将数据属性传递给模态引导

Question

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

我有这个链接来打开引导模式，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？

您可以听取模型上的show.bs.modal事件并获取可用的点击元素作为relatedTarget事件的属性。检查Bootstrap模式documentation以作进一步参考。

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); 
 
});
