ExtJS
Ext JS is a JavaScript application framework for building interactive cross-platform web applications using techniques such as Ajax, DHTML and DOM scripting. It can be used as a simple component framework (for example, to create dynamic grids on otherwise static pages) but also as a full framework for building single-page applications (SPAs). Originally built as an add-on library extension of YUI by Jack Slocum on April 15, 2007, Ext JS has had no dependencies on external libraries beginning with version 1.1. Nowadays, Ext JS can be used both as a single script (with all classes and components in one file) or by building the application with the Sencha Cmd. Features GUI controls (components) Ext JS includes a set of GUI-based form controls (or " widgets") for use within web applications: * text field and textarea input controls * date fields with a pop-up date-picker * numeric fields * list box and combo boxes * radio and checkbox controls * html editor control * grid control ...

Single-page Application
A single-page application (SPA) is a web application or website that interacts with the user by dynamically rewriting the current web page with new data from the web server, instead of the default method of a web browser loading entire new pages. The goal is faster transitions that make the website feel more like a native app. In a SPA, a page refresh never occurs; instead, all necessary HTML, JavaScript, and CSS code is either retrieved by the browser with a single page load,Flanagan, David,JavaScript - The Definitive Guide, 5th ed., ''O'Reilly, Sebastopol, CA, 2006'', p.497 or the appropriate resources are dynamically loaded and added to the page as necessary, usually in response to user actions. History The origins of the term ''single-page application'' are unclear, though the concept was discussed at least as early as 2003. Stuart Morris, a programming student at Cardiff University, Wales, wrote the Self-Contained website at slashdotslash.com with the same goals and function ...

Prototype JavaScript Framework
The Prototype JavaScript Framework is a JavaScript framework created by Sam Stephenson in February 2005 as part of Ajax support in Ruby on Rails. It is implemented as a single file of JavaScript code, usually named prototype.js. Prototype is distributed standalone, but also as part of larger projects, such as Ruby on Rails, script.aculo.us and Rico. As of March 2021, according to w3techs, Prototype is used by 0.6% of all websites. Features Prototype provides various functions for developing JavaScript applications. The features range from programming shortcuts to major functions for dealing with XMLHttpRequest. Prototype also provides library functions to support classes and class-based objects. In JavaScript, object creation is prototype-based instead: an object creating function can have a prototype property, and any object assigned to that property will be used as a prototype for the objects created with that function. The Prototype framework is not to be confused with this l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sencha Touch
Sencha Touch is a user interface (UI) JavaScript library, or web framework, specifically built for the Mobile Web. It can be used by Web developers to develop user interfaces for mobile web applications that look and feel like native applications on supported mobile devices. It is based on web standards such as HTML5, CSS3 and JavaScript. The goal of Sencha Touch is to facilitate quick and easy development of HTML5 based mobile apps which run on Android, iOS, Windows, Tizen and BlackBerry devices, simultaneously allowing a native look and feel to the apps. Version history and support Sencha Touch is a product of Sencha, which was formed after popular JavaScript library projects Ext JS, jQTouch and Raphaël were combined. The first release of Sencha Touch, version 0.90 beta, was made available on July 17, 2010. This beta release supported devices running Android, and iOS (on iPhone, iPod Touch, iPad). Subsequently, the first stable version, 1.0, was released in Novem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
JavaScript Library
A JavaScript library is a library of pre-written JavaScript code that allows for easier development of JavaScript-based applications, especially for AJAX and other web-centric technologies. Libraries With the expanded demands for JavaScript, an easier means for programmers to develop such dynamic interfaces was needed. Thus, JavaScript libraries and JavaScript widget libraries were developed, allowing for developers to concentrate more upon more distinctive applications of Ajax. This has led to other companies and groups, such as Microsoft and Yahoo! developing their own JavaScript-based user interface libraries, which find their way into the web applications developed by these companies. Some JavaScript libraries allow for easier integration of JavaScript with other web development technologies, such as CSS, PHP, Ruby, and Java. While others provide utilities, often in the form of JavaScript functions, to make repetitive and complex tasks less taxing. Many libraries include code t ...

