  • Test Ruby-on-Rails controller with RSpec and different route name

    - by jhwist
    I have a Rails model named Xpmodule with a corresponding controller XpmoduleController. class XpmoduleController < ApplicationController def index @xpmodule = Xpmodule.find(params[:module_id]) end def subscribe flash[:notice] = "You are now subscribed to #{params[:subscription][:title]}" redirect_to :action => :index end end The original intent was to name the model Module which for obvious reasons doesn't work. However I still want to have the URLs look like /module/4711/ therefore I added this to my routes.rb: map.connect '/module/:module_id', :controller => 'xpmodule', :action => 'index' map.connect '/module/:module_id/subscribe', :controller => 'xpmodule', :action => 'subscribe' Now I want to test this controller with Rspec: describe XpmoduleController do fixtures :xpmodules context "index" do it "should assign the current xpmodule" do xpm = mock_model(Xpmodule) Xpmodule.should_receive(:find).and_return(xpm) get "index" assigns[:xpmodule].should be_an_instance_of(Xpmodule) end end end for which I get No route matches {:action=>"index", :controller=>"xpmodule"}. Which of course is sort-of right, but I don't want to add this route just for testing purposes. Is there a way to tell Rspec to call a different URL in get?

  • How do I test OpenCL on GPU when logged in remotely on Mac?

    - by Christopher Bruns
    My OpenCL program can find the GPU device when I am logged in at the console, but not when I am logged in remotely with ssh. Further, if I run the program as root in the ssh session, the program can find the GPU. The computer is a Snow Leopard Mac with a GeForce 9400 GPU. If I run the program (see below) from the console or as root, the output is as follows (notice the "GeForce 9400" line): 2 devices found Device #0 name = GeForce 9400 Device #1 name = Intel(R) Core(TM)2 Duo CPU P8700 @ 2.53GHz but if it is just me, over ssh, there is no GeForce 9400 entry: 1 devices found Device #0 name = Intel(R) Core(TM)2 Duo CPU P8700 @ 2.53GHz I would like to test my code on the GPU without having to be root. Is that possible? Simplified GPU finding program below: #include <stdio.h> #include <OpenCL/opencl.h> int main(int argc, char** argv) { char dname[500]; size_t namesize; cl_device_id devices[10]; cl_uint num_devices; int d; clGetDeviceIDs(0, CL_DEVICE_TYPE_ALL, 10, devices, &num_devices); printf("%d devices found\n", num_devices); for (d = 0; d < num_devices; ++d) { clGetDeviceInfo(devices[d], CL_DEVICE_NAME, 500, dname, &namesize); printf("Device #%d name = %s\n", d, dname); } return 0; } EDIT: I found essentially the same question being asked on nvidia's forums. Unfortunately, the only answer was of the form "this is the wrong forum".

  • identation control while developing a small python like language

    - by sap
    Hello, Im developing a small python like language using flex, byacc (for lexical and parsing) and C++, but i have a few questions regarding scope control. just as python it uses white spaces (or tabs) for identation, not only that but i want to implement index breaking like for instance if you type "break 2" inside a while loop thats inside another while loop it would not only break from the last one but from the first loop as well (hence the number 2 after break) and so on. example: while 1 while 1 break 2 end end #after break 2 it would jump right here but since i dont have an "anti" tab character to check when a scope ends (like C for example i would just use the '}' char) i was wondering if this method would the the best: i would define a global variable, like "int tabIndex" on my yacc file that i would access in my lex file using extern. then everytime i find a tab character on my lex file i would increment that variable by 1. when parsing on my yacc file if i find a "break" keyword i would decrement by the amount typed after it from the tabIndex variable, and when i reach and EOF after compiling and i get a tabIndex != 0 i would output compilation error. now the problem is, whats the best way to see if the identation got reduced, should i read \b (backspace) chars from lex and then reduce the tabIndex variable (when the user doesnt use break)? another method to achieve this? also just another small question, i want every executable to have its starting point on the function called start() should i hardcode this onto my yacc file? sorry for the long question any help is greatly appretiated. also if someone can provide an yacc file for python would be nice as a guideline (tried looking on google and had no luck). thanks in advance.

