Question

我有这个代码，我使用jQuery代码复制一个表，原始表工作正常与PHP提取查询，但复制过程不起作用，如果我添加PHP代码，但如果删除PHP代码它有效。

  <form action="" method="post" name="addusers" id="addusers">
            <div class="felements"><select name="proname" type="text" required class="tfield2" id="proname">
                <option id="0">-- Select Provider --</option>
                <?php $prov = $con->query("SELECT * FROM providers"); while ($vall = mysqli_fetch_array($prov)){ ?> 

                <option id="<?php echo $vall ['ID'];?>">
                    <?php echo $vall ['provname']?>
                </option>
                <?php } ?>
            </select></div>

            <div class="felements"><input name="invodate" type="text" required class="tfield" id="invodate" placeholder="Invoice Date"/>
                </div>
                    <div class="felements"><input name="Save" type="submit" class="button" value="Save" style="width: 91%;"></div>

        <table class="table table-borderd table-hover felements">
            <thead>

如果选择不同，您需要AJAX内容或克隆而不是插入静态行：

function addnewrow() {
  $('.detail').append($("tbody.detail tr:eq(0)").clone());
}

如何使用jquery add函数添加动态数据？
