• CKEDITOR, is return some strange characters

  - by nobosh

  With CKEDITOR, when I use JS to get the contents of the Text Editor, I'm getting back: <p>\u000a\u0009&nbsp;ad adad ad asd</p>\u000a When I should have gotten: <p>ad adad ad asd</p> Any idea what's going on here? The only difference that could be the cause is that I'm dynamically created textareas on load, and using a class to find the editor: $('.guideItem-textarea').each(function(index, value){ // ID of the textarea var targeteditor = $(this).attr('id'); var targeteditorID = $(this).attr('id').replace('noteguide',''); // Contents in the editor textareacontents = CKEDITOR.instances[targeteditor].getData(); }); Any ideas?

• Creating a loading screen in HTML5

  - by espais

  I am having some issues finding a decent tutorial for generating a loading style screen with regards to HTML5. To be quite honest I'm not sure exactly where to begin... My project is essentially a simple HTML5 game, where I'll be loading in various sprite sheets and tilesets. They'll be reasonably small, but I'd like to show a little loading spinner instead of a blank screen while all the resources are loaded. Much appreciated if somebody could point me in the right direction, be it decent links or code samples to get me going...my Google-fu is lacking today! For clarification, I need to figure out how to load the resources themselves, as opposed to finding a spinner. For instance, how to calculate that X% has loaded.

• Babel Django Off By 1 Cent

  - by Dave

  I ran into a problem today while using BabelDjango and thought I would ask if anyone has ran into anything similar. I was using the tags in my templates, {% load babel %} and then {{amount_owed|currencyfmt:"USD"}} which returned the amount_owed minus one-cent. I thought maybe the returned value was 9.949999 which should still be $9.95 but when I returned the raw value it returned "9.95". However when I formatted it using the babel tags the rsult was off by one-cent. My 9.95 returned "$9.94" Anyone have any advice where to look to troubleshoot this problem? Thanks in advance for your help.

• Rails 3 jQuery UI Slider

  - by Tyler DeWitt

  I'm trying to use the jQuery UI Slider with my rails 3 app. I've downloaded a theme and put the css file in app/assets/stylesheet and I put all the images in app/assets/images.

• JQuery Selector - Select this, not that?

  - by JasonS

  Hi, I have created a script which is surprisingly working. (I do not do much JavaScript) What I have is a load of images listed within a div. These images are hidden. JQuery gets the properties of the images and puts them into an array. When the body is clicked, the background image of the page changes. This works nicely. However, I now have a problem. There are several elements which I shouldn't change the background when they are clicked. Namely, navigation, footer and caption. How do I create a selector which makes the body clickable, yet ignores clicks on the above 3 div's?

• Animate rotating SVG element on webpage

  - by Zarkonnen

  So I have an SVG file created in Inkscape embedded in a webpage, and I'd like it to rotate slowly. I've tried using Javascript and inserting animation commands directly into the SVG, but nothing works. I don't want to load in an entire JS library for this one task. This is what I have so far: <html> <body bgcolor="#333333"> <embed src="gear.svg" id="gear" width="1000" height="1000" style="position: absolute; top: -500px; left: -500px;" /> <script type="text/javascript"> var gear = document.getElementById("gear"); window.setInterval(function() { // Somehow animate the gear. }, 10); </script> </body> </html>

• How do you unpack gems using jruby on rails 2.3?

  - by James Moore

  I'm trying to unpack all the system gems to end up with a standalone Rails directory including all the rails gems and all the system gems. I'm starting with a bare rails setup; just did a jruby -S rails and a 'generate jdbc'. I then add a config.gem 'jdbc-mysql' to environment.rb and do the jruby -S rake gems:unpack:dependencies. After unpacking, if I do a rake I get: no such file to load -- jdbc-mysql Is there something else you need to do to get the jdbc gem unpacked? I'm using jruby 1.4.0 (and moving to 1.5 is on my todo list) and rails 2.3.8.

