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:

detecting a first touch event associated with a webpage rendered for display in a browser environment, the browser environment implementing a plurality of functions for handling a set of touch events;

when a first touch event handling property is defined for said webpage, the first touch event handling property defining a first plurality of touch events of the set of touch events for handling by a script provided for said webpage, executing said script to handle said first touch event when said first touch event is comprised in the first plurality of touch events; and

when the first touch event handling property is not so defined, the browser environment handling the first touch event using one of the plurality of functions.

2. The method of claim 1, further comprising:

when a second touch event handling property is defined for said webpage, the second touch event handling property defining a second plurality of touch events of the set of touch events for handling by said script and defining a third plurality of touch events for conversion to a mouse event,

executing said script to handle said first touch event when said first touch event is comprised in the second plurality of touch events; and

converting said first touch event to a corresponding mouse event when said first touch event is comprised in the third plurality of touch events.

3. The method of claim 2, wherein the first touch event handling property comprises a defined property set to a first value, and the second touch event handling property comprises the same defined property set to a second value.

4. The method of claim 1, wherein the first plurality of touch events defined by the first touch event handling property comprises the entire set of touch events.

5. The method of claim 1, wherein the second plurality of touch events defined by the second touch event handling property comprises a subset of the first plurality of touch events.
