Optimizing an avatar toggle

Question

I have a link (avatar)#qam-account-toggle and div.qam-account-items, the div containing user account links. I am toggling div on avatar click as well as click anywhere but div.qam-account-items

Here is my code. How can I optimize this better?

$('#qam-account-toggle').click(function(e){
    e.stopPropagation();
    $(this).toggleClass('account-active');
    $('.qam-account-items').fadeToggle('fast');
});

$(document).click(function(){
    $('#qam-account-toggle.account-active').removeClass('account-active');
    $('.qam-account-items:visible').hide();
});

$('.qam-account-items').click(function(event){
   event.stopPropagation();
});

I'd suggest wrapping the code in a function, so it's all in one place and can share variables. Then there's no need to find and re-find the same elements in each event handler.

Also, you're doing some extra filtering by class name and such which is unnecessary. E.g. .hide() will hide whatever's visible, so you don't need to first use :visible to find the visible elements.

function enableAccountItemsToggling() {
  // find these once
  var accountToggle = $('#qam-account-toggle'),
      accountItems  = $('.qam-account-items');

  // toggle items
  accountToggle.on("click", function (event) {
    event.stopPropagation();
    accountToggle.toggleClass('account-active');
    accountItems.fadeToggle('fast');

    // a single click is enough; no need for a persistent event handler
    // so we use .one() instead of .on()
    $(document).one("click", function () {
      accountToggle.removeClass("account-active");
      accountItems.fadeOut("fast");
    });
  });

  accountItems.on("click", function (event) {
    event.stopPropagation();
  });
}

Not much to say here, it looks pretty good. I've moved to only using .on for attaching events as I think it encourages better practices. Remember it's better to save selectors as variables if you are going to reuse them.

Instead of catching the click on .qam-account-items you can just fire the event on everything but those classes;

$(document).on('click', '*:not(.qam-account-items)', function() {
    $('#qam-account-toggle.account-active').removeClass('account-active');
    $('.qam-account-items:visible').hide();
});
