  • Pass object from JSON into MVC Controller - its always null ?

    - by SteveCl
    Hi I have seen a few questions on here related to the a similar issue, I have read them, followed them, but still i have the same problem. I am basically creating an object in javascript and trying to call a method on the controller that will return a string of html. Not JSON. I've been playing around with dataType and contentType but still no joy. So apologies if the code snippets are a bit messy. Build the object in JS. function GetCardModel() { var card = {}; card.CardTitle = $("#CardTitle").val(); card.TopicTitle = $("#TopicTitle").val(); card.TopicBody = $("#TopicBody").data("tEditor").value(); card.CardClose = $("#CardClose").val(); card.CardFromName = $("#CardFromName").val(); return card; } Take a look at the object - all looks good and as it should in JSON. var model = GetCardModel(); alert(JSON.stringify(GetCardModel())); Make the call... $.ajax({ type: "POST", url: "/Postcard/Create/Preview/", dataType: "json", //contentType: "application/json", date: GetCardModel(), processData: true, success: function (data) { alert("im back"); alert(data); }, error: function (xhr, ajaxOptions, error) { alert(xhr.status); alert("Error: " + xhr.responseText); //alert(error); } }); Always when I step into the controller, the object is ALWAYS there, but with null values for all the properties.

  • nservicebus deleting subscription record after inserting it?

    - by Justin Holbrook
    I have been playing with nservicebus for a few weeks now and since everything was going well on my local machine I decided to try to set up a test environment and work on deployment. I am using the generic host that comes with nservicebus and was using the nservicebus.Integration profile when running locally, but would like to use Nservicebus.Production in the test environment. I set up a sql server 2008 database, made changes to my app.config and everything seemed to work fine. But after a few attempts, I noticed messages were not being picked up by my subscriber. I checked the subscription table and it was empty. Upon examination of the logs I noticed the following: 2010-05-06 15:07:57,416 [1] DEBUG NHibernate.Persister.Entity.AbstractEntityPers ister [(null)] <(null) - Insert 0: INSERT INTO [Subscription] (SubscriberEndpo int, MessageType) VALUES (?, ?) 2010-05-06 15:07:57,416 [1] DEBUG NHibernate.Persister.Entity.AbstractEntityPers ister [(null)] <(null) - Update 0: 2010-05-06 15:07:57,416 [1] DEBUG NHibernate.Persister.Entity.AbstractEntityPers ister [(null)] <(null) - Delete 0: DELETE FROM [Subscription] WHERE Subscriber Endpoint = ? AND MessageType = ? Why would it insert then delete my subscription right afterwards? To try to rule out a nhibernate dialect issue I tried switching my subscription storage to an oracle 10g database. It behaved exactly the same, it worked the first 2 times, then I started seeing my subscriptions being deleted right after they were inserted. Any ideas what is causing this behavior?

  • Composing adaptors in Boost::range

    - by bruno nery
    I started playing with Boost::Range in order to have a pipeline of lazy transforms in C++]1. My problem now is how to split a pipeline in smaller parts. Suppose I have: int main(){ auto map = boost::adaptors::transformed; // shorten the name auto sink = generate(1) | map([](int x){ return 2*x; }) | map([](int x){ return x+1; }) | map([](int x){ return 3*x; }); for(auto i : sink) std::cout << i << "\n"; } And I want to replace the first two maps with a magic_transform, i.e.: int main(){ auto map = boost::adaptors::transformed; // shorten the name auto sink = generate(1) | magic_transform() | map([](int x){ return 3*x; }); for(auto i : sink) std::cout << i << "\n"; } How would one write magic_transform? I looked up Boost::Range's documentation, but I can't get a good grasp of it.

