  • How do I include the proper XML / HTML definitions in a file generated by XSL?

    - by Colen
    As I understand it, you need to include the following code at the top of your HTML files to make sure they're parsed properly: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"> ... I'm generating an html file by transforming an XML file using an XSL file. This is going to be done using the MSXML tool, which produces a standard HTML file as output. If I just do this: <xsl:template match="/"> <html> ... Everything is fine. But if I do this: <xsl:template match="/"> <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"> ... I get the error XML Parsing Error: XML or text declaration not at start of entity in Firefox, or Cannot have a DOCTYPE declaration outside of a prolog. in IE. Presumably this is because the parser is finding two How do I make the browser a) understand that I am using proper strict HTML, and b) make sure those declarations are put into the HTML output file that MSXML generates?

  • "Downloading" a computed value form JavaScript

    - by Travis Jensen
    I'm hoping you can prove me wrong here (please, please, please! ;). I have a situation where I need to download encrypted data from a Server D (for "Data"). Server K (for "Key") has the encryption key. For security sake, I would really prefer that Server D never know the key that Server K knows. What I want is my client (e.g. your browser) to connect to Server D for the data and Server K for the key and doe the decryption locally so the unencrypted stuff never leaves your computer. I can do this fine for text areas in the dom by replacing the contents of the HTML. However, sometimes, I would like to do larger files that I stream to the file system. For instance, perhaps I want to encrypt a movie and decrypt it and stream the contents to the my video player. I am not a JavaScript guru by any stretch, especially when it comes to the edge cases of things like the security sandbox. For Small D, I can handle the decryption, but I don't know how to save the decrypted file. Large D seems problematic as memory runs out. Anybody have any ideas that don't involve native plugins? Thanks!

  • Our Flash Streaming Player Occasionally Stutters like a Skipping CD after a Period of Time

    - by Jonathan Fritz
    We offer a streaming player for a number of our clients, who are responsible for their providing us with their own audio streams. We have written a very simple flash player that can play all of the streams that we support (icecast/shoutcast/live365/mp3 over http/etc). Unfortunately, we have found that when listening, our player sometimes begins to stutter (like a skipping cd), sometimes after only 10 minutes, and sometimes after an hour of listening. We have noticed this behaviour in firefox on both linux and windows. Does anybody know anything about this problem? We know that flash isn't ideal for infinite streams of audio, but it's about all that we can find that's on every platform out there. If anybody can suggest a solution to our problem, I'll be your friend forever. Here is a link to the live player: http://cr-jf.jfritz.02.dev.wecreate.com/streaming/player_v5/ Note that you'll need to test in a browser that isn't IE, because we use WMP in IE, and that the JavaScript on the page will cause the player to unload and re-load once an hour because of memory issues. Because I can only put one hyperlink in a post, I'll add a link to the player source code as a comment. Thanks all!

  • using mod-rewrite to redirect requests for jquery.js to GoogleAPI cache

    - by Aditya Advani
    Hi All, Our Linux server with Apache 2.x, Plesk 8.x hosts a number of e-commerce websites. To take advantage of browser caching we would like to use Google's provided copy of jquery.js. Hence in the vhost.conf file of each we can use the following RewriteRule RewriteCond %{REQUEST_FILENAME} jquery.min.js [nc] RewriteRule . http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js [L] And in vhost_ssl.conf RewriteCond %{REQUEST_FILENAME} jquery.min.js [nc] RewriteRule . https://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js [L] OK now these rules work fine in the individual vhost.conf files of each domain. However we host over 200 domains, I would like for them to work but cannot seem to get them to work globally in the httpd.conf file. Challenges are the following: Get the rewriterule to work in httpd.conf Detect if HTTPS is on, and if it is and the is is a secure page, rewrite to ... Each individual domain will still have it's own custom mod-rewrite rules. Which rules take precedence - global or per-domain? Do they combine? Is it ok if I have the "RewriteEngine On" directive in the global httpd.conf and then again in the vhost.conf? Please let me know what your guys' suggestions are. Desperate for a solution to this problem.

