  • Insert something .after a set of elements if the first in the set has a certain class.

    - by Adripants
    I would like to add a label AFTER a group of radio inputs IF the first has a certain class <label>Has the strategy and all of it's relevant background documents been uploaded</label> <label for="Radio1"><input type="radio" name="uploaded" class="required cat1" id="Radio1">Yes</label> <label for="Radio2"><input type="radio" name="uploaded" id="Radio2">No</label> Radio1 has the class, but I'd like to insert a label after the last (in this case Radio2) I thought I could use this: $('input[type="radio"].cat1').siblings('input:last').after('<label>Hi!</label>'); But it doesn't work. Can you pick what I am doing wrong?

  • What characters are widely supported in CSS class names?

    - by last-child
    As detailed here among other places, the only valid characters in a html/css class name is a-z, A-Z, 0-9, hyphen and underscore, and the first character should be a letter. But in practice, what characters are in fact supported by most browsers? More specifically, I wonder what browsers properly understands a slash (/) in a class name, and what browsers support class names starting with a number. I'm primarily interested in getting an answer for html rather than xhtml, in case there is a difference. Thank you.

  • How do I write a writer method for a class variable in Ruby?

    - by tepidsam
    I'm studying Ruby and my brain just froze. In the following code, how would I write the class writer method for 'self.total_people'?

  • How do I supply values to an referenced assembly without calling a method it explicitly?

    - by Rob
    Currently I have a static class that I use as my logging module. I’ve added the class to my visual studio solution. Within the class I’ve specified the name and location of the log file to use. Which lets me do stuff like this – which I like and want. Logger.Information(“Page_Load”,”controls loaded correctly”); I’d like to refactor the code and move the logging functionality into a separately compiled assembly, if I did this I would then need to pass in the log file name and location to save the files too. However I don’t want to have to supply this information every time I call the ‘Logging’ method, this would be bad... Logger.Informtaion(“Page_Load”,”controls loaded correctly”,”logfile.txt”,”c:\temp”); Is there any way I can supply this information without having to specify it within each page or via the method call.

  • Sharing object between 2 classes

    - by Justin
    I am struggling to wrap my head around being able to share an object between two classes. I want to be able to create only one instance of the object, commonlib in my main class and then have the classes, foo1 and foo2, to be able to mutually share the properties of the commonlib. commonlib is a 3rd party class which has a property Queries that will be added to in each child class of bar. This is why it is vital that only one instance is created. I create two separate queries in foo1 and foo2. This is my setup: abstract class bar{ //common methods } class foo1 extends bar{ //add query to commonlib } class foo2 extends bar{ //add query to commonlib } class main { public $commonlib = new commonlib(); public function start(){ //goal is to share one instance of $this->commonlib between foo1 and foo2 //so that they can both add to the properites of $this->commonlib (global //between the two) //now execute all of the queries after foo1 and foo2 add their query $this->commonlib->RunQueries(); } }

  • Should if statments be in inner or outer method?

    - by mjcopple
    Which of these designs is better? What are the pros and cons of each? Which one would you use? Any other suggestions of how to deal with methods like is are appreciated. It is reasonable to assume that Draw() is the only place that the other draw methods are called from. This needs to expand to many more Draw* methods and Show* properties, not just the three shown here. public void Draw() { if (ShowAxis) { DrawAxis(); } if (ShowLegend) { DrawLegend(); } if (ShowPoints && Points.Count > 0) { DrawPoints(); } } private void DrawAxis() { // Draw things. } private void DrawLegend() { // Draw things. } private void DrawPoints() { // Draw things. } Or public void Draw() { DrawAxis(); DrawLegend(); DrawPoints(); } private void DrawAxis() { if (!ShowAxis) { return; } // Draw things. } private void DrawLegend() { if (!ShowLegend) { return; } // Draw things. } private void DrawPoints() { if (!ShowPoints || Points.Count <= 0)) { return; } // Draw things. }

  • Is there a version control system that can show changes to a specific method or function?

