jquery - 如何使用这个例子 addClass 和 removeClass

Question

这将从 thumbs class addClass active 中删除 active 类，另一个类都是 removeClass active，但我不知道该怎么做。

    $(document).ready(function(){
         $(".thumbgallery .thumb a").click(function(e) {
        $(this).parent().addClass("active");
        $(this).parent().removeClass("active");

        var href = $(this).attr("href");
        $(".largethumb img").attr("src",href);
        e.preventDefault();
        return false;
      });
    });

      //html

<div class="largethumb">
         <img src="images/detail/ref.jpg"/>
         <a class="left" href="#"> <i class="icon-chevron-left"></i></a>
        <a class="right" href="#"> <i class="icon-chevron-right"></i></a> 
 </div> <!-- End largeImage -->

  <div class="thumbgallery clearfix">
     <div class="thumb active"><a href="images/detail/ref.jpg"><img src="images/detail/ref.jpg"/></a></div>
    <div class="thumb"><a href="images/detail/car2.jpg"><img src="images/detail/car2.jpg"/></a></div>
    <div class="thumb"><a href="images/detail/car3.jpg"><img src="images/detail/car3.jpg"/></a></div>
    <div class="thumb"><a href="images/detail/car4.jpg"><img src="images/detail/car4.jpg"/></a></div>
    <div class="thumb"><a href="images/detail/car5.jpg"><img src="images/detail/car5.jpg"/></a></div>
    <div class="thumb"><a href="images/detail/car6.jpg"><img src="images/detail/car6.jpg"/></a></div>                       
    <div class="thumb"><a href="images/detail/car1.jpg"><img src="images/detail/car1.jpg"/></a></div>
     <div class="thumb"><a href="images/detail/car6.jpg"><img src="images/detail/car6.jpg"/></a></div>          
   </div>

Answer 1

我想，您想在单击的 div 上应用“事件”类并从其他 div 中删除？

如果是，那么你应该使用:

$(".thumbgallery .thumb a").click(function(e) {
      $('.thumb').removeClass("active");  //-- Remove "active" from all elements with "thumb" class     
      $(this).parent().addClass("active"); //-- Add class on clicked anchor tag's parent element
      var href = $(this).attr("href");
      $(".largethumb img").attr("src",href);
      e.preventDefault();
      return false;
});
