  • Click event keeps firing

    - by Ben Shelock
    I have absolutely no idea why this is happening but the following code seems to be executed a huge ammount of times in all browsers. $('#save_albums').click(function(){ for(var i = 1; i <= 5; i++){ html = $('#your_albums ol li').eq(i).html(); alert(html); } }); Looks fairly innocent to me... Here's the code in it's entirety $(function(){ $('#query').keyup(function(){ var text = encodeURI($(this).val()); if(text.length > 3){ $('#results').load('search.php?album='+text, function(){ $('.album').hover(function(){ $(this).css('outline', '1px solid black') },function(){ $(this).css('outline', 'none') }); $('.album').click(function(){ $('#fores').remove(); $('#yours').show(); if($('#your_albums ol li').length <= 4){ albumInfo = '<li><div class="album">' + $(this).html() + '</div></li>'; if($('#your_albums ol li').length >= 1){ $('#your_albums ol li').last().after(albumInfo); } else{ $('#your_albums ol').html(albumInfo); } } else{ alert('No more than 5 please'); } }); $('#clear_albums').click(function(e){ e.preventDefault; $('#your_albums ol li').remove(); }); $('#save_albums').click(function(){ for(var i = 1; i <= 5; i++){ html = $('#your_albums ol li').eq(i).html(); alert(html); } }); }); } else{ $('#results').text('Query must be more than 3 characters'); } }); });

  • Why is PHP not allowing comparison?

    - by dcp3450
    I'm using PHP to read if an entry in my table on the database is set to "yes" or "no" and auto check the radio button that corresponds: <?php include 'file.php'; $query = "SELECT * FROM TABLE"; $runquery = odbc_exec($connect,$query); $status= odbc_result($runquery,"status"); odbc_close($file); ?> <form> <div class="formContainer"> <fieldset> <legend>Campus Alert<span class="tooltip">Turn campus alert on and off.</span></legend> <?php echo $status; ?> Yes <input type="radio" name="alertStatus" id="alertStatus" value="yes" <?php if($status== "yes") echo "checked";?>> No <input type="radio" name="alertStatus" id="alertStatus" value="no" <?php if($status== "no") echo "checked";?>> </fieldset> </div> the is for debugging so I can make sure what the database says and the form's reaction is correct. It prints "yes" (no quotes). However, the if statement will not respond. Any idea why it's doing this?

  • HTML - Correct way of coding a checkbox with a Label.

    - by egarcia
    I've been using formtastic in order to generate HTML forms on rails applications. My question, however, is really HTML-related. Today I found a strange behaviour on the way formtastic generates checkboxes (fields of type :boolean on formtastic lingo). The rest of the fields (non-checkboxes) are generated this way: <li> <label for="my_textbox_field">My TextBox</label> <input id="my_textbox_field" type="text" ... > </li> Checkboxes, however, are enclosed inside their <label> tags completely - like this: <li> <label for="my_boolean_field"> <input id="my_boolean_field" type="checkbox" ... > This is my boolean field </label> </li> Formtastic phylosophy seems to be based on the Learning to Love Forms presentation. In effect, on slide 36 of that presentation this structure is suggested for checkboxes. I guess in the presentation itself the presenter explained why this was done, but it is not written on the slides. Can anyone tell me why enclosing checkboxes inside their <label> tag might be a good idea, as opposed to putting them outside, like with textboxes?

  • HTTP Basic authentication using Authlogic or authenticate_or_request_with_http_basic for API call?

    - by Gaius Parx
    I have a Rails 2.3.x app that implements the act_as_authentic in User model and a UserSession model as per Authlogic Github example. I am implementing an API to allow access from iPhone. Will be using HTTP Basic authentication via https (will not implement single access token). Each API call requires a username/password for the access. I am able to access the API by calling http://username:password@localhost:3000/books.xml for example. Authlogic will not persist if using the single access token. But I am using HTTP Basic which I think Authlogic will create session for the API calls, which is not used for my API methods. So for each API call I made, new session object is created. Thus appear to me that this would load up the server resource pretty quickly. Sounds like a bad idea. The alternative is to use the Rails authenticate_or_request_with_http_basic for API controllers. Example adding a before_filter: def require_http_auth_user authenticate_or_request_with_http_basic do |username, password| if @current_user = User.find_by_email(username) @current_user.valid_password?(password) else false end end end This will bypass the Authlogic UserSession and just use the User model. But this will involve using separate authentication codes in the app. Anyone has any comments and can share their experience? Thanks

