• Catch all javascript errors and send them to server

  - by ssaboum

  Hi everyone, i wandered if anyone had experience in handling javascript errors globally and send them from the client browser to a server. I think my point is quite clear, i want to know every exceptions, errors, compilation errors, ... that happens on the client side and send them to the server to report them. I'm mainly using mootools and head.js (for the js side) and django for the server side (not that it matters...). Thank you for your help. Regards.

• Sequencing ajax requests

  - by Scott Evernden

  I find I sometimes need to iterate some collection and make an ajax call for each element. I want each call to return before moving to the next element so that I don't blast the server with requests - which often leads to other issues. And I don't want to set async to false and freeze the browser. Usually this involves setting up some kind of iterator context that i step thru upon each success callback. I think there must be a cleaner simpler way? Does anyone have a clever design pattern for how to neatly work thru a collection making ajax calls for each item?

• Prevent blank links (having javascript:;) from openening in new tab/window on middle click...?

  - by jayarjo

  There is a common practice of using <a></a> tags to markup beautiful buttons, with onlick and onhover style change, etc. Which looks and behaves great, on most part. Although there turned out to be a HUGE problem, which was not very obvious on start. The problem is that these beautiful "buttons" open new windows on middle click, either blank or with the same content as current one (depends on whether one uses # or javascript:; to disable href part). Now I've got JavaScript RIA with buttons all over it, opening new windows on middle click... Lame... At first I even couldn't understand why I get sometimes those blank pages in the browser. Since it's pretty established practice to use links in such manner, maybe there is any established way to deal with described problem?

• "Send it to a friend" button on a webpage

  - by kender

  Hey, How often do we see stuff like "Send this page to a friend" on a webpages? Well, I see them quite often. My question is, how do you guys see it's effectiveness? If I hit a webpage that's interesting, and I think my friend would enjoy it, I can just copy the URL from my browser bar, paste it into the email and press "Send" button. In my opinion, it's usually faster and less mistake-aware then the button/link like this on the webpage. In addition, I'm not really sure what this website does with the emails I enter there - don't they store it and then sell for $1/100 addresses to spammers? My question is - when you design a website, do you put such links on the pages (it's often seen on sites with some news/articles)? Does it even make sense?

• What format is your documentation in?

  - by Ek0nomik

  I am going to be writing documentation for two web services that I developed, and I started wondering what people on here do for documentation. Do you create it in an HTML file so it can be viewed in the browser? Word document? Wiki? What do you guys/gals use? I was originally leaning towards creating an HTML page since it seems a little more open and friendly than a word document. Plus I can use the prettify javascript to make code samples look nice. Our company has a Sharepoint though, so an HTML file may not be the best choice given that most documentation is put up in spreadsheets and word documents.

• ASP.NET : What exactly is affected when Javascript is off?

  - by rlb.usa

  I've heard different stories about ASP.NET and JavaScript: that it works fine with Javascript turned off, that only some parts don't work, and that nothing works at all. How exactly are ASP.NET applications affected if JavaScript is turned off in a client's browser? What parts don't work (if any)? For example, will RequiredFieldValidators still work? What about UploadControls? AJAX UpdatePanels and AsyncPostBack's? FileUploads? Do page codebehinds still run? Forgive my ignorance, I can't seem to find much about the issue that is in-depth.

• How to persist a cookie?

  - by user246114

  Hi, I am creating a cookie in a jsp script, which is located at: www.myproject.com/login/index.jsp if I restart the browser and navigate there, all works well, I can see the cookie persist. If I navigate to: www.myproject.com I am not seeing the cookie. Do I need to set something in the cookie path or domain to make the cookie visible to the entire [myproject.com] domain (I just want to access the cookie from whatever sub path the user may be on). I am creating the cookie like: Cookie c = new Cookie("thisisatest", "foo"); c.setMaxAge(60 * 24 * 3600); response.addCookie(c); Thanks

• What is the best way to make a game timer in Actionscript 3?

  - by Nuthman

  I have built an online game system that depends on a timer that records how long it took a player to complete a challenge. It needs to be accurate to the millisecond. Their time is stored in a SQL database. The problem is that when I use the Timer class, some players are ending up getting scores in the database of less than a second. (which is impossible, as most challenges would take at least 11 seconds to complete even in a perfect situation.) What I have found is that if a player has too many browser windows open, and/or a slow computer, the flash game slows down actually affecting the timer speed itself. The timer is 'spinning' on screen so you can physically see the numbers slowing down. It is frustrating that I cannot just open a second thread or do something to allow flash to keep accurate time regardless of whatever else is going on in the program. Any ideas?

