这是javascript。我只想在手风琴中单击选项卡时将类添加到可折叠选项卡，并希望在模式关闭但事件显示.bs.collapse或显示.bs.mod未触发时关闭所有手风琴。

$('#myModal').on('hidden.bs.modal', function () {
$('.collapse').collapse('hide');
});
$('#myModal').on('shown.bs.modal', function () {
$('#collapse1').collapse('show');
});
$('#accordion').find('.panel-default:has(".in")').addClass('panel-danger');
$('#accordion').on('show.bs.collapse', function (e) {
$(e.target).closest('.panel-default').addClass(' panel-danger');
}).on('hide.bs.collapse', function (e) {
$(e.target).closest('.panel-default').removeClass(' panel-danger');
})

Answer 1

您忘记在代码中使用该事件。 它应该是$('#myModal').on('click','hidden.bs.modal', function () {而不是$('#myModal').on('hidden.bs.modal', function () {。这是工作示例...

$('#myModal').on('click','hidden.bs.modal', function () {
$('.collapse').collapse('hide');
});
$('#myModal').on('click','shown.bs.modal', function () {
$('#collapse1').collapse('show');
});
$('#accordion').find('.panel-default:has(".in")').addClass('panel-danger');
$('#accordion').on('click','show.bs.collapse', function (e) {
$(e.target).closest('.panel-default').addClass(' panel-danger');
}).on('hide.bs.collapse', function (e) {
$(e.target).closest('.panel-default').removeClass(' panel-danger');
})

最后我解决了这个问题。我把我的jquery代码放进去

$（document）.ready（function（）{ ................法典。。。。。。。。。。。。}）;
