  • jquery "this" binding issue on event handler

    - by clyfe
    In jquery an event hadler's binding is the event generating DOM element (this points to the dom element). In prototype to change the binding of an event handler one can use the bindAsEventListener function; How can I access both the instance and the DOM element from a event handler? Similar to http://stackoverflow.com/questions/117361/how-can-i-bind-an-event-handler-to-an-instance-in-jquery function Car(){ this.km = 0; $("#sprint").click(this.drive); //setup event handler } // event handler // in it I need to access both the clicked element // and the binding object (instance of car) Car.prototype.drive = function(){ this.km += 10; // i'd like to access the binding (but jq changes it) this.css({ left: this.km }); // also the element // NOTE that is inside this function I want to access them not elsewhere } var car = new Car();

  • Non-Dom Element Event Binding with jQuery

    Yesterday I had a short discussion with Dave Reed on Twitter regarding setting up fake events on objects that are hookable. jQuery makes it real easy to bind events on DOM elements and with a little bit of extra work (that I didnt know about) you can also set up binding to non-DOM element event bindings. Assume for a second that you have a simple JavaScript object like this: var item = { sku: "wwhelp" , foo: function() { alert('orginal foo function'); } }; and...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Get the onended event for an AudioBuffer in HTML5/Chrome

    - by Matthew James Davis
    So I am playing audio file in Chrome and I want to detect when playing has ended so I can delete references to it. Here is my code var source = context.createBufferSource(); source.buffer = sound.buffer; source.loop = sound.loop; source.onended = function() { delete playingSounds[soundName]; } source.connect(mainNode); source.start(0, sound.start, sound.length); however, the event handler doesn't fire. Is this not yet supported as described by the W3 specification? Or am I doing something wrong?

  • Reflections on GiveCamp

    - by Reed
    I participated in the Seattle GiveCamp over the weekend, and am entirely impressed.  GiveCamp is a great event – I especially like how rewarding it is for everybody involved.  I strongly encourage any and all developers to watch for future GiveCamp events, and consider participating, for many reasons… GiveCamp provides real value to organizations that truly need help.  The Seattle event alone succeeded in helping sixteen non-profit organizations in many different ways.  The projects involved varied dramatically, including website redesigns, SEO, reworking data management workflows, and even game development.  Many non-profits have a strong need for good, quality technical help.  However, nearly every non-profit organization has an incredibly limited budget.  GiveCamp is a way to really give back, and provide incredibly valuable help to organizations that truly benefit. My experience has shown many developers to be incredibly generous – this is a chance to dedicate your energy to helping others in a way that really takes advantage of your expertise.  Your time as a developer is incredibly valuable, and this puts something of incredible value directly into the hands of places its needed. First, and foremost, GiveCamp is about providing technical help to non-profit organizations in need. GiveCamp can make you a better developer.  This is a fantastic opportunity for us, as developers, to work with new people, in a new setting.  The incredibly short time frame (one weekend for a deliverable project) and intense motivation to succeed provides a huge opportunity for learning from peers.  I’d personally like to thank off the developers with whom I worked – I learned something from each and every one of you.  I hope to see and work with all of you again someday. GiveCamp provides an opportunity for you to work outside of your comfort zone. While it’s always nice to be an expert, it’s also valuable to work on a project where you have little or no direct experience.  My team focused on a complete reworking of our organizations message and a complete new website redesign and deployment using WordPress.  While I’d used WordPress for my blog, and had some experience, this is completely unrelated to my professional work.  In fact, nobody on our team normally worked directly with the technologies involved – yet together we managed to succeed in delivering our goals.  As developers, it’s easy to want to stay abreast of new technology surrounding our expertise, but its rare that we get a chance to sit down and work on something practical that is completely outside of our normal realm of work.  I’m a desktop developer by trade, and spent much of the weekend working with CSS and Photoshop.  Many of the projects organizations need don’t match perfectly with the skill set in the room – yet all of the software professionals rose to the occasion and delivered practical, usable applications. GiveCamp is a short term, known commitment. While this seems obvious, I think it’s an important aspect to remember.  This is a huge part of what makes it successful – you can work, completely focused, on a project, then walk away completely when you’re done.  There is no expectation of continued involvement.  While many of the professionals I’ve talked to are willing to contribute some amount of their time beyond the camp, this is not expected. The freedom this provides is immense.  In addition, the motivation this brings is incredibly valuable.  Every developer in the room was very focused on delivering in time – you have one shot to get it as good as possible, and leave it with the organization in a way that can be maintained by them.  This is a rare experience – and excellent practice at time management for everyone involved. GiveCamp provides a great way to meet and network with your peers. Not only do you get to network with other software professionals in your area – you get to network with amazing people.  Every single person in the room is there to try to help people.  The balance of altruism, intelligence, and expertise in the room is something I’ve never before experienced. During the presentations of what was accomplished, I felt blessed to participate.  I know many people in the room were incredibly touched by the level of dedication and accomplishment over the weekend. GiveCamp is fun. At the end of the experience, I would have signed up again, even if it was a painful, tedious weekend – merely due to the amazing accomplishments achieved throughout the event.  However, the event is fun.  Everybody I talked to, the entire weekend, was having a good time.  While there were many faces focused into a near grimace at times (including mine, I’ll admit), this was always in response to a particularly challenging problem or task.  The challenges just added to the overall enjoyment of the weekend – part of why I became a developer in the first place is my love for challenge and puzzles, and a short deadline using unfamiliar technology provided plenty of opportunity for puzzles.  As soon as people would stand up, it was another smile.   If you’re a developer, I’d recommend looking at GiveCamp more closely.  Watch for an event in your area.  If there isn’t one, consider building a team and organizing an event.  The experience is worth the commitment.

