javascript - 单击一个 Accordion 时，多个 Bootstrap Accordion 会折叠其他 Accordion

标签 javascript jquery twitter-bootstrap accordion

我尝试了以下代码，除了 FontAwesome 图标之外，一切都很好。我尝试在 Google 上寻找解决方案，但找不到我正在寻找的解决方案。

当我单击其中一个 Accordion 时，另一个 Accordion 应折叠，当前单击的 Accordion 应打开，同时 fa 图标应根据 Accordion 位置进行更改。

这是我迄今为止尝试过的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');
    });

});

最佳答案

首先，您没有在代码中链接 bootstrap.min.js 文件。如果您想使用 bootstrap，则需要包含其 bootstrap.min.css 文件及其 bootstrap.min.js 文件来为您完成所有操作。

您需要以下代码才能根据您的要求工作。通过使用 not(this) 它将为您提供除当前单击的项目之外的所有元素。这样您就可以重置所有其他元素上的 Fa 图标，并在您的此元素上应用特定图标。

$('.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');

    }
});

Here is working JSFiddle.
