您可以使用下面的代码

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

更改默认行为。

如果你需要关闭外面的点击，但允许按下退出

$('#myModal').modal({
    backdrop: 'static',   // This disable for click outside event
    keyboard: true        // This for keyboard event
})

<button class="btn btn-primary btn-lg" data-backdrop="static" data-keyboard="false" data-target="#myModal" data-toggle="modal">

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

下面的脚本适合我:

// prevent event when the modal is about to hide
$('#myModal').on('hide.bs.modal', function (e) {
    e.preventDefault();
    e.stopPropagation();
    return false;
});

<button class='btn btn-danger fa fa-trash' data-toggle='modal' data-target='#deleteModal' data-backdrop='static' data-keyboard='false'></button>

只需将数据背景和数据键盘属性添加到打开的模型上的按钮。
