Question

我曾尝试过引导模态，但其按钮不起作用。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>

Answer 1

您当前没有类.或标识符#符号的选择器（“ quit_Modal”和'btnClose'）将引用标签，因此jQuery将搜索名称为{{1 }}和<quit_Modal>在您的DOM中。

您缺少选择器符号（点<btnClose>和.）：

注意：：$("#quit_Modal").modal('show'); $('.btnClose').trigger('click');应该是ID quit_Modal。

id="quit_Modal"

jQuery(document).ready(function(e) {
  $("#quit_Modal").modal('show');

  setTimeout(function() {
    $('.btnClose').trigger('click');
  }, 1000);
});

Answer 2

您的选择器错误。

代替：

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

使用此：

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

Answer 3

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

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

两者都是类，因此请先在其之前放置点（。）...

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

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

单击按钮后，引导模态不起作用
