  • error on connecting to the server : socket io is not defined

    - by max
    i know there's been couple of question about the same problem , i've already check them . i have very simple node.js chat app i have a server running on 8000 port and it works fine my client pages are html , they are running on apache and i'm using socket.io to connect them to the server and it works fine on the local host but when i upload the app on the server i keep on getting this error in the firebug io is not defined var socket = io.connect('http://atenak.com:8000/'); or sometimes it doesn't show that but when i try to broadcast message from cliend i get this error : socket is undefined socket.emit('msg', { data: msg , user:'max' }); the only difference is i've changed the localhost with atenak.com ! here is my html code var socket = io.connect('http://atenak.com:8000/'); var user = 'jack'; socket.on('newmsg', function (data) { if(data.user == user ) { $('#container').html(data.data); } }); function brodcast(){ var msg = $('#fild').val(); socket.emit('msg', { data: msg , user:'max' }); } </script> </head> <body> <div id="container"> </div> <input id="fild" type="text"> <input name="" type="button" onClick="brodcast();"> </body> i have included the sockt.io.js and server is running ok which means socket.io is installed on the server here is the live page http://atenak.com/client.html

  • EKCalendar not added to iCal

  • Is it possible to write map/reduce jobs for Amazon Elastic MapReduce using .NET?

    - by Chris
    Is it possible to write map/reduce jobs for Amazon Elastic MapReduce (http://aws.amazon.com/elasticmapreduce/) using .NET languages? In particular I would like to use C#. Preliminary research suggests not. The above URL's marketing text suggests you have a "choice of Java, Ruby, Perl, Python, PHP, R, or C++", without mentioning .NET languages. This Amazon thread (http://developer.amazonwebservices.com/connect/thread.jspa?messageID=136051 -- "Support for C# / F# map/reducers") explicitly says that "currently Amazon Elastic MapReduce does not support Mono platform or languages such as C# or F#." The above suggests that it can't be done. I'm wondering if there are any workarounds, though. For example, can I modify the Elastic MapReduce machine image for my account, and install Mono on there? An alternative, suggested by Amazon FAQs "Using Other Software Required by Your Jar" (http://docs.amazonwebservices.com/ElasticMapReduce/latest/DeveloperGuide/index.html?CHAP_AdvancedTopics.html) and "How to Use Additional Files and Libraries With the Mapper or Reducer" (http://docs.amazonwebservices.com/ElasticMapReduce/latest/DeveloperGuide/index.html?addl_files.html), is to make the first step of the Map/Reduce job be to install Mono on the local instance. That sounds kind of inefficient, but maybe it could work? Maybe a saner alternative would be to try to forgo the convenience of Elastic MapReduce, and manually set up my own Hadoop cluster on EC2. Then I assume I could install Mono without difficulty.

  • django - variable declared in base project does not appear in app

    - by unsorted
    I have a variable called STATIC_URL, declared in settings.py in my base project: STATIC_URL = '/site_media/static/' This is used, for example, in my site_base.html, which links to CSS files as follows: <link rel="stylesheet" href="{{ STATIC_URL }}css/site_tabs.css" /> I have a bunch of templates related to different apps which extend site_base.html, and when I look at them in my browser the CSS is linked correctly as <link rel="stylesheet" href="/site_media/static/css/site_tabs.css" /> (These came with a default pinax distribution.) I created a new app called 'courses' which lives in the ...../apps/courses folder. I have a view for one of the pages in courses called courseinstance.html which extends site_base.html just like the other ones. However, when this one renders in my browser it comes out as <link rel="stylesheet" href="css/site_tabs.css" /> as if STATIC_URL were equal to "" for this app. Do I have to make some sort of declaration to get my app to take on the same variable values as the project? I don't have a settings.py file for the app. by the way, the app is listed in my list of INSTALLED_APPS and it gets served up fine, just without the link to the CSS file (so the page looks funny). Thanks in advance for your help.

  • Having to hit the site login button twice after first turning on computer

    - by John
    Hello, The code below is for a login that I'm using. It works fine, but when I first try logging in after turning on my computer, it only works the second time that I hit the "Login" button. Any idea how I can make it not require hitting the "Login" button twice in this situation?

  • Focus behavior in Applet-Javascript interaction

    - by Dan
    I have a web page with an applet that opens a popup window and also makes Javascript calls. When that Javascript call results in a focus() call on an HTML input, that causes the browser window to push itself in front of the applet window. But only on certain browsers, namely MSIE. On Firefox the applet window remains on top. How can I keep that behavior consistent in MSIE? Note that using the old Microsoft VM for Java also achieves the desired (applet window in front) result. HTML code: <html> <head> <script type="text/javascript"> function focusMe() { document.getElementById('mytext').focus(); } </script> </head> <body> <applet id="myapplet" mayscript code="Popup.class" ></applet> <form> <input type="text" id="mytext"> <input type="button" onclick="document.getElementById('myapplet').showPopup()" value="click"> </form> </body> </html> Java code: public class Popup extends Applet { Frame frame; public void start() { frame = new Frame("Test Frame"); frame.setLayout(new BorderLayout()); Button button = new Button("Push Me"); frame.add("Center", button); button.addActionListener(new ActionListener(){ public void actionPerformed(ActionEvent e) { frame.setVisible(false); } }); frame.pack(); } public void showPopup() { frame.setVisible(true); JSObject.getWindow(this).eval("focusMe()"); } }

  • jQuery slider vanishes after container div is toggled

    - by Shahar Evron
    I have a page which contains a jQuery-UI horizontal slider, created using a little function, inside a DIV which can be displayed / hidden by clicking on it's title, using $.toggle(). Problem is, once the div is hidden, when it is expanded the slider is gone. A simplified demo of the problem can be seen here: http://arr.gr/jquery-issue.html (file contains all relevant source code) - when clicking the "Advanced Options" title to hide and then show the div, the slider is no longer there. Any suggestions on how to work around this?