  • How to implement two way binding between an ActiveX control and a WPF MVVM View Model

    - by Zamboni
    I have a WPF application implemented using the MVVM framework that uses an ActiveX control and I need to keep the WPF and ActiveX UI synchronised. So far I can update the ActiveX UI when I change the WPF UI using the code at the bottom of the question that I got from the article Hosting an ActiveX Control in WPF and this question. But I cannot update the WPF UI when I make a change in the ActiveX UI. I suspect that I need to fire the PropertyChanged event from my ActiveX control but I have no idea how to do this or if it is even possible. The ActiveX controls I have written are in VB6 and MFC as I am just prototying at this time for the eventual integration of VB6 ActiveX controls in a WPF contaner application. Here is a code snipet that indicates the work done so far: System.Windows.Forms.Integration.WindowsFormsHost host = new System.Windows.Forms.Integration.WindowsFormsHost(); // Create the ActiveX control. AxTEXTBOXActiveXLib.AxTEXTBOXActiveX axWmp = new AxTEXTBOXActiveXLib.AxTEXTBOXActiveX(); // Assign the ActiveX control as the host control's child. host.Child = axWmp; axWmp.DataBindings.Add(new System.Windows.Forms.Binding("ActiveXStatus", (MainWindowViewModel)this.DataContext, "ModelStatus", true, DataSourceUpdateMode.OnPropertyChanged )); // Add the interop host control to the Grid // control's collection of child controls. this.activexRow.Children.Add(host); How to implement two way binding between an ActiveX control and a WPF MVVM View Model?

  • Windows Programming: ID2D1Bitmap Interface - Getting the Bitmap Data

    - by LostInBrackets
    I've been writing my own library of functions to access some of the new Direct2D Windows libraries. In particular, I've been working on the ID2D1Bitmap interface. I wanted to write a function to return a pointer to the start of the bitmap data (for the editing of particular pixels, or custom encoding or whatever else I might wish for in the future). Unfortunately... problem ahead... I can't seem to find a way to get access to the raw pixel data from the ID2D1Bitmap Interface. Does anyone have an idea how to access this? One of my friends suggested drawing the bitmap to a surface and extracting the bitmap data from there. I don't know if this would work. It definitely seems inefficient and I wouldn't know which kind of surface to use. Any help is appreciated. (c++ in particular, but I assume the code won't be tooo different between languages) (I know I could just read in the data direct from the file, but I'm using the WIC decoders which means it could be in any number of indecipherable formats)

  • WPF Grid Row / Column Sizing in Proportion to DesiredSize?

    - by sinibar
    I have two user controls arranged vertically in a grid, both of which can expand to be taller than the grid can accommodate. I've put them in each in a scrollviewer which functionally works. What I want though is to give them them space in proportion to the amount that they want at run time. So if there's 500 height available, the upper control wants 400 and the lower 600, the upper control would get 200 and the bottom 300. I have no idea at design time how much space each will want in proportion to the other, so using 1*, 2* etc. for row height won't work for me. I can hand-code run-time proportional sizing, but am I missing a simple trick in XAML that would get me what I want? Context is as follows (trimmed for brevity)... <Grid> <TabControl> <TabItem> <Grid> <Grid> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition Height="*"/> <RowDefinition Height="*"/> </Grid.RowDefinitions> <GroupBox Grid.Row="0" Header="Title Area" /> <ScrollViewer Grid.Row="1" VerticalScrollBarVisibility="Auto"> <UserControl /> </ScrollViewer> <ScrollViewer Grid.Row="2" VerticalScrollBarVisibility="Auto"> <UserControl /> </ScrollViewer> </Grid> </Grid> </TabItem> </TabControl> </Grid>

  • Treebeard admin in Django

    - by Sharath
    I've setup Treebeard in Django and everything seems to have gone well. I tried to setup the admin system and I can see my models being presented in the admin interface. However, when I try to add new data using the admin interface, I get the following error in my template. The code still works fine, and I did a check in my DB and the data seems to be inserted properly. However, the view doesn't seem to load properly. Any idea about what is causing this??

  • Java: How do you really force a GC using JVMTI's ForceGargabeCollection?

