bootstrap panel show.bs.collapse在标头上获取ajax数据，并在延迟时显示加载图标

我使用引导手风琴面板来显示数据。我需要使用ajax获取标题上的响应从服务器获取数据。下面是我在实现ajax请求所需的每个面板标题上使用的代码

示例：单击可折叠组项1需要实现ajax请求，更改编号，并在获得响应后显示加载图标而不是glyphicon V形向下，需要以1000的延迟显示glyphicon V形向下

('#accordion').on('shown.bs.collapse', function () {
   // do ajaxy stuff…
    alert('test');
   //$('#result').toggle('1000');
    //  $("i",this).toggleClass("glyphicon-chevron-down glyphicon-chevron-spinner");
 })

我的答案是使用fontawesome，而将其更改为使用glyphicons应该很容易。该脚本从可折叠标题中使用的锚标记的数据id属性中获取要与ajax请求一起发送的id。默认情况下，ajax请求自然会失败。在ajax请求后根据请求更改标题

//在此处添加您的javascript $document.readyfunction{ $'a[data toggle=collapse]'。单击，函数E{ var Myi=$e.target.next； $.ajax{ 类型：get， url:/test/testservice？id=+$e.target.dataid， 发送前：函数{ Myi.attrclass，fa-cog-fa-spin-pull-right； }, 成功：功能{ //... $e.target.htmlSuccessfull for id+$e.target.dataid； Myi.delay500.queuefunctionnext{ Myi.attrclass，fa-fa检查文本成功向右拉； 下一个 }.500； 警报已成功接收id为+$e.target.dataid的内容； }, 错误：函数{ //.. $e.target.htmlUnsuccessfull for id+$e.target.dataid； Myi.delay500.queuefunctionnext{ Myi.attrclass，fa fa乘以文本危险向右拉； 下一个 }.500； Alert无法获取id为+$e.target.dataid； } }; }; }; 动物保护协会的陈词滥调，埃尼姆·埃乌斯莫德的高寿命accusamus terry richardson广告鱿鱼。3狼月亮奥特餐厅，非丘比特滑板多洛早午餐。食品车奎奴亚藜。早午餐3狼月亮临时，太阳阿利夸放了一只鸟 在它上面，鱿鱼单一来源咖啡Nalla assumenda shoreditch et.Nihil anim keffiyeh helvetica，工艺啤酒工人wes anderson cred Nescuint sapiente ea proident。纯素食主义者，屠夫副洛莫。从工艺啤酒场到餐桌， 粗斜纹棉布美学合成器Nescuint您可能还没有听说过accusamus labore可持续VHS。 动物保护协会的陈词滥调，埃尼姆·埃乌斯莫德的高寿命accusamus terry richardson广告鱿鱼。3狼月亮奥特餐厅，非丘比特滑板多洛早午餐。食品车奎奴亚藜。早午餐3狼月亮临时，太阳阿利夸放了一只鸟 在它上面，鱿鱼单一来源咖啡Nalla assumenda shoreditch et.Nihil anim keffiyeh helvetica，工艺啤酒工人wes anderson cred Nescuint sapiente ea proident。纯素食主义者，屠夫副洛莫。从工艺啤酒场到餐桌， 粗斜纹棉布美学合成器Nescuint您可能还没有听说过accusamus labore可持续VHS。 动物保护协会的陈词滥调，埃尼姆·埃乌斯莫德的高寿命accusamus terry richardson广告鱿鱼。3狼月亮奥特餐厅，非丘比特滑板多洛早午餐。食品车奎奴亚藜。早午餐3狼月亮临时，太阳阿利夸放了一只鸟 在它上面，鱿鱼单一来源咖啡Nalla assumenda shoreditch et.Nihil anim keffiyeh helvetica，工艺啤酒工人wes anderson cred Nescuint sapiente ea proident。纯素食主义者，屠夫副洛莫。从工艺啤酒场到餐桌， 粗斜纹棉布美学合成器Nescuint您可能还没有听说过accusamus labore可持续VHS。
