  • jQuery/Javascript problem with IE

    - by Shadyn
    I have two radio buttons each with a unique ID. When one is clicked, I would like to add $10 to a total. When the other is clicked, we go back to the original total price. My jquery looks like this: function check_ceu() { var price = <%= conference_price %>; if($('#ceu_yes').is(':checked')){ $('#total').val(parseFloat(price) + 10) } else{ $('#total').val(price) } } I have this function bound to document.ready (for page refreshes) and also the onchange handler of the radio buttons. In FF and Chrome this works fine. In IE, when the radio button with ID of "ceu_yes" is checked nothing happens, then when clicking back to the other radio button, 10 is added. So in essence, IE has the checkbox functionality reversed. Below is my code for the buttons: <input type="radio" name="ceu" id="ceu_yes" value="1" onchange="check_ceu()" /> $10 <input type="radio" name="ceu" id="ceu_no" value="0" checked="checked" onchange="check_ceu()" /> No, thank you Any ideas on this?

  • Is it possible to create a Service that listens for hardware key presses?

    - by VoteBrian
    I'd like to run an Android background service that will act as a keylistener from the home screen or when the phone is asleep. Is this possible? From semi-related examples online, I put together the following service, but get the error, "onKeyDown is undefined for the type Service" public class ServiceName extends Service { @Override public void onCreate() { //Stuff } public IBinder onBind(Intent intent) { //Stuff return null; } @Override public boolean onKeyDown(int keyCode, KeyEvent event) { if(event.getAction() == KeyEvent.ACTION_DOWN) { switch(keyCode) { case KeyEvent.KEYCODE_A: //Stuff return true; case KeyEvent.KEYCODE_B: //Stuff return true; //etc. } } return super.onKeyDown(keyCode, event); } } I realize Android defaults to the search bar when you type from the home screen, but this really is just for a very particular use. I don't really expect to distribute this. Also, it'd be nice to use the camera button to wake the phone.

  • Form POST or sessions?

    - by eddienotizzard
    If you have an item where you allow users to add comments, how can you pass which item the user is replying too? I've though of using a hidden field in a form, however this can be easily changed using plugins such as firebug: <form method="post" action="blah"> <input type="hidden" name="item_id" value="<?php echo $item_id; ?>"> <!-- other form data here --> <input type="submit" name="submit"> </form> Or just simply using a session: $_SESSION['item_id'] = $item_id Is there a safe way to send the item data in a form?

  • youtube video will not display in desktop Chrome

    - by mwalrath
    Youtube video does not show up in a modal window when viewed in a desktop version of Chrome. The modal window pops up but the youtube video does not. https://animalhealth.pfizer.com/sites/pahweb/US/EN/Products/Pages/ClarifideStories.aspx It works in IE and Firefox on Windows7, works in Chrome on Android ICS and iOS6 iPad. It is on a sharepoint site but if I open a version saved to my desktop it works fine in chrome. I am using jquery fancybox How it is called <a class="iframe" href="http://www.youtube.com/watch? v=nGAyZSFDYh0&feature=player_embedded#at=41" style=" float: left;"> javascript <script type="text/javascript"> $(".iframe").click(function() { $.fancybox({ 'padding' : 0, 'autoScale' : false, 'transitionIn' : 'none', 'transitionOut' : 'none', 'title' : this.title, 'width' : 680, 'height' : 495, 'href' : this.href.replace(new RegExp("watch\\?v=", "i"), 'v/'), 'type' : 'swf', 'swf' : { 'wmode' : 'transparent', 'allowfullscreen' : 'true' } }); return false; }); </script>

    - by tgguy
    I created a Java LinkedBlockingQueue like new LinkedBlockingQueue(1) to limit the size of the queue to 1. However, in my testing, this seems to be ignored and there is often several things in the queue at any given time. Why is this?

  • Count function calls by name or signature. Gcc, C++

    - by MajesticRa
    I have some c++ written package. Linux, gcc. I can modify compilation process (change Makefile, flags, etc.), but can not change C++ source code. One runs the package with different parameters, it does a job and exits. How to count: 1) Number of calls of function with specific name? 2) Number of calls of functions with specific signature? 3) Number of calls of functions where one of the parameters is of specific type i.e. std::string (type is specified by signature)? 4) and extra Number of calls of functions of STL objects, i.e. std::string copy constructor? (I mean count a number of calls during the run. ) I thought to do it with GDB, but I found it very tough to do (1) and have not found how to do (2)-(4) at all. All acceptable answers I will write here for humanity.

