Event: returnValue property
Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
Note: This feature is available in Web Workers.
The Event property
returnValue indicates whether the default action for
this event has been prevented or not.
It is set to true by
default, allowing the default action to occur. Setting this property to
false prevents the default action.
Note:
While returnValue has been adopted into the DOM
standard, it is present primarily to support existing code. Use
preventDefault(), and
defaultPrevented instead of this historical
property.
Value
A boolean value which is true if the event has not been
canceled; otherwise, if the event has been canceled or the default has been prevented,
the value is false.
The value of returnValue is the opposite of the value returned by
defaultPrevented.
