Menu
I have a table (id="docsTable") whose rows look similar to this:
<tr bgcolor="#E7DDCC">
<td align="center"><input type="checkbox" name="docsToAddToClass[]" value="35" /></td>
<td>Document Title</td>
<td>Document Description.</td>
</tr>
I need to iterate through the table, determine which checkboxes the user has checked, and for the rows with a checked checkbox, grab the value for the first and the text for the next two.
I don't need to build a collection: Within each iteration I want to change some elements elsewhere. That's not the hard part (for me). It's trying to figure out how to iterate through the table and select only the s with checked checkboxes.

You can try something along this line:
$('tr > td:first-child > input:checked').each(function() {
// $(this).val() is the value of the input
// $(this).parent().siblings() will refer to the two <td>'s
// You can also try other traversal methods like $(this).parent().next()
});
Hope this works and helps!
