javascript - Bootstrap 3 从 URL 展开 Accordion

Question

使用 Bootstrap 3，我尝试使用子导航 anchor 链接(即 index.php#wnsh)展开指定的 Accordion 并将页面向下锚定到内容。我曾尝试搜索示例但运气不佳，可能是因为我的 Accordion 结构与给定的 BS3 示例不同。这是我的 HTML:

更新:

对代码进行了一些更新，但它仍然没有打开哈希指定的 Accordion 。还有什么想法吗？

            <div id="accordion" class="accordion-group">                
                <div class="panel">
                    <h4 id="cs" class="accordion-title"><a data-toggle="collapse" data-parent="#accordion" data-target="#cs_c">Child Survival: Boosting Immunity and Managing Diarrhoea</a></h4>
                    <div id="cs_c" class="accordion-collapse collapse in">
                        <p>...</p>
                    </div>

                    <h4 id="chgd" class="accordion-title"><a data-toggle="collapse" data-parent="#accordion" data-target="#chgd_c">Child Health, Growth and Development: Preventing Mental Impairment with Iodine and Iron</a></h4>
                    <div id="chgd_c" class="accordion-collapse collapse">
                        <p>...</p>
                    </div>

                    <h4 id="wmnh" class="accordion-title"><a data-toggle="collapse" data-parent="#accordion" data-target="#wmnh_c">Women’s and Newborn Survival and Health: Iron Supplementation and Food Fortification</a></h4>
                    <div id="wmnh_c" class="accordion-collapse collapse">
                        <p>...</p>
                    </div>
                </div>
            </div>

JS

var elementIdToScroll =  window.location.hash;

if(window.location.hash != ''){
  $("#accordion .in").removeClass("in");
  $(elementIdToScroll).addClass("in");
   $('html,body').animate({scrollTop: $(elementIdToScroll).offset().top},'slow');
}

提前致谢。任何帮助将不胜感激。

在 Bootstrap 3.3.5 中测试和工作。

<script type="text/javascript">
$(document).ready(function () {
    if(location.hash != null && location.hash != ""){
        $('.collapse').removeClass('in');
        $(location.hash + '.collapse').collapse('show');
    }
});
</script>
