这是一个非常简单的问题。我基本上知道我想要什么,怎么做,我很不确定哪个选择器在某个部分使用。如果我拿走toggle()函数,动画效果很好,但它只能打开菜单,而不能关闭它。
这是我的jquery代码
$(document).ready(function(){
$('#menu_button').click(function(){
$(????).toggle(function(){
$('.sidebar_menu').animate({left:'0'}, 'slow');
$('.wrapper').animate({'margin-left':'250px'}, 'slow');
});
})
});
这是我的页面代码:
<div class="sidebar_menu">
<h2>Menu</h2>
<h3>1. Escolher produto</h3>
<ul>
<li>Entradas</li>
<li>Peixe</li>
<li>Saladas</li>
</ul>
<h3>2. Preencher dados</h3>
<h3>3. Finalizar pedido</h3>
</div>
<div class="wrapper">
<header>
<button id="menu_button">menu</button>
</header>
</div>

以下是正确使用代码的小提琴:http://jsfiddle.net/6zg7K/1/
您需要将$('.sidebar_menu').animate({'left':(state ? -250: 0)}, 'slow');
添加到adeneo提供的代码中,因此您的整个功能将是:
$('#menu_button').on('click', function(){
var state = parseInt($('.wrapper').css('margin-left'),10) > 200;
$('.sidebar_menu').animate({'left':(state ? -250: 0)}, 'slow');
$('.wrapper').animate({'margin-left': (state ? 0 : 250)}, 'slow');
});
此代码是adeneo的修改版本。代码的所有功劳都归他所有。

您必须根据元素左边距创建某种切换功能:
$(document).ready(function(){
$('#menu_button').on('click', function(){
var state = parseInt($('.wrapper').css('margin-left'),10) > 200;
$('.sidebar_menu').animate({left:'0'}, 'slow');
$('.wrapper').animate({'margin-left': (state ? 0 : 250)}, 'slow');
});
});
