错误：在初始化之前无法调用对话框上的方法;试图调用方法'关闭'

Question

继续调用方法错误，不知道还有什么可以尝试。我有这个在另一个程序中工作，但不在ajax函数内。我试过靠近'关闭'，“关闭”，但仍然没有运气。当用户在对话框模式外单击它将关闭当前打开模态时尝试创建它。

function viewForm(record_id) {
    $.ajax({
        type: "POST",
        url: "/info_notifications/fetch_pending_changes",
        data: "_unique_id=" + record_id,
        success: function (msg) {
            document.getElementById('dialog').innerHTML = msg;
            var closedialog;
        function overlayclickclose() {
            if (closedialog) {
                $('#dialog').dialog('close'); //<--this is the method its attempting to call
            }

            //set to one because click on dialog box sets to zero 
            closedialog = 1;
        }
        $('#open').click(function () {
            $('#dialog').dialog("open");
            closedialog = 0;
        });

        $("#dialog").dialog({
            resizable: true,

            width: 'auto',
            height: 'auto',
            open: function () {
                closedialog = 1;
                $(document).bind('click', overlayclickclose);
            },
            focus: function () {
                closedialog = 0;
            },
            close: function () {
                $(document).unbind('click');
            },
            closeText: "Close",
            buttons: {
                "Update": function () {
                    $.ajax({
                        type: "POST",
                        url: "/info_notifications/update_notification",
                        data: "_unique_id=" + record_id,
                        success: function (msg) {
                            $(document).ajaxStop(function () {
                                location.reload(true);
                            });
                        }
                    });
                },
                "Approve": function () {
                    $.ajax({
                        type: "POST",

                        success: function (msg) {
                            $(document).ajaxStop(function () {
                                location.reload(true);
                            });
                        }
                    });
                },
                "Deny": function () {
                    $.ajax({

                    click: $(this).dialog("close");
