Question

尽管几乎完全复制了这个过滤demo，我仍然无法从当前元素中删除该插件以将.selected类添加到被点击的类中。

目前的结果是项目会进行过滤，但.selected类仍会分配给<li><a href="#videos" data-filter="*" class="selected">All</a></li>。

的 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>

的的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;
});

项目HTML示例

<li class="trailer-promo">
    <a href='http://player.vimeo.com/video/55078437?autoplay=1' 
        class='lightview' 
        data-lightview-group='trailer/promo'
        data-lightview-type='iframe' 
        data-lightview-title="KUNG FU PANDA 2"

Answer 1

我没有在其中看到任何实际删除该类的代码。我对这个插件一无所知，但你可以这样做：

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

并将该类添加回您需要/想要附加到的任何元素。

无法获取.selected类来更改导航项目单击