  • Does jQuery strip some html elements from a string when using .html()?

    - by Nic Hubbard
    I have a var that contains a full html page, including the head, html, body, etc. When I pass that string into the .html() function, jQuery strips out all those elements, such as body, html, head, etc, which I don't want. My data var contains: <html> <head> <title>Untitled Document</title> </head> <body> </body> </html> // data is a full html document string data = $('<div/>').html(data); // jQuery stips my document string! alert(data.find('head').html()); I am needing to manipulate a full html page string, so that I can return what is in the element. I would like to do this with jQuery, but it seems all of the methods, append(), prepend() and html() all try to convert the string to dom elements, which remove all the other parts of a full html page. Is there another way that I could do this? I would be fine using another method. My final goal is to find certain elements inside my string, so I figured jQuery would be best, since I am so used to it. But, if it is going to trim and remove parts of my string, I am going to have to look for another method. Ideas?

  • Zend Framework: How to start PHPUnit testing Forms?

    - by Andrew
    I am having trouble getting my filters/validators to work correctly on my form, so I want to create a Unit test to verify that the data I am submitting to my form is being filtered and validated correctly. I started by auto-generating a PHPUnit test in Zend Studio, which gives me this: <?php require_once 'PHPUnit/Framework/TestCase.php'; /** * Form_Event test case. */ class Form_EventTest extends PHPUnit_Framework_TestCase { /** * @var Form_Event */ private $Form_Event; /** * Prepares the environment before running a test. */ protected function setUp () { parent::setUp(); // TODO Auto-generated Form_EventTest::setUp() $this->Form_Event = new Form_Event(/* parameters */); } /** * Cleans up the environment after running a test. */ protected function tearDown () { // TODO Auto-generated Form_EventTest::tearDown() $this->Form_Event = null; parent::tearDown(); } /** * Constructs the test case. */ public function __construct () { // TODO Auto-generated constructor } /** * Tests Form_Event->init() */ public function testInit () { // TODO Auto-generated Form_EventTest->testInit() $this->markTestIncomplete( "init test not implemented"); $this->Form_Event->init(/* parameters */); } /** * Tests Form_Event->getFormattedMessages() */ public function testGetFormattedMessages () { // TODO Auto-generated Form_EventTest->testGetFormattedMessages() $this->markTestIncomplete( "getFormattedMessages test not implemented"); $this->Form_Event->getFormattedMessages(/* parameters */); } } so then I open up terminal, navigate to the directory, and try to run the test: $ cd my_app/tests/unit/application/forms $ phpunit EventTest.php Fatal error: Class 'Form_Event' not found in .../tests/unit/application/forms/EventTest.php on line 19 So then I add a require_once at the top to include my Form class and try it again. Now it says it can't find another class. I include that one and try it again. Then it says it can't find another class, and another class, and so on. I have all of these dependencies on all these other Zend_Form classes. What should I do? How should I go about testing my Form to make sure my Validators and Filters are being attached correctly, and that it's doing what I expect it to do. Or am I thinking about this the wrong way?

  • Get coordinates of google maps markers

    - by App_beginner
    I am creating a databse containing the names and coordinates of all bus stops in my local area. I have all the names stored in my database, and now I need to add the coordinates. I am trying to get these of a website that contains them all as placemarks on a google map. It seems to me like they are being generated from a local server, and then added to the map. However I am unable to find exactly where the server is queried for the coordinates. I am hoping to collect these coordinates through the use of a screen scraper. However unless I am able to find where in the source code the coordinates are created this seems to be impossible. I can of course search and collect all these placemarks manually, but that will be very time consuming. So I am hoping that someone in here can help me. This is the website I am trying to scrape. The placemarks are marked by the blue bus sign: http://reiseplanlegger.skyss.no/scripts/travelmagic/TravelMagicWE.dll/?from=Brimnes+ferjekai+%28Eidfjord%29&to= You can also get the coordinates of a single placemark by writing the name of the stop in the search field and pushing the "Vis i kart" button. I hope someone can help me with this.

  • How can I write good "research code"?