  • HTMLInputElement in IE7

    - by Vladislav Qulin
    I'm writing an extension for crossbrowser input&textarea selection getter and setter. So that's the way i write my code: HTMLInputElement.prototype.getSelectionRange = get_selection_range; HTMLInputElement.prototype.setSelection = set_selection_range; HTMLTextAreaElement.prototype.getSelectionRange = get_selection_range; HTMLTextAreaElement.prototype.setSelection = set_selection_range; get_selection_range and set_selection_range are those extended functions. So i just wanted to replace someInputElement.selectionStart = a; // and whole lot of code due to browser someInputElement.selectionEnd = b; // compatibility with just someInputElement.setSelection(a, b); someInputElement.setSelection({ start: a, end: b }); someOtherElement.setSelection(someInputElement.getSelection()); But then i met couple of difficulties in IE7. First of all, IE7 doesnt know what is HTMLInputElement. I don't want to extend whole Object. Well, that would be the last thing i'll do, but i want to evade it. Functions get_selection_range and set_selection_range are alright, don't ask what's within, you've seen it couple of times already. So the question is: is there any legit substitution for HTMLInputElement in JS for IE7?

  • Facebook Application with PHP running loosing session

    - by ArneRie
    Iam trying to build an Facebook Application based on PHP. The Application is running under php on my own Webhost inside an Canvas as iFrame. I have included the newest Client Library for PHP from Facebook: facebook-php-sdk-94fcb13 To Authorize the user inside my application iam trying to use Facebook Connect, like the example shipped with the Client. Everything works fine the 1st Login, but when i hit the F5 Key to reload the page, the session is lost and i have to login again. When i call my application outside of the Facebook Canvas everything is fine. Iam not sure, but i think my Browser (Chrome/FireFox - Ubuntu) is not allowing to store an cookie inside an iFrame. Does someone knows an solution for this Problem? Here are some Parts of the Sourcecode: $facebook = new Facebook(array( 'appId' => 'x', 'secret' => 'x', 'cookie' => 'true', )); $session = $facebook->getSession(); $facebook->setSession($session); $me = null; // Session based API call. if ($session) { try { $uid = $facebook->getUser(); $me = $facebook->api('/me'); } catch (FacebookApiException $e) { error_log($e); } } // login or logout url will be needed depending on current user state. if ($me) { $logoutUrl = $facebook->getLogoutUrl(); } else { $loginUrl = $facebook->getLoginUrl(); }

  • Ruby array, javascript and json issue

    - by JohnMerlino
    Hey all, I am unable to get a highcharts plugin to render a chart in a rails application: http://github.com/loudpixel/highcharts-rails I believe it has something to do with the sql queries to the database placed in a ruby array, which the javascript is unable to intepret. This is what I have: def panels pass = Student.find_by_sql('SELECT COUNT(*) FROM students WHERE student_state = 1') fail = Student.find_by_sql('SELECT COUNT(*) FROM students WHERE student_state = 2') student_data = [ {:name => 'Pass', :y => pass}, {:name => 'Fail', :y => fail} ] pie_label_formatter = ' function() { if (this.y > 15) return this.point.name; }' pie_tooltip_formatter = ' function() { return "<strong>" + this.point.name + "</strong>: " + this.y + " %"; }' @pie_chart = Highchart.pie({ :chart => { :renderTo => "pie-chart-container", :margin => [50, 30, 0, 30] }, :plotOptions => { :pie => { :dataLabels => { :formatter => pie_label_formatter, :style => { :textShadow => '#000000 1px 1px 2px' } } } }, :series => [ { :type => 'pie', :data => student_data } ], :subtitle => { :text => 'April 2010' }, :title => { :text => 'Student Status Chart' }, :tooltip => { :formatter => pie_tooltip_formatter }, }) Note if I put this: :data = student_data.to_json It actually returns a json string of my query as text in the browser. Also, if I hard code values (e.g. :y = 1), it will render the chart properly. However, any database query will not render the chart properly. So I'm not sure exactly what the issue is. Any suggestions? Thanks.

  • Is it necessary to "escape" character "<" and ">" for javascript string?

    - by Morgan Cheng
    Sometimes, server side will generate strings to be embedded in inline JavaScript code. For example, if "UserName" should be generated by ASP.NET. Then it looks like. <script> var username = "<%UserName%>"; </script> This is not safe, because a user can have his/her name to be </script><script>alert('bug')</script></script> It is XSS vulnerability. So, basically, the code should be: <script> var username = "<% JavascriptEncode(UserName)%>"; </script> What JavascriptEncode does is to add charater "\" before "/" and "'" and """. So, the output html is like. var username = "<\/scriptalert(\'bug\')<\/script<\/script"; Browser will not interpret "<\/script" as end of script block. So, XSS in avoided. However, there are still "<" and "" there. It is suggested to escape these two characters as well. First of all, I don't believe it is a good idea to change "<" to "&lt;" and "" to "&gt;" here. And, I'm not sure changing "<" to "\<" and "" to "\" is recognizable to all browsers. It seems it is not necessary to do further encoding for "<" and "". Is there any suggestion on this? Thanks.

