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. -
Ecma International External Liaison Report for 2013-2014
Ecma/TC39/2014/029 Ecma/TC49/2014/010 Ecma International External Liaison Report for 2013–2014 Prepared for the ISO/IEC JTC 1/SC 22 Plenary in Madrid, Spain September 8–9, 2014 Prepared by Rex Jaeschke [email protected] Date: 2014-07-17 Recommendation to SC 22 regarding the Portable Common Tool Environment (PCTE) Standards The draft agenda for the 2014 Plenary of SC 22 lists the following standards as being up for Periodic Review: • ISO/IEC 13719-1:1998 Information technology -- Portable Common Tool Environment (PCTE) – Part 1: Abstract specification • ISO/IEC 13719-2:1998 Information technology -- Portable Common Tool Environment (PCTE) – Part 2: C programming language binding • ISO/IEC 13719-3:1998 Information technology -- Portable common tool environment (PCTE) – Part 3: Ada programming language binding • ISO/IEC 13719-4:1998 Information technology -- Portable Common Tool Environment (PCTE) – Part 4: IDL binding (Interface Definition Language) These standards were developed and published by Ecma, and then Fast-Tracked to JTC 1. No work has been done on them since and there is no longer a Technical Committee for PCTE. As such, Ecma recommends that SC 22 stabilize these standards. Ecma (www.ecma-international.org) currently has two Technical Committees, TC39 and TC49 (the latter having multiple Task Groups), with SC 22-related projects, as follows: 1. TC39 (ECMAScript language): ECMAScript 5th edition was adopted by the Ecma General Assembly in December 2009, and then published as ISO/IEC 16262:2011 (which ECMA-262 edition 5.1 now matches). The editor of record for the standard is Allen Wirfs-Brock. -

Centre-Ville Montréal, Québec Canada H3C 3J7 [email protected] http://www.iro.umontreal.ca/~lapalme/ForestInsteadOfTheTrees/ Publication date April 14, 2019 XML to PDF by RenderX XEP XSL-FO Formatter, visit us at http://www.renderx.com/ XML: Looking at the Forest Instead of the Trees Guy Lapalme Professor Département d©informatique et de recherche opérationnelle Université de Montréal C.P. 6128, Succ. Centre-Ville Montréal, Québec Canada H3C 3J7 [email protected] http://www.iro.umontreal.ca/~lapalme/ForestInsteadOfTheTrees/ Publication date April 14, 2019 Abstract This tutorial gives a high-level overview of the main principles underlying some XML technologies: DTD, XML Schema, RELAX NG, Schematron, XPath, XSL stylesheets, Formatting Objects, DOM, SAX and StAX models of processing. They are presented from the point of view of the computer scientist, without the hype too often associated with them. We do not give a detailed description but we focus on the relations between the main ideas of XML and other computer language technologies. A single compact pretty-print example is used throughout the text to illustrate the processing of an XML structure with XML technologies or with Java programs. We also show how to create an XML document by programming in Java, in Ruby, in Python, in PHP, in E4X (Ecmascript for XML) and in Swift. The source code of the example XML ®les and the programs are available either at the companion web site of this document or by clicking on the ®le name within brackets at the start of the caption of each example. -
