You can Disallow closing of #signUp (This should be the id of the modal) modal when clicking outside of modal.
As well as on ESC button.
jQuery('#signUp').on('shown.bs.modal', function() {
    jQuery(this).data('bs.modal').options.backdrop = 'static';// For outside click of modal.
    jQuery(this).data('bs.modal').options.keyboard = false;// For ESC button.
})

把这段代码放在modal html的第一个块中

引导4.倍

-keyboard = "和"日期-backdrop =“静态”

Boostrap 5.倍

data-bs-keyboard = " false " data-bs-backdrop =“静态”

例子:

<div id="modal-user" class="modal fade" tabindex="-1" role="dialog" aria-hidden="true" data-bs-keyboard="false" data-bs-backdrop="static">

文档引导5:https://getbootstrap.com/docs/5.1/components/modal/#options

包括一个情态背景元素。或者，为背景指定静态，它不会在单击时关闭模式。

我缺少情态对话框，这就是为什么我的关闭情态不能正常工作。

试试这个:

<div
  class="modal fade"
  id="customer_bill_gen"
  data-keyboard="false"
  data-backdrop="static"
>

在我的应用程序中，我使用下面的代码通过jQuery显示Bootstrap模态。

 $('#myModall').modal({
                        backdrop: 'static',
                        keyboard: true, 
                        show: true
                });
