  • jquery hover not working in safari and chrome

    - by Nik
    I'm developing a site and I am implementing a jquery hover effect on some list items. It works perfectly in all browser except safari and chrome (mac and pc). For some reason the hover effect doesnt work on those to browsers. Here is the link link text I thought I would add the code just in case it helps (it also uses the color_library.js file that can be found in the head of the document). $(document).ready(function() { var originalBG = $("#menu li#Q_01","#menu li#Q_03","#menu li#Q_05","#menu li#Q_07","#menu li#Q_09","#menu li#Q_11","#menu li#Q_11").css("background-color"); var originalBG1 = $("#menu li").css("color"); var originalBG2 = $("#menu li#Q_02","#menu li#Q_04","#menu li#Q_06","#menu li#Q_08","#menu li#Q_10","#menu li#Q_12").css("background-color"); var fadeColor = "#009FDD"; var fadeColor1 = "#FFF"; var fadeColor2 = "#623A10"; $("#menu li#Q_01").hover( function () { $(this).animate( { backgroundColor:fadeColor2,color:fadeColor1}, 380 ) }, function () { $(this).animate( {color:"#666",backgroundColor:"#fff"}, 380 ) } ); $("#menu li#Q_03").hover( function () { $(this).animate( { backgroundColor:fadeColor2,color:fadeColor1}, 380 ) }, function () { $(this).animate( {color:"#666",backgroundColor:"#fff"}, 380 ) } ); $("#menu li#Q_05").hover( function () { $(this).animate( { backgroundColor:fadeColor2,color:fadeColor1}, 380 ) }, function () { $(this).animate( {color:"#666",backgroundColor:"#fff"}, 380 ) } ); $("#menu li#Q_07").hover( function () { $(this).animate( { backgroundColor:fadeColor2,color:fadeColor1}, 380 ) }, function () { $(this).animate( {color:"#666",backgroundColor:"#fff"}, 380 ) } ); $("#menu li#Q_09").hover( function () { $(this).animate( { backgroundColor:fadeColor2,color:fadeColor1}, 380 ) }, function () { $(this).animate( {color:"#666",backgroundColor:"#fff"}, 380 ) } ); $("#menu li#Q_11").hover( function () { $(this).animate( { backgroundColor:fadeColor2,color:fadeColor1}, 380 ) }, function () { $(this).animate( {color:"#666",backgroundColor:"#fff"}, 380 ) } ); $("#menu li#Q_13").hover( function () { $(this).animate( { backgroundColor:fadeColor2,color:fadeColor1}, 380 ) }, function () { $(this).animate( {color:"#666",backgroundColor:"#fff"}, 380 ) } ); $("#menu li#Q_02").hover( function () { $(this).animate( { backgroundColor:fadeColor,color:fadeColor1}, 380 ) }, function () { $(this).animate( {color:"#666",backgroundColor:"#fff"}, 380 ) } ); $("#menu li#Q_04").hover( function () { $(this).animate( { backgroundColor:fadeColor,color:fadeColor1}, 380 ) }, function () { $(this).animate( {color:"#666",backgroundColor:"#fff"}, 380 ) } ); $("#menu li#Q_06").hover( function () { $(this).animate( { backgroundColor:fadeColor,color:fadeColor1}, 380 ) }, function () { $(this).animate( {color:"#666",backgroundColor:"#fff"}, 380 ) } ); $("#menu li#Q_08").hover( function () { $(this).animate( { backgroundColor:fadeColor,color:fadeColor1}, 380 ) }, function () { $(this).animate( {color:"#666",backgroundColor:"#fff"}, 380 ) } ); $("#menu li#Q_10").hover( function () { $(this).animate( { backgroundColor:fadeColor,color:fadeColor1}, 380 ) }, function () { $(this).animate( {color:"#666",backgroundColor:"#fff"}, 380 ) } ); $("#menu li#Q_12").hover( function () { $(this).animate( { backgroundColor:fadeColor,color:fadeColor1}, 380 ) }, function () { $(this).animate( {color:"#666",backgroundColor:"#fff"}, 380 ) } ); }); Thanks for any advice ;)

