javascript - 区分动态ID

jQuery如何区分动态ID？

HTML：

@foreach($listeSeances as $seance)
    ...

    <div class="modal fade reservationModal" id="reservationModal-{{ $seance->id_seance }}" tabindex="-1" role="dialog" aria-labelledby="reservationModal-{{ $seance->id_seance }}" aria-hidden="true">
         ...
    </div>

@endforeach

JS：

$('[id^="reservationModal-"]').on('shown.bs.modal', function (e) {
    console.log('works');
});

我的目标是找到如何用JS中的任何数字“替换” {{ $seance->id_seance }}以具有通用功能。

感谢帮助！

最佳答案

shown.bs.modal事件的目标是div.modal，您可以从中检索元素ID –只需进行一点分析，就可以在插入id_seance之前获取其原始值。

$('[id^="reservationModal-"]').on('shown.bs.modal', function (e) {
    let id_seance = e.target.id.split('-').pop(-1);
    console.log('works', { id_seance });
});
