• Javascript - Jquery .load() and setInterval() issue.

  - by Joe

  Let's say I do this: $("#content").load(...); Within what I'm loading some javascript is included: var myCounter = 0; var myInterval = setInterval(function(){ myCounter++; $("#counter-display").html("Count: "+myCounter); }); For an unknown reason, if I reload the content with $("#content").load(...); - myInterval is now being called twice. I tried doing something like: if (myInterval !== undefined){ //dont set interval again } However, it doesn't work. Does anyone know any method so that myInterval is cleared on .load, without needing to put the javascript outside of the loaded file?

• Importing ctype; embedding python in C++ application

  - by Drew

  I'm trying to embed python within a C++ based programming language (CCL: The compuatational control language, not that any of you have heard of it). Thus, I don't really have a "main" function to make calls from. I have made a test .cc program with a main, and when I compile it and run it, I am able to import my own python modules and system modules for use. When I embed my code in my CCL-based program and compile it (with g++), it seems I have most functionality, but I get the import error: ImportError: /usr/lib/python2.6/lib-dynload/_ctypes.so: undefined symbol: PyType_GenericNew Can someone explain this to me and how to go about solving it? It seems like I've linked the objects correctly. Thanks.

• An analog of String.Join(string, string[]) for List<T> or other generic enumerable

  - by abatishchev

  class String contains very useful method - String.Join(string, string[]). It creates a string from an array, separating each element of array with a symbol given. But general - it doesn't add a separator after the last element! I uses it for ASP.NET coding for separating with "<br />" or Environment.NewLine. So I want to add an empty row after each row in asp:Table. What method of IEnumerable<TableRow> can I use for the same functionality?

• Accessing GMail "View as HTML" content programatically?

  - by Amethi

  I love the "View as HTML" option in GMail when viewing attachments. I would love to be able to use this feature programatically, i.e. check a GMail inbox, read emails, if there are attachments, get the html view and use that content. I'm looking to do this in C Sharp (on a Mac, can't find the hash symbol). Does anyone know if this is possible or if there's another solution to easily get content from a GMail account, regardless of what format it's in? I.E html, pdf, Word doc, etc. The GMail Inbox Feed api isn't good enough and before I start trying to build an IMAP solution that pulls in PDF/Word doc converters, I thought it'd be good to ask here.

• Kohana -- Command Line

  - by swt83

  I'm trying to "faux-fork" a process (an email being sent via SMTP) in my web application, and the application is built on Kohana. $command = 'test/email'; exec('php index.php '.$command.' > /dev/null/ &', $errors, $response); I'm getting an error -- Notice: Undefined index: SERVER_NAME When I look into Kohana's index.php file, I see that it is looking for a variable named SERVER_NAME, but I guess it is coming up NULL because Kohana couldn't detect this value and set it prior to run. Any ideas how to get Kohana to run via command line?

• Browser loading strategy, <head>...<body>

  - by Bin Chen

  I am inspecting some interesting behaviors of browser, I don't know it's in standard or not. If I put everythin inside <head></head>, the browser will only begin to render the page after all the resouces in head is retrieved. So I am thinking that put as little as possible things into head is one of the important website optimization techniques, is it right? My question is: If I put script/css in body or other parts of the html, how can I know that script has been loaded successfully so that I will not be calling a undefined function?

• 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 });

• 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?

• Javascript / jQuery Exec turns up Null

  - by Matrym

  How do I skip over this next line if it turns out to be null? Currently, it (sometimes) "breaks" and prevents the script from continuing. var title = (/(.*?)<\/title/m).exec(response)[1]; $.get(url, function(response){ var title = (/<title>(.*?)<\/title>/m).exec(response)[1]; if (title == null || title == undefined){ return false; } var words = title.split(' '); $.each(words, function(index, value){ $link.highlight(value + " "); $link.highlight(" " + value); }); });

  I'm not sure how to do this without getting an error. Here is a simplified example of my problem. Say I have this data frame DF a b c d 1 2 3 4 2 3 4 5 3 4 5 6 Then I have a variable x <- min(c(1,2,3)) Now I want do do the following y <- DF[a == x] But when I try to refer to some variable like "x" I get an error because R is looking for a column "x" in my data frame.

• How do I set a property to the output of a command in msbuild/xbuild

  - by Nils

  In msbuild/xbuild I'd like to have a "libPath" property which can be ovveridden on the commandline using /p:libpath="/path/to/all/libs". But when this property is undefined I want to call pkg-config --retrieve-Path somePackage to get the current systems path. I thought like here I need the output of a command to be stored in a Property. The command always returns one line of output. I have tryied something like <PropertyGroup> <LibPath /> </PropertyGroup> <Task ....> <Exec Command="pkg-config --retrieve-Path somePackage" Condition="$(LibPath)' == ''"> <OutputTaskParameter="output" PropertyName="LibPath" /> </Exec> </Task> But that didn't work.

• Changing the onClick area when adding an event

  - by Josh Breslow

  Is there anyway to change what a user clicks on to add an event? Right now the entire day is clickable. This becomes an issue when the user needs to put focus back on that window, requiring a mouse click. If they click on the calendar, which takes up most of the page, then they launch the "Add Event" function. Is there a way to have a Plus sign (+), or whatever symbol in each day that when clicked, launches the "Add Event" function? Or... Is there a way to have a button across the top that said, "Add Event"?

• How can I find out if an data- attribute is set to an empty value?

