How to modify attribute ROWSPAN with jQuery?

Question

<table border="1">
    <tr><td>111</td><td>22</td><td rowspan="3">ads</td></tr>
    <tr><td>111</td><td class="remove">22</td></tr>
    <tr><td>111</td><td class="remove">22</td></tr>
    <tr><td>111</td><td>22</td><td rowspan="3">ads</td></tr>
    <tr><td>111</td><td class="remove">22</td></tr>
    <tr><td>111</td><td class="remove">22</td></tr>
    <tr><td>111</td><td>22</td><td rowspan="3">ads</td></tr>
    <tr><td>111</td><td class="remove">22</td></tr>
    <tr><td>111</td><td class="remove">22</td></tr>
</table>

$('.remove').click(function(){
   $(this).parent().remove();
})

If I remove TR then table is breaks because ROWSPAN is too large. Is possible modify ROWSPAN? If yes, how?

Answer 1

 $('.remove').click(function(){
     $(this).parent()
            .prevAll('tr:has(td[rowspan]):first')
            .find('td[rowspan]')
            .attr('rowspan', function(i, rs) { return rs - 1; })
            .end()
            .end()
            .remove();
 });

• .parent()
• .prevAll()
• element-selector
• has-selector
• has-attribute-selector
• first-selector
• .find()
• .attr()
• .end()
• .remove()

Answer 2

I would expect the attr() method to work... try this:

$('selector for the element you want to modify').attr('rowspan', 'newvalue');

For example:

$('#myCell').attr('rowspan', '2');