  • Refreshing Facebook session from an iframe application

    - by zombat
    I've got a Facebook iframe application that is completely external. By this I mean that once a user accesses the canvas URL to load the application, all the links in the iframe app go to my servers, and the canvas page never gets refreshed unless the user navigates to somewhere else on Facebook and comes back (or does a browser refresh). On the initial load of the app where Facebook creates the iframe, I get passed all the usual parameters like fb_sig_user which allows me to create an internal app session based on the facebook user. This app session (which is not the Facebook session, it's my own app session) is all I need to allow the user to work with the app. The problem comes an hour later. If the user leaves the computer, or uses the app for more than an hour, the Facebook session expires. There are some app pages which require fetching friend information, and once the FB session has expired, these pages break, throwing out errors such as "Error: Session key invalid or no longer valid". My question is whether there is a way to refresh the user's Facebook session from within an iframe application to keep it from expiring an hour later. Do any of the API calls do this? Is there a Facebook Connect trick to ping something? Is there any definitive method to keep it alive? I haven't been able to find any examples that specifically address this.

  • What does ~ in the beginning of an URL in asp.net exactly do ?

    - by MarceloRamires
    I am editing a certain website which before used the port 80 (default) that was not required at the url (because it's default..) But the port had (for technical reasons) to be changed, and now it has to be informed. I can access the main page through ip:port\page like this: 1.2.3.4:81\page.aspx Every link in the website is composed like this: <asp:HyperLink runat="server" Text="random" NavigateUrl="~/fdr/whatever.aspx" /> And whenever I click on a link, the page doesn't load, but the URL is composed on the URL bar of the browser, then I simply add ":80" after the IP in the URL and it works. Due to the existance of querystrings (in other words, for already having access to the URL) I before thought that '~' in the beginning of a URL in a link was saying "keep in the same website, just change to this webpage in this folder", but if the port vanishes, I assume now that the address is requested (probably to IIS) the location of the current website. I want to know then (instead of having to add the port to each link in my website) how do I set up whoever is requested by the ~ in the link to add the port somehow. How do I do that?

  • ASP.NET Webforms site using HTTPCookie with 100 year timeout times out after 20 minutes

    - by Rob
    I have a site that is using Forms Auth. The client does not want the site session to expire at all for users. In the login page codebehind, the following code is used: // user passed validation FormsAuthentication.Initialize(); // grab the user's roles out of the database String strRole = AssignRoles(UserName.Text); // creates forms auth ticket with expiration date of 100 years from now and make it persistent FormsAuthenticationTicket fat = new FormsAuthenticationTicket(1, UserName.Text, DateTime.Now, DateTime.Now.AddYears(100), true, strRole, FormsAuthentication.FormsCookiePath); // create a cookie and throw the ticket in there, set expiration date to 100 years from now HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName, FormsAuthentication.Encrypt(fat)) { Expires = DateTime.Now.AddYears(100) }; // add the cookie to the response queue Response.Cookies.Add(cookie); Response.Redirect(FormsAuthentication.GetRedirectUrl(UserName.Text, false)); The web.config file auth section looks like this: <authentication mode="Forms"> <forms name="APLOnlineCompliance" loginUrl="~/Login.aspx" defaultUrl="~/Course/CourseViewer.aspx" /> </authentication> When I log into the site I do see the cookie correctly being sent to the browser and passed back up: However, when I walk away for 20 minutes or so, come back and try to do anything on the site, the login window reappears. This solution was working for a while on our servers - now it's back. The problem doesn't occur on my local dev box running Cassini in VS2008. Any ideas on how to fix this?

  • XMLHttpRequest open() returning access denied

    - by rjovic
    Hi! I have problem with xhr open() method. My code follows : var xmlhttp=false; if(!xmlhttp) try { xmlhttp=new XMLHttpRequest(); } catch(e) { xmlhttp=false; } function returnPage(url) { if(!xmlhttp) return alert("Your browser doesn't seem to support XMLHttpRequests."); xmlhttp.open("GET",url,true); xmlhttp.onreadystatechange=function() { if(xmlhttp.readyState!=4) return; if(!xmlhttp.status||xmlhttp.status==200) alert(xmlhttp.responseText); else alert("Request failed!"); }; //onreadystatechange xmlhttp.send(null); } Call : <a href='#' onclick="returnPage('http://www.something.com'); return false;">Link 1</a></p> I'm using IE8 (because I'm building web slice) and I received error "Access denied". I found on the Internet that problem is that XHR isn't working across different domains, but I used code from Firefox Add-on which is working OK. And that add-on and "my" code (which are the same) are calling the same page. How that add-on have access and my code not?

