Jquery隐藏/显示div但也保留来自 "hiding"的切换链接

Question

我刚刚发布了 question在 stackoverflow 上关于我遇到的隐藏/显示问题，但已解决，尽管这是后续问题，因为我遇到了另一个问题。

好的，所以我有一个粘性页脚导航，并且导航上方有一个链接(也是“粘性”)，上面写着“切换菜单”...当我单击隐藏菜单时，我会看到该链接刚刚点击也隐藏。所以基本上没有办法让菜单再次可见，因为切换按钮也消失了!

Javascript:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.js" 
type="text/javascript"></script>
<script type="text/javascript">

$(document).ready(function(){

    $("#stickyfooter").show();
    $(".show_hide").show();

$('.show_hide').click(function(){
$("#stickyfooter").slideToggle("slow");
});


});

</script>

HTML:

<div id="stickyfooter">
<div id="stick_footer_title"><a class="show_hide" href="#">Toggle Menu &#x25BC;
</a></div>

<ul id="footer_menu"> 
<li class="imgmenu"><a href="#"></a></li>

<li><a href="#intro">Intro</a></li>
<li><a href="#photos">Photos</a></li>

</ul>
</div>

现在我知道 stick_footer_title 位于隐藏的 div 中(因此它消失了)，但我不知道如何制作它，以便当我单击“切换菜单”时链接会降低菜单即将消失，但仍然显示，并且可以再次单击以显示升起/显示导航。

我尝试过摆弄 Jquery，但我不擅长使用 jquery。我很确定我需要在 Jquery 中做一些事情，比如 .show();参数，但我只是猜测尝试正确处理。

有什么解决办法吗？

一般CSS:

#sticky_footer_title { position:absolute; top: -35px; left: 20px; background-
color:#FF0000; font-family:Arial, Helvetica, sans-serif; font-size: 18px; color:#FFF; 
text-shadow:none;line-height: 34px; padding: 0px 20px 0px 20px }


#stickyfooter {
position: fixed;
bottom: 0px;
margin:0 auto;
width: 960px;
left:52%;
margin-left:-530px;
height: 40px;
background:#e9e9e9;
border-top: 1px solid #e9e9e9;
padding:0px 10px 0px 10px;
font-family:Arial, Helvetica, sans-serif;
z-index:1200;


/* CSS3 Stylings - Creates the double top border */
-moz-box-shadow: 0px -1px 0px #e9e9e9;
-webkit-box-shadow:  0px -1px 0px #e9e9e9;
box-shadow:  0px -1px 0px #e9e9e9;

/* CSS3 Rounded Corners */
-moz-border-radius: 10px 10px 0px 0px;
-webkit-border-radius: 10px 10px 0px 0px;
border-radius: 10px 10px 0px 0px;

/* CSS3 Stylings - Creates the gradient background */
background: -moz-linear-gradient(top, #FFF, #e9e9e9);
background: -webkit-gradient(linear, 0% 0%, 0% 100%, from(#e9e9e9), to(#FFF));
}

您需要将粘性页脚切换出粘性页脚 div。以下代码应该适合您:

HTML:

<div class="stickyfooter">
    <div id="sticky_footer_title"><a class="show_hide" href="#">Toggle Menu &#x25BC;</a></div>
    <div id="stickyfooter">
        <ul id="footer_menu"> 
            <li class="imgmenu"><a href="#"></a></li>
            <li><a href="#intro">Intro</a></li>
            <li><a href="#photos">Photos</a></li>
        </ul>
    </div>
</div>

Javascript:

var $showhide = $(".show_hide");
var $stickyfooter = $("#stickyfooter");
var $stickyfootertitle = $("#sticky_footer_title ");

$stickyfooter.show();
$showhide.show();

$showhide.click(function(){
    var showMenu = $("#stickyfooter").css("display") == "block";

    $stickyfooter.slideToggle("slow");

    if(showMenu )
    {
        $stickyfootertitle.animate({
            bottom:'0px'
        }, "slow");
    }
    else
    {
       $stickyfootertitle.animate({
            bottom:'40px'
        }, "slow");
    }
});

CSS:

#sticky_footer_title { 
    position:absolute; 
    bottom: 40px; 
    left: 50px; 
    background-color:#FF0000; 
    font-family:Arial, Helvetica, sans-serif; 
    font-size: 18px; 
    color:#FFF; 
    text-shadow:none;
    line-height: 34px; 
    padding: 0px 20px 0px 20px; 
}


.stickyfooter {
    position: fixed;
    bottom: 0px;
    margin:0 auto;
    width: 400px;
}

#stickyfooter {
    height: 40px;
