HTML Series

The W3C HTML standard includes support for client-side scripting. HTML, an initialism of HyperText Markup Language, is the predominant Markup language for Web pages It provides a means to describe the structure HTML has been in use since 1991, but HTML 40 (December 1997 was the first standardized version where international characters were given reasonably complete treatment Dynamic HTML, or DHTML, is a collection of technologies used together to create interactive and animated Web sites by using a combination of a static Markup In HTML and XHTML, a font face or font family is the typeface that is applied to some text An HTML editor is a software application for creating Web pages Although the HTML markup of a web page can be written with any Text editor, specialized In Computing, an HTML element indicates structure in an HTML document and a way of hierarchically arranging content A layout engine, or rendering engine, is software that takes marked up content (such as HTML, XML, image files etc Quirks mode refers to a technique used by some Web browsers for the sake of maintaining backwards compatibility with Web pages designed for older browsers instead of Web style sheets are a form of Separation of presentation and content for Web design in which the markup (i Web pages authored using hypertext markup language ( HTML) may contain multilingual text represented with the Unicode universal character set.

"Scripting" redirects here For other uses see Script. A web page or webpage is a resource of information that is suitable for the World Wide Web and can be accessed through a Web browser. A particular client-side application, such as a web browser, may support several script languages. A web browser is a software application which enables a user to display and interact with text images videos music games and other information typically located on a Script code may be executed as the document loads or at a later time.

Script code can be written directly in the HTML document inside:

• SCRIPT elements
• Intrinsic event attributes

Script macros

The SCRIPT element type

SCRIPT elements may occur zero or more times within the HEAD and BODY elements. Scripts within script elements are processed as the document loads.

Intrinsic event attributes

Events occur for different elements of a web-page:

• Documents (BODY and FRAMESET)
• Forms
• UI elements (Anchor, Control Element, Image)

Script code may be associated with an event and element by writing code in an HTML attribute. In Computer programming, event-driven programming or event-based programming is a Programming paradigm in which the flow of the program is determined The user interface (or Human Computer Interface) is the aggregate of means by which people&mdash the users '&mdash interact with the System The name of the attribute must be that of a supported intrinsic event for the element (for example, "onLoad"). The script is executed whenever the event occurs for that element. These scripts are mostly Javascript. The HTML intrinsic event model consist of the following events:

• Document
  • onLoad
  • onUnload
• Form
  • onSubmit
  • onReset
• Document and UI elements
  • Focus
    • onFocus
    • onBlur
• UI elements
  • Mouse
    • Movement
      • onMouseOver
      • onMouseOut
      • onMouseMove
    • Button
      • onClick
      • onDblClick
      • onMouseDown
      • onMouseUp
  • Keyboard
    • onKeyPress
    • onKeyDown
    • onKeyUp
  • Other (TEXT/TEXTAREA)
    • Lost focus with modified content
      • onChange (also OPTION)
    • Text selection
      • OnSelect

Some browsers support additional event attributes (outside the standard), such as:

• onResize
• onMove
• onScroll
• onAbort

Script macros

Netscape Navigator supported a feature called "JavaScript entities" or "script macros" by which script code could be included in HTML attribute values, using a syntax similar to that of character entity references. Netscape Navigator and Netscape are the names for the proprietary Web browser popular in the 1990s and the Flagship product of the Netscape In the Markup languages SGML, HTML, XHTML and XML, a character entity reference is a reference to a particular kind of named For example, the code <img width="&{prompt('Width?')};" src="foo. jpg"> calls the JavaScript prompt() function to ask the user how wide the image should be.

The HTML 4.01 specification reserves a syntax for the "future support of script macros" in HTML attributes, but they have not been incorporated into later standards and are not supported by any current browser.
