有使用，所以我删除了它。
