Question

我有一个会话超时脚本，现在已成功运行在我的网站上。该脚本来自http://www.jensbits.com/2010/04/18/coldfusion-session-timeout-with-warning-and-session-refresh/

突然间，它抛出了以下错误：

未捕获错误：在初始化之前无法调用对话框上的方法;尝试调用方法＆＃39;打开

这是我的剧本：

<script type="text/javascript" language="javascript">
$(function(){              
        // jQuery UI Dialog    
        $('#dialogWarning').dialog({
            autoOpen: false,
            width: 400,
            modal: true,
            resizable: false,
            buttons: {
                "Restart Session": function() {
                    //reset session on server
                    $.post("restart_session.cfm");

                    //reset the variables
                    requestTime = new Date();
                    warningStarted = false;
                    countdownTime = warning;

                    //clear current checkSessionTimeEvent and start a new one

                }

function countdownTicker()

    $("span#dialogText-warning").html(countdownTime);
    //decrement countdownTime
    countdownTime--;

我正在运行以下JQuery版本：

我有类似的问题。它始于jQuery 1.11.0。回滚到jQuery v1.8.2并解决问题

JQuery - 在初始化之前无法在对话框上调用方法;
