Nested element won't remove parent class

Question

The class is set on an <li> by it being clicked. Now a nested element (<button>) will not remove the class from it's parent.

Thanks in advance.

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

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

and the HTML is like so:

<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>

Answer 1

So, minutes after I posted this, my buddy presents a solution. Break points... who knew. :)

Because I was initially selecting the <li>, when I clicked on a child of it to remove the active class, it removed it, and then immediately added it again.

The solution was to select the <a> inside the <li> initially (it's set to display:block and covers the same space the li does.)

Silly me.

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

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

Okay, here's what's happening:

Because your button in contained in the LI, when you click the button, it removes the class, and then the event continues to propagate and reapplies the class.

So it IS removing; its just reapplying instantly. So add

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

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