  • Play playlist with MediaPlayer

    - by Kaloer
    Hi, I'm trying to play a playlist I get using the MediaStore provider. However, when I try playing a playlist nothing happens. Can a MediaPlayer play a playlist (m3u file) and do I need to set the first track to play ? This is my test code in the onCreate() method: Uri uri = MediaStore.Audio.Playlists.EXTERNAL_CONTENT_URI; if(uri == null) { Log.e("Uri = null"); } String[] projection = new String[] { MediaStore.Audio.Playlists._ID, MediaStore.Audio.Playlists.NAME, MediaStore.Audio.Playlists.DATA }; Cursor c = managedQuery(uri, projection, null, null, null); if(c == null) { Toast.makeText(getApplicationContext(), R.string.alarm_tone_picker_error, Toast.LENGTH_LONG).show(); return; } if(!c.moveToFirst()) { c.close(); Toast.makeText(getApplicationContext(), R.string.alarm_tone_picker_no_music, Toast.LENGTH_LONG).show(); return; } c.moveToFirst(); try { MediaPlayer player = new MediaPlayer(); player.setDataSource(c.getString(2)); player.start(); } catch(Exception e) { e.printStackTrace(); } I have turned on every volume stream. Thanks you, Kaloer

  • Should nested attributes be automatically deleted when I delete the parent record?

    - by brad
    I'm playing around with nested forms in attributes and have a model Invoice that has_many invoice_phone_numbers. I have the following line in my invoice.rb model file accepts_nested_attributes_for :invoice_phone_numbers, :allow_destroy => true, :reject_if => proc { |attrs| attrs.all? { |k, v| v.blank? } } This does what it should and I can delete invoice_phone_numbers from the form by selecting their 'delete' checkbox. But when I delete an Invoice, I have noticed that the nested invoice_phone_numbers are not also deleted. This causes problems as rails seems to reuse id numbers in the Invoice model (Should it? Does this depend on the database? I'm using SQLite3) so phone numbers from previous invoices turn up in new invoices after they have been created. Anyway, my question is should the nested attributes be deleted when I delete the parent attribute? Is there a way to make this happen automatically as part of the nesting process or do I need to deal with this in my invoice model? If so, what is the best way to do this? I would try to go about this with a before_destroy callback but want to know if this is the best way to do this. Anyway, thanks.

  • Activator.CreateInstance uses a huge amount of memory

    - by Marco
    I have been playing a bit with Silverlight and try to port my Silverlight 3.0 application to Silverlight 4.0. My application loads different XAP files and upon a user request create an instance of a Xaml user control and adds it to the main container, in a sort of MEF approach in order I can have an extensible and pluggable application. The application is pretty huge and to keep acceptable the performances and the initial loading I have built up some helper classes to load in the background all pages and user controls that might be used later on. On Silverlight 3.0 everything was running smoothly without any problem so far. Switching to SL 4.0 I have noticed that when the process approaches to create the instances of the user controls using Activator.CreateInstance, the layout freezes unexpectedly for a minute and sometimes for more. Looking at the task manager the memory usage of IE jumps from 50MB to 400MB and sometimes to 1.5 GB. If the process won't take that much the layout is rendered properly and the memory falls back to 50 MB. Otherwise everything crashes due to out of memory exeption. Does anybody encountered the same problem? Or has anybody a solution about this tricky issue?

  • Speed comparison - Template specialization vs. Virtual Function vs. If-Statement

    - by Person
    Just to get it out of the way... Premature optimization is the root of all evil Make use of OOP etc. I understand. Just looking for some advice regarding the speed of certain operations that I can store in my grey matter for future reference. Say you have an Animation class. An animation can be looped (plays over and over) or not looped (plays once), it may have unique frame times or not, etc. Let's say there are 3 of these "either or" attributes. Note that any method of the Animation class will at most check for one of these (i.e. this isn't a case of a giant branch of if-elseif). Here are some options. 1) Give it boolean members for the attributes given above, and use an if statement to check against them when playing the animation to perform the appropriate action. Problem: Conditional checked every single time the animation is played. 2) Make a base animation class, and derive other animations classes such as LoopedAnimation and AnimationUniqueFrames, etc. Problem: Vtable check upon every call to play the animation given that you have something like a vector<Animation>. Also, making a separate class for all of the possible combinations seems code bloaty. 3) Use template specialization, and specialize those functions that depend on those attributes. Like template<bool looped, bool uniqueFrameTimes> class Animation. Problem: The problem with this is that you couldn't just have a vector<Animation> for something's animations. Could also be bloaty. I'm wondering what kind of speed each of these options offer? I'm particularly interested in the 1st and 2nd option because the 3rd doesn't allow one to iterate through a general container of Animations. In short, what is faster - a vtable fetch or a conditional?

