你可以像这样使用一个属性:data- background ="static"或者使用javascript:

$('#myModal').modal({
    backdrop: 'static',
    keyboard: false  // to prevent closing with Esc button (if you want this too)
})

也可以看到这个答案:禁止twitter引导模式窗口关闭

将此CSS用于模态和模态对话框

.modal{
    pointer-events: none;
}

.modal-dialog{
    pointer-events: all;
 }

这可以解决您在Modal中的问题

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.
})

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

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;

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
