Despite almost completely copying this filtering demo, I still can't get the the plugin to remove the .selected class from the current element and add it to the one being clicked.

The current result is that the items do filter, but the .selected class remains assigned to <li><a href="#videos" data-filter="*" class="selected">All</a></li>.


HTML

<ul class="category_navigation option-set" data-option-key="filter"> 
    <li><a href="#videos" data-filter="*" class="selected">All</a></li>
    <li><a href="#videos" data-filter=".feature">Feature</a></li>
    <li><a href="#videos" data-filter=".commercial">Commercial</a></li>
    <li><a href="#videos" data-filter=".music_video">Music Video</a></li>
    <li><a href="#videos" data-filter=".trailer-promo">Trailer/Promo</a></li>
    <li><a href="#videos" data-filter=".digital">Digital</a></li>
</ul>


Javascript

// cache container
var $container = $('.videos');
// initialize isotope
$container.isotope({
});

// filter items when filter link is clicked
$('[href="#videos"]').click(function(){
  var selector = $(this).attr('data-filter');
  $container.isotope({ filter: selector });
  return false;
});


Item HTML sample

        data-lightview-type='iframe' 
        data-lightview-title="KUNG FU PANDA 2"

我没有看到任何代码来实际删除该类。我对那个插件一无所知，但你可以这样做：

$(".selected").removeClass("selected");

并将该类添加回您需要/希望将其附加到的任何元素。
