bootstrap 4模态函数在单击时不起作用

Question

我有一个模态，当单击该按钮的按钮时，此示例将发生一个操作，写入控制台。 模态是开放的，但事件没有发生。

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">

尝试上面的操作将打开您的模态...您只有两个关闭标签的按钮，即</button>

Answer 2

您的代码可以完美地工作

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