Question

这里的一切都“正常”但我的动画显示不正常。我希望切换按钮在导航消失时向上移动，但“慢”不起作用。

JQuery的：

//Close and open
$(document).ready(function(){
$(".open, .close").click(function(){
    $(".navigation").slideToggle("slow");
    $(".open").toggle();
    $(".close").toggle();
    $(".navigation").css("display","inline");
    $(".collapse").toggleClass("collapse-closed","slow");
  });
});

CSS

.open{
    display:block;
    margin: 12px auto 0px;
    padding:0px;
    width: 0; 
    height: 0; 
    border-left: 13px solid transparent;
    border-right: 13px solid transparent;
    border-top: 13px solid #9b9b9b;
    transition: all 0.3s;
    -moz-transition: all 0.3s; /* Firefox 4 */
    -webkit-transition: all 0.3s; /* Safari and Chrome */
    -o-transition: all 0.3s; /* Opera */
    cursor: pointer;
}
.open:hover{
    border-top: 13px solid #A70400;
    }
.close{
    display:none;
    margin: 10px auto 0px;
    padding:0px;
    width: 0; 
    height: 0; 
    border-left: 13px solid transparent;
    border-right: 13px solid transparent;
    border-bottom: 13px solid #9b9b9b;
    transition: all 0.3s;
    -moz-transition: all 0.3s; /* Firefox 4 */
    -webkit-transition: all 0.3s; /* Safari and Chrome */
    -o-transition: all 0.3s; /* Opera */
    cursor: pointer;
}
.close:hover{
    border-bottom: 13px solid #A70400;
}
.collapse {
    background-color: #f6f6f6;
    border-radius: 4px;
    border: 1px solid #919191;
    -moz-box-shadow: 0 2px 4px #bdbdbd;
    -webkit-box-shadow: 0 2px 4px #bdbdbd;
    box-shadow: 0 2px 4px #bdbdbd;
    z-index:8;
    width: 46px;
    height: 36px;
    margin-bottom: -40px;
    right: 20px;
    position: fixed;
    top: 24px;
}
.collapse-closed {
    top: -8px;
}

.navigation {
    border-bottom: 1px solid #919191;
    -moz-box-shadow: 0 2px 4px #bdbdbd;
    -webkit-box-shadow: 0 2px 4px #bdbdbd;
    box-shadow: 0 2px 4px #bdbdbd;
    position: fixed;
    z-index: 7;
    background-color: #f6f6f6;
    width: 100%;
    margin: 0 auto;
    line-height: 0em;
    padding-top: 10px;
    padding-bottom: 10px;
}

.navigation ul {
    text-align: center;
    line-height: 0;
    margin: 10px 0;
}

.navigation ul li {
    display: inline;
    border-top-style: none;
    padding-top: 5px;
    padding-bottom: 5px;
    transition: all 0.5s;
    -moz-transition: all 0.5s; /* Firefox 4 */
    -webkit-transition: all 0.5s; /* Safari and Chrome */
    -o-transition: all 0.5s; /* Opera */
    border-bottom: 4px solid rgba(167, 4, 0, 0);
    margin-right: 8px;
    margin-left: 8px;
}

.navigation ul li:hover,
.navigation ul li:active {
    display: inline;
    border-bottom: 4px solid #A70400;
}

.navigation li a {
    text-decoration: none;
}

HTML

<div class="navigation">
        <ul>
            <li><a href="#ems">About Me</a></li>
            <li><a href="#ems">Writing Samples</a></li>
            <li><a href="#ems">Musings</a></li>
            <li><a href="#ems">Books</a></li>
        </ul>

    </div>
    <div class="collapse">
        <div class="open"></div>
        <div class="close"></div>
    </div>

我是否以某种方式阻止了转换速度？

谢谢！

将jQuery UI添加到您的页面，它将允许您为类更改设置动画（对jQuery 1.8使用UI 1.8.22）。您的代码可以正常使用UI扩展。

Fiddle

如果没有UI，则无法为类更改设置动画。您可以使用animate()传递top属性来替换这些类更改，如下所示：

$(".collapse").animate({top: ($('.collapse').css('top') === '-8px') ? 24 : -8}, 'slow');

为什么我的切换没有正确转换
