seekToFrame Method

Locates a specified frame in the object.

Syntax

object.seekToFrame(iFrame)

Parameters

iFrame Required. Integer that specifies a frame in the object.

Return Value

No return value.

Remarks

If you attempt to call the seekToFrame method 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 seekToFrame property. Before validating and implementing the seekToFrame value, make sure the object is active to avoid generating an error. In this example, if the object is not active the beginElement method is called to restart the object, followed by the seekToFrame method call.
