• IE error with jquery counter plugin

  - by Mankey

  I've implemented a jquery counter script (count up from say 50 to 100 with different increments) that I found from this question: jQuery counter to count up to a target number The scripts works great except for in Internet Explorer 8 (and possibly other IE versions?). Here's an error message from IE with the URL to the creator of the script's demo. Message: 'undefined' is null or not an object Line: 32 Char: 17 Code: 0 URI: http://www.ulmanen.fi/stuff/counter.php I'm just wondering if anyone know how this can be fixed. I'm guessing it has to do with el.html() not finding any data but I can't really figure this out. Thanks for any help ^^ I would reply to that post if I could but I can't seem to find any way of doing so (I'm new to stackoverflow, I think I lack privileges).

• Jquery ajax load of JSON in unit tests

  - by wmitchell

  I'm trying to load a dataset in jasmine for my tests like such ... However as its a json call I cant seem to always get the test denoted by "it" to wait till the JSON call has finished before using its array. I tried using the ajaxStop function to no avail. Any ideas ? describe("simple checks", function() { var exampleArray = new Array(); beforeEach(function(){ $(document).ajaxStop(function() { $(this).unbind("ajaxStop"); $.getJSON('/jasmine/obj.json', function(data) { $.each( json.jsonattr, function(i, widgetElement) { exampleArray.push(new widget(widgetElement)); }); }); }); }); it("use the exampleArray", function() { doSomething(exampleArray[0]); // frequently this is coming up as undefined });

• NodeJS vm.runInThisContext() and lack of __filename

  - by rFactor

  Whenever I run vm.runInThisContext(code, filename), the ran code reports __filename and __dirname as undefined. This also leads to the situation that any fs.readFile and such calls will not work with relative paths. For example this does not work: fs.readFile('../file', fn); because it does not know where to relate the path to. Specifying the filename as /home/full/path/to/file.js for vm.runInThisContext function does not seem to matter at all. How can I make Node to understand the path to the file?

• Accessing rails flash[:notice] in a model

  - by titaniumdecoy

  I am trying to assign a message to flash[:notice] in a model observer. This question has already been asked: Ruby on Rails: Observers and flash[:notice] messages? However, I get the following error message when I try to access it in my model: undefined local variable or method `flash' for #<ModelObserver:0x2c1742c> Here is my code: class ModelObserver < ActiveRecord::Observer observe A, B, C def after_save(model) puts "Model saved" flash[:notice] = "Model saved" end end I know the method is being called because "Model saved" is printed to the terminal. Is it possible to access the flash inside an observer, and if so, how?

• PHP won't parse MySQL statements

  - by Hussain

  I just installed Apache 2.2.15/PHP 5.3.2/MySQL 5.1.44 on Windows Vista. Apache is working fine, PHP is functional, and MySQL works on the CLI. However, when I try to access MySQL via PHP, I get an error (Fatal error: Call to undefined function mysql_connect()). extension=php_mysql.dll and extension=php_mbstring.dll are uncommented in the php.ini file, and PHP is in the system path. There is no libmysql.dll in either the top level PHP directory or the ext directory. There's a libmySQL.dll file in the MySQL bin directory (which is also in the system path); I tried renaming it, but that doesn't do anything Also, in case anyone wants to know, I originally installed PHP using the MSI installer, but it was missing some DLLs, so I installed from the zip file. I think I've exhausted all my options. Any help on this problem would be very appreciated. Thanks in advance.

How do I do this. Thanks.

• Supervising multiple gen_servers with same module / different arguments

  - by Justin

  Hi, I have a OTP application comprising a single supervisor supervising a small number of gen_servers. A typical child specification is as follows: {my_server, {my_server, start_link, [123]}, permanent, 5000, worker, [my_server]} No problems so far. I now want to an add extra gen_server to the supervisor structure, using the same module Module/Fn as above, but different arguments, eg {my_server_2, {my_server, start_link, [123]}, permanent, 5000, worker, [my_server_2]} I thought this would work, but no: =SUPERVISOR REPORT==== 15-Apr-2010::16:50:13 === Supervisor: {local,my_sup} Context: start_error Reason: {already_started,<0.179.0>} Offender: [{pid,undefined}, {name,my_server_2}, {mfa,{my_server,start_link,[]}}, {restart_type,permanent}, {shutdown,5000}, {child_type,worker}] Do the module arguments in the second element of each child specification need to be different ? Thanks, Justin

• How to find modal dialog opener from javascript?

  - by yapiskan

  I have a page that opens a modal dialog. After the operations done on dialog I want to refresh the opener page. But when I open the popup by using "openDialog" I cannot access to the opener by using window.opener on popup page. It appears "undefined" when I wanted to access. (I dont want to use "popup" method in this case. I want it to be a dialog by the way. using "popup" is my second plan.) What is the best practice to get rid off this issue?

• Weird behaviour with vector::erase and std::remove_if with end range different from vector.end()

  - by Edison Gustavo Muenz

  Hi, I need to remove elements from the middle of a std::vector. So I tried: struct IsEven { bool operator()(int ele) { return ele % 2 == 0; } }; int elements[] = {1, 2, 3, 4, 5, 6}; std::vector<int> ints(elements, elements+6); std::vector<int>::iterator it = std::remove_if(ints.begin() + 2, ints.begin() + 4, IsEven()); ints.erase(it, ints.end()); After this I would expect that the ints vector have: [1, 2, 3, 5, 6]. In the debugger of Visual studio 2008, after the std::remove_if line, the elements of ints are modified, I'm guessing I'm into some sort of undefined behaviour here. So, how do I remove elements from a Range of a vector?