    - by John
    "Research code" is often held up as a paragon of what not to do when writing software. Certainly, the kind of code that often results from trying to solve a research problem can end up being poorly-designed, difficult to debug, etc. But my question is this: does research code have to be this way? Is it possible to write good research code? Is the only approach to consider the first version a poorly-written prototype to be discarded in favour of the better-designed second version? Software engineering has all sorts of best practices about how to design and write good code, but I don't usually find this relevant when you don't have a good idea ahead of time what the final system will look like. The final system is likely to be a result of what did or didn't work along the way, and the only way to determine what does or doesn't work is to write the code first. As you find things that don't work, you change what the final system looks like, moving further away from your original design (assuming you had one). I'd be interested in any personal experience with these issues, as well as any books or other resources anyone can point me to.

  • Create combined client side and server side validation in Symfony2

    - by ausi
    I think it would be very useful to create client side form validation up on the symfony2 Form and Validator components. The best way to do this would be to pass the validation constraints to the form view. With that information it would be possible to make a template that renders a form field to something like this: <div> <label for="form_email">E-Mail</label> <input id="form_email" type="text" name="form[email]" value="" data-validation-constraints='["NotBlank":{},"MinLength":{"limit":6}]' /> </div> The JavaScript part then would be to find all <input> elements that have the data-validation-constraints attribute and create the correct validation for them. To pass the validation constraints to the form view i thought the best way would be to create a form type extension. That's the point of my Question: Is this the correct way? And how is this possible? At the Moment my form type extension looks like this: use Symfony\Component\Form\FormInterface; use Symfony\Component\Form\FormView; use Symfony\Component\Form\FormBuilder; class FieldTypeExtension extends \Symfony\Component\Form\AbstractTypeExtension{ public function getExtendedType(){ return 'field'; } public function buildView(FormView $view, FormInterface $form) { // at this point i didn't find a way to get the // validation constraints out of the $form // the `getAllValidationConstraints` here is just an example $view->set('validation_constraints', $form->getAllValidationConstraints()); } } How can i get all validation constraints applied to one form field out of the FormInterface object?

  • Custom Django admin URL + changelist view for custom list filter by Tags

    - by Botondus
    In django admin I wanted to set up a custom filter by tags (tags are introduced with django-tagging) I've made the ModelAdmin for this and it used to work fine, by appending custom urlconf and modifying the changelist view. It should work with URLs like: http://127.0.0.1:8000/admin/reviews/review/only-tagged-vista/ But now I get 'invalid literal for int() with base 10: 'only-tagged-vista', error which means it keeps matching the review edit page instead of the custom filter page, and I cannot figure out why since it used to work and I can't find what change might have affected this. Any help appreciated. Relevant code: class ReviewAdmin(VersionAdmin): def changelist_view(self, request, extra_context=None, **kwargs): from django.contrib.admin.views.main import ChangeList cl = ChangeList(request, self.model, list(self.list_display), self.list_display_links, self.list_filter, self.date_hierarchy, self.search_fields, self.list_select_related, self.list_per_page, self.list_editable, self) cl.formset = None if extra_context is None: extra_context = {} if kwargs.get('only_tagged'): tag = kwargs.get('tag') cl.result_list = cl.result_list.filter(tags__icontains=tag) extra_context['extra_filter'] = "Only tagged %s" % tag extra_context['cl'] = cl return super(ReviewAdmin, self).changelist_view(request, extra_context=extra_context) def get_urls(self): from django.conf.urls.defaults import patterns, url urls = super(ReviewAdmin, self).get_urls() def wrap(view): def wrapper(*args, **kwargs): return self.admin_site.admin_view(view)(*args, **kwargs) return update_wrapper(wrapper, view) info = self.model._meta.app_label, self.model._meta.module_name my_urls = patterns('', # make edit work from tagged filter list view # redirect to normal edit view url(r'^only-tagged-\w+/(?P<id>.+)/$', redirect_to, {'url': "/admin/"+self.model._meta.app_label+"/"+self.model._meta.module_name+"/%(id)s"} ), # tagged filter list view url(r'^only-tagged-(P<tag>\w+)/$', self.admin_site.admin_view(self.changelist_view), {'only_tagged':True}, name="changelist_view"), ) return my_urls + urls Edit: Original issue fixed. I now receive 'Cannot filter a query once a slice has been taken.' for line: cl.result_list = cl.result_list.filter(tags__icontains=tag) I'm not sure where this result list is sliced, before tag filter is applied. Edit2: It's because of the self.list_per_page in ChangeList declaration. However didn't find a proper solution yet. Temp fix: if kwargs.get('only_tagged'): list_per_page = 1000000 else: list_per_page = self.list_per_page cl = ChangeList(request, self.model, list(self.list_display), self.list_display_links, self.list_filter, self.date_hierarchy, self.search_fields, self.list_select_related, list_per_page, self.list_editable, self)

