  • Is it necessary to memorize code?

    - by AAA
    I am a new developer, who just got hired at a big company. I don't know how but I guess they are desperate. However, I am well-versed with HTML5/CSS3 though things change and new things are released and I keep up with as much as I can. But this job required me to hand-code Javascript, know Jquery and Ajax. I have been exposed to this a bit but I am not sure if I can hand-code Javascript. My question is, is it necessary to memorize all there is about Javascript or are there a few key things that I should know how to hand-code because looking at javascript code it seems there are lots of lines code! Please point me in the right direction.

  • When going for an interview for web development at an agency, can a real example be expected?

    - by KPO
    I just started coding a year ago. By "coding" I mean HTML(5), CSS(3), and only a few times I implemented AJAX and JavaScript. I am interviewing for a position that expects me to know HTML, CSS, JS, JQuery, and AJAX. I am good with HTML5/CSS3 and somewhat ok with js. If I go for an interview, will they expect me to write code during the interview? I do have a live website as an example and snapshots of past projects that I sent to them. I am a little nervous, so any tips or something from your experience I can learn will be helpful.

  • How to delete row in TTTableViewController (Three20)

    - by Dmitry
    Hi, The Three20 is great library. It's making the work with tables very easy. But one gap that I noticed - is deletion of rows, with animation. I spent many hours trying to do this, and this is what I'm doing: // get current index patch UITableView* table = [super tableView]; NSIndexPath *indexPath = [table indexPathForSelectedRow]; //delete row in data source TTListDataSource * source = (TTListDataSource *)self.dataSource; [source.items removeObjectAtIndex:indexPath.row]; // delete row from the table, with animation [table deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; After this code runs the error appears: [NSCFArray objectAtIndex:]: index (0) beyond bounds (0) I'm using the class inherited from the TTTableViewController. And I doesn't implement the DataSourceDelegate or TableViewDelegate because I'm using the Three20 as much as possible. So, this is how I create datasource: for(NSDictionary *album in (NSArray *)albums){ TTTableRightImageItem *item = [TTTableRightImageItem itemWithText:@"name" imageURL:@"image url" defaultImage:nil imageStyle:TTSTYLE(rounded) URL:@"url of selector where I actually catch the tap on a row"]; [tableItems addObject:item]; } self.dataSource = [TTListDataSource dataSourceWithItems:tableItems]; I read this article (article) but it doesn't help :( So, I know that this is very simple for gurus from this site. Can you just give me advanced sample of how to do this Thanks

  • UISearchBar and UINavigationItem

    - by tbehunin
    I can't seem to get a UISearchBar to position itself from the far left to the far right in the navigation bar. In the -(void)viewDidLoad method, I have the following code: `UISearchBar *sb = [[UISearchBar alloc] initWithFrame:self.tableView.tableHeaderView.frame]; sb.delegate = self; self.navigationItem.titleView = sb; [sb sizeToFit]; [sb release];` When you build and run, it looks just fine at first glance. However, looking more closely, you can tell there is a margin/space on the left. This wouldn't be a big deal in the grand scheme of things, but when I tap the search bar to start a search, I animate the cancel button into view. Because the search bar is positioned slightly to the right, the animation is jerky and the cancel button falls off the end like so: link text It seems as if the UINavigationItem is like a table with three cells, where there is a padding on the first and last which I can't remove - nor does there seem to be a way to 'merge' it all together and then place the search bar there. I know this look is possible, because the AppStore search has a search bar in the navigation bar and it goes all the way to the edges. Anyone know how to get the search bar to go all the way to the edges so my slide-in cancel button animation will work properly?

  • Getting an Error Trying to Create an Object in Python

    I am trying to create an object from a class in python but I am getting an Error, "e_tank = EnemyTank() TypeError: 'Group' object is not callable" I am not sure what this means, I have tried Google but I couldn't get a clear answer on what is causing this error.

