javascript - 如何隐藏和显示带有选中复选框的表列

Question

我有一个表，在该表中，我在 <th> 中给出了复选框喜欢<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这一列。

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>

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');
    });
  });
});