  • flex blazeds spring exception translator

    - by Shah Al
    I am using spring exception translator to wrap java exception into flex exception. eg public void testException()throws Exception{ throw new Exception("my exception"); } But for some reason, I am getting IllegalAccessError. The code sections are entering the testException and the Translator class. Question: why it trying to get log target level ? Can someone help me resolve this please. Below is the lines from the log: MyExceptionTranslatorImpl.translate()class java.lang.IllegalAccessError MyExceptionTranslatorImpl.translate()java.lang.IllegalAccessError: tried to access method flex.messaging.log.Log.getTargetLevel()S from class flex.messaging.MessageException MyExceptionTranslatorImpl.translate()tried to access method flex.messaging.log.Log.getTargetLevel()S from class flex.messaging.MessageException [BlazeDS] tried to access method flex.messaging.log.Log.getTargetLevel()S from class flex.messaging.MessageException [BlazeDS] Serializing AMF/HTTP response

  • Javascript onbeforeunload Issue

    - by Nik
    Alright, I have an issue with the following code. What happens is when a user closes their browser, it should prompt them to either click OK or click CANCEL to leave the page. Clicking OK would trigger a window.location to redirect to another page for user tracking (and yes, to avoid flame wars, there is a secondary system in place to assure accurate tracking, in the event of the user killing the browser from the task manager (as mentioned in similar questions)). CANCEL would remain on the page, the issue being that no matter what button you hit, you get redirected as if you wanted to leave the page. The relevant code is below. window.onbeforeunload = confirmExit; function confirmExit() { var where_to = confirm("Click OK to exit, Click CANCEL to stay."); if (where_to == true) { window.location="logout.php"; } if (where_to == false){ alert("Returning..."); } }

  • Load Assembly in New AppDomain without loading it in Parent AppDomain

    - by Al Katawazi
    I am attempting to load a dll into a console app and then unload it and delete the file completely. The problem I am having is that the act of loading the dll in its own AppDomain creates a reference in the Parent AppDomain thus not allowing me to destroy the dll file unless I totally shut down the program. Any thoughts on making this code work? string fileLocation = @"C:\Collector.dll"; AppDomain domain = AppDomain.CreateDomain(fileLocation); domain.Load(@"Services.Collector"); AppDomain.Unload(domain); BTW I have also tried this code with no luck either string fileLocation = @"C:\Collector.dll"; byte[] assemblyFileBuffer = File.ReadAllBytes(fileLocation); AppDomainSetup domainSetup = new AppDomainSetup(); domainSetup.ApplicationBase = Environment.CurrentDirectory; domainSetup.ShadowCopyFiles = "true"; domainSetup.CachePath = Environment.CurrentDirectory; AppDomain tempAppDomain = AppDomain.CreateDomain("Services.Collector", AppDomain.CurrentDomain.Evidence, domainSetup); //Load up the temp assembly and do stuff Assembly projectAssembly = tempAppDomain.Load(assemblyFileBuffer); //Then I'm trying to clean up AppDomain.Unload(tempAppDomain); tempAppDomain = null; File.Delete(fileLocation);

    People use gdb on and off for debugging, of course there are lots of other debugging tools across the varied OSes, with and without GUI and, maybe other fancy IDE features. I would like to know what useful gdb scripts you have written and liked. While, I do not mean a dump of commands in a something.gdb file that you source to pull out a bunch of data, if that made your day, go ahead and talk about it. Lets think conditional processing, control loops and functions written for more elegant and refined programming to debug and, maybe even for whitebox testing Things get interesting when you start debugging remote systems (say, over a serial/ethernet interface) And, what if the target is a multi-processor (and, multithreaded) system Let me put a simple case as an example... Say, A script that traversed serially over entries to locate a bad entry in a large hash-table that is implemented on an embedded platform. That helped me debug a broken hash-table once.

  • Flex chart not displaying right values along x axis.

