Java描述语言[一种在HTML上使用的描述语言,能提高HTML的操作能力]

(Formerly "LiveScript") {Netscape}'s simple,
cross-{platform}, {World-Wide Web} {scripting language}, only
very vaguely related to {Java} (which is a {Sun} trademark).
JavaScript is intimately tied to the {World-Wide Web}, and
currently runs in only three environments - as a {server}-side
{scripting} language, as an embedded language in
{server-parsed HTML}, and as an embedded language run in web
{browsers} where it is the most important part of {DHTML}.

JavaScript has a simplified {C}-like {syntax} and is tightly
integrated with the browser {Document Object Model}. It is
useful for implementing enhanced {forms}, simple web
{database} {front-ends}, and navigation enhancements. It is
unusual in that the {scope} of {variables} extends throughout
the function in which they are declared rather than the
smallest enclosing block as in C.

JavaScript originated from {Netscape} and, for a time, only
their products supported it. {Microsoft} now supports a
work-alike which they call JScript. The resulting
inconsistencies make it difficult to write JavaScript that
behaves the same in all browsers. This could be attributed to
the slow progress of JavaScript through the standards bodies.

JavaScript runs "100x" slower than {C}, as it is purely
interpreted ({Java} runs "10x" slower than C code).
{Netscape} and allies say JavaScript is an "open standard" in
an effort to keep {Microsoft} from monopolising web software
as they have desktop software. {Netscape} and {Sun} have
co-operated to enable {Java} and JavaScript to exchange
messages and data.

See also {VBScript}.