  • How to store a file on a server(web container) through a Java EE web application?

    - by Yatendra Goel
    I have developed a Java EE web application. This application allows a user to upload a file with the help of a browser. Once the user has uploaded his file, this application first stores the uploaded file on the server (on which it is running) and then processes it. At present, I am storing the file on the server as follows: try { FormFile formFile = programForm.getTheFile(); // formFile represents the uploaded file String path = getServlet().getServletContext().getRealPath("") + "/" + formFile.getFileName(); System.out.println(path); file = new File(path); outputStream = new FileOutputStream(file); outputStream.write(formFile.getFileData()); } where, the formFile represents the uploaded file. Now, the problem is that it is running fine on some servers but on some servers the getServlet().getServletContext().getRealPath("") is returning null so the final path that I am getting is null/filename and the file doesn't store on the server. When I checked the API for ServletContext.getRealPath() method, I found the following: public java.lang.String getRealPath(java.lang.String path) Returns a String containing the real path for a given virtual path. For example, the path "/index.html" returns the absolute file path on the server's filesystem would be served by a request for "http://host/contextPath/index.html", where contextPath is the context path of this ServletContext. The real path returned will be in a form appropriate to the computer and operating system on which the servlet container is running, including the proper path separators. This method returns null if the servlet container cannot translate the virtual path to a real path for any reason (such as when the content is being made available from a .war archive). So, Is there any other way by which I can store files on those servers also which is returning null for getServlet().getServletContext().getRealPath("")

  • Classic ASP on IIS 7

    - by jagr
    Hi, I am having problems with my app running on IIS 7. The application is a mixture of classic ASP and ASP.NET MVC (don't ask how and why). Anyway, the application is up and running except for some problems that I am experiencing. For example, I have a button on my page and when I click it, javascript is opening a popup which needs to contain .asp page. But that doesn't happen. I get the blank popup with my cursor on busy as it still loads. This is happening almost always to me in IE. In Firefox it is much better but sometimes the app jams there too. If I close the opened, blank popup, and I want to move around the application, my buttons in menu (which are also .asp) doesn't load properly. For example, I have different buttons for different sections and when I move around they should change. When I restart the browser, only then everything works normal for some time, but the problem occurs again after a while. I am very sure that it is not the problem in application itself, because it works properly on the machines of my colleagues without those problems. They have the same OS (Vista Professional) and we compared the settings in IIS and they match. So I am very confused, and I really don't know how to solve the problem. I found a bunch of articles and blog posts about classic ASP and IIS7 but most of them are about enabling asp, which I already did. So I am suspecting that something wrong with IIS, but I don't know what, tried to reinstall it, hoping for some improvement, but I had no luck. If you need more details please ask. Does anyone have any idea what should I try or do?

  • Change the content type of a pop up window.

    - by Oscar Reyes
    This question brought a new one: I have a html page and I need it to change the content type when the user press "save" button so the browser prompt to save the file to disk I've been doing this in the server side to offer "excel" versions of the page ( which is basically a html table ) <c:if test="${page.asExcelAction}"> <% response.setContentType("application/vnd.ms-excel"); %> What I'm trying to do now is to do the same, but in the client side with javacript but I can't manage to do it so. This is what I've got so far: <html> <head> <script> function saveAs(){ var sMarkup = document.getElementById('content').innerHTML; //var oNewDoc = document.open('application/vnd.ms-excel'); var oNewDoc = document.open('text/html'); oNewDoc.write( sMarkup ); oNewDoc.close(); } </script> </head> <body> <div id='content'> <table> <tr> <td>Stack</td> <td>Overflow</td> </tr> </table> </div> <input type="button" value="Save as" onClick="saveAs()"/> </body> </html>

