jquery - Bootstrap 2.3 嵌套 Accordion 图标更改也发生在父级上

Question

我正在使用 bootstrap 2.3 嵌套 Accordion 。还编写了 JQuery 来更改打开和关闭时的图标。但问题是，当嵌套 Accordion 打开时，父级 Accordion 的图标也会发生变化。

谁能帮我解决这个问题。

Sample Fiddle

$('.accordion-group').on('show', function() {
    $(this).find('.accordion-toggle').removeClass('arrow-down').addClass('arrow-up');
});    
$('.accordion-group').on('hide', function() {
    $(this).find('.accordion-toggle').removeClass('arrow-up').addClass('arrow-down');
});  

.arrow-down {

Answer 1

使用stopPropagation()

代码:

    $('.accordion-group').on('show', function(e) {
        $(this).find('.accordion-toggle').removeClass('arrow-down').addClass('arrow-up');
        e.stopPropagation();
    });
    $('.accordion-group').on('hide', function(e) {
        $(this).find('.accordion-toggle').removeClass('arrow-up').addClass('arrow-down');
        e.stopPropagation();
    });
