Abstract

A method, system, and apparatus for extending JavaScript to operate more fully as an object oriented language. A multiple inheritance module may be configured to enable JavaScript to implement multiple inheritance. A messaging module may be configured to enable JavaScript to implement messaging. A polymorphism module may be configured to enable JavaScript to implement polymorphism.

Claims

1. A computer implemented method for extending JavaScript, the method comprising:

executing first JavaScript code that enables the implementation of multiple inheritance between one or more objects, is configured to create a subclass that inherits one or more behaviors from a plurality of objects passed as parameters to the subclass, and is configured to resolve conflicts between inherited behaviors by allowing a newly inherited class to over-ride a function of the same name for a prior parent class;

executing second JavaScript code that enables a central updater to query one or more applications to determine identity (ID) of data currently associated with each application, while the central updater has no knowledge of inner-working of the one or more applications; and

executing third JavaScript code that enables polymorphism in one or more objects;

wherein the first JavaScript code, the second JavaScript code, and the third JavaScript code are part of a JavaScript extension tool stored in a memory of the computer and configured to operate as an extension of a JavaScript environment by being interpreted and executed at run-time.

2. An apparatus for extending JavaScript, the apparatus comprising a central processing unit (CPU) comprising:

a JavaScript extension tool stored in a memory on the apparatus and configured to operate as an extension of a JavaScript environment by being interpreted and executed at run-time, the JavaScript extension tool comprising;

a multiple inheritance module comprising first JavaScript code to implement multiple inheritance by interpreting the first JavaScript code at run-time on the apparatus, wherein the multiple inheritance module is configured to create a subclass that inherits one or more behaviors from a plurality of objects passed as parameters to the subclass, and configured to resolve conflicts between inherited behaviors by allowing a newly inherited class to over-ride a function of the same name for a prior parent class;

a messaging module comprising second JavaScript code to implement messaging by interpreting the second JavaScript code at run-time on the apparatus, wherein the messaging module enables a central updater to query one or more applications to determine identity (ID) of data currently associated with each application, while the central updater has no knowledge of inner-working of the one or more applications; and

a polymorphism module comprising third JavaScript code to implement polymorphism by interpreting the third JavaScript code at run-time on the apparatus.

3. The apparatus of claim 2, wherein the multiple inheritance module enables a user to rename a class in response to the class being overridden by another class.

4. The apparatus of claim 2, wherein the multiple inheritance module accesses a derived gethtml function to determine which of plurality of base classes to call.

5. The apparatus of claim 2, wherein the messaging module is configured to enable objects to communicate using local and global broadcasts.

6. The apparatus of claim 2, wherein the messaging module is configured to enable one or more objects to operate in a state of constant broadcast.

7. The apparatus of claim 2, wherein the messaging module does not slow messaging in response to an increased number of broadcasts.

8. The apparatus of claim 2, wherein the messaging module enables an application instance to broadcast an event message to all other application instances.

9. The apparatus of claim 2, wherein the messaging module enables a listening application instance to take action in response to receipt of a message without binding Document Object Model (DOM) elements.

10. The apparatus of claim 2, wherein the polymorphism module implements parametric polymorphism and subtype polymorphism.

11. The apparatus of claim 2, wherein the polymorphism module is configured to create schema-less data objects.

12. The apparatus of claim 11, wherein the schema-less data objects are JavaScript Object Notation (JSON) objects.

13. The apparatus of claim 2, wherein the polymorphism module implements an ignorant and apathetic approach to the structure of records.

14. The apparatus of claim 2, further comprising JavaScript extension engine configured to automatically generate HTML.

15. A system for extending JavaScript, the system comprising:

an electronic device comprising a non-transitory computer readable storage medium;

a web browser stored in a memory and operating on the electronic device and configured to access JavaScript code;

a JavaScript extension tool stored in the memory on the electronic device and configured to operate as an extension of a JavaScript environment by being interpreted and executed at run-time, the JavaScript extension tool comprising;

a multiple inheritance module comprising first JavaScript code to implement multiple inheritance by interpreting the first JavaScript code at run-time on the electronic device, wherein the multiple inheritance module is configured to create a subclass that inherits one or more behaviors from a plurality of objects passed as parameters to the subclass, and configured to resolve conflicts between inherited behaviors by allowing a newly inherited class to over-ride a function of the same name for a prior parent class;

a messaging module comprising second JavaScript code to implement messaging by interpreting the second JavaScript code at run-time on the electronic device, wherein the messaging module enables a central updater to query one or more applications to determine identity (ID) of data currently associated with each application, while the central updater has no knowledge of inner-working of the one or more applications; and

a polymorphism module comprising third JavaScript code to implement polymorphism by interpreting the third JavaScript code at run-time on the electronic device.

16. The system of claim 15, further comprising one or more web based applications.

17. The system of claim 15, further comprising one or more web based storage devices that are accessible by the electronic device.