• Singleton constructor question

  - by gillyb

  Hi, I created a Singleton class in c#, with a public property that I want to initialize when the Singleton is first called. This is the code I wrote : public class BL { private ISessionFactory _sessionFactory; public ISessionFactory SessionFactory { get { return _sessionFactory; } set { _sessionFactory = value; } } private BL() { SessionFactory = Dal.SessionFactory.CreateSessionFactory(); } private object thisLock = new object(); private BL _instance = null; public BL Instance { get { lock (thisLock) { if (_instance == null) { _instance = new BL(); } return _instance; } } } } As far as I know, when I address the Instance BL object in the BL class for the first time, it should load the constructor and that should initialize the SessionFactory object. But when I try : BL.Instance.SessionFactory.OpenSession(); I get a Null Reference Exception, and I see that SessionFactory is null... why?

• Using type hints in Clojure for Java return values

  - by mikera

  I'm working on some Java / Clojure interoperability and came across a reflection warning for the following code: (defn load-image [resource-name] (javax.imageio.ImageIO/read (.getResource (class javax.imageio.ImageIO) resource-name))) => Reflection warning, clojure/repl.clj:37 - reference to field read can't be resolved. I'm surprised at this because getResource always returns a URL and I would therefore expect the compiler to use the appropriate static method in javax.imageio.ImageIO/read. The code works fine BTW so it is clearly finding the right method at run time. So two questions: Why is this returning a reflection warning? What type hint do I need to fix this?

• Add CSS Class to link based on Character Count with jquery

  - by Wes

  I have links that load dynamically onto a background to make them look like buttons. Some of the links take up two lines and some of the links take up 1 line. Eithe way they need to be vertically centered. My plan to to append a class based on the number of characters and then adjust the padding from there. So if the link's text is 25 characters (including spaces) or less - append class 'small' if the link's text is greater than 25 characters - append class 'large' How would I go about doing this with jQuery?

• Flex RemoteObject Intermittently Failing to Invoke CFC

  - by Justin

  I have a Flex app that uses Flash Remoting and the RemoteObject to pull data from a ColdFusion CFC. About 75% of the time it works, but the other times I get a message using Charles (a debugging tool) that says faultString = "Unable to Invoke CFC". FaultCode = "Server.Processing". Here's my RemoteObject: The server set up on our web farm is to use load balancing. I'm not sure if this is causing the problem or not. Probably not, but it's a thought. Any help is appreciated!!

• IntelliJ doesn't seem to pickup certain sbt libraries, no code completion

  - by Blankman

  I am using sbt console in my terminal to compile my scala/play project. I am using intellij to edit my source code, basically using it just for getting some code completion and navigation etc. For some reason certain libraries don't seem to load correctly. For example, I added elastic search to my Dependancies.scala file, reloaded sbt and everything compiles fine but for some reason IntelliJ doesn't pickup the jars correctly i.e. they are in red and there is no syntax completion. How can I fix this? I tried shutting intellij down and restarting it but the problem remains. I am using Intelli 13.1.3 (ultimate)

• Generics in custom configuration sections

  - by Jonn

  I tried making a custom configuration class that went on like this: WatcherServiceInfoSection<TWatcherServiceDetailElement> where TWatcherServiceDetailElement is a ConfigurationElement inside it. Now when I call the type in the ConfigSections area of AppConfig I get the error: An error occurred creating the configuration section handler for WatcherServiceInfo: Could not load type 'Library.Common.Utilities.ConfigurationHandler.WatcherServiceInfoSection<ASNDPService.Configuration.WatcherServiceDetailElement>' from assembly Is what I'm doing possible? Can I have generic types in the type attribute for a custom section element? EDIT Additionally, how about ConfigurationElementCollection objects? Like in the above example, how could I do a [ConfigurationProperty("WatcherServiceDetails", IsRequired = true, IsDefaultCollection = true)] [ConfigurationCollection(typeof(TWatcherServiceDetailElement), AddItemName = "WatcherServiceDetail")] public WatcherServiceDetailCollection<TWatcherServiceDetailElement> WatcherServiceDetails I'm aware that type parameters aren't allowed for attributes and that's what I want to know how to do.

