嵌套元素不会删除父类

Question

<li>通过点击它来设置类.现在,嵌套的element(<button>)不会从它的父级中删除该类.

提前致谢.

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

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

HTML就像这样:

<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>
                        </div>
                    </li>
                    <li class="second car"><a href="#" alt="By Car"></a>
                        <div>

                            <p><a href="#">Bluefishes</a></p>
                            <p><a href="#">Tigerfishes</a></p>
                            <button class="cmCancelDeleteButton settingsCancelBtn" type="button">Cancel</button>

                        </div>
                    </li>
                    <li class="third plane"><a href="#" alt="By Plane"></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>

                            <button class="cmGoButton settingsSaveBtn" type="button">Save</button>
                        </div>
                    </li>
                    <li class="fourth stayOver"><a href="#" alt="Staying Over"></a>
                        <div>
                            <p><a href="#">Remoras</a></p>
                            <p><a href="#">Tilefishes</a></p>
                            <p><a href="#">Bluefishes</a></p>
                            <p><a href="#">Tigerfishes</a></p>

        </div>

好的,这是发生了什么:

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

所以它正在消除; 它只是立即重新申请.所以加

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

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