  • Windows-Mobile Directshow: Specifying bitrate/quality of a WMV video capture

    - by Landstander
    Hi- I'm stumped on this, and I'm really hoping someone could point me in the right direction. I'm currently capturing video in Windows Mobile and encoding it using the WMV 9 DMO (CLSID_CWMV9EncMediaObject). That all works well enough, but the output video's bitrate is too high, resulting in a video file that's much too large for my needs. Ultimately, my goal is to mimic the video settings that Microsoft's Camera Capture Dialog outputs in the "messaging" quality mode (64kbps) from my C++ code. Currently, my code's outputting a WMV file with a bitrate of 352kbps. The only example I could find of specifying the capture bitrate with a WMV9 DMO was this. The idea in that code was basically to use a propertybag to write a bitrate to a property of the DMO. Update: In windows mobile, the closest codec property I can find that seems to equate to the bitrate is "g_wszWMVCVBRQuality". Microsoft's documentation of this property is extremely confusing to me: It basically seems to say that a higher number equates to a higher quality, but it gives absolutely no explanation of the specifics for each number. When I attempt to set this property to value like "1" via a propertybag for the WMV9 DMO, I run into a -2147467259 (unknown) error. To summarize: What is the basic strategy to specify the bitrate/quality of a video being captured via directshow (wmv9) on a windows mobile platform? I've heard (or wondered about) the following methods: Use the propertybag to change the encoder DMO's property that corresponds to bitrate/quality (currently failing) Create your own custom transcoder/encoder to specify it. This seems unnecessary since the WMV encoder works well enough- it's just at too high a bitrate. The VIDEOINFOHEADER has a bitrate property, but I suspect that specifying new settings here will do nothing to alter the actual encoding process since I wouldn't think file attributes would come into play until after the encoding. Any suggestions? PS: I would post specific source code, but at this point it may confuse more than it helps since I'm floundering so much on how to do this. At this point, I'm just trying to validate the general strategy. THANKS!

  • Using Traveling Salesman Solver to Decide Hamiltonian Path

    - by Firas Assaad
    This is for a project where I'm asked to implement a heuristic for the traveling salesman optimization problem and also the Hamiltonian path or cycle decision problem. I don't need help with the implementation itself, but have a question on the direction I'm going in. I already have a TSP heuristic based on a genetic algorithm: it assumes a complete graph, starts with a set of random solutions as a population, and works to improve the population for a number of generations. Can I also use it to solve the Hamiltonian path or cycle problems? Instead of optimizing to get the shortest path, I just want to check if there is a path. Now any complete graph will have a Hamiltonian path in it, so the TSP heuristic would have to be extended to any graph. This could be done by setting the edges to some infinity value if there is no path between two cities, and returning the first path that is a valid Hamiltonian path. Is that the right way to approach it? Or should I use a different heuristic for Hamiltonian path? My main concern is whether it's a viable approach since I can be somewhat sure that TSP optimization works (because you start with solutions and improve them) but not if a Hamiltonian path decider would find any path in a fixed number of generations. I assume the best approach would be to test it myself, but I'm constrained by time and thought I'd ask before going down this route... (I could find a different heuristic for Hamiltonian path instead)

  • Can a call to WaitHandle.SignalAndWait be ignored for performance profiling purposes?