  • facebook Hacker cup: studious Student problem.

    - by smartmuki
    During the qualification round, the following question was asked: You've been given a list of words to study and memorize. Being a diligent student of language and the arts, you've decided to not study them at all and instead make up pointless games based on them. One game you've come up with is to see how you can concatenate the words to generate the lexicographically lowest possible string. Input As input for playing this game you will receive a text file containing an integer N, the number of word sets you need to play your game against. This will be followed by N word sets, each starting with an integer M, the number of words in the set, followed by M words. All tokens in the input will be separated by some whitespace and, aside from N and M, will consist entirely of lowercase letters. Output Your submission should contain the lexicographically shortest strings for each corresponding word set, one per line and in order. Constraints 1 <= N <= 100 1 <= M <= 9 1 <= all word lengths <= 10 Example input 5 6 facebook hacker cup for studious students 5 k duz q rc lvraw 5 mybea zdr yubx xe dyroiy 5 jibw ji jp bw jibw 5 uiuy hopji li j dcyi Example output cupfacebookforhackerstudentsstudious duzklvrawqrc dyroiymybeaxeyubxzdr bwjibwjibwjijp dcyihopjijliuiuy The program I wrote goes as: chomp($numberElements=<STDIN>); for(my $i=0; $i < $numberElements; $i++) { my $string; chomp ($string = <STDIN>); my @array=split(/\s+/,$string); my $number=shift @array; @sorted=sort @array; $sortedStr=join("",@sorted); push(@data,$sortedStr); } foreach (@data) { print "$_\n"; } The program gives the correct output for the given test cases but still facebook shows it to be incorrect.

    Hello, I'm playing around with YouTubes Javascript API. I've set up a test page on my local enviornment, but the play function is not working. The video loads, and I can press play on the yt video screen, but my link "play" isn't working. Can someone tell me what I'm doing wrong??

  • Organising files and classes in XCode (iPhone application)

    - by pulegium
    It's a generic question and really a newbie one too, so bear with me... I'm playing with some iPhone development, and trying to create a simple "flip type" application. Nothing sophisticated, let's say on the flip side is a short application summary, bit like 'help' and on the main screen is a simple board game, let's say tic-tac-toe or similar. Now, XCode has generated me 'Main View', 'Flipside View' and 'Application Delegate' folders, with default template files in them. Now the question is where do I create appropriate 'MVC' classes? Let's say (V)iew classes are going to be the ones that have been automatically created. So the Flipside view class is responsible for generating text/images etc on the 'help' view. 'Main View' class is what draws the items on the table and updates the counters, etc. Where should I place the 'controller' class? And also, should it only be dealing with proxying only to the model? According to this the controller method is called from the view and manipulates the method classes. Similarly, the results from model are passed back to the view class by the controller issuing the calls to appropriate view methods. Similarly, where does the model class go? or should I just create a new folder for each, controller and model class files? What I'm after is the best practices, or just a short description how people normally structure their applications. I know it's very specific and also undefined... I came from Django background, so the way stuff is organised there is slightly different. Hope this makes sense, sorry if it's all bit vague, but I have to start somewhere :) And yes I've read quite few docs on the apple developer site, but trouble is that the documents are either going into too much detail about the language/framework/etc and the examples are way too simplistic. Actually, this leads me to the final question, has anyone know any good example of relatively complete application tutorial which I could use as a reference in organising my files?...

