区分动态id

Question

如何区分动态 ID 和 jQuery？

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objective是在JS中通过任意数"replace"{{ $seance->id_seance }}找到泛型函数的方法

感谢您的帮助！

Answer 1

给他们加一个class，像这样：

$('[id^="reservationModal-"]').addClass("reservationModal");

并使用这个：

$(".reservationModal").on('shown.bs.modal', function (e) {
    console.log('works');
});

如果要区分功能，可以这样：

$(".reservationModal").each(function() {
    var currentID = this.id;
    $(this).on('shown.bs.modal' function(e) {/*...*/});
});

Answer 2

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，您可以获得 id_seance 之前的原始值它是插值的。

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