  • jquery run function in infinite loop

    - by zac
    I am creating a background color animation with jQuery and the color animation plugin http://plugins.jquery.com/project/color How do I have a function stay in a loop repeating itself each time it has finished running? I tried this but it did not work : $(document).ready(function(){ function colorLoop(){ $("#window") .animate({ backgroundColor: "orange" }, 11000) .animate({ backgroundColor: "yellow" }, 1000) .animate({ backgroundColor: "green" }, 1000) .animate({ backgroundColor: "blue" }, 1000) .animate({ backgroundColor: "indigo" }, 1000) .animate({ backgroundColor: "violet" }, 1000) .animate({ backgroundColor: "red" }, 1000, colorLoop); }; });

  • C++ meta-splat function

    - by aaa
    hello. Is there an existing function (in boost mpl or fusion) to splat meta-vector to variadic template arguments? for example: splat<vector<T1, T2, ...>, function>::type same as function<T1, T2, ...> my search have not found one, and I do not want to reinvent one if it already exists. edit: after some tinkering, apparently it's next to impossible to accomplish this in general way, as it would require declaring full template template parameter list for all possible cases. only reasonable solution is to use macro: #define splat(name, function) \ template<class T, ...> struct name; \ template<class T> \ struct name<T,typename boost::enable_if_c< \ result_of::size<T>::value == 1>::type> { \ typedef function< \ typename result_of::value_at_c<T,0>::type \ > type; \ }; Oh well. thank you

  • Using Jquery, call function on selection just once

    - by maxp
    Say i have a selection of textboxes like this; var arrayoftextboxes = $('.textbox1, .textbox2, .textbox3'); Is there a way I can call a function on each one in a simpler way than this? It only needs to be called once. arrayoftextboxes.each(function(i){foo(arrayoftextboxes[i]);}); I tried arrayoftextboxes.load(function(){foo(this)}); and arrayoftextboxes.bind(function(){foo(this)}); but the functions dont seem to be called.

  • Template Parameter Initialization

    - by isurulucky
    Hi, I wrote some C++ code in which I used Templates. Since I used templates, I could not initialize a couple of template class variables. I got an warning message from valgrind saying Conditional jump or move depends on uninitialized value(s). So is there a way to get around this and/or initialize template variables?? I couldn't think of a way to do it because even if I initailize them as NULL, when I use string data type a run time failure occurres. Thank You!

    - by Maju
    I need to run a function 'setNotifications()' after a timed delay or at the end of completion of the previous animation('#topannounce' animation).But jQuery is not running the 'setNotifications()'after the animation. What should I do? or is there a better way to run the function?Plz hlp.Thanx. Here is the jQuery I have. $('a#resetbtn').bind('click', function(){ //setNotifications(); $.cookie('notificationBar', 'open'); //$('#topannounce').animate({opacity: 1.0}, 3000).fadeIn('slow'); $('#topannounce').fadeIn('slow'); setNotifications(); }); function setNotifications() { alert("load:setNotifications..."); }

  • Manhattan Heuristic function for A-star (A*)

    - by Shawn Mclean
    I found this algorithm here. I have a problem, I cant seem to understand how to set up and pass my heuristic function. static public Path<TNode> AStar<TNode>(TNode start, TNode destination, Func<TNode, TNode, double> distance, Func<TNode, double> estimate) where TNode : IHasNeighbours<TNode> { var closed = new HashSet<TNode>(); var queue = new PriorityQueue<double, Path<TNode>>(); queue.Enqueue(0, new Path<TNode>(start)); while (!queue.IsEmpty) { var path = queue.Dequeue(); if (closed.Contains(path.LastStep)) continue; if (path.LastStep.Equals(destination)) return path; closed.Add(path.LastStep); foreach (TNode n in path.LastStep.Neighbours) { double d = distance(path.LastStep, n); var newPath = path.AddStep(n, d); queue.Enqueue(newPath.TotalCost + estimate(n), newPath); } } return null; } As you can see, it accepts 2 functions, a distance and a estimate function. Using the Manhattan Heuristic Distance function, I need to take 2 parameters. Do I need to modify his source and change it to accepting 2 parameters of TNode so I can pass a Manhattan estimate to it? This means the 4th param will look like this: Func<TNode, TNode, double> estimate) where TNode : IHasNeighbours<TNode> and change the estimate function to: queue.Enqueue(newPath.TotalCost + estimate(n, path.LastStep), newPath); My Manhattan function is: private float manhattanHeuristic(Vector3 newNode, Vector3 end) { return (Math.Abs(newNode.X - end.X) + Math.Abs(newNode.Y - end.Y)); }

  • Method Overloading for NULL parameter

    - by Phani
    I have added three methods with parameters: public static void doSomething(Object obj) { System.out.println("Object called"); } public static void doSomething(char[] obj) { System.out.println("Array called"); } public static void doSomething(Integer obj) { System.out.println("Array called"); } When I am calling doSomething(null) , then compiler throws error as ambiguous methods. So Is the issue because Integer and char[] methods or Integer and Object methods?

