  • is there a way to inject privileged methods after an object is constructed?

    - by patrickgamer
    I'm trying to write fully automated unit tests in JavaScript and I'm looking for a way to read some private variables in various JS functions. I thought I recalled a way to inject privileged members into a function/object (and found an overwhelming occurrence of "no such thing as private in JS") and yet I can't find any resources indicating how. I'm trying to read through the properties of .prototype but if there's a way, someone out here would know where to direct me faster than I'd find on my own. Thanks

  • style a navigation link when a particular div is shown

    - by Matt Meadows
    I have JQuery working to show a particular div when a certain link is clicked. I have managed to apply the effect I'm after with the main navigation bar through id'ing the body tag and using css to style when the id is found. However, i'd like to apply the same effect to the sub navigation when a certain div is present. How the main navigation is styled: HTML: <nav> <ul> <li id="nav-home"><a href="index.html">Home</a></li> <li id="nav-showreel"><a href="showreel.html">Showreel</a></li> <li id="nav-portfolio"><a href="portfolio.html">Portfolio</a></li> <li>Contact</li> </ul> </nav> CSS: body#home li#nav-home, body#portfolio li#nav-portfolio { background: url("Images/Nav_Underline.png") no-repeat; background-position: center bottom; color: white; } (Other links havent been added to styling as those pages are still in development) How the sub navigation is structured: <nav id="portfolioNav"> <ul> <li id="portfolio-compositing"><a id="compositingWork" href="#">Compositing</a></li> <li id="portfolio-animation"><a id="animationWork" href="#">Animation</a></li> <li id="portfolio-motionGfx"><a id="GFXWork" href="#">Motion Graphics</a></li> <li id="portfolio-3D"><a id="3DWork" href="#">3D</a></li> </ul> </nav> As you can see, its similar format to the main navigation, however i've tried the same approach and it doesn't work :( The Javascript that switches the divs on the navigation click: <script type="text/javascript"> $(document).ready(function() { $('#3DWork').click(function(){ $('#portfolioWork').load('portfolioContent.html #Portfolio3D'); }); $('#GFXWork').click(function(){ $('#portfolioWork').load('portfolioContent.html #motionGraphics'); }); $('#compositingWork').click(function(){ $('#portfolioWork').load('portfolioContent.html #PortfolioCompositing'); }); $('#animationWork').click(function(){ $('#portfolioWork').load('portfolioContent.html #PortfolioAnimation'); }); }); </script> JSFiddle for full HTML & CSS : JSFiddle File The effect I'm After:

  • Where can I find "canonical" sample programs that give quick refreshers for any given language? [on hold]

    - by acheong87
    Note to those close-voting this question: I understand this isn't a conventional programming question and I can agree with the reasoning that it's in the subjective domain (like best-of lists). In other ways though I think it's appropriate because, though it's not a "a specific programming problem," nor concerning "a software algorithm", nor (strictly) concerning "software tools commonly used by programmers", I think it is a "practical, answerable [problem that is] unique to the programming profession," and I think it is "based on an actual [problem I] face." I've been wanting this for some time now, because both approaches of (a) Googling for samples as I write every other line of code and (b) just winging it and seeing what errors crop up, distract me from coding efficiently. This note will be removed if the question gains popularity; this question will be deleted otherwise. I spend most of my time developing in C++, PHP, or Javascript, and every once in a while I have to do something in, say, VBA. In those times, it'd be convenient if I could just put up some sample code on a second monitor, something in between a cheat sheet (often too compact; and doesn't resemble anything that could actually compile/run), and a language reference (often too verbose, or segmented; requires extra steps to search or click through an index), so I can just glance at it and recall things, like how to loop through non-empty cells in a column. I think there's a hidden benefit to seeing formed code, that triggers the right spots in our brains to get back into a language we only need to brush up on. Similar in spirit is how http://ideone.com lets you click "Template" in any given language so you can get started without even doing a search. That template alone tells a lot, sometimes! Case-sensitivity, whitespace conventions, identifier conventions, the spelling of certain types, etc. I couldn't find a resource that pulled together such samples, so if there indeed doesn't exist such a repository, I was hoping this question would inspire professionals and experts to contribute links to the most useful sample code they've used for just this purpose: a keep-on-the-side, form-as-well-as-content, compilable/executable, reminder of a language's basic and oft-used features. Personally I am interested in seeing "samplers" for: VBA, Perl, Python, Java, C# (though for some of these autocompleters in Eclipse, Visual Studio, etc. help enough), awk, and sed. I'm tagging c++, php, and javascript because these are languages for which I'd best be able to evaluate whether proffered sample code matches what I had in mind.

  • What are the standard practices for throwing JavasScript Exceptions?

    - by T.R.
    w3schools says that exceptions can be strings, integers, booleans, or objects, but the example given doesn't strike me as good practice, since exception type checking is done through string comparison. Is this the preferred method of exception handling in JavaScript? Are there built-in exception types (like NullPointerException)? (if so, what are they, what kind of inheritance do they use, and are they preferred over other options?)

  • Detect End of Video Playback in Web Page

    - by Eric J.
    Is there a widely supported video playback technology for web pages that provides an event/hook that can be captured from Javascript when playback reaches the end of the stream? My goal is to provide a web page that plays a video and then asks the user a question about the video once playback is complete. The question would be hidden or disabled until they have actually viewed the video.

  • jQuery plugins: How can I stop divs from overlapping?

    - by anir
    I'm using Masonry and Embedly plugin to display embedded content, I've put together an example in jsfiddle.net/anir/pBtbb/3/ It appears the Masonry plugin loads first and it causes the overlapping problem (they only show correctly when you resize the result window) I've read that I could use callback functions or retrigger Masonry once embedly has finished rendering content, but I don't know how to do it. Can you help me? Is there any other solution to fix this?

  • Block an Order Button

    - by Frank G.
    I am looking for a script that will block or remove an order button to prevent customers from double or triple ordering but clicking the button more then once. I don't know what something like this would be called. But the site was developed in Classic .asp. However I'm going to guess and say this would be javascript or jquery on an image button? Any suggestion or points for this would be a big help!!!! Thanks,
