seekTo Method

Locates a specified point on the element's segment timeline, including repetitions, and begins playing from that point.

Syntax

object.seekTo(iIteration, iSeconds)

Parameters

iIteration Required. Integer that specifies the repeatCount iteration at which to begin playing the element's timeline.
iSeconds Required. Integer that specifies the point in the element's segment timeline at which to start playing the element. Legal values range from 0 to segmentDur.

Return Value

No return value.

Remarks

If you attempt to seek to a time on an object that is not currently active, an error is generated. To prevent this, check the object's status using the isActive property.
Not all media types support seeking. In cases where seeking is not supported by the player, calls to seek methods are ignored.

Example

This example demonstrates how to use the seekTo property. Before validating and implementing the seekTo value, make sure the object is active, otherwise an error generates. In this example, if the object is not active the beginElement method is called to restart the object, followed by the seekTo method request.