    - by Shah Al
    I don't know of any better way to ask this question. If the below code is run (i know the cData sections are not visible in the preview, something causes it to be ignored). The result does not represent the data correctly. 1. Flex ignores missing date 24 aug for DECKER. 2. It wrongly associates 42.77 to 23-Aug instead of 24-AUG. Is there a way in flex, where the x-axis is a union of all available points ? The below code is entirely from : Adobe website link I have only commented 2 data points. //{date:"23-Aug-05", close:45.74}, and //{date:"24-Aug-05", close:150.71}, <?xml version="1.0"?> [Bindable] public var SMITH:ArrayCollection = new ArrayCollection([ {date:"22-Aug-05", close:41.87}, //{date:"23-Aug-05", close:45.74}, {date:"24-Aug-05", close:42.77}, {date:"25-Aug-05", close:48.06}, ]); [Bindable] public var DECKER:ArrayCollection = new ArrayCollection([ {date:"22-Aug-05", close:157.59}, {date:"23-Aug-05", close:160.3}, //{date:"24-Aug-05", close:150.71}, {date:"25-Aug-05", close:156.88}, ]); [Bindable] public var deckerColor:Number = 0x224488; [Bindable] public var smithColor:Number = 0x884422; ]] <mx:horizontalAxisRenderers> <mx:AxisRenderer placement="bottom" axis="{h1}"/> </mx:horizontalAxisRenderers> <mx:verticalAxisRenderers> <mx:AxisRenderer placement="left" axis="{v1}"> <mx:axisStroke>{h1Stroke}</mx:axisStroke> </mx:AxisRenderer> <mx:AxisRenderer placement="left" axis="{v2}"> <mx:axisStroke>{h2Stroke}</mx:axisStroke> </mx:AxisRenderer> </mx:verticalAxisRenderers> <mx:series> <mx:ColumnSeries id="cs1" horizontalAxis="{h1}" dataProvider="{SMITH}" yField="close" displayName="SMITH" > <mx:fill> <mx:SolidColor color="{smithColor}"/> </mx:fill> <mx:verticalAxis> <mx:LinearAxis id="v1" minimum="40" maximum="50"/> </mx:verticalAxis> </mx:ColumnSeries> <mx:LineSeries id="cs2" horizontalAxis="{h1}" dataProvider="{DECKER}" yField="close" displayName="DECKER" > <mx:verticalAxis> <mx:LinearAxis id="v2" minimum="150" maximum="170"/> </mx:verticalAxis> <mx:lineStroke> <mx:Stroke color="{deckerColor}" weight="4" alpha="1" /> </mx:lineStroke> </mx:LineSeries> </mx:series> </mx:ColumnChart> <mx:Legend dataProvider="{myChart}"/>

  • Contributing to a Linux distribution

    - by Big Al
    I'm interested in contributing to a Linux distro, but regarding the various distro's developer communities, I'm having a bit of trouble figuring out which one I'd most like to join. What languages I know: C, C++, Lua, Python, and fairly familiar with Perl (though I wouldn't say I "know" it). In particular, I have very little experience with x86 assembly besides hacking stuff together for performance tweaks, though that will be partially rectified soon. What I'm looking for: A community that provides plenty of opportunities for developers to work on various aspects of the distribution. To be honest I'm most interested in reading and working on the kernel source (in which case the distro doesn't matter), but it's pretty daunting and I figure getting into the Linux community and working with experienced Linux developers might give me a better idea of how to jump into the guts(let me know if this is bogus, or if you have any advice regarding that). So... Which distro has the "best" developer community in terms of organization, people who are fun to work with, and opportunities to contribute? I've read various "Contributing to XXX" pages and mailing lists for distros like Ubuntu, OpenSuse, Fedora, etc. but I'd rather get a more personal testament from an actual developer.

  • MySQL & PHP Parameter 1 as Resource

  • updating rails to 2.3.6

    - by Nik
    can you update your 2.3.5 app with just "gem update rails" and change the version # in environment.rb? I did that and lots of errors came out like in console just typing Post.all would show "undefined method `retrieve_connection' for nil:NilClass". Any ideas? By the way, I have these gems in my environment.rb config.gem "aws-s3", :version = "= 0.6.2", :lib = "aws/s3" config.gem "less" config.gem "authlogic" config.gem "be9-acl9", :source = "http://gems.github.com", :lib = "acl9" config.gem "hash_extension" config.gem "prawn"

  • How do I read the manifest file for a webapp running in apache tomcat?

