Is there a better way to get values out of a table row?
- by chobo2
Hi
Say I have this
<table border="1" id="tbl">
<tr>
<td><input type="checkbox" name="vehicle" value="Bike" /></td>
<td>row 1, cell 1</td>
<td>row 1, cell 2</td>
</tr>
<tr>
<td><input type="checkbox" name="vehicle" value="Bike" /></td>
<td>row 2, cell 1</td>
<td>row 2, cell 2</td>
</tr>
</table>
Now I want to get the row that is checked, then the cell values of that checked row. So I would do this
var cells = $('#tbl :checked').parents('tr').children('td');
So lets assume only one checkbox can be checked(so no jqueyr foreach loop).
So now say I wanted to get the 2nd table cells value I would just go
var secondCell = $(cells[1]).html();
The thing with this though it makes the code so brittle. Like what if I put another table cell after after the checkbox one?
<table border="1" id="tbl">
<tr>
<td><input type="checkbox" name="vehicle" value="Bike" /></td>
<td> I am new </td>
<td>row 1, cell 1</td>
<td>row 1, cell 2</td>
</tr>
<tr>
<td><input type="checkbox" name="vehicle" value="Bike" /></td>
<td> I am new </td>
<td>row 2, cell 1</td>
<td>row 2, cell 2</td>
</tr>
</table>
So now I have to go through my code and change this
var secondCell = $(cells[1]).html();
to this
var thirdCell = $(cells[2]).html();
since now I am actually after the 3rd cell and not the 2nd cell anymore.
So is there a better way?
Thanks