• Migrating a simple application from Application Delegate to ViewController Class

  - by eco_bach

  Hi Frst of all wanted to send out a huge thanks for the great feedback and support. I have a simple application working, right now simply loads a sequence of images and alows the user to step thru the images by clicking a button. All of my logic is in my Application Delegate class, with the image loading, initialization of UIImage Views etc happening in my applicationDidFinishLaunching method. My next step is to migrate as much as possible all of the logic from this class to a ViewController, to take advantage of the extra functionality etc in viewcontrollers. All my images and imageViews are initialized like the following in my applicationDidFinishLaunching. img = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@image1.jpg" ofType:nil]]; imgView = [[UIImageView alloc] initWithImage:img]; How would I migrate this to a ViewController based application? Where would I put all of the logic currently in my applicationDidFinishLaunching method, or for loading of images, is it necessary to only load them here? Any feedback, tips, suggestions appreciated.

• How should it work if I want a page to have a theme-roller (more or less like the jQuery themeroller

  - by DanC

  The basic idea is to create a page that gives the user the ability to choose a skin or theme from a menu. When the user selects the desired skin/theme, it should be applied to the page, just like the jquery ui theme roller page. So, to be more precise, what I am trying to know is how to apply dynamically the style to a page - how to load the css and so forth. On the jquery ui theme roller, is there any javascript triggered after the new set of styles is loaded? (for js positioning or sizing?) (The answer may be simple as "just create a new style element and set its src"...) Just to be clear, I don't need the option to let users customize the UI, I want them just to be able to pick from a few pre set styles. Thanks!

• Can I access the function body of an event listener using nodeJS jsdom

  - by Zhami

  I am using jsdom with nodeJS. I load in a large HTML document, and am using jQuery to navigate the DOM. I have a case where I have an element, and I need to access the function body of an event listener (onclick). The event listener was added in the source HTML: <a href="#" onclick="javascript:window.open('http://<rest-of-url>'); return false;"></a> The onclick attribute of the DOM element is undefined. btw: what I really want to do is get the URL (please note that <rest-of-url> is not what is in the source, a real URL spec is there) that is specified in the source.

• Reading web-service information from assembly app.config file

  - by Benjamin Ortuzar

  I have a plugin architecture solution written in .NET C# 3.5, where each plug-in is an assembly loaded by the main project. Each plug-in connects to a different web-service, so I would like to have the configuration of that plugin in its own plugin.dll.config file instead of having it in the app.config of the main project. I have been looking around and I saw that i could load from each class its own config file: // Get the application configuration file. System.Configuration.Configuration config = ConfigurationManager.OpenMappedExeConfiguration(fileMap,userLevel) I see how that would help me get the basic settings from the appSettings section, but I cant see a way to read the web-service information stored in the plugin.dll.config file. Any help on how to approach this situation is very welcome.

• Adding business logic to a domain class using a getter style method name

  - by Richard Paul

  I'm attempting to add a method to a grails domain class, e.g. class Item { String name String getReversedName() { name.reverse() } } When I attempt to load the application using grails console I get the following error: Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory':Invocation of init method failed; nested exception is org.hibernate.PropertyNotFoundException: Could not find a setter for property reversedName in class Item ... 18 more It looks like Hibernate is interpreting getReversedName() as a getter for a property, however in this case it is a derived field and hence should not be persisted. Obviously in my actual code the business logic I'm exposing is more complex but it isn't relevant to this question. I want to be able to call item.reversedName in my code/gsps. How can I provide property (getter) access to a method in a Grails domain class without Grails attempting to map it with Hibernate?