  • JavaScript Exception/Error Handling Not Working

    - by Seán Hayes
    This might be a little hard to follow. I've got a function inside an object: f_openFRHandler: function(input) { console.debug('f_openFRHandler'); try{ //throw 'foo'; DragDrop.FileChanged(input); //foxyface.window.close(); } catch(e){ console.error(e); jQuery('#foxyface_open_errors').append('<div>Max local storage limit reached, unable to store new images in your browser. Please remove some images and try again.</div>'); } }, inside the try block it calls: this.FileChanged = function(input) { // FileUploadManager.addFileInput(input); console.debug(input); var files = input.files; for (var i = 0; i < files.length; i++) { var file = files[i]; if (!file.type.match(/image.*/)) continue; var reader = new FileReader(); reader.onload = (function(f, isLast) { return function(e) { if (files.length == 1) { LocalStorageManager.addImage(f.name, e.target.result, false, true); LocalStorageManager.loadCurrentImage(); //foxyface.window.close(); } else { FileUploadManager.addFileData(f, e.target.result); // add multiple files to list if (isLast) setTimeout(function() { LocalStorageManager.loadCurrentImage() },100); } }; })(file, i == files.length - 1); reader.readAsDataURL(file); } return true; LocalStorageManager.addImage calls: this.setItem = function(data){ localStorage.setItem('ImageStore', $.json_encode(data)); } localStorage.setItem throws an error if too much local storage has been used. I want to catch that error in f_openFRHandler (first code sample), but it's being sent to the error console instead of the catch block. I tried the following code in my Firebug console to make sure I'm not crazy and it works as expected despite many levels of function nesting: try{ (function(){ (function(){ throw 'foo' })() })() } catch(e){ console.debug(e) } Any ideas?

  • Image Grabbing with False Referer

    - by Mr Carl
    Hey guys, I'm struggling with grabbing an image at the moment... sounds silly, but check out this link :P http://manga.justcarl.co.uk/A/Oishii_Kankei/31/1 If you get the image URL, the image loads. Go back, it looks like it's working fine, but that's just the browser loading up the cached image. The application was working fine before, I'm thinking they implemented some kind of Referer check on their images. So I found some code and came up with the following... $ref = 'http://www.thesite.com/'; $file = 'theimage.jpg'; $hdrs = array( 'http' = array( 'method' = "GET", 'header'= "accept-language: en\r\n" . "Accept:application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*\/*;q=0.5\r\n" . "Referer: $ref\r\n" . // Setting the http-referer "Content-Type: image/jpeg\r\n" ) ); // get the requested page from the server // with our header as a request-header $context = stream_context_create($hdrs); $fp = fopen($imgChapterPath.$file, 'rb', false, $context); fpassthru($fp); fclose($fp); Essentially it's making up a false referrer. All I'm getting back though is a bunch of gibberish (thanks to fpassthru) so I think it's getting the image, but I'm afraid to say I have no idea how to output/display the collected image. Cheers, Carl

  • How does jquery display an image received from an ajax request?

    - by Gnee
    I have this working great, but I'd like a deeper understanding of what is actually going on behind the scenes. I am using Jquery's Ajax method to pull 5 blog posts (returning only the title and first photo). A PHP script grabs the blog posts' title and first photo and sticks it in an array and sends it back to my browser as JSON. Upon receiving the JSON object, Jquery grabs the first member of the JSON object and displays it's title and photo. In a gallery I made, using buttons – the user can iterate the 1-5 posts. So the actual AJAX call happens right away, and only once. I am basically using this kind of setup: $('my_div').html(json_obj[i]) and each click does a i++. So jquery is plucking these blog posts from my computers memory, my web browsers cache, or some kind of cache in the Javascript engine? One of the things it's returning is a pretty gnarly animated gif. I just wonder if it constantly running in the background (but not visible), stealing processing cycles...etc. Or Javascript just inserting (say a flash movie) into the DOM, but before hand does nothing but take up a little memory (no processing). Anyway, I'm just curious. If someone is a guru on this, I'd love to hear your take. Thanks!!

