javascript - 在动态输入字段中显示多行

标签 javascript php jquery html

我正在尝试创建一个动态的编辑表单。用户可以添加更多行或删除行。

我的php.ini没有问题。问题出在我的 Jquery 中。

这是我的 HTML

  <?php
                $attributes = array('class' => 'form-horizontal', 'id' => '');
                echo form_open_multipart($controller.'/save',$attributes);
                ?>

               <div class="form-group">
                    <label class="col-sm-3 control-label">Attendance Date </label>
                    <div class="col-sm-7">
                    <div class="input-group">
                      <div class="input-group-addon">
                        <i class="fa fa-calendar"></i>
                      </div>
                      <input id="datetimepicker_mask" type="text" value="<?=inggris_date($master->startdate)?>" readonly name="attendance_date" class="form-control"/>
                    </div>
                    </div>
                    </div> 


                     <div class="form-group">
                        <label class="col-sm-3 control-label">Keterangan</label>
                        <div class="col-sm-5">
                        <textarea class="form-control" required name="keterangan"><?=$master->keterangan;?></textarea>
                        </div>
                    </div>

                   <table width="100%" id="example1" class="table table-bordered table-striped">
                        <tr> <td>
                                No.
                            </td>
                            <td> Nama Lengkap </td> 

                        </tr>

                       <?php 
                       $x = 0;
                       foreach($detail as $det) { 
                       $x++;
                       ?> 
                        <tr id = 'ke<?=$x;?>'> 
                            <td> <?=$x;?> </td>
                            <td> 
                                <select name="nip[]" class="form-control select2">
                                <option>   -- </option>
                                <?php foreach($emp as $orang){ ?>
                               <option <?php if($det->nip == $orang->Nip) echo "selected"; ?> value="<?=$orang->Nip;?>"> [<?=$orang->Nip;?>] - [<?=$orang->FullName;?>] </option>
                                <?php } ?>
                                 </select> 
                           </td>
                        </tr>
                        <?php } ?>


                    </table>
                         <div><a id="add_row" class="btn btn-success pull-left">Tambah Baris Baru</a>&nbsp;&nbsp;&nbsp;<a id="delete_row" class="pull-left btn btn-danger">Hapus Baris</a></div>
                             <br>
                             <br>

              <div class="box-footer">
                    <button type="reset" class="btn btn-default">Reset</button>
                    <button type="submit" class="btn btn-info pull-right">Save</button>
                  </div><!-- /.box-footer -->
                </form>

这是我的 Jquery

      <?php $totaldata  = count($detail); echo "Total data = ".$totaldata; ?>
<script type="text/javascript">     
$(document).ready(function(){

      var i=<?=$totaldata;?>;
     $("#add_row").click(function(){
       $('#ke'+i).html("<td>"+ (i+1)  +"</td><td><select name='nip[]' class='form-control'>"+
                                "<option> -- </option>"+
                                <?php foreach($emp as $orang){ ?>
                                 "<option value='<?=$orang->Nip;?>'> [<?=$orang->Nip;?>] - [<?=$orang->FullName;?>] </option>"+
                                <?php } ?>
                                 "</select> </td>");
      $('#example1').append('<tr id="ke'+(i+1)+'"></tr>');
      i++; 
  });
     $("#delete_row").click(function(){
         if(i>1){
         $("#ke"+(i-1)).html('');
         i--;
         }
     });


});
</script>

所以，这是我第一次加载页面时遇到的问题。 View 是这样的

enter image description here

然后，当我点击 Tambah Baris Baru

时会发生什么

enter image description here

第二行消失了。而且编号错误。

这就是当我点击Hapus Baris时发生的事情

enter image description here

它按预期工作。但编号是错误的。

那么，我该如何解决这个问题呢？对不起，我的英语不好。谢谢。

最佳答案

正如您所怀疑的那样，问题在于 i 的值。在第一次执行期间，i 的值为 2，它已经具有第二行，它会用新添加的行覆盖它(slno 3)。

$(document).ready(function() {

  var i = 2;
  $("#add_row").click(function() {
    i++;
    var $tr = $('<tr id="ke' + i + '"></tr>').appendTo('#example1');

    $tr.html("<td>" + (i) + "</td><td><select name='nip[]' class='form-control'>" +
      "<option> -- </option>" +
      "<option value='0600260'> [0600260] - [ZAENAL ABIDIN] </option>" +
      "<option value='0802781'> [0802781] - [SATIBI ] </option>" +
      "<option value='0903380'> [0903380] - [JUDY SJARIP] </option>" +
      "<option value='1105605'> [1105605] - [YULIANTI HENDARSIH] </option>" +
      "<option value='1106975'> [1106975] - [ABDUL ROCHIM] </option>" +
      "<option value='120442130008'> [120442130008] - [CHOIRUL ILYAS] </option>" +
      "<option value='1207246'> [1207246] - [ACHMAD MAULANA] </option>" +
      "<option value='123456'> [123456] - [Test] </option>" +
      "<option value='1309713'> [1309713] - [LITICIA SOCA LAWRENDRA ] </option>" +
      "<option value='1411097'> [1411097] - [RAMDAN NUR] </option>" +
      "<option value='1411517'> [1411517] - [JULIMAN YASONASA GEA ] </option>" +
      "<option value='1411795'> [1411795] - [NOVIANTO CHRIS HENDARWAN] </option>" +
      "<option value='1412021'> [1412021] - [WALUYO SUPRIADI] </option>" +
      "<option value='1412717'> [1412717] - [ADDINUL FAUZAN ] </option>" +
      "<option value='1412774'> [1412774] - [ABDUL FATAH] </option>" +
      "<option value='1500575'> [1500575] - [BAGUS SUSETYO] </option>" +
      "<option value='1500701'> [1500701] - [AHMAT SUPARDI] </option>" +
      "<option value='1501815'> [1501815] - [KHAIRUNNAS ] </option>" +
      "<option value='1501971'> [1501971] - [SHELLY DINI DEBYANZAH] </option>" +
      "<option value='1502017'> [1502017] - [CHOIRUL ILYAS] </option>" +
      "<option value='1602762'> [1602762] - [BOBY KURNIAWAN] </option>" +
      "<option value='1603240'> [1603240] - [TOTO MARYOTO] </option>" +
      "</select> </td>");
  });

  $("#delete_row").click(function() {
    if (i > 1) {
      $("#ke" + i).remove();
      i--;
    }
  });
