  • jQuery child of clicked element

    - by Tom
    Hi, I've got a list of links which have a click event attached to them, I need to get the ID from the child A link. So in the example below if I clicked the first list element I'd need google retuned. I've tried '$this a' but can't quite work out the syntax. jQuery: $("ul li").click(function(event){ $("input").val($(this).html()); } ); html: <ul> <li><a href="http://www.google.com" id="google">Google</a> </ul>

  • Soundboard app: Play sound as long as the user is pressing the button

    - by Pantelis Proios
    I am making a soundboard app and i am using sounds with over 30sec duration. I am playing the sound by connecting in IB my action with a "touch down" event, however the sound keeps playing once started. I connected in the some button a "touch cancel" & "touch up outside" event that is supposed to stop the sound but for some reason it doesn't. Can anybody provide a solution to my problem? ---Edit--- Here is my code: -(IBAction)playSound:(id)sender { NSString *soundFile; soundFile = [[NSBundle mainBundle] pathForResource:@"testSound" ofType:@"mp3"]; audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:soundFile] error:nil]; audioPlayer.volume = volumeSlider.value; audioPlayer.numberOfLoops = -1; [audioPlayer prepareToPlay]; [audioPlayer play]; } -(IBAction)stopSound:(id)sender { [audioPlayer stop]; }

  • jQuery Week Calendar overlapping problem

    - by araid
    Hi, I'm developing an application with uses this calendar for resource reservation, but I have a problem when creating a new event. I don't want events to overlap, so I set allow allowCalEventOverlap to false. However, it still overlaps in a transparent way. But the biggest problem is that I can't drag an event if there's another on the same day, even if their start and end dates don't overlap. You can try this strange behavior in the 2nd demo: http://robmonie.github.com/jquery-week-calendar/weekcalendar_demo_2.html Any help on how to fix or understand it will be very appreciated. Regards,

  • Jquery Scrolling

    - by Rich - Pixel Vector
    I have implemented the following code from this page: http://tympanus.net/codrops/2010/06/02/smooth-vertical-or-horizontal-page-scrolling-with-jquery/ $(document).ready(function() { $('ul.navone li a, ul.navtwo li a,a.toplink, a.bodylink').bind('click',function(event){ var $anchor = $(this); $('html, body, header').stop().animate({ scrollTop: $($anchor.attr('href')).offset().top }, 1500,'easeInOutExpo'); event.preventDefault(); }); }); This all works correctly. However, in my layout I have a fixed header div (i.e. it stays in place when the user scrolls). Therefore I need to set an offset for the scrolling script of 117 pixels. How do I do this please?

  • Behaviour of System.Timer when Interval property changed

    - by lowlyintern
    I have a System.Timer setup to trigger an event every day at 2AM. If the process the timer starts fails then I want the timer to be reset to run every 15 minutes until the process completes succesfully. // this is how the timer is set up. // this is working correctly. double startTime = milliseconds_of_hour_to_start. Timer = new System.Timers.Timer( startTime); Here is the code to reset the timer on success or failure of the event handler. NOTE the timer is not being stopped, just the Interval property is being reset. if (ProcessSuccess) { Timer.Interval = TimeSpan.FromHours(24).TotalMilliseconds; } else { Timer.Interval = TimeSpan.FromMinutes(15).TotalMilliseconds; } My question is this, if the process fails say 4 times, then succeeds will the Timer now be running at around 3AM? i.e. after failing will the original start time of 2AM be advanced by 15 minutes?

  • Attach an HREF and a class to an img link generated by the PhotoSlider script?

    - by Frank Bailey
    Hi folks, I'm using the very nice PhotoSlider script from http://opiefoto.com/articles/photoslider to create a slide show of images for one of my clients. This script replaces a previous hand-coded Javascript solution that allowed for the large image to be clicked resulting in a lightbox modal popup showing the full-size version of the clicked picture. Of course the client insists that this functionality remain intact, but the HTML code for the large image is generated on-the-fly by the PhotoSlider script itself. This means I'll need to modify the script slightly to attach a class ("lightbox") and an href (or just a click event, whichever makes more sense), but I'm not quite sure how best to accomplish this. I figure the event and class will have to be attached each time a thumbnail is clicked, but if this isn't the best way to do it any advice will be appreciated. The script is implemented into my page as can be seen here, without the click or class. I'd really appreciate any assistance stackoverflowites can offer. Thanks in advance!

  • Possible to implement an IsViewPortVisible dependencyproperty for an item in an ItemsControl?