  • Flash Player: Any remedy for the stale video image data problem (in a reused NetStream object)?

    - by amn
    Has anyone experienced stale stills of a previous playback for a reused NetStream object? If so, what are the workarounds for this, except re-creating the object (which eats performance and time)? It is hard to reuse NetStream objects because of a (in my opinion) fundamental issue with NetStream objects - when you 'close' a playing stream and at a later point issue a 'play' call on it again with a different name, the stream appears to still contain a stale image lingering from previous playback, and this is of course displayed in the Video object for a moment - the moment I assume it takes for new stream data to become available from server. Because of this behavior, to improve my users' visual experience, I simply discard a NetStream object after a playback session, and assign a new NetStream object to the same variable, set it up, and play something else. It appears to work - no stale image - but what bugs me is that it's a work around and costs performance (construction and setting up the object again - event listeners and 'client' delegates and more memory usage - NetStream objects are not garbage collected immediately, it takes some time). It would be really nice to REALLY be able to reuse a stream. I am thinking of something akin to Video.clear method, but for the NetStream class. Am I missing something?

  • Can the Visual Studio (2010) Command Window handle "external tools" with project/solution relative p

    - by ee
    I have been playing with the Command Window in Visual Studio (View-Other Windows-Command Window). It is great for several mouse-free scenarios. (The autocompleting file "Open" command rocks in a non-trivial solution.) That success got me thinking and experimenting: Possibility 1.1: You can use the Alias commands to create custom commands Possibility 1.2: You can use the Shell command to run arbitrary executables and specify parameters (and pipe the result to the output or command windows) Possibility 2: A previously setup external tool definition (with project-relative path variables) could be run from the command window What I am stuck on is: There doesn't appear to be a way to send parameters to an aliased command (and thus the underlying Shell call) There doesn't appear to be a way to use project/solution relative paths ($SolutionDir/$ProjectDir) on a Shell call Using absolute paths in Shell works, but is fragile and high-maintenance (one alias for each needed use case). Typically you want the command to run against a file relative to your project/solution. It seems you can't run the traditional external tools (Tools-External Tools...) in the command window Ultimately I want the external tool functionality in the command window in some way. Can anyone see a way to do this? Or am I barking up the wrong tree? So my questions: Can an "external tool" of some sort (using relative project/solution path parameters) be used in the Command Window? If yes, How? If no, what might be a suitable alternative?

  • Using $.post for simple ajax test, what am I missing?

    - by Cortopasta
    Playing with jquery for the first time, and I'm trying to get a simple AJAX set up working so I can better understand how things work. Unfortunately, I don't know a whole lot. Here's the HTML with the script: <html> <head> <title>AJAX attempt with jQuery</title> <script type="text/javascript" src="jquery.js"></script> <script type="text/javascript"> function ajax(str){ $("document").ready(function(){ $.post("ajaxjquerytest.php",str,function(){ $("p").html(response); }); }); </script> </head> <body> <input type="text" onchange="ajax(this.value)"></input> <p>Age?</p> </body> </html> And here is the PHP it's talking to: <?php $age = $_POST['age']; if ($age < 30) { echo "Young"; } else if ($age > 30) { echo "Old"; } else { echo "you're 30"; } ?>

  • How do I compare two PropertyInfos or methods reliably?

