data-role="tagsinput" 在 crome 和 edge 中工作，但不在 Internet Explorer 中

Question

我正在使用 Bootstrap 设计一个网站。 TagsInput 在 Chrome 和 Edge 中有效，但在 Internet Explorer 中无效。 标签框未出现在 Internet Explorer 中附加以下代码：-

    <!DOCTYPE html>
    <html lang="en">
        <head>
            <meta charset="utf-8" />
            <meta http-equiv="X-UA-Compatible" content="IE=edge">
            <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no" />
            <meta name="description" content="" />
            <meta name="author" content="" />
            <title>TNL metadata tagging</title>

        </head>
        <body>
            <div class="container">
              <form class="form-horizontal">
                <div class="row row-cols-1">

                  <div class="col mt-3">
                    <div class="form-group">
                        <div class="col-sm-10">
                          <input class="form-control" id="focusedInput" type="text" value="News" data-role="tagsinput" />
                        </div>
                    </div>
                  </div>
                </div>
                <button type="submit" class="btn btn-primary">Submit</button>
              </form>
            </div>
            <!-- jQuery (necessary for Bootstrap's JavaScript plugins) -->
        <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
      <!-- Latest compiled and minified JavaScript -->
    
    <script type="text/javascript" src="js/bootstrap-tagsinput.js"></script>
<script type="text/javascript">
$("input").val()
</script>
    </body>
    </html>
