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');
    });
});

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

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

试试这个，在我的应用程序开发…我还遇到了一个麻烦，模型属性的默认值=> data-keyboard="true"， => data- background ="非静态"

希望这对你有所帮助!

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。

TLDR

背景:‘静态’

为背景指定静态，它不会在单击时关闭模式。

你也可以不使用JQuery做到这一点，如下所示:

<div id="myModal">

var modal = document.getElementById('myModal');
modal.backdrop = "static";
modal.keyboard = false;
