jquery - 使用带有显示/隐藏内容的持久标题

Question

我有一个页面，我希望能够使用持久标题，以及单击 adiv并让它像手风琴一样工作。当我单独使用它们时，我能够处理这两个部分，但是当我将它们放在一起时代码将不起作用

HTML

<div class="main">
<div>
    <section>
        <h2 class="actog">Header</h2>
        <div class="accon">
            <!--Content Here-->
        </div>
    </section>
    <section>
        <h2 class="actog">Different Header</h2>
        <div class="accon">
            <!--Content Here-->
        </div>
    </section>
    <section>
        <h2 class="actog">Another Header</h2>
        <div class="accon">
            <!--Content Here-->
        </div>
    </section>
</div>
</div>

CSS

.actog {
    color:black;
    margin:5px 0;
    padding:5px;
    width:100%;
    height:auto;
    background-color:green;
    /* Transitions */
}
.actog:hover, .active{
    cursor:pointer;
    text-decoration:underline;
    color:#ff385b;
    background-color:pink;
}
.accon{padding:5px 0;}
.floatingHeader {
    position: fixed;
    margin-top: 0;
    top:0;
    visibility: hidden;
}

而这两个 jQuery 片段

jQuery(document).ready(function() {
        jQuery(".actog").next(".accon").hide();
        jQuery(".actog").click(function(){
           $('.active').not(this).toggleClass('active').next('.accon').slideToggle(500);
            $(this).toggleClass('active').next().slideToggle(400);
        });
    });

function UpdateTableHeaders() {
       $(".main div section").each(function() {

           var el             = $(this),
               offset         = el.offset(),
               scrollTop      = $(window).scrollTop(),
               floatingHeader = $(".floatingHeader", this)

           if ((scrollTop > offset.top) && (scrollTop < offset.top + el.height())) {
               floatingHeader.css({
                "visibility": "visible"
               });
           } else {
               floatingHeader.css({
                "visibility": "hidden"
               });      
           };
       });
    }

    // DOM Ready      
    $(function() {

       var clonedHeaderRow;

       $(".main div section").each(function() {
           clonedHeaderRow = $(".actog", this);
           clonedHeaderRow
             .before(clonedHeaderRow.clone())
             .css("width", clonedHeaderRow.width())
             .addClass("floatingHeader");

       });

       $(window)
        .scroll(UpdateTableHeaders)
        .trigger("scroll");

    });

这是一个小提琴

Answer 1

好的，问题是您正在使用next()

$('.active').not(this).toggleClass('active').next('.accon').slideToggle(500);
$(this).toggleClass('active').next().slideToggle(400);

当你需要使用siblings()

$('.active').not(this).toggleClass('active').siblings('.accon').slideToggle(500);
$(this).toggleClass('active').siblings('.accon').slideToggle(400);

在这里提琴

Answer 2

我想出了最终的解决方案

CSS

.actog {
color: black;
margin: 5px 0;
padding: 5px;
height: auto;
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
-ms-box-sizing: border-box;
box-sizing: border-box;
background-color: green;
-webkit-transition: .25s;
-moz-transition: .25s;
-o-transition: .25s;
-ms-transition: .25s;
transition: .25s;
}
.actog:hover,.active,.activeClone {
cursor: pointer;
text-decoration: underline;
color: #ff385b;
background-color: pink;
}
.accon {padding: 5px 0; width: 100%;}
.floatingHeader {
position: fixed;
margin-top: 0;
top: 0;
visibility: hidden;
display: none;
}
