我正在努力让手风琴在悬停而不是点击它我尝试了一些代码，但每次所有div .panel-collapse同时可见而且无法正常工作。
如果可能，请有人修改我的代码。
function toggleChevron(e) {
$(e.target)
.prev('.panel-heading')
.find("i.indicator")
.toggleClass('glyphicon-chevron-down glyphicon-chevron-up');
}
$('#accordion').on('hidden.bs.collapse', toggleChevron);
$('#accordion').on('shown.bs.collapse', toggleChevron);
/**####### COde I tried for onmouseover function #######**/
jQuery(function ($) {
$('#accordion a.accordion-toggle').mouseover(function () {
$(this).removeClass('collapsed').closest('.panel-collapse').addClass('in');
})
$('#accordion a.accordion-toggle').mouseout(function () {
$(this).addClass('collapsed');
})
