如何在jquery-dialogextend中加载ajax

Question

我正在尝试开发一个应用程序，用户可以在单击按钮的弹出窗口中选择日期并查看其事务历史记录，然后将调用ajax并返回然后返回pop内部。参考：http://romb.github.io/jquery-dialogextend/example.html

 <script>
        $(function () {
            var remoteUrl = 'send.php';
            var largeParams = {
                param1: $("#date").val()
            };
            $("#button").click(function () {
                var dialogBox = {
                    "title": "Dialog title",
                    "width": 640,
                    "height": 480,
                    "modal": true,
                    "resizable": true,
                    "draggable": true,
                    "dialogClass": "ui-dialog-red",
                    "open": function () {
                        var $message = $('<div>Loading...</div>');
                        $.ajax({
                            url: remoteUrl,
                            type: 'POST',
                            data: largeParams,
                            context: {
                                jDialongbox: dialogRef
                            },
                            success: function (content) {
                                this.jDialongbox.setMessage(content);
                            }
                        });

                        return $message;
                    },
                    "buttons": {"Close": function () {
                            $(this).dialog("close");
                        }}
                };
                var moreOptions = {
                    "closable": true,
                    "maximizable": true,
                    "minimizable": true,
                    "dblclick": "collapse",
                    "minimizeLocation": "left",
                    "icons": {
                        "close": "ui-icon-close",
                        "maximize": "ui-icon-arrow-4-diag",
                        "minimize": "ui-icon-arrowstop-1-s",
                        "restore": "ui-icon-carat-2-n-s"
                    }
                };
                $("#form").dialog(dialogBox).dialogExtend(moreOptions);
            });
        });
    </script>