    - by Nik Reiman
    I have a webapp which contains a manifest file, in which I write the current version of my application during an ant build task. The manifest file is created correctly, but when I try to read it in during runtime, I get some strange side-effects. My code for reading in the manifest is something like this: InputStream manifestStream = Thread.currentThread() .getContextClassLoader() .getResourceAsStream("META-INFFFF/MANIFEST.MF"); try { Manifest manifest = new Manifest(manifestStream); Attributes attributes = manifest.getMainAttributes(); String impVersion = attributes.getValue("Implementation-Version"); mVersionString = impVersion; } catch(IOException ex) { logger.warn("Error while reading version: " + ex.getMessage()); } When I attach eclipse to tomcat, I see that the above code works, but it seems to get a different manifest file than the one I expected, which I can tell because the ant version and build timestamp are both different. Then, I put "META-INFFFF" in there, and the above code still works! This means that I'm reading some other manifest, not mine. I also tried this.getClass().getClassLoader().getResourceAsStream(...) But the result was the same. What's the proper way to read the manifest file from inside of a webapp running in tomcat? Edit: Thanks for the suggestions so far. Also, I should note that I am running tomcat standalone; I launch it from the command line, and then attach to the running instance in Eclipse's debugger. That shouldn't make a difference, should it?

    I am building a website in which this website will be focused on the publishing of novels. Every writers who publish their novels with us will get a royalty from us. And this royalty comes from the user or the reader who read the novel online in our website. When a user search for a novel and want to read that, they will click a link to the page which its content is that novel. The html page for each novels will have a session function that first will force them to login or register to make a payment such as with a credit-card or paypal before accessing that html page. My problem now is if the user has succesfully login and access the html page, I am afraid if the user will copy the content of the novel. Some disccussion out here How to Disable Copy Paste (Browser) have a solution to create it in Flash so that it can't be coppied-paste. But the I think, if the user who access it is a web developer like us they will try to find the path of the file from the link in the page source, and then they can steal it. For now I think it is enough I am explaining this. I hope anyone fully accept this problem (question) with a good idea to solve it.

  • Why does Font.registerFont throw an error the second time a swf is loaded?

    - by Al Brown
    I've found an issue (in flash cs5) when using TLFTextfields and fonts shared at runtime, and I wondered if anyone has a solution. Here's the scenario. Fonts.swf: library for fonts (runtime shared DF4) Popup.swf: popup with a TLFTextfield (with text in it) using a font from Fonts.swf Main.swf : the main swf with a button that loads and unloads Popup.swf (using Loader or SafeLoader give the same results) Nice and simple, Run main.swf, click button and the popup appears with the text. Click the button again to remove the popup. All well and good now click the button again and I get the following error. ArgumentError: Error #1508: The value specified for argument font is invalid. at flash.text::Font$/registerFont() at Popup_fla::MainTimeline()[Popup_fla.MainTimeline::MainTimeline:12] I'm presuming it's happening because the font is already registered (checked when clicking before the load). Does anyone know how to get past this? If you are wondering here's my Main.as package { import fl.controls.Button; import flash.display.Loader; import flash.display.Sprite; import flash.events.Event; import flash.events.IOErrorEvent; import flash.events.MouseEvent; import flash.events.UncaughtErrorEvent; import flash.net.URLRequest; import flash.text.Font; public class Main extends Sprite { public var testPopupBtn:Button; protected var loader:Loader; public function Main() { trace("Main.Main()"); testPopupBtn.label = "open"; testPopupBtn.addEventListener(MouseEvent.CLICK, testClickHandler); } protected function testClickHandler(event:MouseEvent):void { trace("Main.testClickHandler(event)"); if(loader) { testPopupBtn.label = "open"; this.removeChild(loader); //loader.unloadAndStop(); loader = null; }else{ testPopupBtn.label = "close"; trace("Registered Fonts -->"); var fonts:Array = Font.enumerateFonts(false); for each (var font:Font in fonts) { trace("\t",font.fontName, font.fontStyle, font.fontType); } trace("<--"); loader = new Loader(); loader.uncaughtErrorEvents.addEventListener(UncaughtErrorEvent.UNCAUGHT_ERROR, uncaughtErrorHandler); this.addChild(loader); try{ loader.load(new URLRequest("Popup.swf")); }catch(e:*){ trace(e); } } } private function uncaughtErrorHandler(event:UncaughtErrorEvent):void { trace("Main.uncaughtErrorHandler(event)", event); } } }

  • Using LCD with Arduino

    - by Nik
    Hi, Is it possible to use any LCD with arduino or I need to stick to some for which the libraries are available. I'm just starting out with arduino and know nothing about interfacing LCDs with arduino. I'm planing to buy Old IPhone LCD as they are cheap and big enough to do something useful with them. Also to use iPhone LCD do I need to add some extra circuit or directly plugging iPhone LCD into arduino will work? I don't care about the touch feature right now.