  • Ipad MPMovieplayerController video loads but automatically pauses when played

    Hello I am trying to get the MPMovieplayerController to work. I load a video everything goes wel i even see the first frame but then it automatically pauses, if i press play it pauses again. In the simulator it works perfectly but on the ipad device it gives the problem. I can even seek through the video and i see the frame i seeked to but nothing plays. This is some output from the console: 2010-06-08 22:16:13.145 app[3089:207] Using two-stage rotation animation.

  • CCSprite: setTexture doesn't work when the sprite is rendered using a CCSpriteSheet

    My code is in cocos2d. I am getting this error in my code. To get the fast animation I used CCSpriteSheet CCSpriteSheet *danceSheet = [CCSpriteSheet spriteSheetWithFile:@"new1.png"]; [self addChild:danceSheet]; CCSprite *danceSprite = [CCSprite spriteWithTexture:danceSheet.texture rect:CGRectMake(0, 0, 119, 320)]; [danceSheet addChild:danceSprite]; danceSprite.position = ccp(danceSprite.contentSize.width/2,danceSprite.contentSize.height/2); CCAnimation *danceAnimation = [CCAnimation animationWithName:@"dance" delay:0.1f]; int frameCount = 0; for (int x = 0; x < 13; x++) { // create an animation frame CCSpriteFrame *frame = [CCSpriteFrame frameWithTexture:danceSheet.texture rect:CGRectMake(x*119,0,119,320) offset:ccp(0,0)]; [danceAnimation addFrame:frame]; frameCount++; NSLog(@"frameCount value: %d", frameCount); if (frameCount == 13) break; } CCAnimate *danceAction = [CCAnimate actionWithAnimation:danceAnimation restoreOriginalFrame:NO ]; [danceSprite runAction:danceAction]; But when I touched the screen it is giving the error CCSprite: setTexture doesn't work when the sprite is rendered using a CCSpriteSheet

  • Can't write the SysWow64 value to registry with vbscript for Screensaver

    - by Valentein
    Scripts, registries, screen-savers, oh my! I'm trying to use a screen-saver on a Windows XP 64 bit machine which uses a .NET app which makes an interop call which relies on some x86 Shockwave Dlls (some Shockwave animation). Everything should be in the %systemroot%\WINNT\SysWOW64 directory. When the timeout for the screensaver occurs, the process should looks like this: Screensaver.scr - .NET app - shockwave animation. During installation I want a vbscript to my screen-saver file to copy the Screensaver.scr to the SysWow64 directory and then set the proper registry key to this file for Windows to launch the screen-saver. The code is something like this: Dim sScreenSaver, tScreenSaver sScreenSaver = "C:\SourceFiles\bin\ScreenSaver.scr" 'screensaver tScreenSaver = "C:\winnt\SysWOW64\" Set WshShell = WScript.CreateObject("WScript.Shell") 'script shell to run objects Set FSO = createobject("scripting.filesystemobject") 'file system object 'copy screensaver FSO.CopyFile sScreenSaver, tScreenSaver, True 'set screen saver Dim p1 p1 = "HKEY_CURRENT_USER\Control Panel\Desktop\" WshShell.RegWrite p1 & "SCRNSAVE.EXE", (tScreenSaver & "ScreenSaver.scr") After installation, I can verify the the Screensaver exists in the correct directory. (It actually seems to be in both the system32 and the sysWOW64 directories---whether that's the install script or something I did post-install I'm in the process of verifying.) However, the registry entry is not correct. In both the 32 and 64 bit regedit I see the HKCU\ControlPanel\Desktop\SCRNSAVE.EX is set to: C:\WINNT\system32\Screensaver.scr This isn't right. The screen-saver won't run from this directory. It only runs from SysWOW64. If I manually edit the registry with regedit to the correct SysWOW64 path everything works fine. Is this a problem with using the script or is this a Windows registry redirection, or filesystem redirection problem? You'd think this would be simple...