    - by WizardOfOdds
    I'm not looking for the usual "you can only hint the GC in Java using System.gc()" answers, this is not at all what this question is about. My questions is not subjective and is based on a reality: GC can be forced in Java for a fact. A lot of programs that we use daily do it: IntelliJ IDEA, NetBeans, VisualVM. They all can force GC to happen. How is it done? I take it they're all using JVMTI and more specifically the ForceGarbabeCollection (notice the "Force") but how can I try it for myself? http://java.sun.com/javase/6/docs/platform/jvmti/jvmti.html#ForceGarbageCollection Also note that this question is not about "why" I'd want to do this: the "why" may be "curiosity" or "we're writing a program similar to VisualVM", etc. The question is really "how do you force a GC using JVMTI's ForceGarbageCollection"? Does the JVM needs to be launched with any special parameters? Is any JNI required? If so, what code exactly? Does it only work on Sun VMs? Any complete and compilable example would be most welcome.

  • Where should 'CreateMap' statements go?

    - by jonathanconway
    I frequently use AutoMapper to map Model (Domain) objects to ViewModel objects, which are then consumed by my Views, in a Model/View/View-Model pattern. This involves many 'Mapper.CreateMap' statements, which all must be executed, but must only be executed once in the lifecycle of the application. Technically, then, I should keep them all in a static method somewhere, which gets called from my Application_Start() method (this is an ASP.NET MVC application). However, it seems wrong to group a lot of different mapping concerns together in one central location. Especially when mapping code gets complex and involves formatting and other logic. Is there a better way to organize the mapping code so that it's kept close to the ViewModel that it concerns? (I came up with one idea - having a 'CreateMappings' method on each ViewModel, and in the BaseViewModel, calling this method on instantiation. However, since the method should only be called once in the application lifecycle, it needs some additional logic to cache a list of ViewModel types for which the CreateMappings method has been called, and then only call it when necessary, for ViewModels that aren't in that list.)

  • Combine Text with a Draggable Mask AS3.0

    - by RC
    So I have an image that is the size of the stage: img_mc. Then I drew a small rectangle: mask_mc. The idea is to make a "window" of the small rectangle, view img_mc through the window, and be able to drag the window around. The following code works fine but I want to add text to the mask - "Drag Me!" or whatever. But if I group text with the mask it breaks down. If I make a separate text_mc I can drag it around but it's not part of the mask. How can I combine text with a mask? (sorry if this question is pathetically easy!) Thanks for any thoughts you can share! img_mc.mask = mask_mc; mask_mc.buttonMode = true; img_mc.cacheAsBitmap = true; //because I blurred the mask text_mc.addEventListener(MouseEvent.MOUSE_DOWN, dragF); mask_mc.addEventListener(MouseEvent.MOUSE_DOWN, dragF); stage.addEventListener(MouseEvent.MOUSE_UP, dropF); function dragF(event:MouseEvent):void{ mask_mc.startDrag(); } function dropF(event:MouseEvent):void{ mask_mc.stopDrag(); }

  • glitchy stuttery iphone game loop

    - by Adam
    This is a problem I've been trying to solve for a few days now, and I've looked at the various solutions on stackoverflow and nothing has really seemed to work for me. I'm making an iPhone game with OpenGLES graphics and accelerometer input, at this point it's very simple, but the rendering is already pretty bad... it stutters and seems to jump back or forward in time. It doesn't happen a lot, but it happens enough to be a problem. I mean, who wants to play a game where a bullet gets magically transported into the player, and then it's game over? No one. I've tried using NSTimer for the game loop, I've tried using a separate thread (with a frame rate and continuously) I've tried using different frame rates, from 30FPS to 60FPS (It seems to have a max frame rate around 45FPS, but no problems at 30FPS) I've tried using timeIntervalSince1970 and CFGetAbsoluteTime to measure loop time, with no noticeable diffence Anyone have any ideas on what is the best way to get this looking better? One of the posts I've read suggested running the simulation at a fixed frame rate and then just render as fast as possible, does that seem like a good idea?

