Plugin: jQuery.event.special.touch
Description: Bind special pinch event on touch interaction.
-
.on( 'touchpinch', ... )
version added: 1.3
This .on()
implements a simple bind to the touchpinch
interaction.
The touchpinch
event fires while the user drag together / apart two fingers.
The recieved event object on touchzoom
includes advanced properties:
- event.pinchState A value which represents the current pinch status (start / while / end).
- event.pinchDeltaT Milliseconds between current and previous drag event state.
- event.pinchDelta A float value which represents the diagonal pixel distance between the last and current distance of the fingers.
- event.pinchDeltaX A float value which represents the pixel distance between the last and current distance of the fingers on the x-axis.
- event.pinchDeltaY A float value which represents the pixel distance between the last and current distance of the fingers on the y-axis.
See the .on() and .off() method references for a way to bind/unbind event handlers.
The touchpinch
special event was replaced by the touchpinch
event in version 1.3.