    - by Matt H.
    I need to enable/disable spell checking in a richtextbox in an ItemsControl, based on whether the RichTextBox is visible in the ItemsControl's Scrollviewer. I think the route is to implement an IsViewPortVisible dependency property and wire an event handler for a changed event... I found this article that describes the lengthy process for determining if an item is in the viewport: http://social.msdn.microsoft.com/Forums/en/wpf/thread/e6ccfec3-3dc0-4702-9d0d-1cfa55ecfc90 Any ideas on where to start? I'm familiar with implementing my own dependency property for the sake of simple bindings (integers, strings, etc...). I have no idea how to undergo something like this though) This is the end result I'm hoping for: <DataTemplate> <Grid> ...Stuff in the Grid <local:CustomRichTextBox SpellCheck.IsEnabled={Binding RelativeSource={RelativeSource Self}, Path=IsViewPortVisible}/> </Grid> </DataTemplate> Help will be EXTREMELY appreciated... you'll be saving me about 500MB in memory consumption while the program is running!!!! :)

  • Adding Timestamp to Java's GC messages in Tomcat 6

    - by ripper234
    I turned on Java's GC log options -XX:+PrintGC -XX:+PrintGCTimeStamps -XX:+PrintGCDetails Which print out these messages to standard output (catalina.out): 314.884: [CMS-concurrent-mark-start] 315.014: [CMS-concurrent-mark: 0.129/0.129 secs] [Times: user=0.14 sys=0.00, real=0.13 secs] 315.014: [CMS-concurrent-preclean-start] 315.016: [CMS-concurrent-preclean: 0.003/0.003 secs] [Times: user=0.00 sys=0.00, real=0.00 secs] 315.016: [CMS-concurrent-abortable-preclean-start] 332.055: [GC 332.055: [ParNew: 17128K->84K(19136K), 0.0017700 secs] 88000K->70956K(522176K) icms_dc=4 , 0.0018660 secs] [Times: user=0.00 sys=0.00, real=0.00 secs] CMS: abort preclean due to time 352.253: [CMS-concurrent-abortable-preclean: 0.023/37.237 secs] [Times: user=0.78 sys=0.02, real=37.23 secs] How can I make these log lines appear with an actual timestamp (including date) instead of these numbers, which presumably mean "time since JVM started" ?

  • Objective-C property getter

    - by Daniel
    What is technically wrong with the following: @property(nonatomic, assign) NSUInteger timestamp; @property(nonatomic, readonly, getter = timestamp) NSUInteger startTime; @property(nonatomic, assign) NSUInteger endTime; I am sure I can find a better way to organise this, but this is what I ended up with at one point in my project and I noticed that accessing the startTime property always returned 0, even when the timestamp property was set to a correct timestamp. It seems having set the getter of startTime to an existing property (timestamp), it is not forwarding the value of timestamp when I do: event.startTime => 0 event.timestamp => 1340920893 All these are timestamps by the way. Just a reminder, I know the above should have happened in my project but I don't understand why accessing startTime doesn't forward onto timestamp property. UPDATE In my implementation I am synthesising all of these properties: @synthesize timestamp, endTime, startTime; Please check an example object to use that demonstrates this at my gist on GitHub: https://gist.github.com/3013951

Maybe I dont use it right... ? Thanks guys :)

  • backbonejs remove anomaly concept

    - by user1537158
    I was building a small app for adding and deleting li from ul using Backbonejs.One of the SO members cymen helped me code it, using that i tailored the code a little.currently if i add one element and delete , it works , but the second time i add an element (to ul) and go to delete it , i get Uncaught TypeError: Cannot call method 'remove' of undefined Pasting my code here , HTML : <input type="text" id="name"> <button id="add">Add</button> <ul id="mylist"></ul> JS: $(function(){ var myCollection = Backbone.Collection.extend(); var myView = Backbone.View.extend({ el:$('body'), tagName:'li', initialize : function(e){ this.collection.bind("add",this.render,this); this.collection.bind("remove",this.render,this); }, events:{ 'click #add' : 'addfoo' }, addfoo : function(){ var myname= $('#name').val(); $('#name').val(''); this.collection.add({name:myname}); }, render : function(){ $('#mylist').empty(); this.collection.each(function(model){ console.log("myView"); var remove = new myRemoveView({model:model}); remove.render(); }); } }); var myRemoveView = Backbone.View.extend({ el:$('body'), events:{ 'click .button':'removeFoo' }, removeFoo : function(){ console.log("here"); this.model.collection.remove(this.model); }, render : function(){ console.log("second view"); $('#mylist').append('<li>'+this.model.get('name') + "<button class='button'>"+"delete"+"</button></li>"); return; } }); var view = new myView({collection: new myCollection()}); }); Two things i did not understand : i) in the removeFoo function , we write this.model.collection.remove(this.model) shouldnt this have been this.collection.model.remove , something of that sort ? ii) i add a li to ul , then i delete it , when i add another li (appending to ul works perfect) but this time when i go to delete it throws me the above error : Uncaught TypeError :cannot call method 'remove' of undefined can you please help me figure out these 2 doubts in my code , btw SO member cymen's code works like a charm only my tailored code (above) is giving me errors. SO member cymen's code : JS Fiddle for his code Thank you

