It provides a machine abstraction and hardware-agnostic instruction sets, where a high-level programming language can target the compilation to the Wasm instead of specific hardware architecture. The JavaScript engine implements the Wasm specification and recompiles the Wasm instruction to the target machine instruction where the program is executed. Technically, Wasm is similar to a popular virtual machine bytecode, such as Java Virtual Machine (JVM) or Microsoft Intermediate Language (MSIL). -

Document Object Model
Document Object Model DOM DOM is a programming interface that provides a way for the values and structure of an XML document to be accessed and manipulated. Tasks that can be performed with DOM . Navigate an XML document's structure, which is a tree stored in memory. Report the information found at the nodes of the XML tree. Add, delete, or modify elements in the XML document. DOM represents each node of the XML tree as an object with properties and behavior for processing the XML. The root of the tree is a Document object. Its children represent the entire XML document except the xml declaration. On the next page we consider a small XML document with comments, a processing instruction, a CDATA section, entity references, and a DOCTYPE declaration, in addition to its element tree. It is valid with respect to a DTD, named root.dtd. <!ELEMENT root (child*)> <!ELEMENT child (name)> <!ELEMENT name (#PCDATA)> <!ATTLIST child position NMTOKEN #REQUIRED> <!ENTITY last1 "Dover"> <!ENTITY last2 "Reckonwith"> Document Object Model Copyright 2005 by Ken Slonneger 1 Example: root.xml <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE root SYSTEM "root.dtd"> <!-- root.xml --> <?DomParse usage="java DomParse root.xml"?> <root> <child position="first"> <name>Eileen &last1;</name> </child> <child position="second"> <name><![CDATA[<<<Amanda>>>]]> &last2;</name> </child> <!-- Could be more children later. --> </root> DOM imagines that this XML information has a document root with four children: 1. A DOCTYPE declaration. 2. A comment. 3. A processing instruction, whose target is DomParse. 4. The root element of the document. The second comment is a child of the root element. -
Extensible Markup Language (XML) and Its Role in Supporting the Global Justice XML Data Model
Extensible Markup Language (XML) and Its Role in Supporting the Global Justice XML Data Model Extensible Markup Language, or "XML," is a computer programming language designed to transmit both data and the meaning of the data. XML accomplishes this by being a markup language, a mechanism that identifies different structures within a document. Structured information contains both content (such as words, pictures, or video) and an indication of what role content plays, or its meaning. XML identifies different structures by assigning data "tags" to define both the name of a data element and the format of the data within that element. Elements are combined to form objects. An XML specification defines a standard way to add markup language to documents, identifying the embedded structures in a consistent way. By applying a consistent identification structure, data can be shared between different systems, up and down the levels of agencies, across the nation, and around the world, with the ease of using the Internet. In other words, XML lays the technological foundation that supports interoperability. XML also allows structured relationships to be defined. The ability to represent objects and their relationships is key to creating a fully beneficial justice information sharing tool. A simple example can be used to illustrate this point: A "person" object may contain elements like physical descriptors (e.g., eye and hair color, height, weight), biometric data (e.g., DNA, fingerprints), and social descriptors (e.g., marital status, occupation). A "vehicle" object would also contain many elements (such as description, registration, and/or lien-holder). The relationship between these two objects—person and vehicle— presents an interesting challenge that XML can address. -

Both projects have a strong focus on MathPlayer is a plug-in to Microsoft’s Internet Explorer (IE) that two-way translation between MathML and multiple braille math renders MathML[11] visually. It also contains a number of codes. They also include some standalone software for voicing features that make mathematical expressions accessible to people and navigating math. with print-disabilities. MathPlayer integrates with many screen Our work differs from previous work mainly in its focus – readers including JAWS and Window-Eyes. MathPlayer also MathPlayer is a mainstream application that is also designed to works with a number of TextHELP!’s learning disabilities work with popular assistive technology (AT) software. Our goal is products. to allow people to continue to use tools that they are already familiar with such as JAWS and IE, and not require them to use a Categories and Subject Descriptors different browser simply because the document they are reading H.5.4 [Information Systems]: Information Interfaces and contains mathematical expressions.

HTML5 Indexeddb
HHTTMMLL55 -- IINNDDEEXXEEDDDDBB http://www.tutorialspoint.com/html5/html5_indexeddb.htm Copyright © tutorialspoint.com The indexeddb is a new HTML5 concept to store the data inside user's browser. indexeddb is more power than local storage and useful for applications that requires to store large amount of the data. These applications can run more efficiency and load faster. Why to use indexeddb? The W3C has announced that the Web SQL database is a deprecated local storage specification so web developer should not use this technology any more. indexeddb is an alternative for web SQL data base and more effective than older technologies. Features it stores key-pair values it is not a relational database IndexedDB API is mostly asynchronous it is not a structured query language it has supported to access the data from same domain IndexedDB Before enter into an indexeddb, we need to add some prefixes of implementation as shown below window.indexedDB = window.indexedDB || window.mozIndexedDB || window.webkitIndexedDB || window.msIndexedDB; window.IDBTransaction = window.IDBTransaction || window.webkitIDBTransaction || window.msIDBTransaction; window.IDBKeyRange = window.IDBKeyRange || window.webkitIDBKeyRange || window.msIDBKeyRange if (!window.indexedDB) { window.alert("Your browser doesn't support a stable version of IndexedDB.") } Open an IndexedDB database Before creating a database, we have to prepare some data for the data base.let's start with company employee details. const employeeData = [ { id: "01", name: "Gopal K Varma", age: 35, -

Document Object Model
Document Object Model CITS3403: Agile Web Development Semester 1, 2021 Introduction • We’ve seen JavaScript core – provides a general scripting language – but why is it so useful for the web? • Client-side JavaScript adds collection of objects, methods and properties that allow scripts to interact with HTML documents dynamic documents client-side programming • This is done by bindings to the Document Object Model (DOM) – “The Document Object Model is a platform- and language-neutral interface that will allow programs and scripts to dynamically access and update the content, structure and style of documents.” – “The document can be further processed and the results of that processing can be incorporated back into the presented page.” • DOM specifications describe an abstract model of a document – API between HTML document and program – Interfaces describe methods and properties – Different languages will bind the interfaces to specific implementations – Data are represented as properties and operations as methods • https://www.w3schools.com/js/js_htmldom.asp The DOM Tree • DOM API describes a tree structure – reflects the hierarchy in the XTML document – example... <html xmlns = "http://www.w3.org/1999/xhtml"> <head> <title> A simple document </title> </head> <body> <table> <tr> <th>Breakfast</th> <td>0</td> <td>1</td> </tr> <tr> <th>Lunch</th> <td>1</td> <td>0</td> </tr> </table> </body> </html> Execution Environment • The DOM tree also includes nodes for the execution environment in a browser • Window object represents the window displaying a document – All properties are visible to all scripts – Global variables are properties of the Window object • Document object represents the HTML document displayed – Accessed through document property of Window – Property arrays for forms, links, images, anchors, … • The Browser Object Model is sometimes used to refer to bindings to the browser, not specific to the current page (document) being rendered. -