Radio Button
A radio button or option button is a graphical control element that allows the user to choose only one of a predefined set of mutually exclusive options. The singular property of a radio button makes it distinct from checkboxes, where the user can select and unselect any number of items. Radio buttons are arranged in groups of two or more and displayed on screen as, for example, a list of circular holes that can contain white space (for unselected) or a dot (for selected). Each radio button is normally accompanied by a label describing the choice that the radio button represents. The choices are mutually exclusive; when the user selects a radio button, any previously selected radio button in the same group becomes deselected (making it so only one can be selected). Selecting a radio button is done by clicking the mouse on (or touching the screen over) the button, or the caption, or by using a keyboard shortcut. It is possible that initially none of the radio buttons in a group ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Material Design
Material Design (codenamed Quantum Paper) is a design language developed by Google in 2014. Expanding on the "cards" that debuted in Google Now, Material Design uses more grid-based layouts, responsive animations and transitions, padding, and depth effects such as lighting and shadows. Google announced Material Design on June 25, 2014, at the 2014 Google I/O conference. The main purpose of Material Design is the creation of a new visual language that combines principles of good design with technical and scientific innovation. Designer Matías Duarte explained that, "unlike real paper, our digital material can expand and reform intelligently. Material has physical surfaces and edges. Seams and shadows provide meaning about what you can touch." Google states that their new design language is based on paper and ink but implementation takes place in an advanced manner. In 2018, Google detailed a revamp of the language, with a focus on providing more flexibility for designers to cre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Model View ViewModel
A model is an informative representation of an object, person or system. The term originally denoted the plans of a building in late 16th-century English, and derived via French and Italian ultimately from Latin ''modulus'', a measure. Models can be divided into physical models (e.g. a model plane) and abstract models (e.g. mathematical expressions describing behavioural patterns). Abstract or conceptual models are central to philosophy of science, as almost every scientific theory effectively embeds some kind of model of the physical or human sphere. In commerce, "model" can refer to a specific design of a product as displayed in a catalogue or show room (e.g. Ford Model T), and by extension to the sold product itself. Types of models include: Physical model A physical model (most commonly referred to simply as a model but in this context distinguished from a conceptual model) is a smaller or larger physical copy of an object. The object being modelled may be small ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Model–view–controller
Model–view–controller (MVC) is a software architectural pattern commonly used for developing user interfaces that divide the related program logic into three interconnected elements. This is done to separate internal representations of information from the ways information is presented to and accepted from the user. Traditionally used for desktop graphical user interfaces (GUIs), this pattern became popular for designing web applications. Popular programming languages have MVC frameworks that facilitate the implementation of the pattern. __TOC__ History One of the seminal insights in the early development of graphical user interfaces, MVC became one of the first approaches to describe and implement software constructs in terms of their responsibilities. Trygve Reenskaug created MVC while working on Smalltalk-79 as a visiting scientist at the Xerox Palo Alto Research Center (PARC) in the late 1970s.

Vector Markup Language
Vector Markup Language (VML) is an obsolete XML-based file format for two-dimensional vector graphics. It was specified in Part 4 of the Office Open XML standards ISO/IEC 29500 and ECMA-376. According to the specification, VML is a deprecated format included in Office Open XML for legacy reasons only. VML was used extensively in MS Office 2007 Word, Excel and PowerPoint documents. In 2012, with the release of Internet Explorer 10, VML became obsolete and is no longer supported by Internet Explorer standard mode. It is a legacy feature that is available in Internet Explorer 10 only when the browser is set to run in modes that emulate the functionality of previous versions of Internet Explorer 6, 7, 8, and 9. History VML was submitted to the World Wide Web Consortium (W3C) in 1998 by Autodesk, Hewlett-Packard, Macromedia, Microsoft, and Vision. Around the same time other competing W3C submissions were received in the area of web vector graphics, such as Precision Graphics M ...

Scalable Vector Graphics
Scalable Vector Graphics (SVG) is an XML-based vector image format for defining two-dimensional graphics, having support for interactivity and animation. The SVG specification is an open standard developed by the World Wide Web Consortium since 1999. SVG images are defined in a vector graphics format and stored in XML text files. SVG images can thus be scaled in size without loss of quality, and SVG files can be searched, indexed, scripted, and compressed. The XML text files can be created and edited with text editors or vector graphics editors, and are rendered by the most-used web browsers. Overview SVG has been in development within the World Wide Web Consortium (W3C) since 1999 after six competing proposals for vector graphics languages had been submitted to the consortium during 1998 (see below). The early SVG Working Group decided not to develop any of the commercial submissions, but to create a new markup language that was informed by but not really based on any ...

Slider (computing)
A slider or track bar is a graphical control element with which a user may set a value by moving an indicator, usually horizontally. In some cases user may also click on a point on the slider to change the setting. It is different from a scrollbar in that it is not continuous but used to adjust a value without changing the format of the display or the other information on the screen. Its most popular use is for viewing and jumping to a playback position in media player software. Usage with progress bars Sliders are also combined with progress bars in the playback of streaming media Streaming media is multimedia that is delivered and consumed in a continuous manner from a source, with little or no intermediate storage in network elements. ''Streaming'' refers to the delivery method of content, rather than the content it ... over a network connection (e.g., YouTube videos) in order to show the content buffering position versus the playback position.