    - by chesles
    Sometimes it would be nice to be able to say something like: (git|svn|hg|etc) diff Foo.c:main (git|svn|hg|etc) log log Foo.c:main to see the changes made to a specific function within a source file since the last commit, or the complete history of changes. My question is two-fold: Does something exist that does this? Would such a tool be practical? It would have to do some simple parsing of the code at each revision in order to compare different versions of the function; would the overhead be too much for it to be efficient?

  • Is there anything wrong with a class with all static methods?

    - by MatthewMartin
    I'm doing code review and came across a class that uses all static methods. The entrance method takes several arguments and then starts calling the other static methods passing along all or some of the arguments the entrance method received. It isn't like a Math class with largely unrelated utility functions. In my own normal programming, I rarely write methods where Resharper pops and says "this could be a static method", when I do, they tend to be mindless utility methods. Is there anything wrong with this pattern? Is this just a matter of personal choice if the state of a class is held in fields and properties or passed around amongst static methods using arguments?

  • Using a custom annotation on a Spring MVC controller method from an interceptor.

    - by Speck
    I have a custom annotation with which I've annotated a method in my Controller alongside a @ReqestMapping. The goal is to use the values set in the custom annotation from a HandlerInterceptor to perform a task. I have the interceptor (HandlerInterceptorAdaptor) mapped and it executes. If I set a breakpoint in my concrete Interceptor I can inspect the HttpServletRequest, HttpServletResponse, and handler Objects. However, I cannot see how to 1, obtain the method which the request is trying to access 2, obtain the Annotations on that method and 3, of course, obtain the values set by the annotation. Can anyone point me to good documentation for this? Please and Thank You.

  • 2 compareTo method overriden in the same class definition, how could I force to use the second?

    - by jayjaypg22
    I want to sort a list List<Blabla> donnees by a criterion on one of its field. My problem is that compareTo is already overriden for this Class. So I've got something like : Blabla { public int compareTo(Object other) { ... } public int compareTo(Blabla other) { ... } } In a business layer class I call : Business { method (){ Collections.sort(List<Blabla > donnees); } } But this call N°1 compareTo method with object parameter. How could I sort my list with the N°2 method?

  • Secure C# Assemblies from unauthorized Callers

    - by Creepy Gnome
    Is there any way to secure your assembly down to the class/property & class/method level to prevent the using/calling of them from another assembly that isn't signed by our company? I would like to do this without any requirements on strong naming (like using StrongNameIdentityPermission) and stick with how an assembly is signed. I really do not want to resort to using the InternalsVisibleTo attribute as that is not maintainable in a ever changing software ecosystem. For example: Scenario One Foo.dll is signed by my company and Bar.dll is not signed at all. Foo has Class A Bar has Class B Class A has public method GetSomething() Class B tries to call Foo.A.GetSomething() and is rejected Rejected can be an exception or being ignored in someway Scenario Two Foo.dll is signed by my company and Moo.dll is also signed by my company. Foo has Class A Moo has Class C Class A has public method GetSomething() Class C tries to call Foo.A.GetSomething() and is not rejected

  • How do i change Object to String in a class which extends AsyncTask?

    - by Filip V.
    I'm learning from Google's Android developing tutorial and i came across a problem. On this link https://developer.android.com/training/basics/network-ops/connecting.html#AsyncTask it says to create a class that extends AsyncTask. So when i write the class it automatically implements the method as follows: private Object doInBackground(Object... args) {..} //it's fine but when i try writing just as it says in the tutorial: private String doInBackground(String... args) {..} //it gives an error and the error says: The method doInBackground(String...) of type MainActivity.DownloadWebpageText must override a superclass method. So how do i change Object to String without getting an error there?

  • What to do when using Contract.Assert(true) and the method must return something?

    - by devoured elysium
    I have a bit of code with the following logic: //pseudo-code foreach (element in elementList) { if (element is whatever) return element; } } In theory, there is always one element that is whatever, so this method should pose no problems. In any case, I've put an assertion on the end of the method just to be sure: //pseudo-code foreach (element in elementList) { if (element is whatever) return element; } } Contract.Assert(true, "Invalid state!"); The problem is that as this method has to return something, and the compiler doesn't understand that the assertion will break the program execution. Before using Contracts, in these kind of situations, I used to throw an Exception, which solved the problem. How would you handle this with Contract.Assert()? Returning null or default(element_type) after the Contract.Assert() call knowing it will never be called and shutting up the compiler? Or is there any other more elegant way of doing this? Thanks

  • Is it possible to retrieve only a single property from a CSS class?