    - by Rob Ashton
    Same for methods too: I am given two instances of PropertyInfo or methods which have been extracted from the class they sit on via GetProperty or GetMember etc, (or from a MemberExpression maybe). I want to determine if they are in fact referring to the same Property or the same Method so (propertyOne == propertyTwo) or (methodOne == methodTwo) Clearly that isn't going to actually work, you might be looking at the same property, but it might have been extracted from different levels of the class hierarchy (in which case generally, propertyOne != propertyTwo) Of course, I could look at DeclaringType, and re-request the property, but this starts getting a bit confusing when you start thinking about Properties/Methods declared on interfaces and implemented on classes Properties/Methods declared on a base class (virtually) and overridden on derived classes Properties/Methods declared on a base class, overridden with 'new' (in IL world this is nothing special iirc) At the end of the day, I just want to be able to do an intelligent equality check between two properties or two methods, I'm 80% sure that the above bullet points don't cover all of the edge cases, and while I could just sit down, write a bunch of tests and start playing about, I'm well aware that my low level knowledge of how these concepts are actually implemented is not excellent, and I'm hoping this is an already answered topic and I just suck at searching. The best answer would give me a couple of methods that achieve the above, explaining what edge cases have been taken care of and why :-)

  • How to lazy load a data structure (python)

    - by Anton Geraschenko
    I have some way of building a data structure (out of some file contents, say): def loadfile(FILE): return # some data structure created from the contents of FILE So I can do things like puppies = loadfile("puppies.csv") # wait for loadfile to work kitties = loadfile("kitties.csv") # wait some more print len(puppies) print puppies[32] In the above example, I wasted a bunch of time actually reading kitties.csv and creating a data structure that I never used. I'd like to avoid that waste without constantly checking if not kitties whenever I want to do something. I'd like to be able to do puppies = lazyload("puppies.csv") # instant kitties = lazyload("kitties.csv") # instant print len(puppies) # wait for loadfile print puppies[32] So if I don't ever try to do anything with kitties, loadfile("kitties.csv") never gets called. Is there some standard way to do this? After playing around with it for a bit, I produced the following solution, which appears to work correctly and is quite brief. Are there some alternatives? Are there drawbacks to using this approach that I should keep in mind? class lazyload: def __init__(self,FILE): self.FILE = FILE self.F = None def __getattr__(self,name): if not self.F: print "loading %s" % self.FILE self.F = loadfile(self.FILE) return object.__getattribute__(self.F, name) What might be even better is if something like this worked: class lazyload: def __init__(self,FILE): self.FILE = FILE def __getattr__(self,name): self = loadfile(self.FILE) # this never gets called again # since self is no longer a # lazyload instance return object.__getattribute__(self, name) But this doesn't work because self is local. It actually ends up calling loadfile every time you do anything.

  • Calculations on the iteration count in for loop in Ruby 1.8.7

    - by user1805035
    I was playing around with Ruby and Latex to create a color coding set. I'm more than a novice with C++, but haven't looked at Ruby until now. So, still learning a lot of coding. I have the following block of code below. When attempting to run this, band1 = 1e+02. I've tried band1 = (BigDecimal(i) * 100).to_f thinking maybe there was some odd floating point issue. This is just me trying anything though as an integer multiplied by an integer should create an integer, if I'm still thinking correctly. I've tried a variety of other things as well (things that I can do in C++, but this ain't C++), but to no avail. (1..9).each do |i| #Band 1 (0..9).each do |j| #Band 2 (0..11).each do |k| #Band 3 #Band 3 Start #these are the colors of the resistor bands b1 = $c_band12[i] b2 = $c_band12[j] b3 = $c_band3[k] b4 = "Gold" oms = ((i*100) + (j*10)) * $mult[k] band1 = i*100 band2 = j band3 = $mult[k] end end end Not sure what I'm missing. Should I be using .each_with_index through these iterations? I've tried this: (1..9).each_with_index {|i, indexi| #Band 1 (0..9).each_with_index {|j, indexj| #Band 2 (0..11).each_with_index {|k, indexk| #Band 3 #Band 3 Start #these are the colors of the resistor bands b1 = $c_band12[i] b2 = $c_band12[j] b3 = $c_band3[k] b4 = "Gold" oms = ((i*100) + (j*10)) * $mult[k] band1 = indexk * 100 and I get the same answer. I can't see why 1*100 should equate to such a large number? Thank you, AT

