javascript - 如何使此展开/折叠常见问题解答列表起作用？

Question

这是我想要展开/折叠的列表： 我的目标只是切换展开/折叠，让这个列表像手风琴一样。我不明白的是如何使用下面提供的 javascript 将 <div> 从隐藏状态变为可见状态。非常感谢任何资源或直接帮助。

以下是我正在使用的 JavaScript

<script type="text/javascript">
$(document).ready(function(){
    $('li a').click(function () {
        var questionname= this.name;
        $("#"+questionname).toggle();
        $(this).parent().toggleClass("minusimageapply");
    });
});
</script>

Answer 1

我可以建议一些有效的 HTML（假设 anli是仅一个olor的有效子元素，ul并且 adiv不是这些元素中的任何一个的有效子元素），例如：

<ul>
    <li class="q">Question One</li>
    <li>first answer to question one</li>
    <li>second answer to question one</li>
    <li class="q">Question two</li>
    <li>first answer to question two</li>
    <li>second answer to question two</li>
    <li class="q">Question three</li>
    <li>first answer to question three</li>
    <li>second answer to question three</li>
</ul>

和 jQuery：

$('li:not(".q")').hide();

$('li.q').click(
    function(){
        $('li:not(".q")').slideUp();
        $(this).toggleClass('open');
    });

或使用dl：

<dl>
    <dt>Question One</dt>
    <dd>first answer to question one</dd>
    <dd>second answer to question one</dd>
    <dt>Question two</dt>
    <dd>first answer to question two</dd>
    <dd>second answer to question two</dd>
    <dt>Question three</dt>
    <dd>first answer to question three</dd>
    <dd>second answer to question three</dd>
</dl>
​

和 jQuery：

$('dd').hide();

$('dt').click(
    function() {
        var toggle = $(this).nextUntil('dt');
        toggle.slideToggle();
        $('dd').not(toggle).slideUp();
    });​

试试这个

$('li a').click(function () {
    var $this = $(this);
    $this.parent().next().toggleClass("minusimageapply").slideToggle();
});​

或这个...

$('li.faq-answer').hide();
$('li.faq-question').click(function () {
    $(this).next().slideToggle();
});

li {
        list-style:none;
}
li.faq-question {
	font-weight: 700;
}
li.faq-question:hover {
	cursor: pointer;
}