    - by werner5471
    Example CSS File: .testClass { color: black; background: red; } Now in an HTML file, I would like to have something like <span class="testClass:color">Text in black but without red background</span> to only apply the color property of that class. Is there a way to do this? The purpose behind it (for people asking themselves "Why the hell would he want that, that's not clean CSS usage!") is that I use jQuery UI themes, and I would like the entire page to fit a theme upon change. As not all kinds of elements (e.g. the color of a link) are covered by those themes, in those cases I would like to "steal" the color property (but not more) of some other CSS class of the jQuery UI theme. If there is another way to do this, of course I'm glad to hear it as well!

  • Why is my animation getting aborted?

    - by Homer_Simpson
    I have a class named Animation which handles my animations. The animation class can be called from multiple other classes. For example, the class Player.cs can call the animation class like this: Animation Playeranimation; Playeranimation = new Animation(TimeSpan.FromSeconds(2.5f), 80, 40, Animation.Sequences.forwards, 0, 5, false, true); //updating the animation public void Update(GameTime gametime) { Playeranimation.Update(gametime); } //drawing the animation public void Draw(SpriteBatch batch) { playeranimation.Draw(batch, PlayerAnimationSpritesheet, PosX, PosY, 0, SpriteEffects.None); } The class Lion.cs can call the animation class with the same code, only the animation parameters are changing because it's another animation that should be played: Animation Lionanimation; Lionanimation = new Animation(TimeSpan.FromSeconds(2.5f), 100, 60, Animation.Sequences.forwards, 0, 8, false, true); Other classes can call the animation class with the same code like the Player class. But sometimes I have some trouble with the animations. If an animation is running and then shortly afterwards another class calls the animation class too, the second animation starts but the first animation is getting aborted. In this case, the first animation couldn't run until it's end because another class started a new instance of the animation class. Why is an animation sometimes getting aborted when another animation starts? How can I solve this problem? My animation class: public class Animation { private int _animIndex, framewidth, frameheight, start, end; private TimeSpan PassedTime; private List<Rectangle> SourceRects = new List<Rectangle>(); private TimeSpan Duration; private Sequences Sequence; public bool Remove; private bool DeleteAfterOneIteration; public enum Sequences { forwards, backwards, forwards_backwards, backwards_forwards } private void forwards() { for (int i = start; i < end; i++) SourceRects.Add(new Rectangle(i * framewidth, 0, framewidth, frameheight)); } private void backwards() { for (int i = start; i < end; i++) SourceRects.Add(new Rectangle((end - 1 - i) * framewidth, 0, framewidth, frameheight)); } private void forwards_backwards() { for (int i = start; i < end - 1; i++) SourceRects.Add(new Rectangle(i * framewidth, 0, framewidth, frameheight)); for (int i = start; i < end; i++) SourceRects.Add(new Rectangle((end - 1 - i) * framewidth, 0, framewidth, frameheight)); } private void backwards_forwards() { for (int i = start; i < end - 1; i++) SourceRects.Add(new Rectangle((end - 1 - i) * framewidth, 0, framewidth, frameheight)); for (int i = start; i < end; i++) SourceRects.Add(new Rectangle(i * framewidth, 0, framewidth, frameheight)); } public Animation(TimeSpan duration, int frame_width, int frame_height, Sequences sequences, int start_interval, int end_interval, bool remove, bool deleteafteroneiteration) { Remove = remove; DeleteAfterOneIteration = deleteafteroneiteration; framewidth = frame_width; frameheight = frame_height; start = start_interval; end = end_interval; switch (sequences) { case Sequences.forwards: { forwards(); break; } case Sequences.backwards: { backwards(); break; } case Sequences.forwards_backwards: { forwards_backwards(); break; } case Sequences.backwards_forwards: { backwards_forwards(); break; } } Duration = duration; Sequence = sequences; } public void Update(GameTime dt) { PassedTime += dt.ElapsedGameTime; if (PassedTime > Duration) { PassedTime -= Duration; } var percent = PassedTime.TotalSeconds / Duration.TotalSeconds; if (DeleteAfterOneIteration == true) { if (_animIndex >= SourceRects.Count) Remove = true; _animIndex = (int)Math.Round(percent * (SourceRects.Count)); } else { _animIndex = (int)Math.Round(percent * (SourceRects.Count - 1)); } } public void Draw(SpriteBatch batch, Texture2D Textures, float PositionX, float PositionY, float Rotation, SpriteEffects Flip) { if (DeleteAfterOneIteration == true) { if (_animIndex >= SourceRects.Count) return; } batch.Draw(Textures, new Rectangle((int)PositionX, (int)PositionY, framewidth, frameheight), SourceRects[_animIndex], Color.White, Rotation, new Vector2(framewidth / 2.0f, frameheight / 2.0f), Flip, 0f); } }