  • Grails - Language prefix in url mappings

    - by Art79
    Hi there im having problem with language mappings. The way i want it to work is that language is encoded in the url like /appname/de/mycontroller/whatever If you go to /appname/mycontroller/action it should check your session and if there is no session pick language based on browser preference and redirect to the language prefixed site. If you have session then it will display english. English does not have en prefix (to make it harder). So i created mappings like this: class UrlMappings { static mappings = { "/$lang/$controller/$action?/$id?"{ constraints { lang(matches:/pl|en/) } } "/$lang/store/$category" { controller = "storeItem" action = "index" constraints { lang(matches:/pl|en/) } } "/$lang/store" { controller = "storeItem" action = "index" constraints { lang(matches:/pl|en/) } } "/$controller/$action?/$id?"{ lang="en" constraints { } } "/store/$category" { lang="en" controller = "storeItem" action = "index" } "/store" { lang="en" controller = "storeItem" action = "index" } "/"(view:"/index") "500"(view:'/error') } } Its not fully working and langs are hardcoded just for now. I think i did something wrong. Some of the reverse mappings work but some dont add language. If i use link tag and pass params:[lang:'pl'] then it works but if i add params:[lang:'pl', page:2] then it does not. In the second case both lang and page number become parameters in the query string. What is worse they dont affect the locale so page shows in english. Can anyone please point me to the documentation what are the rules of reverse mappings or even better how to implement such language prefix in a good way ? THANKS

  • With Google Website Optimizer's multivariate testing, can I vary multiple css classes on a single di

    - by brahn
    I would like to use Google Website Optimizer (GWO)'s multivariate tests to test some different versions of a web page. I can change from version to version just by varying some class tags on a div, i.e. the different versions are of this form: <div id="testing" class="foo1 bar1">content</div> <div id="testing" class="foo1 bar2">content</div> <div id="testing" class="foo2 bar1">content</div> <div id="testing" class="foo2 bar2">content</div> In the ideal, I would be able to use GWO section code in place of each class, and google would just swap in the appropriate tags (foo1 or foo2, bar1 or bar2). However, naively doing this results in horribly malformed code because I would be trying to put <script> tags inside the div's class attribute: <div id="testing" class=" <script>utmx_section("foo-class")</script>foo1</noscript> <script>utmx_section("bar-class")</script>bar1</noscript> "> content </div> And indeed, the browser chokes all over it. My current best approach is just to use a different div for each variable in the test, as follows: <script>utmx_section("foo-class-div")</script> <div class="foo1"> </noscript> <script>utmx_section("bar-class-div")</script> <div class="bar1"> </noscript> content </div> </div> So testing multiple variables requires layer of div-nesting per variable, and it all seems rather awkward. Is there a better approach that I could use in which I just vary the classes on a single div?

  • jQuery check offset

    - by Glister
    HTML: <ul class="clients"> <li> <div class="over left">Description</div> <div class="inner">Image</div> </li> </ul> CSS: .clients { margin-right: -20px; } .clients li { float: left; width: 128px; height: 120px; margin: 0 20px 20px 0; border: 1px solid #c2c2c2; } .clients .over { display: none; position: absolute; width: 250px; font-size: 11px; line-height: 16px; background: #ecf5fb; margin: 3px 0 0 3px; padding: 18px; z-index: 25; } .clients .right { margin: 3px 0 0 -161px; } .clients .inner { width: 128px; height: 120px; overflow: hidden; } So, we have a list of floated squares and a popup blocks in each, which have absolute position. JS: jQuery(function($) { $('input[title!=""]').hint(); $(".clients li").bind('mouseover mouseout',function(){$(this).find("div.over").toggle()}); }); If over - show, else - hide. Quite ok, but it must be more advanced, we should catch an offset and give a class to .over block: if offset from right (corner of browser window) less than 150px, then add class "right" for a .over block. if offset from right more than 150px - add class "left" for a .over block. How can we do it?

  • Session cookie not being created in Rails, very rarely and frustratingly.

    - by James
    Hi everyone, This is an issue sporadically for very few users, however we haven't been able to replicate it. However I have now got a Chrome instance (Mac) which is reproducing the error (for some unknown reason), and I hope to not restart it until I have this nailed! Rails application, using memcached for session store. While the bug manifests in the _app_session_id cookie not being created, our javascript-generated cookie test and app-generated language cookies are being created successfully. This means that 422 / InvalidAuthToken errors are thrown for every form that is submitted by those afflicted - people can't log into the app. The error occurs across all browsers - had reports for IE7 and Firefox (which most users use). Switching to another browser often fixes the issue (though not always), and standard cache-cookie-clear tactics do not. So now that I have got Chrome open which is having the same issue - in development, staging and live environments (meaning http and https). All other browsers are fine. I've restarted the servers and restarted memcached. I don't really want to restart Chrome - in the risk that the issue does go away with that (having said that, it hasn't worked for users). I've been tcpdumping the requests - and although I'll keep digging, I'd love it if anyone had any suggestions, places to start looking, anything. This is really painful ;) Thanks!