  • ASP.NET MVC Image refreshing

    - by user295541
    Hi, I have an Employee object which has an image property. Image class contains image metadata as image caption, and image file name. If I upload a new image for an employee on async way without full post back the new image is not appeared on the page. I use GUID to name the image file to avoid the page caching. I do the image modifying the following way: ctrEmployee employee = Repository.Get(PassedItemID); if (employee.ctrImage != null) { string fullFileName = serverFolder + employee.ctrImage.FileName; FileInfo TheFile = new FileInfo(fullFileName); if (TheFile.Exists) { TheFile.Delete(); } fileName = Guid.NewGuid() + ".jpg"; employee.ctrImage.FileName = fileName; } resizedBmp.Save(string.Format("{0}{1}", serverFolder, fileName), System.Drawing.Imaging.ImageFormat.Jpeg); Repository.Edit<ctrEmployee>(employee); ImageID = employee.Image.Value; return PartialView(UserControlPaths.Thumbnail, new ThumbnailDataModel(employee.Image.Value, 150, 150)); The partial view has an image tag which gets the saved image url string which is a GUID. Anybody has an idea what I do wrong?

  • How to detect hidden field tampering?

    - by Myron
    On a form of my web app, I've got a hidden field that I need to protect from tampering for security reasons. I'm trying to come up with a solution whereby I can detect if the value of the hidden field has been changed, and react appropriately (i.e. with a generic "Something went wrong, please try again" error message). The solution should be secure enough that brute force attacks are infeasible. I've got a basic solution that I think will work, but I'm not security expert and I may be totally missing something here. My idea is to render two hidden inputs: one named "important_value", containing the value I need to protect, and one named "important_value_hash" containing the SHA hash of the important value concatenated with a constant long random string (i.e. the same string will be used every time). When the form is submitted, the server will re-compute the SHA hash, and compare against the submitted value of important_value_hash. If they are not the same, the important_value has been tampered with. I could also concatenate additional values with the SHA's input string (maybe the user's IP address?), but I don't know if that really gains me anything. Will this be secure? Anyone have any insight into how it might be broken, and what could/should be done to improve it? Thanks!

  • Are there more Cocoa and Cocoa Touch videos which are worth looking at?

    - by dontWatchMyProfile
    To gain a better understanding, I think it would be a good idea to watch every cocoa video available on the net. I tend to find session videos from conferences or good podcast videos only by accident, so maybe someone has a handy list of links to great ressources. I already know all the WWDC stuff and the stuff from stanford, but a lot of universities around the world publish session videos as well in local languages. Also, there are like thousands of conferences around the world with great session videos. This list should compensate for all those who can't afford beeing at WWDC. Therefore, guys, let's create a handy list to fill the gaps for everyone! This is community wiki, so just list them all! I'll start with: English 360 Conferences (360iDev) Videos Oredev with some good iPhone dev session videos German Macoun 2009 with some interesting session videos, if you can speak German Please don't hesitate to post links to videos in other languages than English. Many of us speak more languages, so go ahead! We'll be excited!

  • Getting error: "This webpage is not available" for my chrome app's options page

    - by Don Rhummy
    My CRX had the proper html page options.html in it, the manifest declares it properly (it shows up as a link on the chrome://extensions page) but when I click that link, Chrome gives the error: This webpage is not available The webpage at chrome-extension://invalid/ might be temporarily down or it may have moved permanently to a new web address. It says "invalid" but the app runs perfectly well (all the content scripts run, the background created a database and saved to it). Why would it show as invalid? Why doesn't it have the extensions' id? Here's the manifest: { "manifest_version": 2, "name": "MyAPP", "description": "My App", "version": "0.0.0.32", "minimum_chrome_version": "27", "offline_enabled": true, "options_page": "options.html", "icons": { "16": "images/icon16.png", "48": "images/icon48.png", "128": "images/icon128.png" }, "app": { "background": { "scripts": [ "scripts/background.js" ] } }, "permissions": [ "unlimitedStorage", "fullscreen", { "fileSystem": [ "write" ] }, "background", "<all_urls>", "tabs" ] } Does it need to be declared in "web_accessible_resources"? Any idea what's wrong? Update Adding to "web_accessible_resources" does not fix the issue. I added everything on that page too. update 2 It looks like it might be a Chrome bug for packaged apps. When I remove the "app" section in the manifest, it works! This is a bug since the Chrome app documentation states that apps can have options pages: https://developer.chrome.com/apps/options.html

