how to change attribute "hidden" in jquery

Question

<td> <input id="check" type="checkbox" name="del_attachment_id[]" value="<?php echo $attachment['link'];?>"> </td>  <td id="delete" hidden="true"> the file will be deleted from the newsletter </td> 

I want to know how can i change the attribute "hidden" to false in Jquery when the checkbox is checked or not checked.

Answer 1

$(':checkbox').change(function(){     $('#delete').removeAttr('hidden'); }); 

Note, thanks to tip by A.Wolff, you should use removeAttr instead of setting to false. When set to false, the element will still be hidden. Therefore, removing is more effective.

Answer 2

You can use jquery attr method

$("#delete").attr("hidden",true);
