问题 I'm wondering if there is any build-in support for the HTML5 Notification feature in Gecko browsers so far? Maybe some hidden developer thingy ? I'm aware of WebKits window.webkitNotifications which works great, so, is there a Firefox implementation ? Update After searching and reading some W3C HTML5 specs, I'm maybe a little bit off here. I can't find any Notification feature anywhere there. Am I facing wrong facts here? Is that just a "very own webkit implementation"? 回答1: To start with

问题 I just finished building a RESTful API for one of my latest apps. I also built a simple admin interface scaffolding class that will enumerate resources and build simple forms and tables to edit, create, delete etc. For updating and deleting resources, the class outputs a form with methods of PUT and DELETE, pretty simple: <form action="/posts/xxxxxxx" method="DELETE"> <input type="submit" value="Delete" /> </form> and <form action="/posts/xxxxxxx" method="PUT"> <input type="text" name=

问题 I have searched many a page on wikipedia, the official GS1 specifications, but have yet to find a definite answer to the question What is the actual HEX / binary value of the GS1 FNC1 character? There is much information about how to use the GS1 identifiers, how to print the barcodes with ZPL and how to encode the FNC1, but I want to know the actual HEX value of that character. 回答1: The special function characters such as FNC1 through FNC4 do not have any direct ASCII representation. Each

问题 Basically that's the question, how is one supposed to construct a Document object from a string of HTML dynamically in javascript? 回答1: There are two methods defined in specifications, createDocument from DOM Core Level 2 and createHTMLDocument from HTML5. The former creates an XML document (including XHTML), the latter creates a HTML document. Both reside, as functions, on the DOMImplementation interface. var impl = document.implementation, xmlDoc = impl.createDocument(namespaceURI,

问题 There is a hack to make work :focus pseudoclass for div elements: adding to div tabindex . Like this: .testFocus:focus{ background: red; } <div class="testFocus" tabindex="0">awesomeDiv</div> Is this behavior specified somewhere in W3C documents (where?) or is it just a non-documented hack? "This behavior" consists of: div element is not focusable by default. div element with tabindex is focusable. 回答1: tabindex is one of the global attributes. This means it can be specified on all HTML

问题 How to check if some DOM element in another DOM element tree? For example to hide menu when you click on main page content instead of menu you can: document.addEventListener(function (e) { var node = e.target; do { if (node.classList.contains('menu-area')) return; node = node.parentNode; } while (node instanceof HTMLElement); closeMenu(); }); Note that usual solution to hide menu when you click to non-menu area is event.stopPropagation() on menu and non-conditional document.addEventListener()

问题 I'm trying to explore Behavior Driven Design and Domain Driven Design. I'm getting that written specifications drive the tests in BDD, but also that business logic can be encapsulated using the specification pattern for re-use in domain objects and repositories, etc. Are these basically the same concept just used in different ways, used in conjunction together, or am I completely confusing the concepts? Please shed some light, if possible. 回答1: BDD or context specification is a style of

问题 I'm making a package for Atom, and Travis CI keeps telling me my build failed. Update : I created a blank spec file and now my builds are passing. You can see my package here: https://travis-ci.org/frayment/language-jazz The console is telling me: sh: line 105: ./spec: No such file or directory Missing spec folder! Please consider adding a test suite in I went looking around at Atom packages on GitHub for 'spec' files and they seem to be CoffeeScript based, but I can't understand what on
