Ans:
When event are triggered there are three phase whixh occured in the following order.
1. Captupring phase: In the capturing phase, Flex examines an event target?s ancestors in the display list to see which ones are registered as a listener for the event.
2. Targeting phase: In the targeting phase, Flex invokes the event dispatcher?s listeners. No other nodes on the display list are examined for event listeners.
3. Bubbling phase: In the bubbling phase, Flex examines an event?s ancestors for event listeners. Flex starts with the dispatcher?s immediate ancestor and continues up the display list to the root ancestor. This is the reverse of the capturing phase.
