Jquery: 在包含特定列值的行后插入新行

Jquery: Insert a new row after a row that contain specific column value

如何使用 Jquery 在具有特定列值的行之后追加新行?

例如,我希望在 'Selina' 之后追加一行新的 [NAME: CINDY AGE: 21] 列,因为我想追加一个按 'AGE' 和 [NAME: Tori AGE: 排序的新行: 26] 将附加在 'Kelly'.

之后
<table>
  <tr>
    <th>NAME</th>
    <th>AGE</th>
  </tr>
  <tbody>
    <tr>
      <td>Alice</td>
      <td>18</td>
    </tr>
    <tr>
      <td>Selina</td>
      <td>20</td>
    </tr>
    <tr>    
      <td>Kelly</td>
      <td>25</td>
    </tr>
  </tbody>
</table>
<input type="text" name="name" id="name" placeholder="NAME">
<input type="text" name="age" id="age" placeholder="AGE">
<button type="button" id="add_btn">ADD</button>

谢谢。加油:)

这应该有效:

jQuery('#add_btn').on('click',function(){
  var age = jQuery('#age').val();
  var name = jQuery('#name').val();
    var target = jQuery('tbody > tr > td:last-child').filter(function(){
    return jQuery(this).text() >= age;
  }).first().parent();
  if(target.length > 0)
    target.before('<tr><td>'+name+'</td><td>'+age+'</td></tr>');
  else
    jQuery('tbody > tr:last').after('<tr><td>'+name+'</td><td>'+age+'</td></tr>');
});

jsFiddle

function myFunction() {
  document.getElementById('test').innerHTML = document.getElementById('test').innerHTML + "<tr><td>" + document.getElementById('name').value + "</td><td>" + document.getElementById('age').value + "</td></tr>";
}
