Offline Web Applications. You are here: Home Dive Into HTML5 Diving In What is an offline web application?
At first glance, it sounds like a contradiction in terms. Web pages are things you download and render. Downloading implies a network connection. At its simplest, an offline web application is a list of URLs — HTML, CSS, JavaScript, images, or any other kind of resource. From there, most of the work is up to you, the web developer. The Cache Manifest. The future of web apps is — ready? — isomorphic JavaScript. Editor’s note: Spike Brehm, the author of this post, is just one of the amazing hackers we’ve got speaking at DevBeat 2013, our first-ever developer conference taking place next week, Nov. 12-13 in San Francisco.
It’s a hands-on event packed with master classes, presentations, Q&As, and a sweet hardware hackathon, all aimed at boosting your code repertoire, security knowledge, hacking prowess, and career development. Seats are few and going fast, so register now. At Airbnb, we’ve learned a lot over the past few years while building rich web experiences. We dived into the single-page app world in 2011 with our mobile web site, and have since launched Wish Lists and our newly-redesigned search page, among others. Each of these is a large JavaScript app, meaning that the bulk of the code runs in the browser in order to support a more modern, interactive experience. JavaScript grows up The single-page app Trouble in paradise Maintainability A hybrid approach.

I decided to write a quick blog post about this because much of the documentation and examples about this seems to be a bit scattered.
What this achieves is the ability to upload any number of files with any other type of data in one request. For this example we’ll send up JSON data along with some files. File upload directive First we’ll create a simple custom file upload angular directive The usage of this is simple: The ‘multiple’ parameter indicates that the user can select multiple files to upload which this example fully supports. In the directive we ensure a new scope is created and then listen for changes made to the file input element. Mark-up & the controller Next we’ll create a controller to: Create a model to bind to Create a collection of files Consume this event so we can assign the files to the collection Create a method to post it all to the server With the controller in place, the mark-up might look like this (and will display the file names of all of the files selected):

Using genetify on your webpage · gregdingle/genetify Wiki. Using genetify on your webpage Loaded in a webpage, genetify.js lets you create experiments in your code.
Each experiment tests a group of alternatives and chooses the best one. Genetify.js works with groups of CSS rules, javascript variables or HTML tags. The groups are defined implicitly by adding special suffixes like “_vBeta” to an object’s original name. Experiments are evaluated by user feedback. The overarching aim of genetify.js is to make the programming of code experiments as natural as possible. Terminology Groups of CSS rules, javascript variables or HTML tags whose members are meant to be tested on users will be called genes, inspired by the unit of selection in biological evolution. The members of those groups will be called variants because they should each vary one from the other in some purposeful way. To say that something is genetified is to say that it has been branched off into multiple variants and is ready to be tested.