  • Creating a clickable progress bar

    - by Cory
    What I'm essentially building is a webkit based controller that communicates with a program called Ecoute.app. The controller has a progressbar that indicates the progress made through the currently playing song, but I want to make this bar's position adjustable with a click. function barClick() { var progress = Ecoute.playerPosition(); var width = 142.5; var percentElapsed = progress / length; var position = width * percentElapsed; Ecoute.setPlayerPosition(position); } Is what I have, with Ecoute.playerPosition() returning the player's current position. Width has previously been defined as a dynamic value at var width = 142.5 / length * progress + 1.63; With length being the current track length and progress being the player's position. This has been able to dynamically stretch a progression overlay image to indicate the position of the track via the desktop controller. However, the max width used in the second function does not appear to allow the first function to work properly. Any help possibly determining the correct value or approach would be hugely appreciated.

  • At what point is it worth using a database?

    - by radix07
    I have a question relating to databases and at what point is worth diving into one. I am primarily an embedded engineer, but I am writing an application using QT to interface with our controller. We are at an odd point where we have enough data that it would be feasible to implement a database (around 700+ items and growing) to manage everything, but I am not sure it is worth the time right now to deal with. I have no problems implementing the GUI with files generated from excel and parsed in, but it gets tedious and hard to track even with VBA scripts. I have been playing around with converting our data into something more manageable for the application side with Microsoft Access and that seems to be working well. If that works out I am only a step (or several) away from using an SQL database and using the QT library to access and modify it. I don't have much experience managing data at this level and am curious what may be the best way to approach this. So what are some of the real benefits of using a database if any in this case? I realize much of this can be very application specific, but some general ideas and suggestions on how to straddle the embedded/application programming line would be helpful. Thanks

  • codeigniter differentiate field names in JOINed tables

    - by Patrick
    Hi, I need to retrieve data from two tables. the first is a list of events, the second is a list of venues. I have a fields with the same name in both tables: events.venue (which is an ID) and venues.venue is the name of the place, say "blues bar". The tables can be joined on events.venue = venues.id. Snippet of my model: $this->db->select('events.*, venues.*'); $this->db->join('venues', 'events.venue = venues.id'); if ($date != 'all') { $this->db->where('date', $date); } if ($keyword) { $this->db->like('description', $keyword); $this->db->or_like('band', $keyword); $this->db->or_like('venue', $keyword); $this->db->or_like('genre', $keyword); } $Q = $this->db->get('events'); if ($Q->num_rows() > 0) { foreach ($Q->result() as $row) { $data[] = $row; } } $Q->free_result(); return $data; Snippet of the View: foreach ($events as $row) { echo "<p>{$row->band} ({$row->genre})<br />"; echo "Playing at: {$row->venue}<br /></p>"; // echoes "blues bar" //more here... } 2 Questions: 1) Why does $row-venue echo venues.venue, instead of events.venue? B) how can I differentiate them? eg. What if I want to echo both events.venue and venues.venue? I can probably do something like "SELECT venues.venue as name_of_the_venue", but how can I do this when I've already selected *?

    Folks, I need your knowledge here. Think about the following sittuation - my app need to set my iphone to vibrate mode on a certain time and get it back to playing sounds mode (for call receiving, sms, email, all common sound notifications) some minutes later. I've already googled that, and didn't find a good, apple accetable way of doing that: http://stackoverflow.com/questions/736047/possible-to-programmatically-open-settings-app-from-iphone http://stackoverflow.com/questions/702319/is-it-possible-to-dynamically-alter-an-iphone-apps-settings-page-in-the-settings http://stackoverflow.com/questions/1141391/display-iphone-application-settings-within-your-application http://stackoverflow.com/questions/335965/how-do-i-launch-my-settings-bundle-from-my-application [This one here is interesting, as fas I as find a way to know what is the key for the settings I'm interested in] http://stackoverflow.com/questions/335965/how-do-i-launch-my-settings-bundle-from-my-application [It mentions I can do that, but does not give an idea of how =(] http://stackoverflow.com/questions/702319/is-it-possible-to-dynamically-alter-an-iphone-apps-settings-page-in-the-settings [If this is true, I wouldn't be able to do what I want...] Does anyone there has an idea of how do I do that via app? Many thanks in advance.

