如何在删除删除php中的行后重新排序序列号

Question

这是我的代码，我试图删除一行并添加一个新的。它从数据库中删除记录，删除记录后我想显示保留数据并删除表中的特定行。但它似乎不合适。请帮助一些人

<?php for($i=0; $i<$this->labNumber; $i++):
                $divlabcapdisp="divlabcap_".$i;
                $divlabcoursedispdisp="divlabcoursedisp_".$i;
                ?>
                <div class="form-group clone_field_2">
                    <div class="content-div">
                        <div class="col-sm-1">
                            <label class="control-label">Lab <?=$i+1?></label>
                        </div>
                        <div class="col-sm-2">
                            <?=$this->deliverelement($this->labElement[$i])?>
                        </div>
                        <div class="col-sm-3">
                            <?=$this->deliverelement($this->labtypeElement[$i])?>
                        </div>
                        <div class="col-sm-2">
                            <div style="display:<?php if($this->$divlabcapdisp==OT_YES):?>inline<?php else:?>none<?php endif;?>">
                                <?=$this->deliverelement($this->labcapElement[$i])?>
                            </div>
                        </div>
                        <div class="col-sm-3">
                            <div style="display:<?php if($this->$divlabcoursedispdisp==OT_YES):?>inline<?php else:?>none<?php endif;?>">
                                <?=$this->deliverelement($this->labcourseElement[$i])?>
                            </div>
                        </div>
                        <div class="col-sm-1 text-red" <?php if($i==0):?>style="display:none;"<?php endif;?>>
                            <i class="fa fa-fw fa-trash-o fa-lg" onClick="deleteButton1(this,'clone_field_2')"></i>
                        </div>
                    </div>
                </div>

并且onclick函数是

function deleteButton1(link,clonefield)
{
    var rowCount = $('.'+clonefield).length;
    var minCount = 1;

    if(rowCount > minCount)
    {
        $(link).closest('.'+clonefield).remove();
    }
    else
    {
        alert("You cannot delete the last row");
    }
}

nearest（）适用于祖先树你要找的是 parent（）

替换此

if(rowCount > minCount)
    {
        $(link).closest('.'+clonefield).remove();
    }

与

  if(rowCount > minCount)
        {
            $(link).parent('div').parent('div').fadeOut(200, function() { $(link).remove(); });
        }
