jquery - 嵌套元素不会删除父类

Question

该类设置在 <li>通过点击它。现在，嵌套元素 ( <button> ) 不会从其父元素中删除该类。

提前致谢。

$(document).ready(function() {
      $('.pickOne li').click(function() {
        $(this).addClass('active');
      });

      $('.settingsCancelBtn').click(function() {
        $(this).parent().parent().removeClass('active');
      });
    });

HTML 如下所示:

<div class="fromCamp pickOne four">
                <ul class="four">
                    <li class="first bus"><a href="#" alt="By Bus"></a>
                        <div>
                            <p class="cmInfo">Arrive between 9 AM and 11 AM. Read these <a href="#">additional instructions</a>. <a href="#">Driving Directions</a></p>
                            <p><a href="#">Tilefishes</a></p>
                            <p><a href="#">Bluefishes</a></p>
                            <p><a href="#">Tigerfishes</a></p>
                            <button class="cmCancelDeleteButton settingsCancelBtn" type="button">Cancel</button>
                            <button class="cmGoButton settingsSaveBtn" type="button">Save</button>

好的，这就是发生的事情:

因为您的按钮包含在 LI 中，所以当您单击该按钮时，它会删除该类，然后事件继续传播并重新应用该类。

所以它正在删除；它只是立即重新申请。所以添加

  // Dont forget to put the e in function()
  $('.settingsCancelBtn').click(function(e) {
    $(this).parent().parent().removeClass('active');

    // This is the new line!
    e.stopPropagation();
  });
