Abstract

Properties defining modes for handling user events such as cursor events and touch events on a computing device such as a touchscreen device are provided. One property determines, for an entire webpage or for elements thereof, whether received cursor events should be processed in accordance with default handling routines configured in the browser environment, or passed for handling by an event handler defined for the element. Another property determines, for the entire webpage or elements thereof, whether received touch events should be processed in accordance with default handling routines, passed for handling by an event handler, or converted to cursor events or mouse events for handling by an event handler.

Claims

1. A method, comprising:

receiving a webpage at an electronic device;

determining whether a touch event handling property is defined for the webpage;

receiving a touch event at the electronic device while the webpage is displayed in a browser environment executing on the electronic device;

when the touch event handling property is not defined for the webpage, or when the touch event handling property is defined for the webpage and is assigned a value indicating that default handling functions included with the browser environment are permitted,

if a default handling function is available to handle the touch event, handling the touch event with the default handling function;

if a default handling function is not available to handle the touch event and a script or other webpage-defined event handler is provided with the webpage to handle the touch event, executing the script or other webpage-defined event handler to handle the touch event;

when the touch event handling property is defined for the webpage and is assigned a value indicating that default handling functions are not permitted, executing the script or other webpage-defined event handler to handle the touch event, if the script or other webpage-defined event handler is provided for the webpage.

2. The method of claim 1, further comprising, when the first touch event handling property is defined for the webpage and is assigned a value indicating that the touch event is to be converted to a mouse event:

converting the touch event to a corresponding mouse event when no script or other webpage-defined event handler is provided with the webpage to handle the touch event.

3. The method of claim 1, further comprising, when the first touch event handling property is defined for the webpage and is assigned a value indicating that the touch event is to be converted to a mouse event, and when a script or other webpage-defined event handler is provided with the webpage to handle the touch event:

executing the script or other webpage-defined event handler to handle the touch event.

4. The method of claim 1, wherein the value indicating that default handling functions included with the browser environment are permitted indicates that default handling functions in respect of any touch events associated default handling functions included with the browser environment are permitted.

5. The method of claim 1, wherein the script or other webpage-defined event handler is received with the webpage.

6. The method of claim 1, wherein the default handling functions included with the browser environment comprise invocation of an operating system API.

7. The method of claim 1, wherein the first touch event handling property is defined for the entire webpage.

8. The method of claim 1, wherein the first touch event handling property is defined for an element type within the webpage.

9. The method of claim 1, wherein the electronic device comprises a touchscreen display.

10. The method of claim 1, wherein a script is provided to handle the touch event, the script being provided separately from the webpage.

11. The method of claim 1, wherein the electronic device comprises a tablet or smartphone.

12. An electronic device, including:

a touchscreen display interface for receiving touch events; and

a processor in communication with the touchscreen display interface, the processor being configured to enable;

receiving a webpage;

determining whether a first touch event handling property is defined for the webpage;

receiving a touch event while the webpage is displayed in a browser environment executing on the electronic device;

when the first touch event handling property is not defined for the webpage, or when the first touch event handling property is defined for the webpage and is assigned a value indicating that default handling functions included with the browser environment are permitted,

if a default handling function is available to handle the touch event, handle the touch event with the default handling function;

if a default handling function is not available to handle the touch event and a script or other webpage-defined event handler is provided with the webpage to handle the touch event, execute the script or other webpage-defined event handler to handle the touch event;

when the first touch event handling property is defined for the webpage and is assigned a value indicating that default handling functions are not permitted, execute the script or other webpage-defined event handler to handle the touch event, if the script or other webpage-defined event handler is provided for the webpage.

13. The electronic device of claim 12, wherein the processor is further configured to, when the first touch event handling property is defined for the webpage and is assigned a value indicating that the touch event is to be converted to a mouse event:

convert the touch event to a corresponding mouse event when no script or other webpage-defined event handler is provided with the webpage to handle the touch event.

14. The electronic device of claim 12, wherein the processor is further configured to, when the first touch event handling property is defined for the webpage and is assigned a value indicating that the touch event is to be converted to a mouse event, and when a script or other webpage-defined event handler is provided with the webpage to handle the touch event:

execute the script or other webpage-defined event handler to handle the touch event.

15. The electronic device of claim 12, wherein the value indicating that default handling functions included with the browser environment are permitted indicates that default handling functions in respect of any touch events associated default handling functions included with the browser environment are permitted.

16. The electronic device of claim 12, wherein the script or other webpage-defined event handler is received with the webpage.

17. The electronic device of claim 12, wherein the default handling functions included with the browser environment comprise invocation of an operating system API.

18. The electronic device of claim 12, wherein the first touch event handling property is defined for the entire webpage.

19. The electronic device of claim 12, wherein the first touch event handling property is defined for an element type within the webpage.

20. The electronic device of claim 12, wherein a script is provided to handle the touch event, the script being provided separately from the webpage.
