无法关闭淡入淡出的引导模式

我正在使用以下代码动态生成模式弹出窗口,但遇到了一个问题。问题是模式显示正确,但我无法关闭它。我都试过了 data-dismiss="modal" 和 .modal("hide") 无济于事。我检查过按钮单击事件是否被触发,唯一的问题是模式没有关闭。

JS

// Requires jQuery
var dialogHelper = new dialog();

function dialog() {
    /* Bootstrap Modal Dialog
    *  Displays message from parameter
    */
    this.ShowModalDialog = function (message, title, buttons) {
        var dialogMessage = "";
        var dialogTitle = "System Message";
        var dialogButtons = [];

        if (message)
            dialogMessage = message;
        if (title)
            dialogTitle = title;
        if (buttons) {
            dialogButtons = buttons;
        }

        var id = randomString(10);

        jQuery("<div/>", {
            id: id,
            class: "modal fade",
            // href: 'http://google.com',
            //title: title,
            //rel: 'external',
            //text: message
        })
            .attr("tabindex", "-1")
            .attr("role", "dialog")
            .attr("aria-labelledby", id + "Label")
            .attr("aria-hidden", true)
            .attr("data-backdrop", "static")
            .attr("data-keyboard", false)
            .load("/Static/BootstrapDialogTemplate.html", function () {
                $("#" + id + " .modal-title")
                    .attr("id", id + "Label")
                    .text(dialogTitle);
                $("#" + id + " .modal-body").text(dialogMessage);

                var footer = $("#" + id + " .modal-footer");

                dialogButtons.forEach(function (element) {
                    $('<button/>', {
                        text: element.Text,
                        click: function () {
                            if (element.Event) {
                                element.Event();
                            }
                        },
                        class: element.Class
                    })
                        .attr("data-dismiss", "modal")
                        .appendTo(footer);
                });
            })
            .appendTo(document.body)
            .modal("show");
    };
};

/* Automatically destroy modal on close */
$(".modal").on('hidden.bs.modal', function () {
    $(this).data('bs.modal', null);
});

function randomString(length) {
    var chars = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXTZabcdefghiklmnopqrstuvwxyz";
    var string_length = length;
    var randomstring = '';

    for (var i = 0; i < string_length; i++) {
        var rnum = Math.floor(Math.random() * chars.length);
        randomstring += chars.substring(rnum, rnum + 1);
    }

    return randomstring;
};

/静态/bootstrapdialogtemplate.html

<div class="modal-dialog" role="document">
    <div class="modal-content">
        <div class="modal-header">
            <h5 class="modal-title"></h5>
            <button type="button" class="close" data-dismiss="modal" aria-label="Close">
                <span aria-hidden="true">&times;</span>
            </button>
        </div>
        <div class="modal-body">
        </div>
        <div class="modal-footer">
        </div>
    </div>
</div>

样本调用

dialogHelper.ShowModalDialog("Are you sure you want to create this item?", null, [{
        Text: "Yes",
        Event: function () { alert("YES!"); },
        Class: "btn btn-primary"
    }, {
        Text: "No",
        Event: function () { },
        Class: "btn btn-secondary"
    }]);

样本输出

<div id="2tF5r5mecT" class="modal fade show" tabindex="-1" role="dialog" aria-labelledby="2tF5r5mecTLabel" data-backdrop="static" data-keyboard="false" aria-modal="true" style="display: block;">
    <div class="modal-dialog" role="document">
        <div class="modal-content">
            <div class="modal-header">
                <h5 class="modal-title" id="2tF5r5mecTLabel">System Message</h5>
                <button type="button" class="close" data-dismiss="modal" aria-label="Close">
                    <span aria-hidden="true">×</span>
                </button>
            </div>
            <div class="modal-body">Are you sure you want to create this item?</div>
            <div class="modal-footer">
            <button class="btn btn-primary" data-dismiss="modal">Yes</button><button class="btn btn-secondary" data-dismiss="modal">No</button></div>
        </div>
    </div>
</div>
<div class="modal-backdrop fade show"></div>

通过随机测试,我成功地推断出 fade 类在生成模式时允许关闭它而不进行任何其他更改。

从

jQuery("<div/>", {
        id: id,
        class: "modal fade",
        // href: 'http://google.com',
        //title: title,
        //rel: 'external',
        //text: message
    })

到

jQuery("<div/>", {
        id: id,
        class: "modal",
        // href: 'http://google.com',
        //title: title,
        //rel: 'external',
        //text: message
    })

我的代码可以工作,但没有衰减效果。我已经检查了所有自定义的CSS .fade 但我没有。当问题持续存在时,浏览器上没有控制台错误。你们中有人遇到过这个问题吗?我刚升级到jquery 3.3.1和bootstrap 4.2.1。当没有褪色效果的时候感觉很奇怪。