    - by Dan Tao
    I just downloaded the trial version of ANTS Performance Profiler from Red Gate and am investigating some of my team's code. Immediately I notice that there's a particular section of code that ANTS is reporting as eating up to 99% CPU time. I am completely unfamiliar with ANTS or performance profiling in general (that is, aside from self-profiling using what I'm sure are extremely crude and frowned-upon methods such as double timeToComplete = (endTime - startTime).TotalSeconds), so I'm still fiddling around with the application and figuring out how it's used. But I did call the developer responsible for the code in question and his immediate reaction was "Yeah, that doesn't surprise me that it says that; but that code calls SignalAndWait [which I could see for myself, thanks to ANTS], which doesn't use any CPU, it just sits there waiting for something to do." He advised me to simply ignore that code and look for anything ELSE I could find. My question: is it true that SignalAndWait requires NO CPU overhead (and if so, how is this possible?), and is it reasonable that a performance profiler would view it as taking up 99% CPU time? I find this particularly curious because, if it's at 99%, that would suggest that our application is often idle, wouldn't it? And yet its performance has become rather sluggish lately. Like I said, I really am just a beginner when it comes to this tool, and I don't know anything about the WaitHandle class. So ANY information to help me to understand what's going on here would be appreciated.

  • What's the strangest corner case you've seen in C# or .NET?

    - by Jon Skeet
    I collect a few corner cases and brain teasers and would always like to hear more. The page only really covers C# language bits and bobs, but I also find core .NET things interesting too. For example, here's one which isn't on the page, but which I find incredible: string x = new string(new char[0]); string y = new string(new char[0]); Console.WriteLine(object.ReferenceEquals(x, y)); I'd expect that to print False - after all, "new" (with a reference type) always creates a new object, doesn't it? The specs for both C# and the CLI indicate that it should. Well, not in this particular case. It prints True, and has done on every version of the framework I've tested it with. (I haven't tried it on Mono, admittedly...) Just to be clear, this is only an example of the kind of thing I'm looking for - I wasn't particularly looking for discussion/explanation of this oddity. (It's not the same as normal string interning; in particular, string interning doesn't normally happen when a constructor is called.) I was really asking for similar odd behaviour. Any other gems lurking out there?

  • Using jQuery to grab the content from CKEditor's iframe

    - by miCRoSCoPiC_eaRthLinG
    Hey guys, I have this custom written CMS that uses CKEditor *(FCKEditor v3) for editing content. Along with that I'm using the jQuery Validation plugin to check all fields for error prior to ajax-based submission. For passing on the data to the PHP backend, I'm using the serialize() function. Problem is, serialize manages to grab all other fields correctly, except for the actual content typed in CKEditor. Like every other WYSIWYG editor, this one too overlays an iframe over an existing textbox. And serialize ignores the iframe and looks only into the textbox for content... which of course, it doesn't find - thus returning a blank content body. My approach to this is to create a hook onto the onchange event of CKEditor and concurrently update the textbox (CKEDITOR.instances.[textboxname].getData() returns the content) or some other hidden field with any changes made in the editor. However, since CKEditor is still in it's beta stage and severely lacks documentation, I cannot seem to find a suitable API call that'll enable me to do so. Does anyone have any idea on how to go about this? Or maybe suggest even a better method?

  • Displaying Many-To-Many Database relationship in VB.NET 2008 with DataGrid, MS SQL 2008

    - by user337501
    Computer bombed while posting this, couldnt find a duplicate question but if there is one, forgive me. So, I've run into a wall. And rather than use a ladder to avoid it, I'd like go through it. I'm setting up what I can best describe as a many-to-many relationship in a database. To examplify, imagine I have three primary tables: Items, Categories, Sections(nevermind the potential redundancy) Then I have another table, Properties. Items, Categories, and Sections can be associated with many properties. A single property can be associated with one, all, or none of the other tables. The best way I can figure to do this is to have join tables make the relationship. i.e. tblItems----(Foreign Key)----tblItems_To_Properties----(Foreign Key)----tblProperties In this example, tblItems simply has an "ItemID" Primary Key. tblItems_To_Properties has its own Primary Key(tblItems_To_PropertiesID), a Foreign Key to the Item(ItemID) and a Foreign key to the Property(PropertyID). The Properties table simply has its primary key(PropertyID) I hope this example isnt too confusing...if I have to I can find a way to put a diagram up or something. My problem is, I want to display this in a DataGrid using the Master-Detail method(DevExpress GridControl). I use the tblItems as a test, and I can see the Items in the parent view, but in the child view I see(understandably) the join table and that is it. My goal is to make it so the Grid ignores the join table and shows the Properties table as the only child. Any help on this method or insight into another solution would be muuuuuuuch appreciat

  • How do I pass a callback function to sqlite3_exec on iOS 5.1?

