将数据属性传递给模态引导程序

Question

<a class="my_link" data-val="user1" href="#">modal link</a>

我有这个链接打开一个bootstrap模式，但我需要传递数据属性“data-val”。我尝试使用javascript，但我没有得到它。你能帮我么？

您可以在模态上收听show.bs.modal事件，并将点击的元素作为事件的relatedTarget属性。检查Bootstrap模态documentation以供进一步参考。

这是一个使用Bootstrap v4的工作示例。

$('#my-modal').on('show.bs.modal', function (event) {
  var myVal = $(event.relatedTarget).data('val');
  $(this).find(".modal-body").text(myVal);
});