  • Attach to Property's setter

    - by StupidDeveloper
    I haven't found similiar post so I'm asking this. Let's say I defined somewhere an application wide available static Property (I mean it's not local) and in one class I would like to know when this property is being changed. Apart from aop (transparentproxy etc.) which I think doesn't suit me well here (and I can't add that to project anyway), what are the options here? One solution I can think of, which is probably a very nasty one, is to use some event that would be executed in the setter and just attach it in the class(es) which needs that. Something like: public static event EventHandler CurrentNumberChanged= delegate {}; public static int CurrentNumber { get { return currentNumber; } set { currentNumber = value; CurrentNumberChanged(null, EventArgs.Empty); } } I know it's really unsafe to use such events ( read here ). And since I would use it in asp.net makes it even more ugly. Do you have any advices ?

  • [Flash 3d engine] Away3d and events (Basic questions)

    - by Simon
    I'd like to play around 3d in Flash and I'm wondering how sophisticated objects can i load from 3D Max... cos as i read it's possible to load something from 3d Max I've read that popular 3d engine is Away3d (many tutorials), so if there is nothing better... i'd like to focus on it. I've forgot to mention that i'm not familar with Flash, but the best way to learn something is to do something interesting with it... :) Main question: Can I load object from 3ds and link parts of this object to some actions in Flash. Better example: I'd like to load a Car and when user click on car's door i'd like to show some informations, about those door, or pass this event outside for example to any other application in PHP, Java etc... and when he click on car mask i'd like to raise other event... Is it possible to create such interaction?? Thx in advance :)

  • Elegant way to add functionallity to previously defined functions

    - by Bastiaan
    How to combine two functions together I have a class controlling some hardware: class Heater() def set_power(self,dutycycle, period) ... def turn_on(self) ... def turn_off(self) And a class that connects to a database and handles all data logging fuctionallity for an experiment: class DataLogger() def __init__(self) # Record measurements and controls in a database def start(self,t) # Starts a new thread to aqcuire and reccord measuements every t secconds Now, in my program recipe.py I want to do something like: log = DataLogger() @DataLogger_decorator H1 = Heater() log.start(60) H1.set_power(10,100) H1.turn_on() sleep(10) H1.turn_off() etc Where all actions on H1 are recorded by the datalogger. I can change any of the classes involved, just looking for an elegant way to do this. Ideally the hardware functions remain separated from the database and DataLogger functions. And ideally the DataLogger is reusable for other controls and measurements.

  • Logging on to two sites simultaneously

    - by James Wakefield
    I want to log on to two sites simultaneously to enable a single sign on solution. We have a smallish wiki that is created with Apple wiki and we have an intranet site on a aspx cms system by Elcom. Both use Active Directory for credentials. Currently they are on different domains, but we could enable a rewrite using our load-balancer (Citrix Netscaler) or IIS. These sites are on different servers, one a mysterious Mac system and the other an IIS v6.0 on windows 2003. Now I am almost certain that a reverse proxy set up will solve this but I really just need someone to agree that this solves this issue, and if there are things I should look out for what they might be. I just want to have an invisible log on screen in an iframe and enter clone the user name and password using javascript.

  • Click Listener not invoked within ListFragment

    I'm extending a SherlockListFragment, but it should not matter as my question seems to be more general related to Fragments. Now, I implement a simple click listener for my list, but it does not get called. public class MyListFragment extends SherlockListFragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View v = inflater.inflate(R.layout.list, container, false); v.setOnClickListener(new OnClickListener() { public void onClick(View view) { Log.i("debug", "single click"); } }); return v; } } Is anything wrong with this? //Solution: listView.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Log.i("debug", "single click"); } });
