Loop through all checkboxes that are inside a div tag

I need to loop through all checkboxes that are inside a div tag with id #abc123

How can I do this?

$("#abc123").foreach( ???? )

Update my html row looks like:

<tr>
<td><input .../> </td>
<td>234</td>

</tr>

I need to add the value of the <td> into the ID of the checkbox.

Would I just get the parent, t开发者_运维技巧hen ancestor it somehow?

$("#abc123 input[type=checkbox]").each(function()
     {

     });

UPDATE:

Ok, Let'd see if I got this straight. Given:

<tr> 
<td><input .../> </td> 
<td>234</td> 
</tr>

You want the result to be (effectively)

<tr> 
<td><input id="abc234" .../> </td> 
<td>234</td> 
</tr>

$("td input[type=checkbox]").each(function()
{
     var id = $(this).next("td").text();
     $(this).attr("id", "abc"+ id);
});

$("#abc123 input[type=checkbox]").each(function() {
    $(this).dosomething();
});

Use a onkeydown event... I recommend the tab key which is keycode "9"

$(document).keydown(function(e){
  if(event.keyCode == '9'){ 
  ... 
}

Inside the if statement you'll need a nested if statement that checks which element is in focus and then assigns focus to the next element like this :

document.div.id.focus();

You didn't label where #abc123 is in your code. Also, do the <td> tags have any identification? The following may work.

$("#abc123 input:checkbox").each(function(i) {
    id = $(this).closest('td').next('td').text();
    $(this).attr('id', id);
});

I am not sure how deep your <div id="abc123"> is in the <td> so I used the closest() method to get to the cell wrapper. If it is only 1 deep, i.e. there is no <div> as it appears in your code, then you can just use parent(). Good luck.