  - by Stephan Wagner

  Is there a way to find out if an data- attribute is set to an empty value or if it is not set at all? See this fiddle example (Check the console when clicking on the elements): http://jsfiddle.net/StephanWagner/yy8qvwfp/ <div onclick="console.log($(this).attr('data-test'))">undefined</div> <div data-test="" onclick="console.log($(this).attr('data-test'))">empty</div> <!-- this one will also return an empty value --> <div data-test onclick="console.log($(this).attr('data-test'))">null</div> <div data-test="value" onclick="console.log($(this).attr('data-test'))">value</div> Im having the issue with the third example. I need to know if the attribute actually is set to an empty value or if it is not set at all. Is that actually possible? EDIT: The reason I'm asking is that I'm updating content with the attributes value, so data-test="" should update the content to an empty value, but data-test should do nothing at all

• How are Flash library symbols constructed? Why are width/height already available in constructor?

  - by Triynko

  Suppose I draw a square on the stage, convert it to a symbol, export it for ActionScript with a classname of "MySquare" (and of course a base class of MovieClip). How is it that in the MySquare constructor, the width and height of this MovieClip are already available? In fact, any named instances in the clip are also available. I'm confused about how the Flash player seems to be able to pre-construct my movie clip by populating its properties and child clips before my constructor for the class ever runs. I thought that it would have to first construct the clip, calling my constructor code, and then construct and add any children, but obviously the player is doing something special for clips designed in the Flash authoring environment.

• Ruby on Rails: Unit Testing non activerecord models and still load fixtures

  - by Vaibhav Gumashta

  I may be missing something but I am stuck in this scenario: I have a non activerecord model, which I want to test. I have derived its test case class from: Test::Unit::TestCase. However, the test case class for the model, uses within itself, other activerecord model classes and I want to load fixtures for them. My problem is that the fixtures class method is available only when I subclass the test case class from ActiveSupport::TestCase (it is defined within ActiveRecord::TestFixtures which gets included in ActiveSupport::TestCase). Any help, coz running the tests gives me the error: undefined method "fixtures" (which is understandable) and in case I derive my test case class from ActiveSupport::TestCase it complains that there is no corresponding DB table. Also, I don't want to create a dummy table for backing my model class. Thanks a ton!

• jQuery DOM append losing markup

  - by Raj

  This is related to an earlier question. I try to append HTML DOM returned in an AJAX response to an existing DIV. I see all the text, but it seems all markup such as bold, italic, etc is lost. My AJAX (XML) data is like so: <event source="foo"> <contents> <h1>This is an event</h1> This is the body of the event </contents> </event> My jQuery code does this: $("#eventDiv").append( jData.find("contents").contents().clone() ); Attempting to do .html() on the cloned contents throws an exception: TypeError: Cannot call method 'replace' of undefined. I am a little surprised that it is so excruciatingly hard to do this with jQuery. Am I doing something too far off the track?

• Rails - Trying to query from a date range...everything from today

  - by ChrisWesAllen

  I'm trying to figure the best way to query a date range from rails...I looked around on Google but am unsure about how to use this syntax. I have a Model that has various events and I like to add to my find condition a caveat that should only show events where the field :st_date is today or later, in effect only show me data that is current, nothing that happened before today. I ran into a problem because I have no end date to stop the query, I want to query everything from today to next month. I was thinking something like @events = Event.find(:all, :conditions => ["start_date between ? and ?", date.Today, date.next_month.beginning_of_month]) but I get the error undefined local variable or method `date'...... Do I need do anything particular to use the Date class? Or is there something wrong with my query syntax? I would really appreciate any help.

• passing self data into a recursive function

  - by user272689

  I'm trying to set a function to do something like this def __binaryTreeInsert(self, toInsert, currentNode=getRoot(), parentNode=None): where current node starts as root, and then we change it to a different node in the method and recursivly call it again. However, i cannot get the 'currentNode=getRoot()' to work. If i try calling the funcion getRoot() (as above) it says im not giving it all the required variables, but if i try to call self.getRoot() it complains that self is an undefined variable. Is there a way i can do this without having to specify the root while calling this method?

• Linker Error: iPhone Unit Test Bundle referencing App classes

  - by ohhorob

  Starting with an app already in development, I have carried out the instructions in the iPhone Development Guide – Unit Testing Applications I can successfully include and use my App's classes in Application-style tests that run on the device, and output their results to the console. If I add the following line of code: STAssertTrue([viewController isKindOfClass:[LoginViewController class]], @"Top view controller is not LoginViewController"); The following build error is generated: Undefined symbols: "_OBJC_CLASS_$_LoginViewController", referenced from: __objc_classrefs__DATA@0 in LoginViewTest.o ld: symbol(s) not found collect2: ld returned 1 exit status I can provide more configuration information for the project and the Testing target, but the setup works file without the [LoginViewController class] line in the test source. Without that line, I can reference the class, use it's properties and send it messages successfully. Is there a linking build setting, or bundle loading option that is required when attempting to use an App class in this fashion? Or should I find another type of test to confirm that the class of an object is the expected one?

• Calling local function with Jquery

  I have a JQuery function as followss: (function($){ $.fn.autoSuggest = function(data, options) { function add_selected_item(data, num){ (function($){ $.fn.autoSuggest = function(data, options) { alert(data); } }); } }); If I wanted to call the local add_selected_item() function from outside this function, how would I do it? I've tried doing: $.autoSuggest.add_selected_item(data, opt); But am getting an $.autoSuggest is undefined. Still learning the ropes with JQUery. I am not sure exactly how this can be accomplished, if at all. Thanks!
