javascript - 如果打开或关闭 Accordion ，则交换 jQuery Accordion 的标题

Question

我已经完成了 95%(我希望如此)。我正在开发一个 Accordion 功能，该功能可以根据 Accordion 打开或关闭来更改 Accordion 头部的文本。 (我有正负图像工作)。

目前，如果客户端单击 Accordion 打开和关闭它，标题会正确更改，但如果客户端打开不同的 Accordion ，原始 Accordion 将向上滑动，但标题不会更新。我尝试了一些我认为可行的选择，但尚未成功。

我做了一个jsfiddle here

jquery 是:

 $(document).ready(function() {
// accordion functionality 
$('.accordion-head').click(function(e){
    var content = $(this).parent().find('.accordion-content');
    var head = $(this).parent().find('.accordion-head');
    var $showMore = "Show me more";
    var $hideContent = "Hide this offer";            

    content.addClass('actual');

    $('.accordion-content').not('.actual').each(function(){
        if ($(this).hasClass('accordion-opened')){
            $(this).slideUp(200,function(){
                $(this).toggleClass('accordion-opened');
                $(this).parent().find('.accordion-head').toggleClass('accordion-open');
            });
        }
    });

    $(this).toggleClass('accordion-open');
    content.removeClass('actual');               

    if($(this).hasClass('accordion-open')){
        content.slideDown(200,function(){
            content.toggleClass('accordion-opened');
            head.html($hideContent);
        });
    }else{
        content.slideUp(200,function(){
            content.toggleClass('accordion-opened');
            head.html($showMore);
        });
    }
    e.preventDefault();
   });

 });​

HTML 看起来像这样:

  <div class="accordion">
         <div class="accordion-head">
                        <a href="#">
                           <span class="accordion-heading">Show me more</span>
                        </a>
                    </div>
                    <div class="accordion-content">
                        Including Thames Water, Severn Trent, Anglian Water, Yorkshire Water and many more, plus all council tax local authorities. Cashback on mortgage payments up to maximum monthly mortgage payment of £1,000.
                    </div>
                </div>


                <span class="spacer"></span>

                <div class="accordion">
                    <div class="accordion-head">
                        <a href="#">
                            <span class="accordion-heading">Show me more</span>
                        </a>
                    </div>
                    <div class="accordion-content">
                        Including British Gas, SSE, EDF Energy, E.ON, npower and many more.
                    </div>
                </div>
                <span class="spacer"></span>
            etc.

希望有人能帮忙。

您可以通过删除 head.html($showMore) 并更改来在折叠循环期间重写 header

$(this).parent().find('.accordion-head').toggleClass('accordion-open');

至

$(this).parent().find('.accordion-head').toggleClass('accordion-open').html($showMore);
