我尝试了以下代码，除了FontAwesome图标外，一切都很好。我试图在Google上找到一些解决方案，但我无法找到我正在寻找的解决方案。
当我点击其中一个手风琴时，另一个手风琴应该折叠，当前点击的手风琴应该打开，同时应根据手风琴的位置改变fa图标。
这是我到目前为止所尝试的JSFiddle
$(document).ready(function () {
$(".accordion-body").on("shown", function (evt) {
setIcon(evt.target, true);
});
$(".accordion-body").on("hidden", function (evt) {
setIcon(evt.target, false);
});
$(".accordion-body").collapse("hide");
$("#collapse-faq-1").collapse("show");
});
$('.accordion-toggle').click(function(event) {
var id = '#'+ event.currentTarget.firstElementChild.id;
if('class == fa-chevron-down'){
$(id).removeClass('fa-chevron-down');
$(id).addClass('fa-close');
}else{
$(id).removeClass('fa-close');
$(id).addClass('fa-chevron-down');
}
});
$(function () {
var active = true;
$('#collapse-init').click(function () {
if (active) {
active = false;
$('.panel-collapse').collapse('show');
$('.panel-title').attr('data-toggle', '');
$(this).text('Enable accordion behavior');
} else {
active = true;
$('.panel-collapse').collapse('hide');
$('.panel-title').attr('data-toggle', 'collapse');
$(this).text('Disable accordion behavior');
}
});
$('#accordion').on('show.bs.collapse', function () {
if (active) $('#accordion .in').collapse('hide');
});
});

答案 0 :(得分：1)
首先，您没有链接代码中的bootstrap.min.js文件。如果你想使用bootstrap，那么你需要包含它的bootstrap.min.css文件及其bootstrap.min.js文件来为你做所有的事情。
您需要以下代码才能按照您的要求工作。通过使用not(this)，它将为您提供除当前点击项目之外的所有元素。这样您就可以在所有其他元素上重置Fa图标，并在此元素上应用特定的图标。
$('.accordion-toggle').click(function (event) {
var $this = $(this);
// It will reset all the other icons except the clicked item icon
$('.accordion-toggle').not(this).children('i').removeClass('fa-close').addClass('fa-chevron-down');
if ($this.children('i').hasClass('fa-chevron-down')) {
$this.children('i').removeClass('fa-chevron-down').addClass('fa-close');
} else {
$this.children('i').removeClass('fa-close').addClass('fa-chevron-down');
}
});
以下是您问题的嵌入式代码段。
$(function () {
$(document).ready(function () {
$(".accordion-body").on("shown", function (evt) {
setIcon(evt.target, true);
});
$(".accordion-body").on("hidden", function (evt) {
setIcon(evt.target, false);
});
$(".accordion-body").collapse("hide");
$("#collapse-faq-1").collapse("show");
});
$('.accordion-toggle').click(function (event) {
var $this = $(this);
// It will reset all the icons except the clicked (this) item.
$('.accordion-toggle').not(this).children('i').removeClass('fa-close').addClass('fa-chevron-down');
if ($this.children('i').hasClass('fa-chevron-down')) {
$this.children('i').removeClass('fa-chevron-down').addClass('fa-close');
} else {
$this.children('i').removeClass('fa-close').addClass('fa-chevron-down');
}
});
$(function () {
var active = true;
$('#collapse-init').click(function () {
if (active) {
active = false;
$('.panel-collapse').collapse('show');
$('.panel-title').attr('data-toggle', '');
$(this).text('Enable accordion behavior');
} else {
active = true;
$('.panel-collapse').collapse('hide');
$('.panel-title').attr('data-toggle', 'collapse');
$(this).text('Disable accordion behavior');
}
});
$('#accordion').on('show.bs.collapse', function () {
if (active) $('#accordion .in').collapse('hide');
});
});
});
