在 JS 中完成另一个函数后调用一个函数

Question

我有一个菜单，当我点击一个 btn 时它会滑出，这很好，但现在我想按其他任何地方来隐藏菜单，而不仅仅是按同一个 btn。

// menu
$('.toggle').click(function(event) {
	event.preventDefault();
	$('.self').toggleClass('show-m');
	$('.toggle').toggleClass('show-t');
	$('.content').toggleClass('move-co');
});


/*
$('#s-form').submit(function(event) {
	if (!$('#search').val()) {
		event.preventDefault();
	} else {
		$.pjax.submit(event, '#result');
	}
});
*/

*{
  outline: none !important;
  box-sizing: border-box;
  transition: all 0.3s ease-in-out;
}
li {
    list-style: none;
}
.content{
  padding: 100px 0;
}
/* menu */
/* toggle */
.menu .toggle {
    padding: 10px;
    position: fixed;
    top: 20px;
    left: 0;
    z-index: 10;
    background: #111;
    color: #fff;
    border: none;
}
.show-t {
    transform: translate(300px,0);
}
/* menu self */
.menu .self {
    width: 300px;
    padding: 15px;
    position: fixed;
    top: 0;
    bottom: 0;
    left: -310px;
    z-index: 20;
    text-align: center;
    background: white;
    box-shadow: 2px 0 10px 0 rgba(0,0,0,0.5);
}
.show-m {
    left: 0 !important;
}
.menu .self ul {
    padding: 0;
}
.menu .self ul li {
    padding: 10px 0;
    margin: 10px 0;
    text-align: center;
    background: #ecf0f1;
}
.menu .self li a {
    width: 100%;
    display: inline-block;
    color: #95a5a6;
}
.move-co {
    transform: translate(250px,0);
}

在body上绑定一个事件，然后根据目标做一些动作：

// menu
$(document).click(function(event) {
    var $target = $(event.target),
        $target_is_menu = !!$target.closest('.menu').length,
        $target_is_button = !!$target.closest('.toggle').length,
        action = $target_is_button ? 'toggleClass' : 'removeClass';
  
    if($target_is_menu && !$target_is_button) return;

    if($target_is_button) event.preventDefault();
  
    $('.self')[action]('show-m');
    $('.toggle')[action]('show-t');
    $('.content')[action]('move-co');
});

*{
  outline: none !important;
  box-sizing: border-box;
  transition: all 0.3s ease-in-out;
}
li {
    list-style: none;
}
.content{
  padding: 100px 0;
}
/* menu */
/* toggle */
.menu .toggle {
    padding: 10px;
    position: fixed;
    top: 20px;
    left: 0;
    z-index: 10;
    background: #111;
    color: #fff;
    border: none;
}
.show-t {
    transform: translate(300px,0);
}
/* menu self */
.menu .self {
    width: 300px;
    padding: 15px;
    position: fixed;
    top: 0;
    bottom: 0;
    left: -310px;
    z-index: 20;
    text-align: center;
    background: white;
    box-shadow: 2px 0 10px 0 rgba(0,0,0,0.5);
}
.show-m {
    left: 0 !important;
}
.menu .self ul {
    padding: 0;
}
.menu .self ul li {
    padding: 10px 0;
    margin: 10px 0;
    text-align: center;
    background: #ecf0f1;
}
.menu .self li a {
    width: 100%;
    display: inline-block;
    color: #95a5a6;
}
.move-co {
    transform: translate(250px,0);
}

你不能使用 jQuery .hover 事件吗？ http://api.jquery.com/hover/