  • Making Firefox render canvas text the same as CSS text

    - by Dan Forys
    I've been experimenting with the canvas tag and Javascript. I've made a page that takes Tweets from the Twitter public timeline and animates them into view. It works by using a canvas element in the background for the animation. When the animation is complete, it creates a div element with the same text over the top. I do this so that the tweet text is selectable and links are clickable. Now, in Safari, Chrome and even Opera, the canvas text and div text look almost exactly the same. Yet in Firefox, the size of the text is different enough to make it 'jump' at the point it changes into the div. Does anyone know how to make Firefox render the text the same on the canvas element and the div using CSS? Or is this a rendering inconsistency with the engine. I have put the page on my website if you want to see what I mean. Now for the code: The CSS I'm using for rendering the div contains: line-height: 21px; font-weight: 100; font-family: Georgia, "New Century Schoolbook", "Nimbus Roman No9 L", serif; font-size: 20px; For rendering on the canvas I'm using: this.context.font = this.scale + 'px Georgia'; this.context.fillStyle = "white"; this.context.strokeStyle = 'white'; this.context.fillText(this.text, 0, 0); this.context.strokeText(this.text, 0, 0); where this.scale is an animated scale factor that finishes at 20px exactly. So, to recap, I'm using the same font and ending up at the same px size, yet Firefox renders the text differently between Canvas and CSS. (edit) Here's a screenshot example: First line is the text animating in using canvas, second line is the resulting div.

  • How can I handle events within my custom control?

    - by highone
    I am not looking to create new events. I need to create a canvas control that optionally fades in or out depending on whether or not the mouse is over it. The code below probably explains what I want to do better than I can. private Storyboard fadeInStoryboard; private Storyboard fadeOutStoryboard; public FadingOptionPanel() { InitializeComponent(); } public static readonly DependencyProperty FadeEnabledProperty = DependencyProperty.Register("IsFadeEnabled", typeof(bool), typeof(FadingOptionPanel), new FrameworkPropertyMetadata(true, OnFadeEnabledPropertyChanged, OnCoerceFadeEnabledProperty)); public bool IsFadeEnabled { get { return (bool)GetValue(FadeEnabledProperty); } set { SetValue(FadeEnabledProperty, value); } } private static void OnFadeEnabledPropertyChanged(DependencyObject source, DependencyPropertyChangedEventArgs e) { } private static object OnCoerceFadeEnabledProperty(DependencyObject sender, object data) { if (data.GetType() != typeof(bool)) { data = true; } return data; } private void FadingOptionPanel_MouseEnter(object sender, MouseEventArgs e) { if (IsFadeEnabled) { fadeInStoryboard.Begin(this); } } private void FadingOptionPanel_MouseLeave(object sender, MouseEventArgs e) { if (IsFadeEnabled) { fadeOutStoryboard.Begin(this); } } private void FadingOptionsPanel_Loaded(object sender, RoutedEventArgs e) { //Initialize Fade In Animation DoubleAnimation fadeInDoubleAnimation = new DoubleAnimation(); fadeInDoubleAnimation.From = 0; fadeInDoubleAnimation.To = 1; fadeInDoubleAnimation.Duration = new Duration(TimeSpan.FromSeconds(.5)); fadeInStoryboard = new Storyboard(); fadeInStoryboard.Children.Add(fadeInDoubleAnimation); Storyboard.SetTargetName(fadeInDoubleAnimation, this.Name); Storyboard.SetTargetProperty(fadeInDoubleAnimation, new PropertyPath(Canvas.OpacityProperty)); //Initialize Fade Out Animation DoubleAnimation fadeOutDoubleAnimation = new DoubleAnimation(); fadeOutDoubleAnimation.From = 1; fadeOutDoubleAnimation.To = 0; fadeOutDoubleAnimation.Duration = new Duration(TimeSpan.FromSeconds(.2)); fadeOutStoryboard = new Storyboard(); fadeOutStoryboard.Children.Add(fadeOutDoubleAnimation); Storyboard.SetTargetName(fadeOutDoubleAnimation, this.Name); Storyboard.SetTargetProperty(fadeOutDoubleAnimation, new PropertyPath(Canvas.OpacityProperty)); } I originally was using this code inside a usercontrol instead of a custom control before I found out that usercontrols don't support content.