  • Iframe form not submittin in IE but working in Firefox

    - by Younes
    I have got a form that posts values to a page in a wizard. When i'm loading this form in a Iframe everything is working fine in Firefox, it will get me to the second step of the wizard and maintains the values i filled in. When im testing this in Internet Explorer i am not getting to the second step, instead of that it returns me to the first step of the wizard with all fields being blank. When i check this in Fiddler i see that im getting a different response when i'm posting the form in the Iframe from Firefox compared to Internet Explorer. How can i make this work for all browsers? What am I doing wrong? This is what i get back from Fiddler: Firefox Post: Ressult Protocol Host URL Body Caching Content-Type Process Comments Custom 1 302 HTTP www.dmg.eu /brugman/budgetplanner/aanmelden.php 0 no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Expires: Thu, 19 Nov 1981 08:52:00 GMT text/html; charset=UTF-8 firefox:6116 Get: # Result Protocol Host URL Body Caching Content-Type Process Comments Custom 2 200 HTTP www.dmg.eu /brugman/budgetplanner/ 40.677 no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Expires: Thu, 19 Nov 1981 08:52:00 GMT text/html; charset=UTF-8 firefox:6116 Internet Explorer Post: Result Protocol Host URL Body Caching Content-Type Process Comments Custom 73 302 HTTP www.dmg.eu /brugman/budgetplanner/aanmelden.php 0 no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Expires: Thu, 19 Nov 1981 08:52:00 GMT text/html; charset=UTF-8 iexplore:536 Get: Result Protocol Host URL Body Caching Content-Type Process Comments Custom 74 302 HTTP www.dmg.eu /brugman/budgetplanner/ 0 no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Expires: Thu, 19 Nov 1981 08:52:00 GMT text/html; charset=UTF-8 iexplore:536 Hope someone knows what the diff is :).

  • navigator.onLine

    I'm playing with the incomplete example found at http://www.w3.org/TR/offline-webapps/ But I'm distressed to see comments in it like: "renders the note somewhere", and "report error", and "// …" So, will someone please help me write a valid example?

  • Linq-to-Entities Left JOIN

    - by shivesh
    This is my query: from forum in Forums join post in Posts on forum equals post.Forum into postGroup from p in postGroup where p.ParentPostID==0 select new { forum.Title, forum.ForumID, LastPostTitle = p.Title, LastPostAddedDate = p.AddedDate }).OrderBy(o=>o.ForumID) Currently the Join is not left join, meaning if some forum doesn't have a post that belongs to it, it will not be returned. The forum without posts must be returned with null (or default) values for the post properties.

  • prevent javascript in the WMD editor's preview box

    - by Justin Grant
    There are many SO questions (e.g. here and here) about how to do server-side scrubbing of Markdown produced by the WMD editor to ensure the HTML generated doesn't contain malicious script, like this: <img onload="alert('haha');" src="http://www.google.com/intl/en_ALL/images/srpr/logo1w.png" /> Unfortunately, this still allows script to show up in the WMD client's preview box. I doubt this is a big deal since if you're scrubbing the HTML on the server, an attacker can't save the bad HTML so no one else will be able to see it later and have their cookies stolen or sessions hijacked by the bad script. But it's still kinda odd to allow an attacker to run any script in the context of your site, and it's probably a bad idea to allow the client preview window to allow different HTML than your server will allow. StackOverflow has clearly plugged this hole. How did they do it? [NOTE: I already figured this out but it required some tricky javascript debugging, so I'm answering my own question here to help others who may want to do ths same thing]

  • Play youtube video in full screen ?

    - by Madhup
    Hi all, First of all sorry, If somebody finds this question is repeated (haven't found any by myself). I am developing for an iPad application and trying to play youtube videos using this code: NSString *embedHTML = @"\ <html><head>\ <style type=\"text/css\">\ body {\ background-color: transparent;\ color: white;\ }\ </style>\ </head><body style=\"margin:0\">\ <embed id=\"yt\" src=\"%@\" type=\"application/x-shockwave-flash\" \ width=\"%0.0f\" height=\"%0.0f\"></embed>\ </body></html>"; NSString *html = [NSString stringWithFormat:embedHTML, youTubeUrl, 142.0, 129.5]; [wbView loadHTMLString:html baseURL:nil]; The code works fine when used in an iphone application (i.e. you touch on the webview and it starts playing the youtube video in fullscreen.) But when used in the iPad, on clicking the web view it starts playing the video in the web view itself and shows options to go to full screen, while I want to start the playback in the full screen from the beginning, like it does in the iPhone. Anybody having some ideas or people who have done it before please help. Thanks, Madhup

I have something like this in my main.html: <ngInclude src="partial.html"> </ngInclude> And my partial.html has something like this <h2> heading 1 <h2> <script type="text/javascript" src="static/js/partial.js"> </script> And my partial.js has nothing to do with angularjs. nginclude works and I can see the html, but I can not see the javascript file being loaded at all. I know how to use firebug/ chrome-dev-tool, but I can not even see the network request being made. What am I doing wrong? I knwo angular has some special meaning to script tag. Can I override it?
