无法在导航项单击时更改 .selected 类

Question

尽管几乎完全复制了这个过滤demo，我仍然无法让插件从当前元素中删除.selected 类并将其添加到被单击的元素中。

当前结果是项目确实进行了过滤，但 .selected 类仍然分配给 <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;
});

Answer 1

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。