  • Creating a level editor event system

    - by Vaughan Hilts
    I'm designing a level editor for game, and I'm trying to create sort of an 'event' system so I can chain together things. If anyone has used RPG Maker, I'm trying to do similar to their system. Right now, I have an 'EventTemplate' class and a bunch of sub-classed 'EventNodes' which basically just contain properties of their data. Orginally, the IAction and IExecute interface performed logic but it was moved into a DLL to share between the two projects. Question: How can I abstract logic from data in this case? Is my model wrong? Isn't cast typing expensive to parse these actions all the time? Should I write a 'Processor' class to execute these all? But then these actions that can do all sorts of things need to interact with all sorts of sub-systems.

  • Using Mock for event listeners in unit-testing

    - by phtrivier
    I keep getting to test this kind of code (language irrelevant) : public class Foo() { public Foo(Dependency1 dep1) { this.dep1 = dep1; } public void setUpListeners() { this.dep1.addSomeEventListener(.... some listener code ...); } } Typically, you want to test what when the dependency fires the event, the class under tests reacts appropriately (in some situation, the only purpose of such classes is to wire lots of other components, that can be independently tested. So far, to test this, I always end up doing something like : creating a 'stub' that implements both a addXXXXListener, that simply stores the callback, and a fireXXXX, that simply calls any registered listener. This is a bit tedious since you have to create the mock with the right interface, but that can do use an introspective framework that can 'spy' on a method, and inject the real dependency in tests Is there a cleaner way to do this kind of things ?

  • What is So Unique About Node.js?

    - by Adrian Shum
    Recently there has been a lot of praise for Node.js. I am not a developer that has had much exposure to network application. From my bare understanding of Nodes.js, its strength is: we have only one thread handling multiple connections, providing an event-based architecture. However, for example in Java, I can create only one thread using NIO/AIO (which is non-blocking APIs from my bare understanding), and handle multiple connections using that thread, and I provide an event-based architecture to implement the data handling logic (shouldn't be that difficult by providing some callback etc) ? Given JVM being a even more mature VM than V8 (I expect it to run faster too), and event-based handling architecture seems to be something not difficult to create, I am not sure why Node.js is attracting so much attention. Did I miss some important points?

  • Parleys Testimonial at GlassFish Community Event, JavaOne 2012

    - by arungupta
    Parleys.com is an e-learning platform that provide a unique experience of online and offline viewing presentations, with integrated movies and chaptering, from the top notch developer conferences and about 40 JUGs all around the world. Stephan Janssen (the Devoxx man and Parleys webmaster) presented at the GlassFish Community Event at JavaOne 2012 and shared why they moved from Tomcat to GlassFish. The move paid off as GlassFish was able to handle 2000 concurrent users very easily. Now they are also running Devoxx CFP and registration on this updated infrastructure. The GlassFish clustering, the asadmin CLI, application versioning, and JMS implementation are some of the features that made them a happy user. Recently they migrated their application from Spring to Java EE 6. This allows them to get locked into proprietary frameworks and also avoid 40MB WAR file deployments. Stateless application, JAX-RS, MongoDB, and Elastic Search is their magical forumla for success there. Watch the video below showing him in full action: More details about their infrastructure is available here.

How can I get 3D coordinated from this? I have already looked gluProject and NeHe. But I dont know how to implement this in my project, it shows that there is no GLdouble,GLfloat class.

First config: To be able to connect to the management interface, your user must be added to the Performance Log Users group. After you make this change, you must log off and log back on as the token is only added to your login token when you log on. I forgot this and spent ages trying to work out why I couldn't connect.

  • Event Handling in jQuery

    - by bipinjoshi
    In the previous part of this series I discussed how HTML DOM can be manipulated using jQuery. Now let's proceed with one of the most common task you do in JavaScript - handling events. jQuery streamlines the JavaScript event handling mechanism by providing you a uniform and easy way to wire events with their handlers without bothering about the cross browser issues. As an example we will create a custom context menu (shortcut menu or right click menu) that displays some options specific to our website instead of the normal context menu of the browser.http://www.bipinjoshi.net/articles/fc9bf7fb-4b81-48cf-9b2d-cee10d2de2f9.aspx

  • How Would I create alternate players (Turn base Event)

    The picture above shows 2 players. Each containing 3 characters. I want to know how to make a Turn based event starting with player 1 alternating turns with player 2. And in every alternation each character gets a turn. If a character dies, the next character on the same team goes, and so on. How would I create this? Is there a tutorial? I haven't made any turn-based games so I don't know how to program these kinds of stuff.
