Jquery - Perform callback after append

Question

I am appending content to a list using:

  $('a.ui-icon-cart').click(function(){
         $(this).closest('li').clone().appendTo('#cart ul');
  });

I want to perform further functions to the appended content (change class, apply animations etc)

How can I perform a callback on this function that will allow me to perform functions on the appended data?

Answer 1

jQuery's .each() takes a callback function and applies it to each element in the jQuery object.

Imagine something like this:

$('a.ui-icon-cart').click(function(){
  $(this).closest('li').clone().appendTo('#cart ul').each(function() {
    $(this).find('h5').remove(); 
    $(this).find('img').css({'height':'40px', 'width':'40px'});
    $(this).find('li').css({'height':'60px', 'width':'40px'});
  });
});

You could also just store the result and work on it instead:

$('a.ui-icon-cart').click(function(){
  var $new = $(this).closest('li').clone().appendTo('#cart ul')
  $new.find('h5').remove(); 
  $new.find('img').css({'height':'40px', 'width':'40px'});
  $new.find('li').css({'height':'60px', 'width':'40px'});
});

I would also suggest that instead of mofiying the CSS like that you just add a class to your cloned li like this:

$(this).closest('li').clone().addClass("new-item").appendTo('#cart ul');

Then setup some styles like:

.new-item img, .new-item li { height: 40px; width: 40px; }
.new-item h5 { display: none }