  • Parsing large delimited files with dynamic number of columns

    - by annelie
    Hi, What would be the best approach to parse a delimited file when the columns are unknown before parsing the file? The file format is Rightmove v3 (.blm), the structure looks like this: #HEADER# Version : 3 EOF : '^' EOR : '~' #DEFINITION# AGENT_REF^ADDRESS_1^POSTCODE1^MEDIA_IMAGE_00~ // can be any number of columns #DATA# agent1^the address^the postcode^an image~ agent2^the address^the postcode^^~ // the records have to have the same number of columns as specified in the definition, however they can be empty etc #END# The files can potentially be very large, the example file I have is 40Mb but they could be several hundred megabytes. Below is the code I had started on before I realised the columns were dynamic, I'm opening a filestream as I read that was the best way to handle large files. I'm not sure my idea of putting every record in a list then processing is any good though, don't know if that will work with such large files. List<string> recordList = new List<string>(); try { using (FileStream fs = new FileStream(path, FileMode.Open, FileAccess.Read)) { StreamReader file = new StreamReader(fs); string line; while ((line = file.ReadLine()) != null) { string[] records = line.Split('~'); foreach (string item in records) { if (item != String.Empty) { recordList.Add(item); } } } } } catch (FileNotFoundException ex) { Console.WriteLine(ex.Message); } foreach (string r in recordList) { Property property = new Property(); string[] fields = r.Split('^'); // can't do this as I don't know which field is the post code property.PostCode = fields[2]; // etc propertyList.Add(property); } Any ideas of how to do this better? It's C# 3.0 and .Net 3.5 if that helps. Thanks, Annelie

    I wrote this little function for writing out HTML tags: def html_tag(tag, content=None, close=True, attrs={}): lst = ['<',tag] for key, val in attrs.iteritems(): lst.append(' %s="%s"' % (key, escape_html(val))) if close: if content is None: lst.append(' />') else: lst.extend(['>', content, '</', tag, '>']) else: lst.append('>') return mark_safe(''.join(lst)) Which worked great, but then I read this article on efficient string concatenation (I know it doesn't really matter for this, but I wanted consistency) and decided to update my script: def html_tag(tag, body=None, close=True, attrs={}): s = StringIO() s.write('<%s'%tag) for key, val in attrs.iteritems(): s.write(' %s="%s"' % (key, escape_html(val))) if close: if body is None: s.write(' />') else: s.write('>%s</%s>' % (body, tag)) else: s.write('>') return mark_safe(s.getvalue()) But now my HTML get escaped when I try to render it from my template. Everything else is exactly the same. It works properly if I replace the last line with return mark_safe(unicode(s.getvalue())). I checked the return type of s.getvalue(). It should be a str, just like the first function, so why is this failing?? Also fails with SafeString(s.getvalue()) but succeeds with SafeUnicode(s.getvalue()). I'd also like to point out that I used return mark_safe(s.getvalue()) in a different function with no odd behavior. The "call stack" looks like this: class Input(Widget): def render(self): return html_tag('input', attrs={'type':self.itype, 'id':self.id, 'name':self.name, 'value':self.value, 'class':self.itype}) class Field: def __unicode__(self): return mark_safe(self.widget.render()) And then {{myfield}} is in the template. So it does get mark_safed'd twice, which I thought might have been the problem, but I tried removing that too..... I really have no idea what's causing this, but it's not too hard to work around, so I guess I won't fret about it.

  • REST application, Transactions, Cache drop

    - by Julian Davchev
    Hi, I am building REST API in php with memcache layer on top for caching all resources. After some reading experience it turns out it's best when documents are as simple as posible...mainly due to dropping cache sequences. So if there is 'building','room' entities for the 'room' document I would only place the id of the 'building' and not the whole data of it. Then on api client side I would merge data as needed. Problem becomes when I need to update/insert (most cases more than one table). I update one resource but on second update system fails or whatever and there becomes database inconsistancies. I see several solutions: 1. Implement rest transactions which I find wrong and complex as idea is to be stateless and easy. 2. On update/insert actions I pass more complex data (not single entities) so I can force transactions on API level. But this will make it weird that your GET document structure is same as PUT document structure. And again somehow make drop sequences complex. Any pointers are more than welcome. Cheers,