    - by John Doh
    I am new to both xcode/iOS/Objective-C and sqlite. I am trying to teach myself the basics - and I would like to use the sqlite3 wrapper "sqlite3_exec" for a select query. For some reason, I can't find a simple example anywhere of someone doing this. Basically, the method has a parameter (the third one) for a callback function: int sqlite3_exec( sqlite3*, /* An open database */ const char *sql, /* SQL to be evaluated */ int (*callback)(void*,int,char**,char**), /* Callback function */ void *, /* 1st argument to callback */ char **errmsg /* Error msg written here */ ); That's fine. I'm no stranger to callbacks. However, I just can't seem to get the syntax down right. I took over one of the view controllers in my iPad (iOS 5.1) xcode (4.3) project, and made the changes shown below: #import "SecondViewController.h" #import "sqlite3.h" #import "AppState.h" @interface SecondViewController () @end @implementation SecondViewController - (int)myCallback:(void *)a_parm argc:(int)argc argv:(char **)argv column:(char **)column { return 0; } - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. //grab questionnaire names char *sql = "select * from QST2Main order by [Name]"; char *err = nil; sqlite3 *db = [[AppState sharedManager] getgCn]; sqlite3_exec(db, sql, myCallback, nil, &err); } Essentially, I want to run a query when this view first loads, to store some data for later use. But, XCode doesn't like the "myCallback" usage at the bottom there. It says: Undeclared Use of Identifier 'myCallback.' That method is declared in the header file, and I've even tried making it static. Nothing seems to make this error go away. I know I must be doing something fundamentally wrong here, but for the life of me I can't figure out what - I can't even find other code samples in this area that could help me figure out what I'm missing. Many thanks!

  • Building error in Eclipse with build.xml

    I am working on a Java project with Eclipse. This project requires a second project (not mine), named sams in its build-path. The sams is provided with a build.xml file and it should generate some code using Apache CXF when building it. When I use Apache ANT on Eclipse and run the cxf.generated command from its build file I get the following error: Buildfile: C:\Docs\ZacRocha\Desktop\sams\build.xml cxf.generated: [echo] Generating code using Apache CXF wsdl2java...

Can someone tell me where exactly the problem may be? Thanks in advance!

  • Help matching fields between two classes

    - by Michael
    I'm not too experienced with Java yet, and I'm hoping someone can steer me in the right direction because right now I feel like I'm just beating my head against a wall... The first class is called MeasuredParams, and it's got 40+ numeric fields (height, weight, waistSize, wristSize - some int, but mostly double). The second class is a statistical classifier called Classifier. It's been trained on a subset of the MeasuredParams fields. The names of the fields that the Classifier has been trained on is stored, in order, in an array called reqdFields. What I need to do is load a new array, toClassify, with the values stored in the fields from MeasuredParams that match the field list (including order) found in reqdFields. I can make any changes necessary to the MeasuredParams class, but I'm stuck with Classifier as it is. My brute-force approach was to get rid of the fields in MeasuredParams and use an arrayList instead, and store the field names in an Enum object to act as an index pointer. Then loop through the reqdFields list, one element at a time, and find the matching name in the Enum object to find the correct position in the arrayList. Load the value stored at that positon into toClassify, and then continue on to the next element in reqdFields. I'm not sure how exactly I would search through the Enum object - it would be a lot easier if the field names were stored in a second arrayList. But then the index positions between the two would have to stay matched, and I'm back to using an Enum. I think. I've been running around in circles all afternoon, and I keep thinking there must be an easier way of doing it. I'm just stuck right now and can't see past what I've started. Any help would be GREATLY appreciated. Thanks so much! Michael

  • How to determine if "html" or "body" scrolls the window.

