javascript - 单击按钮后引导模式不起作用

我尝试过引导模式，但它的按钮不起作用。请帮忙谢谢你

我的代码不起作用:

  <body>
    <div class="quit_modal" tabindex="-1" role="dialog" data-toggle="modal" data-target="quit_model">
  <div class="modal-dialog" id="delete-file-modal" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title">Modal title</h5>
        <button type="button" class="btnClose" data-dismiss="modal" aria-label="Close">
          <span aria-hidden="true">&times;</span>
        </button>
      </div>
      <div class="modal-body">
        <div class="container-fluid">
            <div class="row">
                <div class="col-md-4 ml-2"></div>
                    <button type="button" class="btn btn-secondary"><a id="close" data-dismiss="modal" data-target="#quit_modal">Close</a></button>&nbsp;&nbsp;
                     <button type="button" class="btn btn-danger">Button</button>
            </div>
        </div>
      </div>

    $("quit_Modal").modal('show');

     $('btnClose').trigger('click');

最佳答案

您当前的选择器(“quit_Modal”和“btnClose”)没有类 .或标识符#标志将引用标签，因此 jQuery 将搜索名称为 <quit_Modal> 的标签。和<btnClose>在你的 DOM 中。

您缺少选择器符号(点 . 和 # ):

$("#quit_Modal").modal('show');
$('.btnClose').trigger('click');

注意:quit_Modal应该是一个ID id="quit_Modal" .

jQuery(document).ready(function(e) {
  $("#quit_Modal").modal('show');

  setTimeout(function() {
    $('.btnClose').trigger('click');
  }, 1000);
});

        <h4 class="modal-title" id="myModalLabel">Modal title</h4>

      <div class="modal-body">

      <div class="modal-footer">
        <button type="button" class="btn btn-default btnClose" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-danger">Button</button>