  • Changing FileNames using RegEx and Recursion

    - by yeahumok
    Hello I'm trying to rename files that my program lists as having "illegal characters" for a SharePoint file importation. The illegal characters I am referring to are: ~ # % & * {} / \ | : < ? - "" What i'm trying to do is recurse through the drive, gather up a list of filenames and then through Regular Expressions, pick out file names from a List and try to replace the invalid characters in the actual filenames themselves. Anybody have any idea how to do this? So far i have this: (please remember, i'm a complete n00b to this stuff) class Program { static void Main(string[] args) { string[] files = Directory.GetFiles(@"C:\Documents and Settings\bob.smith\Desktop\~Test Folder for [SharePoint] %testing", "*.*", SearchOption.AllDirectories); foreach (string file in files) { Console.Write(file + "\r\n"); } Console.WriteLine("Press any key to continue..."); Console.ReadKey(true); string pattern = " *[\\~#%&*{}/:<>?|\"-]+ *"; string replacement = " "; Regex regEx = new Regex(pattern); string[] fileDrive = Directory.GetFiles(@"C:\Documents and Settings\bob.smith\Desktop\~Test Folder for [SharePoint] %testing", "*.*", SearchOption.AllDirectories); StreamWriter sw = new StreamWriter(@"C:\Documents and Settings\bob.smith\Desktop\~Test Folder for [SharePoint] %testing\File_Renames.txt"); foreach(string fileNames in fileDrive) { string sanitized = regEx.Replace(fileNames, replacement); sw.Write(sanitized + "\r\n"); } sw.Close(); } } So what i need to figure out is how to recursively search for these invalid chars, replace them in the actual filename itself. Anybody have any ideas?

  • Binary file email attachment problem

    - by Alan Harris-Reid
    Hi there, Using Python 3.1.2 I am having a problem sending binary attachment files (jpeg, pdf, etc.) - MIMEText attachments work fine. The code in question is as follows... for file in self.attachments: part = MIMEBase('application', "octet-stream") part.set_payload(open(file,"rb").read()) encoders.encode_base64(part) part.add_header('Content-Disposition', 'attachment; filename="%s"' % file) msg.attach(part) # msg is an instance of MIMEMultipart() server = smtplib.SMTP(host, port) server.login(username, password) server.sendmail(from_addr, all_recipients, msg.as_string()) However, way down in the calling-stack (see traceback below), it looks as though msg.as_string() has received an attachment which creates a payload of 'bytes' type instead of string. Has anyone any idea what might be causing the problem? Any help would be appreciated. Alan builtins.TypeError: string payload expected: File "c:\Dev\CommonPY\Scripts\email_send.py", line 147, in send server.sendmail(self.from_addr, all_recipients, msg.as_string()) File "c:\Program Files\Python31\Lib\email\message.py", line 136, in as_string g.flatten(self, unixfrom=unixfrom) File "c:\Program Files\Python31\Lib\email\generator.py", line 76, in flatten self._write(msg) File "c:\Program Files\Python31\Lib\email\generator.py", line 101, in _write self._dispatch(msg) File "c:\Program Files\Python31\Lib\email\generator.py", line 127, in _dispatch meth(msg) File "c:\Program Files\Python31\Lib\email\generator.py", line 181, in _handle_multipart g.flatten(part, unixfrom=False) File "c:\Program Files\Python31\Lib\email\generator.py", line 76, in flatten self._write(msg) File "c:\Program Files\Python31\Lib\email\generator.py", line 101, in _write self._dispatch(msg) File "c:\Program Files\Python31\Lib\email\generator.py", line 127, in _dispatch meth(msg) File "c:\Program Files\Python31\Lib\email\generator.py", line 155, in _handle_text raise TypeError('string payload expected: %s' % type(payload))

  • ASP.Net MVC Json Result: Parameters passed to controller method issue

    - by Moskie
    I'm having a problem getting a controller method that returns a JsonResult to accept parameters passed via the JQuery getJSON method. The code I’m working on works fine when the second parameter ("data") of the getJSON method call is null. But when I attempt to pass in a value there, it seems as if the controller method never even gets called. In this example case, I just want to use an integer. The getJSON call that works fine looks like this: $.getJSON(”/News/ListNewsJson/”, null, ListNews_OnReturn); The controller method is like this: public JsonResult ListNewsJson(int? id) { … return Json(toReturn); } By putting a breakpoint in the ListNewsJson method, I see that this method gets called when the data parameter of getJSON is null, but when I replace it with value, such as, say, 3: $.getJSON(”/News/ListNewsJson/”, 3, ListNews_OnReturn); … the controller method/breakpoint is never hit. Any idea what I'm doing wrong? I should also mention that the controller method works fine if I manually go to the address via my browser ("/News/ListNewsJson/3").
