Syntax

Scripting [ sMode = ] object.updateMode

Possible Values

sMode String that specifies or receives one of the following values.
Auto
Automatically assigns a new value to the property being set and updates the object. The property maintains the repeatCount value and the segmentTime value of the element, and is similar to a reset followed by a seekTo for the object.
Reset
Default. Resets the node to its initial state after the change.

The property is read/write. The property has a default value of Reset.

Remarks

updateMode was introduced in Microsoft Internet Explorer 6.

The beginElement method called on an object with updateMode set to Reset is ignored.

The following table describes which attribute or property can be updated and the effect that the updateMode property has on the atribute or property.