  • jQuery and XHTML layout problems in ie7

    - by abysslogic
    Hi there, I am back again with more layout problems on my up and coming website. I am able to achieve the proper animation, positioning and results with my layout / splash on every modern browser (excluding ie7 or older). I have an image in the center of the page, that is text-align: center'd, and pushed to a vertical center by having a div (#SPLASH_HEAD) set to 50% on the top half of the page. The loading animation changes the height of #SPLASH_HEAD to 0px, to drag the image to the top (and then do other things). In ie7 (or compatability mode), it appears that there is an error in jquery-1.4.2.min.js, line 116 char 165 (which I dont think has anything to do with the actual jQuery file itself). The splash is not centered either vertically (#SPLASH_HEAD does not register at 50% of window height) and is not centered properly with margin-left. Also, none of the other elements are hidden properly (with .hide()) as ie7 does not appear to be loading all of my jQuery / javascript. heres a link: www.voidsync.com/test (it would be easier to view the source on there) thanks!

  • UINavigationController flashes white when I add it to a superview

    - by Chris Stamper
    Hey guys, I'm adding a NavigationController as a subview of my main view, with the flip animation (like a utility app/flipview thing). Here's how I'm doing it: [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:.7]; [UIView setAnimationTransition:([self.tableController.view superview] ? UIViewAnimationTransitionFlipFromLeft : UIViewAnimationTransitionFlipFromRight) forView:self.tableHostView cache:YES]; [self.tableController.view removeFromSuperview]; settingsView* backView1 = [[settingsView alloc] initWithNibName:@"settingsView" bundle:nil]; backView1.delegate = self; UINavigationController* settingsNavStack = [[UINavigationController alloc]initWithRootViewController:backView1]; [backView1 release]; settingsNavStack.view.frame = CGRectMake(0, 0, 320, 460); settingsNavStack.navigationItem.title = @"Settings"; [self setBackView:settingsNavStack]; [settingsNavStack release]; [self.tableHostView addSubview:self.backView.view]; [[self backView]setDelegate: self]; When it loads, the view comes in very nicely. However, the navigation bar stays white until like .2 secs after the animation finishes. Anyone know why the navigation bar wouldn't display right away?

  • Removing a view from it's superview causes memory error - why?

    - by mystify
    Xcode is throwing an error at me: malloc: * error for object 0x103f000: pointer being freed was not allocated * set a breakpoint in malloc_error_break to debug I tracked down the code until a line where I do this: - (void)inputValueCommitted:(NSString *)animationID finished:(BOOL)finished context:(void *)context { // retainCount of myView is 2! (one for the retain-property, one for beeing a subview) [self.myView removeFromSuperview]; // ERROR-LINE !! self.myView = nil; } When I remove that errorful line, the error is gone. So in conclusion: I can't get rid of my view! It's an UIImageView with nothing else inside, just showing an image. What I do is this: I create an UIView Animation Block, create that UIImageView, assign it to an retain-property with self.myView = ..., and after the animation is done, I just want to get rid of that view. So I remove it from it's superview and then set my property to nil, which lets it go away - in theory. Did anyone else encounter such issues? iPhone SDK 3.0.

  • How to detect when video is buffering?

    - by Leon
    Hi guys, my question today deals with Flash AS3 video buffering. (Streaming or Progressive) I want to be able to detect when the video is being buffered, so I can display some sort of animation letting the user know to wait just a little longer. Currently my video will start up, hold on frame 1 for 3-4 secs then play. Kinda giving the impression that the video is paused or broken :( Update Thanks to iandisme I believe I'm faced in the right direction now. NetStatusEvent from livedocs. It seems to me that the key status to be working in is "NetStream.Buffer.Empty" so I added some code in there to see if this would trigger my animation or a trace statement. No luck yet, however when the Buffer is full it will trigger my code :/ Maybe my video is always somewhere between Buffer.Empty and Buffer.Full that's why it won't trigger any code when I test case for Buffer.Empty? Current Code public function netStatusHandler(event:NetStatusEvent):void { // handles net status events switch (event.info.code) { case "NetStream.Buffer.Empty": trace("¤¤¤ Buffering!"); //<- never traces addChild(bufferLoop); //<- doesn't execute break; case "NetStream.Buffer.Full": trace("¤¤¤ FULL!"); //<- trace works here removeChild(bufferLoop); //<- so does any other code break; case "NetStream.Buffer.Flush": trace("¤¤¤ FLUSH!"); //Not sure if this is important break } }