• how to verify that an old session is really destroyed?

  - by jodeci

  Um, this might sound a bit weird. We were having some problems with a specific browser under a very specific condition, and finally narrowed down the problem to the fact that we were not properly destroying the old sessions after doing session_regenerate_id(). I believe I have solved this problem by doing session_regenerate_id(true) now, but how does one verify that the previous sessions really do not exist any more? Someone suggested cURL but I cannot find my way around their docs. Sadly(?) the boss does not take 'it just works' for an answer so I'd really appreciate any advice!

• how to handle large dataset like sproutcore

  - by Nik

  Hello all, I really don't have any substantial code to show here, actually, that's kinda why I am writing: I looked at the SproutCore demo, especially the Collection demo, on http://demo.sproutcore.com/sample_controls/, and am amazed by its loading 200,000 records to the page so easily. I tried using Rails to provide 200,000 records and in a completely blank HTML page with <% @projects.each do |p| % <%= p.title % <% end % that freezes the browser for seconds on my m1530 laptop with 4gb ram and t7700 256gb ssd. Yet the sproutcore demo does not freeze and takes less than 3 seconds to load. What do you think the one technique they are using to enable this is? Thanks!

• What is the difference between "render a view" and send the response using the Response's method "sendResponse()"?

  - by Green

  I've asked a question about what is "rendering a view". Got some answers: Rendering a view means showing up a View eg html part to user or browser. and So by rendering a view, the MVC framework has handled the data in the controller and done the backend work in the model, and then sends that data to the View to be output to the user. and render just means to emit. To print. To echo. To write to some source (probably stdout). but don't understand then the difference between rendering a view and using the Response class to send the output to the user using its sendResponse() method. If render a view means to echo the output to the user then why sendResponse() exists and vise versa? sendResponse() exactly sends headers and after headers outputs the body. They solve the same tasks but differently? What is the difference?

• Character encoding problem in my website.

  - by vikyboss

  I own a website that was recently moved to a different server, now I can see some weird characters. Initially the website was coded with UTF-8 encoding. The weird characters disappears if I change the View Character encoding to Western(8859-1) in my browser. Therefore, I changed the source of the website to use this Western one, but still I can see the weird characters and they doesn't seem to disappear. Can anyone help me with this. Thanks in advance.

• Problem with displaying my Image..

  - by Josh

  Here is my full problem so if anyone has any ideas or can offer some help, please let me know. I have a Website that will generate a Report and this Report takes some time to create. There is a MyReport.ASPX file that has a form1, Image1, and a ReportViewer control. There is also a MyReport.cs file that has C# code to generated a HTMLText string that the ReportViewer control will display. When I pull the Website up in the browser, the MyReport.cs file creates the Report before MyReport.ASPX ever gets called so my Image1 (which I need to display while the Report is being created) never gets displayed until AFTER the Report is created and displayed. What do you suggest I do here? If I did not supply enough information, please let me know what else you need to know and I will gladly post it. Thanks,

• Firefox 17.0.1 ignoring font-weight

  - by jphogan

  http://iamsinc.com/blog/new-producer-bonus/ For some reason Firefox 17.0.1 on my Windows 7 machine is ignoring the font-weight of the td elements. It should be normal. This works fine in Chrome, IE 7 8, & 9, but not in FF. I have also tested it on an XP machine running 17.0.1 and it works fine. The font-weight should be normal, not bold. In the second box down ($300k level), the font-weight is showing up as bold on Win 7 FF 17.0.1 which pushes the pictures outside of the box. I have even tried reducing the font-weight waaay down and it has not effect on the problematic FF browser Does anybody have a solution or even a work-around? I hate to make the pictures all smaller just to work around this. Thanks!

• Javascript to detect where newly opened window came from

  - by teggy

  Let's say I have a page, http://mydomain.com/mypage.html, with a "Back to page" link. This link should take the user back to the page where they came from only if the previous page URL matches one of the following: http://mydomain.com/one.html, http://mydomain.com/two.html, and http://mydomain.com/three.html. Otherwise, it would take the user back to the homepage, http://mydomain.com. I would like the "Back to page" link to also take the user back to the homepage when http://mydomain.com/mypage.html is pasted onto the browser. How can i accomplish this with Javascript. Thanks!

