用jQuery指定div ID

Question

I have buttons and divs and in each part I have them with the same ID I want to get the ID of button and use it for refreshing the div html.how should I write the * section?

   $(function() {
         $(".button").click(function(){ 
         var id=$(this).attr('id');
         var dataString = 'id='+ id ;
        $.ajax({
           type: "POST",
           url: "download_number.php",
           data: dataString,
           cache: false,
           success: function(html)
           {
          *********I HAVE PROBLEM HERE**************
            $('how to get the id of the div from var id of button above?').html(html);
          } 
           });

         });
              });

Div:

  Downloaded:<div id="<?php echo $id; ?>" ><?php echo $downloadcount;?></div>

Button:

 <input type = "button" value="Download" class="button" id="<?php echo $id; ?>" name="dl">

If I get class It will update the whole divs I want to update just the div realted to the button

Answer 1

Try something like:

$('.button').attr('id');

to get the id of the button, then to change it:

$('.button').attr('id',''); //delete previous id if existing
$('.button').attr('id','yourNewId'); //set new id

then to use the new id:

$("#yourNewId").doSomething();
