On clicking a span, remove all classes from the other spans under the same parent

There have been a few questions that are similar but are either too broad or don't show good example code.

All I want to do is if a user clicks on span bButton, then the selected class is removed from all of the other spans and replaced with the notSelected class.

<div id="mainNav">
  <span id="aButton" class="button selected">a</span>
  <span id="bButton" class="button notSelected"&g开发者_高级运维t;b</span>
  <span id="cButton" class="button notSelected">c</span>
</div>

What is the jQuery solution to this?

Thanks!

1. Remove the notSelected class from the clicked element.
2. Add the selected class to the clicked element.
3. Remove the selected class from all siblings.
4. Add the notSelected class to all siblings.

$('#mainNav > span').click(function() {

       $(this)
        .removeClass('notSelected')
        .addClass('selected')
        .siblings()
         .removeClass('selected')
         .addClass('notSelected');

});

jsFiddle.

As a sidenote, I wouldn't bother with the notSelected class.

You could decide on which element is selected by the presence of selected or not. If the element does not have the selected class, then it is not selected.

Try this:

$('span').click(function(){
  $(this).parent().children('span').each(function(){
    $(this).removeClass('selected').addClass('notSelected');
  });
  $(this).removeClass('notSelected').addClass('selected');
});

$('span').live('click',function(){

$(this).removeClass('notSelected');
$(this).addClass('selected');


    $(this).siblings().each(function(){

          $(this).removeClass('Selected');
          $(this).addClass('notSelected');

    });

});
