Get table td input values corresponding to id

i need to change value for all td's how can i all td under tr

i have DISReferralId 27 ... by this id how to filter

code :

<tr class="alter-bgcolor">
     <td class="grid_normal_column">42423</td>
        <td class="grid_normal_column">Etet Eryrytry</td>
        <td class="grid_normal_column">17/03/2014</td>

        <td class="grid_normal_column"></td>
        <td><input type="hidden" name="DISReferralId" id="27" value="27"></td>
        <td class="grid_normal_column">New</td>
  </tr>

Solution

To get the input element:

using nameattribute:

var elem = $('input[name="DISReferralId"]');

using valueattribute:
```
var elem = $('input[value="27"]');
```

using both name and value attributes:

var elem = $('input[name="DISReferralId"][value="27"]');

using id attribute:

var elem = $('#27');
// or
var elem = $('input[id="27"]');

Then to get all tds of the row containing that input:

                 parent    parent
                   td       tr        all tds
                    |        |           |
                    \/       \/          \/
var alltds = elem.parent().parent().children()

// or

                 parent   all tds excepts
                   td     input parent td  add input parent td
                    |       |               |
                    \/      \/              \/
var alltds = elem.parent().siblings().addBack()