• How to apply dynamically scale down and up into a thumbnail images size?

  - by Qpixo

  I'm working on one current project, I don't have any issues to load a SWF into a main SWF but I can't figure out how to apply dynamically the scale down and up into a thumbnail images size while using the Resize event handler. I load SWF into a Loader object then add it into a container = currentMC. I want to size it and keep all the pieces inside this container. Therefore no matter browser size, I just want to be able to apply scale on it to fit it. Does anyone know how to do that? Any code examples would help me a lot. I'm using Flash.

• How can I get rid of horizontal padding or indent in html5 search inputs in webkit?

  - by Scott Vandehey

  In webkit only, the text in a search input is indented from the left side. Here's a demo. Even after stripping all padding, text-indent, and setting -webkit-appearance to textfield or none, the text is still indented. It looks to be around 10px or so, but the inspector doesn't show any CSS rules (even browser defaults) that seem to apply this style. Any ideas? <input type="search" value="Search"> -webkit-appearance: textfield; border: 1px solid #ccc; padding: 0; margin: 0; text-indent: 0;

• Can a plain servlet be configured to as a seam component?

  I created a plain servlet within a seam-gen (2.1.2) application, now I would like to use injection. Thus I annotated it with @Name and it's recognized as component: INFO [Component] Component: ConfigReport, scope: EVENT, type: JAVA_BEAN, class: com.mycompany.servlet.ConfigReport Unfortunatly the injection of the logger doesn't work NullPointerException in init() import org.jboss.seam.annotations.Logger; import org.jboss.seam.annotations.Name; import org.jboss.seam.log.Log; @Name("ConfigReport") public class ConfigReport extends HttpServlet { @Logger private Log log; public void init(ServletConfig config) throws ServletException { log.info( "BOOM" ); } } Is my approach abusive? What would be the alternatives (the client sending requests to the servlet is curl, not a browser)?

• Failed to load viewstate...

  Yes, it's the infamous viewstate again! Now I am aware that problems can ocurr if you load controls in the wrong order or if the viewstate IDs are incorrect after postbacks etc etc. But my issue is that I am not really creating any controls dynamically - I only have one user control on the page. More importantly, the issue seems to be occuring with just one user. What could be the problem? Corrupt browser cache? Any help appreciated. thanks, KS

• providing a java servlet with information

  - by tom

  Hi, i am new to servlets. I made a simple hello world programme that prints those famous 2 words to the screen when i access the page via a browser using http://localhost:8080/mypath/path... My question is now, how do i provide a servlet with information? Specifically considering the fact that my c# programme calculates a lookup value for a global system, then the "java" servlet processes that and returns a set of results. I have done the reverse thanks to help on here, regarding calling a returned string from the java servlet in c#. However i am not sure how i go about providing the servlet information. Do i pass it via the url? Thank you

• Is there a work around for setAppCacheEnabled on WebView for an Android 2.1 application causing the

  - by Kevin

  We have an HTML 5.0 web application that we ported to Android. It's our intention to run this in a Native Wrapper. Our application uses the ApplicationCache to run offline. This works find when running under the browser. While being hosted in a WebView within a native application, after the last file is downloaded and stored in the ApplicationCache from the manifest the application is terminated and does a core dump. This appears to be a documented bug. http://code.google.com/p/android/issues/detail?id=7939 Has anyone doing anything similar found a work around for this issue?

• Browsing to Subversion repository location indicated in Apache conf file

  - by sonrael

  I have Subversion 1.6.6 and Apache 2.2.14 installed and working. I have made the following changes to the Apache httpd.conf file: #Uncommented by me for Subversion installation LoadModule dav_module modules/mod_dav.so LoadModule dav_fs_module modules/mod_dav_fs.so #Added by me for subversion installation LoadModule dav_svn_module modules/mod_dav_svn.so LoadModule authz_svn_module modules/mod_authz_svn.so < Location /svn DAV svn SVNPath C:\Users\RED\Repositories < /Location ...When I navigate to localhost Apache is working properly, but if I try to go to localhost/svn the browser just hangs waiting for a response from the server. What is supposed to happen here? Does it have to do with the fact that I'm behind a wireless router on a dynamic IP address (although I can access localhost no problem so...)? As you can see I'm on windows (Vista)