  • OpenOffice Calc Macro: Run shell command and return output as result of custom function

    - by Mark
    I would like to write a custom OpenOffice function that runs a shell command and puts the result into the cell from which it was invoked. I have a basic macro working, but I can't find a way to capture the command's output. Function MyTest( c1 ) MyTest = Shell("bash -c "" echo hello "" ") End Function The above always returns 0. Looking at the documentation of the Shell command, I don't think it actually returns STDOUT. How would I capture the output so that I can return it in my function? Thanks!

  • routine to generate a 2d array from two 1d arrays and a function

    - by intuited
    I'm guessing that there's a word for this concept, and that it's available in at least some popular languages, but my perfunctory search was fruitless. A pseudocode example of what I'd like to do: function foo(a, b) { return a * b // EG } a = [ 1, 2, 3 ] b = [ 4, 5, 6 ] matrix = the_function_for_which_I_search(foo, [a, b] ) print matrix => [ [ 4, 8, 12], [5, 10, 15], [6, 12, 18] ] // or function concatenate(a,b) return a.b } print the_function_for_which_I_search( concatenate, [ a, b ]) => [ [ '14', '24', '34'], ['15', '25', '35'], [16', '26', '36'] ] In other words, function_for_which_I_search will apply the function given as its first argument to each combination of the elements of the two arrays passed as its second argument, and return the results as a two-dimensional array. I would like to know if such a routine has a common name, and if it's available in a python module, cpan package, ruby gem, pear package, etc. I'm also wondering if this is a core function in other languages, maybe haskell or R?

  • Java convert JSONObject to URL parameter

    - by Alex Ivasyuv
    What is the elegant way to convert JSONObject to URL parameters. For example, JSONObject: {stat: {123456: {x: 1, y: 2}, 123457: {z: 5, y: 2}}}} this should be like: stat[123456][x]=1&stat[123456][y]=2&stat[123457][z]=5&stat[123457][y]=2 of course with escaped symbols, and of course JSON object could be more complicated.. Maybe there already exist some mechanisms for that? Thanks,

  • Preprocessor "macro function" vs. function pointer - best practice?

    - by Dustin
    I recently started a small personal project (RGB value to BGR value conversion program) in C, and I realised that a function that converts from RGB to BGR can not only perform the conversion but also the inversion. Obviously that means I don't really need two functions rgb2bgr and bgr2rgb. However, does it matter whether I use a function pointer instead of a macro? For example: int rgb2bgr (const int rgb); /* * Should I do this because it allows the compiler to issue * appropriate error messages using the proper function name, * not to mention possible debugging benefits? */ int (*bgr2rgb) (const int bgr) = rgb2bgr; /* * Or should I do this since it is merely a convenience * and they're really the same function anyway? */ #define bgr2rgb(bgr) (rgb2bgr (bgr)) I'm not necessarily looking for a change in execution efficiency as it's more of a subjective question out of curiosity. I am well aware of the fact that type safety is neither lost nor gained using either method. Would the function pointer merely be a convenience or are there more practical benefits to be gained of which I am unaware?

  • jquery event handler- trigger function upon specific key and action

    - by Gal
    Background story: when a user selects a portion of text in a text field with her mouse (mark it up manually), and subsequently hits "alt" key, a certain function would trigger. My questions are: How can I trigger a function when a user hits a key (in her keyboard)? How can I preserve a portion of text selected, and use it as a parameter for that function? I've tried looking up online but haven't found any good answers, but i'd greatly appreciate links as well.

  • fprintf() within a subprogram

    - by sergio
    Im stuck when trying to write to my file within my subprogram. void new_page(float *a, float *b, float *c, int *d){ fprintf(results,"\nPage Totals: %f\t%f\t%f\t%d", *a,*b,*c,*d); } I get a warning saying "Warning: incompatible implicit declaration of built-in function 'fprinf' [enabled by default]" "error: 'results' undeclared (first use in this function)" in main fprintf works fine, its just when it comes to the subprogram/function it wont work. from my understanding it thinks that results is undeclared, so do i have to pass the name or location of the file to make it work?