• jQuery wait for ajax call to be over before continuing

  - by Flo

  Hi all, I have a problem with a jQuery ajax call. I need to wait for the call to be finished in order to return a value. However, the script seems to jump ahead and not wait for the call to be over. my function then returns "undefined". I have tried to use the .ajax() method and set the value of async to false, but this would not work either. I could I get my function to return the value that I could through the ajax call? Thank you! Here is the code: function get_rsrce_name(){ jQuery.post( '<?php echo admin_url( 'admin-ajax.php' ); ?>', { action :'my_action', option_rsrce : 'option_rsrce' }, function( data ) { output = data.option_name; }, "json" ); return output; }

• Read out result of a PageMethod into a jQuery-script

  - by Jan-Frederik Carl

  Hello, I am quite a jQuery novice and try to read out the result of a PageMethod into my jQuery script. I have a ScriptManager installed and the following WebMethod: [WebMethod(EnableSession = true)] public static string CheckSystemDefault(string _id) { int id = Convert.ToInt16(_id); addressTypeRepository = new AddressTypeRepository(); AddressType addressType = addressTypeRepository.GetById(id); if (addressType.IsSystemDefault == true) return "IsSystemDefault"; else return "IsNotSystemDefault"; } I use this to check if an object has the property IsSystemDefault. In the script, I hand over the id from the url and want to evaluate the result: var id = $(document).getUrlParam("id"); var check = PageMethods.CheckSystemDefault(id); if (check == "IsSystemDefault") { ... } if (check == "IsNotSystemDefault") { ... } But as a result, the variable "check" is undefined. What do I have to change?

• Can I access the function body of an event listener using nodeJS jsdom

  - by Zhami

  I am using jsdom with nodeJS. I load in a large HTML document, and am using jQuery to navigate the DOM. I have a case where I have an element, and I need to access the function body of an event listener (onclick). The event listener was added in the source HTML: <a href="#" onclick="javascript:window.open('http://<rest-of-url>'); return false;"></a> The onclick attribute of the DOM element is undefined. btw: what I really want to do is get the URL (please note that <rest-of-url> is not what is in the source, a real URL spec is there) that is specified in the source.

• How can I specify my own Rhino context in Java?

  - by Dan Howard

  I'm trying to ensure that my Rhino scripts (running under Java 6) are strict so that if a script developer misspells an expression I want an exception to be thrown. Currently what happens is the expression simply evaluates to "undefined". Now according to Mozilla org https://developer.mozilla.org/en/New_in_Rhino_1.6R6 there are features to enable strict checking in the context. I cannot find a working example of this. What I did so far was write a class to extend ContextFactory and then override the hasFeature method. public class ScriptContextFactory extends ContextFactory { protected boolean hasFeature(Context context, int featureIndex) { switch (featureIndex) { case Context.FEATURE_STRICT_EVAL: return true; case Context.FEATURE_STRICT_VARS: return true; } return super.hasFeature(context, featureIndex); } } Then in the Main I set mine to the default. ContextFactory.initGlobal(new ScriptContextFactory()); and I get an illegal state exception. :( Any ideas or samples on how this works? TIA

• Flex 3 / ColdFusion Session Issue?

  - by dcolumbus

  Alright so this is an odd one... I have an application built in ColdFusion with a lot of the interactivity done with Flex. When a user logs in, there are session variables, as well as the client session that is evoked. When you browse to any given Flex Application, the variables are read in a used accordingly... however, on Windows (it seems XP and maybe others) for some reason session information like USER are randomly undefined... Could this be an issue with the session timing out? Even if I force a logout and log back in, it doesn't really seem to fix the issue... mind you, I cannot duplicate the bug myself, but it constantly happens on PCs.

• how to have defined connection within function for pdo communication with DB

  - by Scarface

  hey guys I just started trying to convert my query structure to PDO and I have come across a weird problem. When I call a pdo query connection within a function and the connection is included outside the function, the connection becomes undefined. Anyone know what I am doing wrong here? I was just playing with it, my example is below. include("includes/connection.php"); function query(){ $user='user'; $id='100'; $sql = 'SELECT * FROM users'; $stmt = $conn->prepare($sql); $result=$stmt->execute(array($user, $id)); // now iterate over the result as if we obtained // the $stmt in a call to PDO::query() while($r = $stmt->fetch(PDO::FETCH_ASSOC)) { echo "$r[username] $r[id] \n"; } } query();

• correct way to store an exception in a variable

  - by Evan Teran

  I have an API which internally has some exceptions for error reporting. The basic structure is that it has a root exception object which inherits from std::exception, then it will throw some subclass of that. Since catching an exception thrown in one library and catching it in another can lead to undefined behavior (at least Qt complains about it and disallows it in many contexts). I would like to wrap the library calls in functions which will return a status code, and if an exception occurred, a copy of the exception object. What is the best way to store an exception (with it's polymorphic behavior) for later use? I believe that the c++0x futures API makes use of something like this. So what is the best approach? The best I can think of is to have a clone() method in each exception class which will return a pointer to an exception of the same type. But that's not very generic and doesn't deal with standard exceptions at all. Any thoughts?

• How do I use compiler intrinsic __fmul_?

  - by Eric Thoma

  I am writing a massively parallel GPU application. I have been optimizing it by hand. I received a 20% performance increase with _fdividef(x, y), and according to The Cuda C Programming Guide (section C.2.1), using similar functions for multiplication and adding is also beneficial. The function is stated as this: "_fmulrn,rz,ru,rd". __fdividef(x,y) was not stated with the arguments in brackets. I was wondering, what are those brackets? If I run the simple code: int t = __fmul_(5,4); I a compiler error about how _fmul is undefined. I have the CUDA runtime included, so I don't think it is a setup thing; rather it is something to do with those square brackets. How do I correctly use this function? Thank you.

Thank you very much in advance.
