Abstract

A system for extending interactivity of a presentation markup language is provided. The system comprises a collection of designated elements, and a collection of associated instructions for performing functions on elements in the document object model. Each designated element comprises a namespace, and attributes for describing features of the designated element. The instructions associated with the designated elements.

2. The system as claimed in claim 1, further comprising an initialization function for directing the processing one or more designated elements in the document object model, having instructions for traversing each node in the document object model and for searching and calling functions associated with designated elements having names following a predetermined naming convention.

3. The system as claimed in claim 1, wherein the designated element is associated with an extensible markup language element.

4. The system as claimed in claim 1, further comprising:

a collection of designated attributes applied to one or more of the document object model elements for applying passive behavior to objects in the web application; and

a collection of associated instructions for performing functions associated with the designated attributes.

5. The system as claimed in claim 4, wherein the collection of designated attributes comprises one or more of:

a ‘

drag’

attribute for specifying whether the element is movable by clicking and dragging it with the mouse;

a ‘

pan’

attribute for specifying whether the element is immune to panning;

a ‘

zoom’

attribute for specifying whether the element is immune to zooming;

a ‘

selected’

attribute for specifying whether the element has been selected; and

a ‘

selectionGroup’

attribute for specifying an ‘

id’

attribute of a <

selection>

element that this element is associated with.

6. The system as claimed in claim 1, wherein the collection of designated elements comprises one or more of:

flow control elements for controlling statement flow of the web application;

coordinate mapping elements for manipulating coordinates of objects in the web application;

behavior elements for manipulating viewer behavior with respect to the web application;

a focus element for selecting a group of elements in the web application; and

a constraint element for constraining manipulable attributes of an element in a web application.

7. The system as claimed in claim 6, wherein the flow control elements comprise one or more of:

an if element for defining a simple conditional statement which, when it evaluates to true, results in its child elements being executed or rendered;

a switch element for defining a conditional statement, and for comparing one value to other values defined in child <

case>

elements;

a case element for defining the value to compare to a ‘

value’

attribute of the switch element;

a default element for containing action elements to be executed; and

a loop element for defining a repeated sequence of actions.

8. The system as claimed in claim 6, wherein the coordinate mapping elements comprise one or more of:

a mousePosition element for defining a container for holding current mouse coordinates;

a mapCoords element for defining an object used for mapping coordinates in one space to another space, via a polynomial transformation, whose coefficients are determined by the coordinates of point-pairs;

a pointPair element for defining x-y coordinates for a same location in two different coordinate spaces; and

a mapProj element for defining an object used for mapping coordinates in one projection system to another.

9. The system as claimed in claim 6, wherein the viewer behavior elements comprise one or more of:

a zoom element for scaling a document by a factor;

a pan element for translating a document by an amount; and

a playSound element for playing an audio file.

10. A method of extending interactivity of presentation markup languages, the method comprising one or more of the following:

controlling statement flow of a web application, the method comprising the steps of;

searching for a flow control element in a document object model of the web application;

generating a function name associated with the flow control element;

calling the generated function name; and

processing child elements of the flow control element;

coordinate mapping of a web application, the method comprising the steps of;

searching for a coordinate mapping element in a document object model of the web application;

generating a function name associated with the coordinate mapping element; and

calling the generated function name;

manipulating viewer behavior with respect to a web application, the method comprising the steps of;

searching for a viewer behavior element in a document object model of the web application;

generating a function name associated with the viewer behavior element; and

calling the generated function name;

focussing a group of elements in a web application, the method comprising the steps of;

searching for a focus element in a document object model of the web application;

generating a function name associated with the focus element; and

calling the generated function name;

constraining manipulable attributes of an element in a web application, the method comprising the steps of;

searching for a constraint element in a document object model of the web application;

generating a function name associated with the constraint element; and

calling the generated function name; and

applying passive behavior to an element of a web application, the method comprising the steps of;

searching for a designated attribute of the element in a document object model of the web application;

generating a function name associated with the designated attribute; and

calling the generated function name.

11. A method of extending interactivity of a presentation markup language, the method comprising the steps of:

searching for a designated control element in a document object model; and

calling a function associated with the designated control element.

12. The method as claimed in claim 11, wherein the step of searching includes the steps of:

traversing each node in the document object model; and

determining whether an element has a name which follows a designated naming convention.

13. The method as claimed in claim 11, wherein the step of calling a function includes the steps of:

dynamically generating a function name associated with the designated element;

passing an object associated with the designated element as a parameter of the generated function;

retrieving the attributes of the object; and

performing a function stored in memory having the generated function name.

14. The method as claimed in claim 13, wherein the step of dynamically generating includes the steps of:

determining if the name of the designated element contains a designated prefix;

generating a function name comprising of the name of the designated element;

assigning an object associated with the designated element as the parameter of the function; and

assigning predetermined instructions of the designated element as steps for the function to perform.

15. The method as claimed in claim 11, wherein the step of calling a function includes the steps of:
