node.js的函数问题 急求

function add(domanName,name,email,age,click){ var website=[]; website[0]=domainName; website[1]=name; website[2]=email; website[3]=age; website[4]=click; return website; } 急求这句话是什么意思呢? 是不是函数返回的结果,返回到数组里?这样函数add 的结果就跟数组建立了联系?


<div class="post-text" itemprop="text"> <p>I made a site that is user-based and so far I've been able to easily handle the sessions up to this point. I'm not a noob when it comes to php, but I don't have a good working knowledge of javascript. I have set a timeout for my users so that they are automatically timed out after 20 minutes of <em>inactivity</em>. It works great, other than they need to click a link or refresh in order for the session to actually be timed out. This is my current php timeout.</p> <pre><code>&lt;?php //TIMEOUT AFTER 20 MINUTES if(isset($_SESSION['signed_in'])) { $inactive = 1200; if(isset($_SESSION['timeout']) ) { $session_life = time() - $_SESSION['timeout']; if($session_life &gt; $inactive) { $id = $_SESSION['user_id']; //this db row is solely to display # of users logged in mysqli_query($connect, "UPDATE users SET user_signedin='0' WHERE user_id = '$id'"); session_destroy(); $_SESSION = array(); header("Location: timedout.php"); } } $_SESSION['timeout'] = time(); } ?&gt; </code></pre> <p>But I've also tried javascript (setting the timer to 5 minutes) like so:</p> <pre><code>&lt;script&gt; var wintimeout; function SetWinTimeout() { wintimeout = window.setTimeout("window.location.href='timedout.php';",300000); } $('body').click(function() { window.clearTimeout(wintimeout); //when user clicks remove timeout and reset it SetWinTimeout(); }); SetWinTimeout(); &lt;/script&gt; </code></pre> <p>I've searched a number of different places to find out how to implement an automatic redirect without having to click or refresh, but so far no luck. How do people redirect automatically (without clicking or refreshing) upon timeout?</p> <p><strong>EDIT:</strong> For people who are looking for the same answer: Ok, I was able to get the desired effect by adding this to my page header</p> <pre><code>&lt;?php if(isset($_SESSION['signed_in'])) { ?&gt; &lt;meta http-equiv="refresh" content="1800;url=internal.php" /&gt; ?&gt; </code></pre> <p>"internal.php" is very similar to the first piece of code I pasted above, though I've taken out the piece where it checks for timeout. However, now I'm having problems with people exiting the tab and not getting signed out, but that's a whole other issue. </p> </div>


<div class="post-text" itemprop="text"> <p>I am trying to make an auto-logout on inactivity using JavaScript. The thing is even when I move my mouse and rapidly press any key the timer does not reset.</p> <pre><code>var timeOut; function reset() { window.clearTimeout(timeOut); timeOut = window.setTimeout( "redir()" , 5000 ); } function redir() { window.location = "index.php?page=Logout"; } window.onload = function() { setTimeout("redir()" , 5000 ) }; window.onmousemove = reset; window.onkeypress = reset; </code></pre> </div>

CloseableHttpClient 4.5.2如何设置等待超时?

CloseableHttpClient 4.5.2中执行response = httpClient.execute(httpPost); 没有任何的等待效果,直接返回无连接,如果我想让他保持请求30秒是否可以? ``` RequestConfig defaultRequestConfig = RequestConfig.custom(). setConnectTimeout(30000).setConnectionRequestTimeout(30000) .setSocketTimeout(30000).build(); // CloseableHttpClient httpClient = HttpClients.createDefault(); CloseableHttpClient httpClient = HttpClients.custom().setDefaultRequestConfig(defaultRequestConfig).build(); CloseableHttpResponse response = null; String resultString = ""; HttpPost httpPost = new HttpPost(url); StringEntity entity = new StringEntity(json, ContentType.APPLICATION_JSON); httpPost.setEntity(entity); httpPost.setConfig(defaultRequestConfig); String uuid=UuidUtil.getuuid(); PgmsDao pgms=new PgmsDao(); LoginUI login=(LoginUI) FacesUtil.getSessionMapValue("loginUI"); String netid=login.getLdapuser().getNetid(); String request_user=login.getLdapuser().getName(); SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); String request_date = sdf.format(new Date()); Map<String,String> request_map=(Map)new JSONObject().fromObject(json); String action=request_map.get("action"); response = httpClient.execute(httpPost); resultString = EntityUtils.toString(response.getEntity(), "utf-8"); String response_date = sdf.format(new Date()); Map<String,String>result=(Map)new JSONObject().fromObject(resultString); String status=result.get("status"); ``` 如果是别的版本也可以,请大佬指点

jQuery Ajax事件绑定

<div class="post-text" itemprop="text"> <p>I am using the <a href="" rel="nofollow"></a> to produce a Mint style idle timer which performs an Ajax call to a 'keep-alive' page.</p> <p>I also have a piece of Javascript for Ajax form submits that pops up a 'Please wait' message to alert the user that activity is occurring though the pages isn't loading. </p> <p>For some reason the toggleAjaxLoader() function is getting bound to the ajax:before and ajax:complete events each time the keep alive page is polled. I do not want this as it is confusion to the user.

<div class="post-text" itemprop="text"> <p>I am trying to create a system where, when the user is inactive for x amount of time, they should are logged out and sent back to 'index.php'. I am using the code I found here - <a href="" rel="nofollow noreferrer"></a> and I put it in a function like this:</p> <p>phpfunc/inactivity.php</p> <pre><code>&lt;?php function inactivity() { // create a session if (!isset($_SESSION)) { session_start(); } // store the current time $now = time(); // get the time the session should have expired $limit = $now - 60*20; // check the time of the last activity if (isset ($_SESSION['last_activity']) &amp;&amp; $_SESSION['last_activity'] &lt; $limit) { // if too old, clear the session array and redirect $_SESSION = array(); header('../index.php'); exit; } else { // otherwise, set the value to the current time $_SESSION['last_activity'] = $now; } } ?&gt; </code></pre> <p>Then, I call the function like the top of my protected page </p> <p>templates/login_success.php:</p> <pre><code>&lt;?php require('/Users/Eamon/Sites/phpfunc/inactivity.php'); inactivity(); if($_SESSION['username'] === null){ header("location: ../index.php"); } ?&gt; &lt;h1&gt;Login Successful&lt;/h1&gt; &lt;h2&gt;Username: &lt;? echo $_SESSION['username']?&gt;&lt;/h2&gt; &lt;div id="logoutlinkdiv" &gt; &lt;a href = "#" &gt;Log out&lt;/a&gt; &lt;/div&gt; </code></pre> <p>I can login - and all the inactivity stuff seems to work. I tested it by adding a few echo statements here and there...and after login I tried going to the protected page - like this "localhost/~Eamon/templates/login_success.php" and it lets me see it...after 20 minutes I have to sign in again. However, I have a page that loads once the user logs out (after clicking the "logoutlinkdiv" link) - and it has a link on it to log in again. When I click this link, I get the message "Wrong Username or Password" - which can be found in the below file (which gets executed upon login). After 20 more minutes, I can login again without getting this error.</p> <p>checklogin.php</p> <pre><code>&lt;?php session_start(); $host="localhost"; // Host name $username="root"; // Mysql username $password="bonjour3"; // Mysql password $db_name="itit"; // Database name $tbl_name="members"; // Table name // Connect to server and select databse. $mysqli = new mysqli("$host", "$username", "$password", "$db_name")or die("cannot connect"); // Define $myusername and $mypassword $myusername=$_POST['myusername']; $mypassword=$_POST['mypassword']; $sql = $mysqli-&gt;prepare("SELECT * FROM $tbl_name WHERE username=? and password=?"); $sql-&gt;bind_param('ss',$myusername,$mypassword); $sql-&gt;execute(); $sql-&gt;store_result();//apply to prepare statement $numRows = $sql-&gt;num_rows; if($numRows === 1){ $_SESSION['username'] = $myusername; } else { echo "Wrong Username or Password"; session_destroy(); } ?&gt; </code></pre> <p>Here is the aforementioned logout page (where the user can login again...the trouble page!):</p> <p>templates/logout.php</p> <pre><code>&lt;?php session_start(); session_destroy(); ?&gt; &lt;div id="loginlinkdiv" &gt; &lt;h2&gt;You have been logged out.&lt;/h2&gt; &lt;a href = "#"&gt;Log in&lt;/a&gt; &lt;/div&gt; </code></pre> <p>In case it is is the jquery I am using.