  • WPF Trigger / Style overrides another

    - by ozczecho
    I have a listview defined as such <ListView Width="auto" SelectionMode="Single" ItemContainerStyle="{StaticResource baseListViewStyle}" .... Then in "baseListViewStyle" I have defined some base styles to apply to my list views, including a Style trigger: <Style x:Key="baseListViewStyle" TargetType="ListViewItem"> <Setter Property="Height" Value="20" /> <Setter Property="HorizontalContentAlignment" Value="Stretch"/> <Style.Triggers> <Trigger Property="IsMouseOver" Value="True"> <Setter Property="Foreground" Value="Red" /> </Trigger> </Style.Triggers> </Style> The trigger here highlights the row when mouse is over it. Nice. I also have a Data Trigger on the listviewitem: <Style.Triggers> <DataTrigger Binding="{Binding IsTestTrue}" Value="True"> <DataTrigger.EnterActions> <BeginStoryboard Storyboard="{StaticResource SomeFunkyAnimation}" /> </DataTrigger.EnterActions> </DataTrigger> If test is true then a nice little fade animation is played out. This all works except when I move my mouse over the row where "test is true" the animation stops and the mouse over style is displayed. Any ideas how I can override that style in my DataTrigger? TIA

  • Why does presentModalViewController not always work?

    - by E-Madd
    My application requires data from a server in order to run. The first thing it does is displays a view controller (LoadingViewController) that is responsible for checking if the data is saved to my PersistentStoreCoordinator. If the data isn't cached locally, it gets it from my server and caches it, and posts a notification that the LoadingViewController is listening for. When that notification comes through, LoadingViewController presents the application's MainViewController using the presentModalViewController with a flip animation. So far, so good... no errors. However, if the application loads and determines the data IS cached - the presentModalViewController does not work and the main application view never appears. No errors. I've even gone as far as adding a button to the Loading view that executes the same code when pressed and the damn thing works. I'm suspicious it has something to do with the timing of it all but I'm clueless as to what I can do to ensure the view is displayed with that flipping animation if the data is already cached locally. Any suggestions?

  • How to make a big switch control structure with variable check values?

    - by mystify
    For example, I have a huge switch control structure with a few hundred checks. They're an animation sequence, which is numbered from 0 to n. Someone said I can't use variables with switch. What I need is something like: NSInteger step = 0; NSInteger i = 0; switch (step) { case i++: // do stuff break; case i++: // do stuff break; case i++: // do stuff break; case i++: // do stuff break; } The point of this is, that the animation system calls a method with this big switch structure, giving it a step number. I want to be able to simply cut-copy-paste large blocks and put them in a different position inside the switch. for example, the first 50 blocks to the end. I could do that easily with a huge if-else structure, but it would look ugly and something tells me switch is much faster. How to?

  • Jquery animate bottom problem

    - by andrea
    It's strange. I have an animation that start when i .hover on a DIV. Into this div i have another in position absolute that i want to move up until the mouse stay on main div and go down in your position when i go out of main div. A simple hover effect. I have write down this function that work well apart a strange bug. var inside = $('.inside') inside.hover(function() { $(this).children(".coll_base").stop().animate({ bottom:'+=30px' },"slow") }, function() { $(this).children(".coll_base").stop().animate({ bottom:'-=30px' },"slow"); }); i need +=30 and -=30 because i have to apply this function to a range of div with different bottom. The problem is that if i hover on and out of div the DIV animate right but when go down he decrease the value of bottom every animation. If i go up and down from the main div i see that the animated div go down even beyond the main div. I think that i miss something to resolve this bug. Thanks for any help

