Abstract

An authoring tool can be used by an author, who may or may not have programming experience, to create complex input forms for the Internet. The authoring tool provides visual components that permit an author to build both the layout and functionality of the input form without writing any programming code. The author can select an input field to be inserted in the input form from a list of input types. The author can then customize the visual layout and appearance of the input fields and can incorporate dynamic behavior into the input form by associating events, actions and error checking with each input field. The authoring tool also provides a preview frame that interactively shows the author the appearance of the input form, as the author is building the input form. Finally, once the author is satisfied with the input form that is being created, the author can use the authoring tool to generate a file or web page that is executable on the client side by any web browser.

2. The method of claim 1 further comprising the steps of:

incorporating each inserted field into the visual representation of the web page, the incorporating of each inserted field includes incorporating the customizations to the visual appearance of the inserted field and incorporating the customizations to the dynamic behavior of the inserted field; and

displaying an updated visual representation of the web page after the step of incorporating each inserted field into the visual representation of the web page.

3. The method of claim 1 wherein said step of customizing dynamic behavior of the inserted field comprises the steps of:

providing a visual editor for defining properties of the inserted field in response to the selection of at least one particular field type of the plurality of field types;

providing a visual editor for defining error conditions for the inserted field in response to the selection of at least one particular field type of the plurality of field types; and

providing a visual editor for defining control operations for the inserted field in response to the selection of at least one particular field type of the plurality of field types.

4. The method of claim 3 wherein said step of customizing dynamic behavior of the inserted field further comprises the step of defining a plurality of states for the inserted field with the visual editor for defining properties, each state of the plurality of states having a corresponding set of properties for the inserted field.

5. The method of claim 3 wherein said step of customizing dynamic behavior of the inserted field further comprises the steps of:

defining dependencies between the inserted field and other inserted fields with the visual editor for defining control operations; and

defining events for the inserted field and defining corresponding actions for each defined event with the visual editor for defining control operations.

6. The method of claim 3 wherein said step of customizing dynamic behavior of the inserted field further comprises the step of defining at least one error condition for the inserted field with the visual editor for defining error conditions.

7. The method of claim 1 wherein said step of customizing a visual appearance of the inserted field further comprises the steps of:

customizing the location of the inserted field in the web page; and

customizing the size of the inserted field in the web page.

8. The method of claim 1 wherein said step of generating program code, in a single file, executable by a web browser comprises the steps of:

instantiating an object for each inserted field, each object being instantiated from a corresponding field type of the inserted field and including the customizations to the visual appearance of the inserted field and the customizations to the dynamic behavior of the inserted field;

providing a control engine to execute each instantiated object; and

generating at least one of HTML code and JavaScript code to implement each instantiated object, the control engine and the plurality of field types.

9. A system to develop and provide a web application executable by a web browser, the system comprising:

a computer, said computer comprising a storage device and a processor;

an authoring tool, said authoring tool being stored on said computer, said authoring tool being configured for use by an author to generate a web application, said authoring tool comprising a visual development environment to generate a visual appearance and dynamic behavior for fields of said web application and a code generator to generate program code for said web application to implement said generated visual appearance and dynamic behavior of said fields of said web application in a single file executable by a web browser; and

at least one server communicating with said authoring tool, said at least one server comprising means for providing access to said generated program code for said web application to an end-user having a web browser.

10. The system of claim 9 wherein said visual development environment further comprises:

means for displaying a representation of a current state of said web application;

means for selecting a field from a plurality of field types for inclusion in said web application; and

a plurality of visual editors to customize a visual appearance and dynamic behavior of said selected field, said plurality of visual editors to customize said selected field is dependent on said field type of said selected field.

11. The system of claim 10 further comprising means for incorporating each selected field customized with said plurality of visual editors into said representation of said web application displayed by said means for displaying.

12. The system of claim 10 wherein said plurality of visual editors comprises:

a visual editor for defining properties of said selected field;

a visual editor for defining error conditions for said selected field; and

a visual editor for defining control operations for said selected field.

13. The system of claim 12 wherein:

said visual editor for defining properties of said selected field comprises means for defining a plurality of states for said selected field, each state of said plurality of states has a corresponding set of properties for said selected field;

said visual editor for defining control operation for said selected field comprises;
