Question

我正在使用bootstrap 2.3嵌套手风琴。还要编写JQuery以在打开和关闭时更改图标。但问题是，当嵌套的手风琴打开时，父母手风琴的图标也在变化。

任何人都可以帮我解决这个问题。

$('.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');
});

＆＃13;

.arrow-down {
background: url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAwAAAAMCAYAAABWdVznAAAAAXNSR0IArs4c6QAAAARnQU1BAACxjwv8YQUAAAAJcEhZcwAAAHwAAAB8ARUP7eQAAAAYdEVYdFNvZnR3YXJlAHBhaW50Lm5ldCA0LjAuNWWFMmUAAACISURBVChTvc+xCoNAEIThDXkQH8FCYhGwsRLEgJ2lEN81VQg2toIW2qVK7z9RREEtHfjg7liWOTslIZzxeJhgYhU+uOmykwQd3rpEaNEg1cMiFzyh4Rc82BU5fqjxf5xS4AstUwMtmJNBm0r4eKCHhtViMzFUTzSsGkd/W9XbrLGXO9zxeG7MBoKmGaM1wCzfAAAAAElFTkSuQmCC) no-repeat 50%;

使用stopPropagation()

<强>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();
    });
