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'之后添加一列新的专栏[NAME:CINDY AGE:21]。因为我希望添加一个新行,按照' AGE'并且[NAME:Tori AGE:26]将在' Kelly'之后追加。
<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。欢呼:)

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>');
});

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