When I click the login link (templates/logout.php) it brings me to index.php. I try to login, but the information in the textboxes gets reset, and seemingly nothin happens. When I try again - I get "Wrong Username or Password" again. Also - <code>&lt;? echo $_SESSION['username']?&gt;</code> is not showing up on the login_success.php page anymore.</p> <p><strong>UPDATE</strong></p> <p>It seems as if I'm not getting signed in because <code>&lt;? echo $_SESSION['username']?&gt;</code> still doesnt output anything.</p> </div>

今天给你们讲述一个外包程序员的幸福生活。男主是Z哥,不是在外包公司上班的那种,是一名自由职业者,接外包项目自己干。接下来讲的都是真人真事。 先给大家介绍一下男主,Z哥,老程序员,是我十多年前的老同事,技术大牛,当过CTO,也创过业。因为我俩都爱好喝酒、踢球,再加上住的距离不算远,所以一直也断断续续的联系着,我对Z哥的状况也有大概了解。 Z哥几年前创业失败,后来他开始干起了外包,利用自己的技术能...


场景 日常开发,if-else语句写的不少吧??当逻辑分支非常多的时候,if-else套了一层又一层,虽然业务功能倒是实现了,但是看起来是真的很不优雅,尤其是对于我这种有强迫症的程序"猿",看到这么多if-else,脑袋瓜子就嗡嗡的,总想着解锁新姿势:干掉过多的if-else!!!本文将介绍三板斧手段: 优先判断条件,条件不满足的,逻辑及时中断返回; 采用策略模式+工厂模式; 结合注解,锦...

离职半年了,老东家又发 offer,回不回?

有小伙伴问松哥这个问题,他在上海某公司,在离职了几个月后,前公司的领导联系到他,希望他能够返聘回去,他很纠结要不要回去? 俗话说好马不吃回头草,但是这个小伙伴既然感到纠结了,我觉得至少说明了两个问题:1.曾经的公司还不错;2.现在的日子也不是很如意。否则应该就不会纠结了。 老实说,松哥之前也有过类似的经历,今天就来和小伙伴们聊聊回头草到底吃不吃。 首先一个基本观点,就是离职了也没必要和老东家弄的苦...

不知道是不是只有我这样子,还是你们也有过类似的经历。 上学的时候总有很多光辉历史,学年名列前茅,或者单科目大佬,但是虽然慢慢地长大了,你开始懈怠了,开始废掉了。。。 什么?你说不知道具体的情况是怎么样的? 我来告诉你: 你常常潜意识里或者心理觉得,自己真正的生活或者奋斗还没有开始。总是幻想着自己还拥有大把时间,还有无限的可能,自己还能逆风翻盘,只不是自己还没开始罢了,自己以后肯定会变得特别厉害...






当HR压你价,说你只值7K时,你可以流畅地回答,记住,是流畅,不能犹豫。 礼貌地说:“7K是吗?了解了。嗯~其实我对贵司的面试官印象很好。只不过,现在我的手头上已经有一份11K的offer。来面试,主要也是自己对贵司挺有兴趣的,所以过来看看……”(未完) 这段话主要是陪HR互诈的同时,从公司兴趣,公司职员印象上,都给予对方正面的肯定,既能提升HR的好感度,又能让谈判气氛融洽,为后面的发挥留足空间。...

硅谷科技公司上班时间OPEN早已不是什么新鲜事,早九晚五是常态,但有很多企业由于不打卡,员工们10点、11点才“姗姗来迟”的情况也屡见不鲜。 这种灵活的考勤制度为人羡慕,甚至近年来,国内某些互联网企业也纷纷效仿。不过,硅谷普遍弹性的上班制度是怎么由来的呢?这种“流行性迟到”真的有那么轻松、悠哉吗? 《动态规划专题班》 课程试听内容: 动态规划的解题要领 动态规划三大类 求最值/计数/可行性 常...






爬取彼岸桌面网站较为简单,用到了requests、lxml、Beautiful Soup4


编程语言层出不穷,从最初的机器语言到如今2500种以上的高级语言,程序员们大呼“学到头秃”。程序员一边面临编程语言不断推陈出新,一边面临由于许多代码已存在,程序员编写新应用程序时存在重复“搬砖”的现象。 无代码/低代码编程应运而生。无代码/低代码是一种创建应用的方法,它可以让开发者使用最少的编码知识来快速开发应用程序。开发者通过图形界面中,可视化建模来组装和配置应用程序。这样一来,开发者直...

前几天我们公司做了一件蠢事,非常非常愚蠢的事情。我原以为从学校出来之后,除了找工作有测试外,不会有任何与考试有关的事儿。 但是,天有不测风云,公司技术总监、人事总监两位大佬突然降临到我们事业线,叫上我老大,给我们组织了一场别开生面的“考试”。 那是一个风和日丽的下午,我翘着二郎腿,左手端着一杯卡布奇诺,右手抓着我的罗技鼠标,滚动着轮轴,穿梭在头条热点之间。 “淡黄的长裙~蓬松的头发...
