如何从标题行ID中获取JQuery Accordion的索引？

Question

我有一个Accordion,我想通过它的ID获取特定标题的索引.

手风琴由转发器生成:

<asp:Repeater ID="rptProjectList" OnItemDataBound="rptProjects_ItemDataBound" runat="server">
    <HeaderTemplate>
        <div id="accordion">
    </HeaderTemplate>

    <ItemTemplate>
        <h1 style="margin: 0px" class="accordionHeader" id='<%# Eval("projectCode") %>'></h1>

        <div>
           ....some stuff             
        </div>
    </ItemTemplate>

    <FooterTemplate>
        </div>
    </FooterTemplate>
</asp:Repeater>

我希望能够在展开特定部分的情况下打开页面,并将projectCode作为参数.例如,用户转到MyPage.aspx？project = ABC123,页面加载ABC123项目打开,其他面板折叠.

我的jQuery是:

var activeProject = $(document).getUrlParam("project");

获取代码.

和

$j('#accordion').accordion({
        active: activeIndex,
        collapsible: true
    });

设置手风琴.

我无法弄清楚的是中间位.我需要通过迭代div来获取activeIndex,以获得具有相关项目代码的行的索引.

你可以这样做 手风琴活跃

var active = $( ".selector" ).accordion( "option", "active" ); //getter 



<div id="accordion">
  <h3 class='headAcc'>First header</h3>
  <div>First content panel</div>
  <h3 class='headAcc'>Second header</h3>
  <div>Second content panel</div>
</div>

JQuery的

$('#accordion').accordion({
});

//suppose you want to show thee index which starts some text 
var indexToActivate = $('.headAcc:contains("Second header")').index();
alert(indexToActivate);
indexToActivate=indexToActivate-1; //index is zero based for jquery ui. 
$('button').on('click',function(){
    var active = $( "#accordion" ).accordion( "option", "active" ); //getter 
    alert('Current Index is ' + active +" ");

     $( "#accordion" ).accordion( "option", "active",indexToActivate ); //setter

     var active = $( "#accordion" ).accordion( "option", "active" ); //getter 
       alert('Current New Index is ' + active +" ");
});