  • Pass complex objects to MVC Get parameters

    - by VJ
    I am wanting to pass something like the following to my view from my controller via GET not POST: public class MyDTO { public string val1 { get; set; } public string val2 { get; set; } public MyObject obj { get; set; } } public class MyObject { public int SomeInt { get; set; } public string ACoolValue { get; set; } public string YetAnotherCoolValue { get; set; } } And then the controller would like like this. (Note it is a GET): public ActionResult MyView(MyDTO dto) { return View(dto) } The problem is that the instance of MyObject is coming back as null, where val1 and val2 have data. Has anyone run across this?

  • os.walk in python not running with cmd line parameter passed as path

    - by kartiku
    Hello, I needed to find the number of files in a folder on the system. This is what i used: file_count = sum((len(f) for _, _, f in os.walk('path'))) This works fine when we specify the path as a string in quotes, but when I enter a variable name that holds the path, type(file_count) is a generator object, and hence cannot be used as an integer. How to solve this and why does this happen?

  • Microsoft SQL Server 2005 Function, passing list of start and end times

    - by Kevin
    I'd like to do had a dynamic number of one start/end time pairs passed to a function as an input parameter. The function would then use the list instead of just one start, and one end time in a select statement. CREATE FUNCTION [dbo].[GetData] ( @StartTime datetime, @EndTime datetime ) RETURNS int AS BEGIN SELECT @EndTime = CASE WHEN @EndTime > CURRENT_TIMESTAMP THEN CURRENT_TIMESTAMP ELSE @EndTime END DECLARE @TempStates TABLE (StartTime datetime NOT NULL , EndTime datetime NOT NULL , StateIdentity int NOT NULL ) INSERT INTO @TempStates SELECT StartTime , EndTime , StateIdentity FROM State WHERE StartTime <= @EndTime AND EndTime >= @StartTime RETURN 0 END

  • JSDoc3: How to document a AMD module that returns a function

    - by Jens Simon
    I'm trying to find a way to document AMD modules using JSDoc3. /** * Module description. * * @module path/to/module */ define(['jquery', 'underscore'], function (jQuery, _) { /** * @param {string} foo Foo-Description * @param {object} bar Bar-Description */ return function (foo, bar) { // insert code here }; }); Sadly none of the patterns listed on http://usejsdoc.org/howto-commonjs-modules.html work for me. How can I generate a proper documentation that lists the parameters and return value of the function exported by the module?

  • Anonymous method as function result

    - by iamjoosy
    What I want to do is to assign an anonymous method which I get as a function result to a variable of the same type. Delphi complains about not beeing able to do the assignement. Obviously Delphi things I want to assign the "GetListener" function instead of the result of that same function. Any help with this is very much appreciated. type TPropertyChangedListener = reference to procedure (Sender: TStimulus); TMyClass = class function GetListener:TPropertyChangedListener end; .... var MyClass: TMyClass; Listener: TPropertyChangedListener; begin MyClass:= TMyClass.create; Listener:= MyClass.GetListener; // Delphi compile error: E2010 Incompatible types: TPropertyChangedListener' and 'Procedure of object' end;

  • Repurpose builtin Word commands - access original command within repurposed function

    - by Aurril
    It is possible to repurpose a Word builtin command in Word 2007 using the customUI.xml file. Example: <customUI xmlns="http://schemas.microsoft.com/office/2009/07/customui"> <commands> <command idMso="Save" onAction="MySave"/> </commands> </customUI> I then have to define a callback function in VBA which is used instead of the builtin function: 'Callback for Save onAction Sub MySave(control As IRibbonControl, ByRef cancelDefault) someFancyPreparationFunction oldSaveFunction ' Where, how? someOtherFancyAfterWorkFunction End Sub And here is my problem, if I want to reuse internal functionality in my repurposed Function, I don't know how to access it. My example is trivial and the save could be easily rebuilt by a call to ThisDocument.save but as I said, it is just an example to show the problem. A call to CommandBars.ExecuteMso('Save') would call my repurposed function and not the original one. Any ideas on how to access the internal functionality after repurposing would be very appreciated!

  • Passing value from :locals to link_remote_to

    - by Teef L
    In my edit.haml file, I have =render :partial => 'old_question_tags', :locals => {:current_question => @question.id}.

How do I properly pass that value to the partial so that I can pass it to the link_to_remote call?