  • How do I Capture native (Menu) button presses in PhoneGap?

    - by Dinedal
    By calling "BackButton.override();" and then hooking on to the backKeyDown event, I am able to get the back button press to register. But there doesn't appear to be a "MenuButton.override();" Also, hooking on the menuKeyDown doesn't register a button press. Here's my (non-functional) code. What am I missing? <script type="text/javascript" charset="utf-8" src="phonegap.js"></script> <script type="text/javascript" charset="utf-8"> document.addEventListener("deviceready", function() { alert('initialized'); }, false); document.addEventListener("menuKeyDown", function() { alert('menu_pressed'); // Never happens }, false); </script>

  • Firefox Back Button is occaisionally breaking the back button.

    - by Webjedi
    Having a really frustrating time with Firefox and the back button...given this simple ASP form: <head> <title>Form 1</title> </head> <body> <form action="form2.asp" method="post"> Enter some text:<input type="text" name="thetext" id="thetext"> <input type="submit" id="submit" name="submit"> </form> </body> </html> Firefox (3.6.3) will occasionally clear the value of the text box after hitting submit and then the back button. It's unpredictable when it will strike. And it will work for dozens to hundreds of times, and then all of a sudden it stops working. Any ideas where I should start?

  • Nesting arrays into NSDictionary object (Objective-C)

    - by antalbud
    I would like to define tasks using NSDictionary, which I'd like to save in a plist file (I didn't have much luck with Core Data so far), but got stuck at two points: -- When using initWithObjectsAndKeys: I can change the data type to number or boolean, using NSDate's numberWithInt: and numberWithBool: methods, respectively. I can't seem to find the method to change the type to date though. I couldn't find anything like that in the documentation. -- The second problem I ran into was with the nested arrays. How can I add them to the dictionary? I have uploaded a picture to here of what I am trying to achieve. Thank you in advance!

  • Rails gives wrong headers after upgrade 2.3.5 -> 2.3.8

    - by macsniper
    I just upgraded from rails 2.3.5 to rails 2.3.8, but now my redirects are not working properly. I get the following as the response HTTP Headers: HTTP/1.1 302 Moved Temporarily Date: Wed, 02 Jun 2010 09:40:39 GMT Content-Length: 93 Content-Type: text/html whereas I got previous: HTTP/1.1 302 Moved Temporarily Connection: close Date: Wed, 02 Jun 2010 09:41:18 GMT Set-Cookie: _session_id=<correct id>; path=/ Status: 302 Found Location: <correct url> Cache-Control: no-cache Server: Mongrel 1.1.5 Content-Type: text/html; charset=utf-8 Content-Length: 93 Anyone knows how to fix this? Despite the fact that the redirect is not working, the login-cookie is not set too (but I think, this is both related somehow). I have already tried to override redirect_to in order to set response.headers['Location'] etc., but they did not appear in the response.

  • Why do we need Web-Api? [closed]

    - by user437973
    I was just wondering what the deal is with Asp.net Web-Api. Why did we need a separate type of controller in order to facilitate varying content types for action results? Why wasn't this capability just baked into the ASP.Net MVC base controller? Anyway, I was just wondering if there was a compelling reason to use both types of controllers within the same project, assuming that the project was being freshly created, or if this project structure was due to an inherent technical limitation. Would it be possible to have ApiControllers fulfill the purpose of an MVC Controller in all cases by just serving HTML when that is the specified accept type? It just seems to me like a lot of unnecessary repetition to have to re-implement the same types of actions using both types of controllers if you want those actions to be available to your web application through the API and through the web interface.

  • Generic Dictionary - Getting Conversion Error

    - by pm_2
    The following code is giving me an error: // GetDirectoryList() returns Dictionary<string, DirectoryInfo> Dictionary<string, DirectoryInfo> myDirectoryList = GetDirectoryList(); // The following line gives a compile error foreach (Dictionary<string, DirectoryInfo> eachItem in myDirectoryList) The error it gives is as follows: Cannot convert type 'System.Collections.Generic.KeyValuePair<string,System.IO.DirectoryInfo>' to 'System.Collections.Generic.Dictionary<string,System.IO.DirectoryInfo>’ My question is: why is it trying to perform this conversion? Can I not use a foreach loop on this type of object?