    - by David Murdoch
    The code below is used to find the element that can be scrolled (body or html) via javascript. var scrollElement = (function (tags) { var el, $el, init; // iterate through the tags... while (el = tags.pop()) { $el = $(el); // if the scrollTop value is already > 0 then this element will work if ( $el.scrollTop() > 0){ return $el; } // if scrollTop is 0 try to scroll. else if($el.scrollTop( 1 ).scrollTop() > 0) { // if that worked reset the scroll top and return the element return $el.scrollTop(0); } } return $(); } (["html", "body"])); // do stuff with scrollElement...like: // scrollElement.animate({"scrollTop":target.offset().top},1000); This code works perfectly when the height of the document is greater than the height of the window. However, when the height of the document is the same or less than the window the method above will not work because scrollTop() will always be equal to 0. This becomes a problem if the DOM is updated and the height of the document grows beyond the height of the window after the code runs. Also, I generally don't wait until document.ready to set up my javascript handlers (this generally works). I could append a tall div to the body temporarily to force the method above to work BUT that would required the document to be ready in IE (you can't add a node to the body element before the tag is closed). For more reading on the document.ready "anti-pattern" topic read this. So, I'd love to find a solution that finds the scrollable element even when the document is short. Any ideas?

  • jQuery: script remember values between times it is triggered?

    - by Marius
    Hello there, I am writing an ajax script in jQuery. The script gets new or previous page from a php documents that returns HTML. If, located on page 1, I click next, the script IS able to find the next page number (page2), but when I click it AGAIN, the script again has to be able to find the next page number (page3) and at the minute it doesnt. I was wondering how I can save a variable between time a script is triggered, so that I can just + 1 to each time somebody clicks "next", and -1 when somebody clicks "previous". This is my code: $('.buttonNeste').click(function(event){ event.preventDefault(); if (page == null || id == null ) { var page = parseInt($(this).closest('.paginationFullWidth').attr('id')) + 1; var id = $(this).closest('.paginationFullWidth').siblings('.jtextfill').children('h1').attr('id'); } else { var page = page + 1; } var target = $(this); $.post( 'http://www.example.com/controllers/foo.php', { 'page': ( page ), 'id': id }, function(data) { $(target).closest('.paginationFullWidth').siblings('.commentsContainer').html(data); }); }); Thank you for your time. Kind regards, Marius

  • Eclipse / Aptana File Sync Solutions

    - by Brad
    Our development team uses Eclipse + Aptana to do their web development work. Currently, most of them are mapping their Eclipse projects directly to the web server. I'd rather them create a local project and use that to sync to the web server project directory they are working on. The issue is that there aren't any good solutions which is just appalling given the popularity of the two. The FileSync plugin for Eclipse is only one-way. Meaning if another developer makes a change to the file on the server, another dev isn't even notified and could overwrite the change. The File Transfer option in Aptana 2.0 doesn't support any sort of Sync, just manually uploading/downloading files. The Sync option in Aptana 1.5.1 doesn't allow you to merge files when they are different. You can only update one or the other. It does however allow you to view a diff (but only if you right click and select) and in that diff you can't make any changes. I did find a way to allow files to be uploaded to their Sync repositories in Aptana using Eclipse Monkey. However it doesn't work if a user saves multiple files at once, 'Save All', again it doesn't work. And additionally, there is no notification if a user opens a local file that has an updated copy on the server. I tried to add one using Eclipse Monkey but I couldn't find any sort of listener in the Eclipse API to do it and any Eclipse Monkey documentation is far and few between. My only solution at this point is just to let them continue to map directly to the server or ask them to do a manual download before they do any work (but again what if someone uploads a change right after they do that). Anyone have any ideas?

  • MKAnnotationView is not added for some annotations

    - by Dave
    I find that MKMapView has to be re-centered to a significant distance away from an existing map center to be able to add more annotations to the map and DISPLAY them. Is this a bug in SDK 3.2? I have looked literally EVERYWHERE and can't find a way to refresh the map view without having to zoom in or zoom out or move the map view. Why?? I don't mind if the solution involves doing a bunch of custom delegates and notifications. I just NEED this so bad. Basically, I am adding pins (annotations) to a map view when performing a search for businesses. I remove existing annotations on every search. So the annotations are added to the map on every search. If I search twice with the same map view, I see the results loading but the map view is empty. The pins will appear if i move/resize/zoom in. Anybody seen this? any help is appreciated.
