Attributes and properties. When the browser loads the page, it “reads” (another word: “parses”) the HTML and generates DOM objects from it.
For element nodes, most standard HTML attributes automatically become properties of DOM objects. For instance, if the tag is <body id="page">, then the DOM object has body.id="page". But the attribute-property mapping is not one-to-one! In this chapter we’ll pay attention to separate these two notions, to see how to work with them, when they are the same, and when they are different. DOM properties We’ve already seen built-in DOM properties. DOM nodes are regular JavaScript objects. For instance, let’s create a new property in document.body: Understanding Relationships Between HTML Attributes & DOM Object's Properties. Javascript lato server? E' la scelta giusta?

Frankly, ES6 was already on the way, all that needed to be done is for it to be finalized. Make sure to check out the full spec if you haven’t done so already. ECMAScript 6 improvements include better syntax for classes, along with new methods for strings and Arrays, Promises, Maps and Sets. We keep seeing huge growth with Node.js.

Introduction HTML5 finally provides a standard way to interact with local files, via the File API specification.
As example of its capabilities, the File API could be used to create a thumbnail preview of images as they're being sent to the server, or allow an app to save a file reference while the user is offline. Additionally, you could use client-side logic to verify an upload's mimetype matches its file extension or restrict the size of an upload. The spec provides several interfaces for accessing files from a 'local' filesystem: File - an individual file; provides readonly information such as name, file size, mimetype, and a reference to the file handle.
When used in conjunction with the above data structures, the FileReader interface can be used to asynchronously read a file through familiar JavaScript event handling. Selecting files The first thing to do is check that your browser fully supports the File API: Using form input for selecting. Jlmakes/scrollreveal: Easy scroll animations for web and mobile browsers.