  • Should I use ObservableCollections in my Model in M-V-VM

    - by Bill Jeeves
    I'm completely new to M-V-VM and very new to Silverlight, just reading about it for the first time today. As a sample, I am creating a model containing a list of items. My (Silverlight 4) View contains a listbox and my ViewModel will look to the model to retrieve the collection that the listbox will bind to. My question is this. I think it would be good to use an ObservableCollection to hold the items that the listbox binds to. This would be an ObseravleCollection in the ViewModel. Should I also use this type of collection in the model, or should I use another collection type and do smoe conversion between model and viewmodel?

  • Wherewith replace Dictionary.Where(p => p.Key is T)

    - by abatishchev
    I have a System.Collections.Generic.Dictionary<System.Web.UI.Control, object> where all keys can be either type of System.Web.UI.WebControls.HyperLink or type of System.Web.UI.WebControls.Label. I want to change Text property of each control. Because HyperLink doesn't implement (why??) ITextControl, I need to cast Label or HyperLink explicitly: Dictionary<Control,object> dic = .. dic .Where(p => p.Key is HyperLink) .ForEach(c => ((HyperLink)c).Text = "something") dic .Where(p => p.Key is Label) .ForEach(c => ((Label)c).Text = "something") Are there ways to workaround such approach?

  • move text from one div to another with javascript or mootools

    - by Ke
    Hi, I have two divs. I would like to move/populate the text from div id one to div id two using an onclick event. I am wondering how to do this? and also whether mootools can be used to accomplish the task or whether simple javascript is only necessary? <div id='one'> <ul> <input type="checkbox" onclick = "my_function()"/> <li>some text 1</li> <input type="checkbox" onclick = "my_function()"/> <li>some text 2</li> </ul> <div> <div id='two'> <div> Cheers in advance for any helps. Bangin my head against a brick wall here, because my javascript skillz are limited! Ke

  • F# equivalent of the C# typeof(IEnumerable<>)

    - by Rune FS
    I have a piece of code where I need to figure out if a given type implements IEnumerable (I don't care about the T) I've tried (t:System.Type in case you wonder) let interfaces = t.GetInterfaces() let enumerbale = interfaces.Any( fun t -> (t.GetGenericTypeDefinition() = typeof<IEnumerable<>>) however that wont compile (the compile don't like the <). I then tried let interfaces = t.GetInterfaces() let enumerbale = interfaces.Any( fun t -> (t.GetGenericTypeDefinition() = typeof<IEnumerable<'a>>) but get's a warning that 'a is constraint to obj. I Don't want to figure out if IEnumerable is implemented but IEnumerabl<. Any one know's the solution and btw feel free to comment on the code above as well. It's my first non-trivial F# program

  • WPF: Set style on immediate children only

    - by ollifant
    In my application I have a tab control which has several tab items. The problem is that I want to apply a style to these tab items, but to no other (nested) tab items. I have tried setting the following style on the tab control, but this also effects all children: <Style x:Key="tabControlStyle" TargetType="{x:Type TabControl}"> <Setter Property="TabItem.Template" Value="{StaticResource tabItemTemplate}" /> </Style> By using the code above I get the following error: 'TabItem' ControlTemplate TargetType does not match templated type 'TabControl', as TabItem and TabControl have the same DependencyProperty "Template", and the code tries to set the TabItemTemplate as TabControl- Template. Can anybody help me?

  • Problem in populating a dictionary object using Enumerable.Range() (C#3.0)

    - by Newbie
    If I do for (int i = 0; i < appSettings.Count; i++) { string key = appSettings.Keys[i]; euFileDictionary.Add(key, appSettings[i]); } It is working fine. When I am trying the same thing using Enumerable.Range(0, appSettings.Count).Select(i => { string Key = appSettings.Keys[i]; string Value = appSettings[i]; euFileDictionary.Add(Key, Value); }).ToDictionary<string,string>(); I am getting a compile time error The type arguments for method 'System.Linq.Enumerable.Select(System.Collections.Generic.IEnumerable, System.Func)' cannot be inferred from the usage. Try specifying the type arguments explicitly. Any idea? Using C#3.0 Thanks
