bootstrap 4模態函數在單擊時不起作用

Question

我有一個模態，當單擊該按鈕的按鈕時，此示例將發生一個操作，寫入控制台。 模態是開放的，但事件沒有發生。

HTML文件

<button type='button' data-toggle="modal" data-target="#myModal">Launch modal</button>
Open modal
</button>

<!-- The Modal -->
<div class="modal" id="myModal">

JS文件

jQuery.noConflict();
(function($){
  $(function() {
    $('#myModal').on('show.bs.modal', function(e) {
      console.log('new button clicked');
    });
  });
})(jQuery);

Answer 1

<button type='button' data-toggle="modal" data-target="#myModal">Open modal</button>

<!-- The Modal -->
<div class="modal" id="myModal">

嘗試上面的操作將打開您的模態...您只有兩個關閉標簽的按鈕，即</button>

Answer 2

您的代碼可以完美地工作

 $('button[data-target="#myModal"]').on( "click", function() { console.log('clicked') }); $('#myModal').on('shown.bs.modal', function () { console.log('modal opened') })
