Question

我以某种方式使我的newRow（）函数工作。您可以在下面看到代码。现在我需要克隆整个表。我试图调整newRow（）函数来完成这项任务，显然我的尝试是不成功的。

我的js代码：

function newRow( valoda, dataTable){
    var row, table, len, tags, newRow;
    row = document.getElementById('valoda');
    table = document.getElementById('dataTable');
    tags = table.getElementsByTagName('tr');
    len = tags.length;

    newRow = row.cloneNode(true);
    newRow.id = "valoda_0" +  len;
    table.appendChild(newRow);
}

function newTable(dataTable3){
    var table, len, tags, newTable;

    table = document.getElementById('dataTable3');
    tags = table.getElementsByTagName('table');
    len = tags.length;

    newTable = row.cloneNode(true);
    newTable.id = "darbs_0" +  len;
    table.appendChild(newRow);
}

和HTML：

<fieldset class="row2">
   <legend>Iemaņas un zināšanas</legend>
   <p> 
      <input type="button" value="Pievienot" onClick="newRow( 'valoda', 'dataTable')" /> 
   <p>
   </p>
   </p>
   <table  class="virsraksti" border="1">
      <tr>
         <th style="width:25%"> Valoda</th>
         <th style="width:25%"> Runātprasme </th>
         <th style="width:25%"> Lasītprasme </th>
         <th style="width:25%"> Rakstītprasme </th>
      </tr>
   </table>
   <table id="dataTable" class="cv" border="1">
      <tbody>
         <tr id="valoda">
            <td>
               <input type="text" style="width:100%;" placeholder="ievadiet valodu">
            </td>
            <td>

      <tr>
         <td style="width:5%; text-align:left"> Datums līdz:</td>
         <td style="padding:0"> <input type="text" class="darbs"></td>
      </tr>
      <tr>
         <td style="width:5%; text-align:left"> Ieņemamais amats:</td>
         <td style="padding:0"> <input type="text" class="darbs"></td>
      </tr>
      <tr>
         <td style="width:5%; text-align:left"> Amata kategorija:</td>

      </tr>
   </table>
</fieldset>

我知道克隆表行有很多方法，但由于我要将所有输入数据放入DB，我需要一个为每个创建的元素创建uniq ID的函数，我知道newRow（）函数做到了，但是addTable（）呢？它是否只创建唯一的表ID，还是可以为表中的所有输入字段获取新的唯一ID？

我希望你明白我扭曲的问题。根据要求，如果需要，我会添加一个小提琴。

你能告诉我正确的解决方案吗？

提前非常感谢。

Answer 2

javascript：

$("#mytable").clone().appendTo(".mytarget");

HTML：

<table id="mytable">
<tr>
<td>cell1</td>
<td>cell2</td>
</tr>
</table>

<div class="mytarget"></div>
