Abstract: A JavaScript interpreter may be interfaced with a JavaScript library of host objects implemented in Java. A JavaScript program may be accessed and parsed, an intermediate representation of the program may be generated, and the intermediate representation may be executed by interfacing with the library of host objects. In one embodiment, the JavaScript program is embedded in HTML documents in a Web browser. The browser is programmed to intercept the JavaScript code and pass execution control to an interpreter engine implemented in Java. The interpreter engine may access the program's library of host objects through an interface to the library and execute the intermediate representation to produce the desired results as programmed in the original JavaScript source program. The implementation of the interface enables the implementation of the interpreter engine to be independent from the implementation of the library of host objects and independent from the implementation of the browser.

Abstract: A JavaScript program may be represented in an intermediate form to be executed by a JavaScript interpreter. A browser may be configured to intercept JavaScript code and pass execution control to a Java-based interpreter engine. The instructions are converted by a representation generator component of the engine into an intermediate representation equivalent using the Java programming language. The representation scheme may be suitable for execution by a stack-machine implemented interpreter. The representation scheme may use Java classes and objects, and create logical commands representing the JavaScript program. The intermediate representation may be stored as Java objects in a stack data structure. The stack data structure may be constructed from an array of elements, where each element is either an operator or an operand, and where each element derives from an abstract Java class with generic functionality and each element contains data relating to the operator or data type it represents.

Abstract: The present invention is a calendaring system implemented as a JavaScript application for program execution on individual Internet browsers after being downloaded by a webserver. The JavaScript application generates HTML on-the-fly and a graphical user interface is displayed on a user's screen. The result is an interactive scheduling system that can be shared between users on the Internet.

Abstract: From the Publisher: This unique book provides an introduction to programming on the Internet. Class-tested over a two-year period, this text covers the "nuts and bolts" of Internet programming. In addition to core fundamentals, readers are introduced to Web page construction HTML, managing an account on a web server, client-server model, and JavaScript programming.

Abstract: Complex graphical user interfaces (GUIs) that support a large amount of user interaction require a fast response time, a rich set of building blocks for an esthetic look-and-feel, and a development environment that supports ongoing change. On the World Wide Web, client-side technologies offer more of these features than do server-side solutions. Java and JavaScript are the two most popular languages used for client-side GUI implementations. Java implementations require a user to download a plug-in that contains a virtual machine to execute the Java byte-code. The installation and maintenance of this plug-in is sometimes an unsurmountable barrier to using Java. JavaScript lacks some of the desirable features of Java, such as easy to use object-oriented features and having a GUI class library, but does not require a plug-in. We have enhanced JavaScript by implementing a new language Object-JavaScript (OJS) and by providing an OJS library of GUI components, thus making it a viable alternative to Java.
