Flex target property example

     

In coding the below flex application we have use an event object property  target . We also have another event object property currentTarget. 
These properties enables the programmer to  track the event of which the object is made, during the event's propagating process. Properties target and currentTarget differ in their targeting jobs.  target property may dispatch the event to a component or component's sub component, whereas currentTarget will target the event to a particular node in which the event listener (function in which the event object is made) is called or tested.

Syntax for using these object properties
 
event.target.label
 
event.currentTarget.label