  • Align child element to bottom with CSS

    - by alex
    I have a form input, and the label spans multiple lines, and I want the corresponding checkbox to appear at the bottom (last line of the label element). Here is what I was playing with CSS .standard-form { width: 500px; border: 1px solid red; } .standard-form .input-row { overflow: hidden; margin-bottom: 0.8em; } .standard-form label { width: 25%; float: left; } .standard-form .input-container { width: 70%; float: right; } .standard-form .checkbox .input-container { display: table-cell; height: 100%; vertical-align: text-bottom; } HTML <form class="standard-form"> <div class="input-row checkbox" id="permission"> <label for="input-permission"> Do I hereby grant you permission to do whatever tasks are neccessary to achieve an ideal outcome? </label> <div class="input-container"> <input type="checkbox" id="input-permission" name="permission" value="true" /> </div> </div> </form> It is also online at JSbin. Is there any way to do this? I notice that div.input-container isn't expanding, which is the old multi column problem with CSS. I thought I could get this going with display: table-cell and vertical-align: bottom but I haven't been able to do it yet. I don't mind that IE6/7 won't render it correctly.

  • C++ AI Design Question

    - by disney
    Hi, I am currently writing a bot for a MMORPG. Though, currently I am stuck at trying to figure out how to nicely implement this. The design problem is related to casting the character spells in the correct order. Here is a simple example to what I need to archieve. It's not related to casting them, but doing it in the correct order. I would know how simply cast them randomly, by checking which skill has not yet been casted, but in right order as being shown in the GUI, not really. note: the skill amount may differ, it's not always 3, maximum 10 though. Charactername < foobar has 3 skills. Skill 1: Name ( random1 ) cooldown ( 1000 ms ) cast duration ( 500 ms ) Skill 2: Name ( random2 ) cooldown ( 1500 ms ) cast duration ( 700 ms ) Skill 3: Name ( random3 ) cooldown ( 2000 ms ) cast duration ( 900 ms ) I don't really know how I could implement this, if anyone has some thoughts, feel free to share. I do know that most of the people don't like the idea of cheating in games, I don't like it either, nor I am actually playing the game, but its an interesting field for me. Thank you.

  • Overlapping audio in IE when I show/hide videos

    - by user1062448
    I have a thumbnail list with links to individual videos. Everything works fine in all browsers but IE. In IE, if I start a video and (without slicking pause or stop) click on the thumbnail for the next video, the audio continues playing. In other words, the audio for both videos plays at once. Any suggestions? HTML: <ul class="videoButtons"> <li><a class="vidButton" href="javascript:void(0)" id="1" ><img src="images/videoPics/vid1Thumb.jpg" /><br />video title</a></li> <li><a class="vidButton" href="javascript:void(0)" id="2" ><img src="images/videoPics/vid2Thumb.jpg" /><br />video title</a></li> <li><a class="vidButton" href="javascript:void(0)" id="3" ><img src="images/videoPics/vid3Thumb.jpg" /><br />video title</a></li> </ul> <div class="box" id="video1"> <!--flv embedded object - FLVPlayer--> </div> <div class="box" id="video2"> <!--flv embedded object - FLVPlayer1--> </div> <div class="box" id="video3"> <!--flv embedded object - FLVPlayer2--> </div> Show/Hide code: $(".vidButton").click(function() { var buttonID = $(this).attr('id'); // get ID of the button clicked var video = $('#'+'video'+buttonID); // add ID number to video $('.box').hide(); // hide all other divs video.fadeTo("slow", 1); // show video }); }); // video objects swfobject.registerObject("FLVPlayer"); swfobject.registerObject("FLVPlayer1"); swfobject.registerObject("FLVPlayer2");
