Event: returnValue property

Deprecated

Avoid using this feature in new projects. This feature may be a candidate for removal from web standards or browsers.

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.