  • How to invoke RESTful WCF service method with multiple parameters?

    - by Scythe
    I have a RESTful WCF service with a method declared like this: [OperationContract(Name = "IncrementAge")] [WebInvoke(UriTemplate = "/", Method = "POST", ResponseFormat = WebMessageFormat.Json)] Person IncrementAge(Person p); Here's the implementation: public Person IncrementAge(Person p) { p.age++; return p; } So it takes the Person complex type, increments the age property by one, and spits it back, using JSON serialization. I can test the thing by sending a POST message to the service like this: POST http://localhost:3602/RestService.svc/ HTTP/1.1 Host: localhost:3602 User-Agent: Fiddler Content-Type: application/json Content-Length: 51 {"age":25,"firstName":"Hejhaj","surName":"Csuhaj"} This works. What if I'd like to have a method like this? Person IncrementAge(Person p, int amount); So it'd have multiple parameters. How should I construct the POST message for this to work? Is this possible? Thanks

  • How to use jQuery to generate 2 new associated objects in a nested form?

    - by mind.blank
    I have a model called Pair, which has_many :questions, and each Question has_one :answer. I've been following this railscast on creating nested forms, however I want to generate both a Question field and it's Answer field when clicking on an "Add Question" link. After following the railscast this is what I have: ..javascripts/common.js.coffee: window.remove_fields = (link)-> $(link).closest(".question_remove").remove() window.add_fields = (link, association, content)-> new_id = new Date().getTime() regexp = new RegExp("new_" + association, "g") $(link).before(content.replace(regexp, new_id)) application_helper.rb: def link_to_add_fields(name, f, association) new_object = f.object.class.reflect_on_association(association).klass.new fields = f.simple_fields_for(association, new_object, :child_index => "new_#{association}") do |builder| render(association.to_s.singularize + "_fields", :f => builder) end link_to_function(name, "window.add_fields(this, \"#{association}\", \"#{escape_javascript(fields)}\")", class: "btn btn-inverse") end views/pairs/_form.html.erb: <%= simple_form_for(@pair) do |f| %> <div class="row"> <div class="well span4"> <%= f.input :sys_heading, label: "System Heading", placeholder: "required", input_html: { class: "span4" } %> <%= f.input :heading, label: "User Heading", input_html: { class: "span4" } %> <%= f.input :instructions, as: :text, input_html: { class: "span4 input_text" } %> </div> </div> <%= f.simple_fields_for :questions do |builder| %> <%= render 'question_fields', f: builder %> <% end %> <%= link_to_add_fields "<i class='icon-plus icon-white'></i> Add Another Question".html_safe, f, :questions %> <%= f.button :submit, "Save Pair", class: "btn btn-success" %> <% end %> _question_fields.html.erb partial: <div class="question_remove"> <div class="row"> <div class="well span4"> <%= f.input :text, label: "Question", input_html: { class: "span4" }, placeholder: "your question...?" %> <%= f.simple_fields_for :answer do |builder| %> <%= render 'answer_fields', f: builder %> <% end %> </div> </div> </div> _answer_fields.html.erb partial: <%= f.input :text, label: "Answer", input_html: { class: "span4" }, placeholder: "your answer" %> <%= link_to_function "remove", "remove_fields(this)", class: "float-right" %> I'm especially confused by the reflect_on_association part, for example how does calling .new there create an association? I usually need to use .build Also for a has_one I use .build_answer rather than answers.build - so what does this mean for the jQuery part?

