javascript - 区分动态id

Question

如何使用 jQuery 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 }} 以获得通用函数。

谢谢你的帮助!

Answer 1

shown.bs.modal 事件的目标是 div.modal，您可以从中检索元素 ID – 通过一些解析，您可以得到id_seance 插入前的原始值。

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