  • Jquery - binding click event to a variable

    - by Kayote
    All, I am really stuck/ confused at this point. I have an array with 6 items in it. Each item in the array is dynamically filled with elements using jquery '.html' method. However, I cannot seem to be able to attach/ bind an event to this dynamically created variable. As soon as the browser gets to the problem line (see the area labeled 'PROBLEM AREA'), I get a 'undefined' error, which is really confusing as all the previous code on the very same variable works just fine. var eCreditSystem = document.getElementById("creditSystem"); var i = 0; var eCreditT = new Array(6); // 6 members created which will be recycled function createCreditTransaction () // func called when a transaction occurs, at the mo, attached to onclick() { if (i < 6) { eCreditT[i] = undefined; // to delete the existing data in the index of array addElements (i); } else if (i > 5 || eCreditT[i] != undefined) { ... } } function addElements (arrayIndex) // func called from within the 'createCreditTransaction()' func { eCreditT[i] = $(document.createElement('div')).addClass("cCreditTransaction").appendTo(eCreditSystem); $(eCreditT[i]).attr ('id', ('trans' + i)); $(eCreditT[i]).html ('<div class="cCreditContainer"><span class="cCreditsNo">-50</span>&nbsp;<img class="cCurrency" src="" alt="" /></div><span class="cCloseMsg">Click box to close.</span><div class="dots"></div><div class="dots"></div><div class="dots"></div>'); creditTransactionSlideOut (eCreditT[i], 666); // calling slideOut animation console.log(eCreditT[i]); // this confirms that the variable is not undefined /* ***** THE PROBLEM AREA ***** */ $(eCreditT[i]).on ('click', function () // if user clicks on the transaction box { creditTransactionSlideBackIn (eCreditT[i], 150); // slide back in animation }); return i++; }

Here's the gist of what the update looks like: $('#private-photo div').fadeOut(function() { $(this).html('<%= escape_javascript(image_tag current_user.private_photo.image.url(:profile)) %>'); }).fadeIn(); Basically it's just fading out the old content and fading in the new content. My problem is that when this happens, the browser window automatically scrolls up just far enough so that the bottom of the updated content (#private-photo div) appears at the top of the browser viewport. I do not want this to happen. I want the content to be updated (still fading in and out), but without the browser viewport realigning its focus. I want to keep the animation because if the user has a big enough screen, or if they are using a link closer to the top of the page, I still want them to see the animation. Any ideas about how to prevent the browser from scrolling as described? If not, any suggestions for workarounds? FYI, I have this same problem in Safari 4, Chrome (for Mac), & Firefox 3.5. EDIT: Here's the link that calls the update action, which is itself inside a Colorbox: $('a.edit-photo').colorbox({ title: function() { return 'Edit Photo in ' + $(this).attr('rel'); }, overlayClose: false, onComplete: function() { $('#edit-photo-modal').submit(function(e) { $('#photo_submit').after('<span id="saving">Saving...</span>'); e.preventDefault(); $.post($(this).attr('action'), $(this).serialize(), function() { $('#edit-photo-modal #saving').text('Saved!'); }, "script"); }); } }); The lightbox opens, presents a form fetched through an AJAX request, then (on submit) triggers the update action mentioned above. I had these links outside of the Colorbox in an earlier design revision, and they exhibited the same problem, so I've ruled out Colorbox itself as a cause. If you need anymore info, let me know!

  • CSS3 transition on table row using height property

    - by Alexis Leclerc
    I have an HTML table displaying some information with a few rows. On each row, the user can click to reveal some additional rows that contains information related to the clicked row. Something like this: While the additional rows are being created with an AJAX request, a loading row is inserted right after the clicked row : Currently, everything works perfectly (drill down style), but I would like to add some animation to the loading row. I found a question ( this one ) that has a JSFiddle showing kind of what I want ( this fiddle ). I tried to implement something similar with CSS3 transitions, but I can't get it to work. Here's my simulated attempt ( fiddle only for deployment of the loading row ) using these transitions : -webkit-transition: height 0.1s ease-in-out; -moz-transition: height 0.1s ease-in-out; -ms-transition: height 0.1s ease-in-out; -o-transition: height 0.1s ease-in-out; transition: height 0.1s ease-in-out; Any thought on why my fiddle doesn't do any animation? Any other methods you would propose? Thanks!