  • What's the deal with a leading underscore in PHP class methods?

    - by nocash
    While looking over various PHP libraries I've noticed that a lot of people choose to prefix some class methods with a single underscore, such as public function _foo() ...instead of... public function foo() I realize that ultimately this comes down to personal preference, but I was wondering if anyone had some insight into where this habit comes from. My thought is that it's probably being carried over from PHP 4, before class methods could be marked as protected or private, as a way of implying "do not call this method from outside the class". However, it also occurred to me that maybe it originates somewhere (a language) I'm not familiar with or that there may be good reasoning behind it that I would benefit from knowing. Any thoughts, insights and/or opinions would be appreciated.

  • c# class design - what can I use instead of "static abstract"?

    - by Ryan
    I want to do the following public abstract class MyAbstractClass { public static abstract int MagicId { get; } public static void DoSomeMagic() { // Need to get the MagicId value defined in the concrete implementation } } public class MyConcreteClass : MyAbstractClass { public static override int MagicId { get { return 123; } } } However I can't because you can't have static abstract members. I understand why I can't do this - any recommendations for a design that will achieve much the same result? (For clarity - what I am trying to do is provide a library with an abstract base class but the concrete versions MUST implement a few properties/methods themselves and yes, there are good reasons for keeping it static.)

  • Dynamic menu items (change text on click)

    - by Mathijs Delva
    Hello, i need some help with a menu. See the following menu: menu The code for this menu: <div id="menu"> <ul> <li class="home"><a href="#home" class="panel">home / <span class="go">you are here</span></a></li> <li class="about"><a href="#about" class="panel">about / <span class="go">go here</span></a></li> <li class="cases"><a href="#cases" class="panel">cases / <span class="go">go there</span></a></li> <li class="photos"><a href="#photos" class="panel">photos / <span class="go">maybe here</span></a></li> <li class="contact"><a href="#contact" class="panel">contact / <span class="go">or even here<span></span></a></li> </ul> </div> What i want to do: onclick a menu item: 1. change the red text to yellow 'you are here' 2. change the previous menu item back to its original state (eg red and "go here"). The 4 values "go here", "go there", "maybe here", "or even here" are the 4 values that should be assigned to the other menu items (like the example). This is the code i already have: $('#menu ul li.home').addClass('active') $('#menu ul li.active a .go').html("you are here"); $("#menu ul li").click(function () { $('#menu ul li.active').removeClass('active'); $(this).addClass('active'); $('#menu ul li.active a .go').html("you are here"); }); var arr = [ "go here", "go there", "maybe here", "or even here" ]; var obj = { item1: "go here", item2: "go there" ,item3: "maybe here", item4: "or even here"}; $('#menu ul li').click(function () { var str = $('#menu ul li.active a .go').text(); $('#menu ul li.active a .go').html(str); }); As you see, it's incomplete. I don't how to get the values from the array and assign them too a menu item. The replace text works, but not the change-back-to-original-state. Also, right now, for some reason i can't click ONTO the list item itself in order to activate the jquery code. I need to click just a few pixels under it. But i guess that's a css issue. If anyone can help, i'd be super thankful! Regards, Mathijs

  • Good way of handling class instances in game development?

    - by Bugster
    I'm a new indie game developer, and I've made a few games, but often times when coding I wonder "Is this the way most people do it? Am I doing it wrong?" because I'd like to become a game developer some day, and I really want to get rid of bad practices in time. The way I'm doing it right now is like this: #include <some libraries> #include "Some classes" int main() { Class1 a; Class2 b; Class3 c; a.init(); b.init(); c.init(); // game logic; } Now as I see the game grow, I have more and more classes to initialize and create instances of. This is clean but I'm not sure if this is standard practice. Is this a regular way of creating instances of your game classes or is there a cleaner and more efficient way to do it?
