Javascript firefox中的手风琴盒故障

我用javascript编写了下面的函数，它操作一个向上/向下滑动框。但在firefox中，它会出现故障。它只打开/关闭一次。在那之后就没有比赛了。 我从框中获取height（）参数并将其存储在隐藏输入中。但是firefox无法读取盒子的正确高度

查看代码以更好地理解：

JS:

HTML:

<section class="accBox grey">
    <header>
        <div class="title">DISCLAIMERS</div>
        <a style="display: none;" class="btnExpand" href="javascript:void(0);"><img src="/resources/images/boxExpandGrey.jpg" alt="button"></a>
        <a style="display: block;" class="btnCollapse" href="javascript:void(0);"><img src="/resources/images/boxCollapseGrey.jpg" alt="button"></a>
    </header>
    <div id="accTipsBox" style="height: 125px; padding: 0px;">
        <input type="hidden" id="boxHeight" value="125">    
        <div class="accBoxContent">
            <div><p></p><p></p><p></p></div>
        </div>
    </div>
</section>

免责声明

我想这就是你想要的：

//bind a `click` event handler to all the elements with the `btnExpandCollapse` class
$('.btnExpandCollapse').on('click', function (event) {

    //stop the default behavior of clicking the link (stop the browser from scrolling to the top of the page)
    event.preventDefault();

    //first select the parent of this element (`header` tag) and then get its sibling element that has the `accTipsBox` class, then take that element and slide it up or down depending on its current state
    $(this).parent().siblings('.accTipsBox').slideToggle(500);
});

对HTML进行一些细微的调整：

<section class="accBox grey">
    <header>
        <div class="title">DISCLAIMERS</div>

        <!-- Notice there is only one link now that does the job of both -->
        <a class="btnExpandCollapse" href="#"><img src="/resources/images/boxExpandGrey.jpg" alt="button"></a>
    </header>

    <!-- Notice I changed the ID attribute to CLASS so this code will work for repeated structure -->
    <div class="accTipsBox" style="height: 125px; padding: 0px;">  
        <div class="accBoxContent">
            <div>
                <p>1</p>
                <p>2</p>
                <p>3</p>
            </div>
        </div>
    </div>
</section>

然后您可以像这样访问这些数据

var height = $.data($('#accTipsBox')[0], 'height');

请注意，我在jQuery对象的末尾追加了

[0]

，以仅返回与该对象关联的DOM节点，这是

$.data（）方法所必需的。这是一种存储与DOM元素关联的数据的非常快速的方法

var $box = $("#accTipsBox");
$.data($box[0], 'height', $box.height());

var height = $.data($('#accTipsBox')[0], 'height');
