手风琴框在firefox中出现故障

Accordion Box malfunction in firefox

本文关键字：故障 firefox 手风琴      更新时间：2023-09-26

我用javascript编写了以下函数，用于操作幻灯片上下框。但在firefox中，它会出现故障。它只打开/关闭一次。之后就没有戏了。我从框中获取高度()参数，并将其存储在隐藏输入中。但是firefox无法读取正确的方框高度。

查看代码以便更好地理解:

JS: 

function boxCollapse() {
    $("#boxHeight").attr("value", parseInt($("#accTipsBox").height()));
    $("#accTipsBox").animate({height:'0px'});
    $(".btnCollapse").css({display:'none'});
    $(".btnExpand").css({display:'block'});
    $("#accTipsBox").css({padding:'0px'});
}
function boxExpand() {
    $("#accTipsBox").animate({height: $("#boxHeight").attr("value")});
    $(".btnExpand").css({display:'none'});
    $(".btnCollapse").css({display:'block'});
    $("#accTipsBox").css({padding:'0px'});
}
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>

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);
});

稍微调整一下你的HTML:

<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>

下面是一个演示:http://jsfiddle.net/VGN64/

下面是一些文档:

  • .slideToggle(): http://api.jquery.com/slidetoggle
  • .siblings(): http://api.jquery.com/siblings
另外，如果你想存储DOM元素的数据，可以使用jQuery的$.data()方法: 
var $box = $("#accTipsBox");
$.data($box[0], 'height', $box.height());

你可以像这样访问这些数据

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

请注意，我将[0]附加到jQuery对象的末尾，以返回与该对象关联的DOM节点，这是$.data()方法所需要的:http://api.jquery.com/jquery.data。这是一种非常快速的存储与DOM元素相关的数据的方法。
