How to append a lot of divs with a unique id's

Hi,

How can I append a div using JQuery with a unique id? For example:

This is my JQuery code:

var counter = 1;

$('.button').click(function(){
    $('.body_div').append('<div></div>');
    var div ('.body_div > div');
    $(div).addClass('selected');

    if($(div).hasClass('selected')){
        $(div).attr('id', 'id' + counter++);
    }
});

If I click on the button the ID will be same for all the divs which is appended

Hi Dustin, Can you explain this a little more? Do you have any html markup you could show for this example?

You could do it like this:

var counter = 1;

$('.button').click(function(){
  var $newDiv = $("<div></div>");
  $newDiv.attr("id", "newDiv" + counter++);
  $(".body_div").append($newDiv);
});

Here's a CodePen to illustrate.
