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。

你可以使用

$.fn.modal.prototype.constructor.Constructor.DEFAULTS.backdrop = 'static';
$.fn.modal.prototype.constructor.Constructor.DEFAULTS.keyboard =  false;

更改默认行为。

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.
})

对我来说有效的解决方法如下:

$('#myModal').modal({backdrop: 'static', keyboard: false})  

背景:禁用点击外部事件

键盘:禁用scape关键字事件

如果你不知道模式是否已经打开或者还没有打开，你需要配置模式选项，还有一个选项:

引导3.4

var $modal = $('#modal');
var keyboard = false; // Prevent to close by ESC
var backdrop = 'static'; // Prevent to close on click outside the modal

if(typeof $modal.data('bs.modal') === 'undefined') { // Modal did not open yet
    $modal.modal({
        keyboard: keyboard,
        backdrop: backdrop
    });
} else { // Modal has already been opened
    $modal.data('bs.modal').options.keyboard = keyboard;
    $modal.data('bs.modal').options.backdrop = backdrop;

    if(keyboard === false) { 
        $modal.off('keydown.dismiss.bs.modal'); // Disable ESC
    } else { // 
        $modal.data('bs.modal').escape(); // Resets ESC
    }
}

引导 4.3+

var $modal = $('#modal');
var keyboard = false; // Prevent to close by ESC
var backdrop = 'static'; // Prevent to close on click outside the modal

if(typeof $modal.data('bs.modal') === 'undefined') { // Modal did not open yet
    $modal.modal({
        keyboard: keyboard,
        backdrop: backdrop
    });
} else { // Modal has already been opened
    $modal.data('bs.modal')._config.keyboard = keyboard;
    $modal.data('bs.modal')._config.backdrop = backdrop;

    if(keyboard === false) { 
        $modal.off('keydown.dismiss.bs.modal'); // Disable ESC
    } else { // 
        $modal.data('bs.modal').escape(); // Resets ESC
    }
}

将选项更改为_config

如果你想禁用所有使用jQuery的模态的外部点击，使用这个。在jQuery之后添加这个脚本到你的Javascript。

jQuery(document).ready(function () {
    jQuery('[data-toggle="modal"]').each(function () {
       jQuery(this).attr('data-backdrop','static');
       jQuery(this).attr('data-keyboard','false');
    });
});
