Question

Passing extra argument in event listener?

Is this possible?  I have one event handler for several object's events.  I would like to pass a value through to the function from the event listener:






 function chkEmpty(event:Event){
               if(event.currentTarget.text==""){
                    thisIsBitIWantToBeAbleChange.text = "You haven't entered anything in the box, please try again"
                    hisIsBitIWantToBeAbleChange.setTextFormat(validate_frmt);
               }
          }

Could I give the event.currentTarget a value that I could test for? So if the value is 1, I effect output1_txt, if 2, output2_txt, etc etc. If so, are there customisable values that I could use that wouldn't do anything to the display object,?

Sorry, I can't work the code highlighting things on here!

Here is my problem again:

Is this possible?  I have one event handler for several object's events.  I would like to pass a value through to the function from the event listener:

function chkEmpty(event:Event){
               if(event.currentTarget.text==" "){
                    thisIsBitIWantToBeAbleChange.text = "You haven't entered anything in the box, please try again"
                    hisIsBitIWantToBeAbleChange.setTextFormat(validate_frmt);
               }
          }

The event listener is on various textInput boxes.  It is called when it loses focus.

Could I give the event.currentTarget a value that I could test for? So if the value is 1, I effect output1_txt, if 2, output2_txt, etc etc. If so, are there customisable values that I could use that wouldn't do anything to the display object,?

Is this what you After?  you can use the propertist of your  event.target to make decisions

btn1.addEventListener(MouseEvent.CLICK,chkEmpty);
btn2.addEventListener(MouseEvent.CLICK,chkEmpty);
btn3.addEventListener(MouseEvent.CLICK,chkEmpty);
function chkEmpty(evt:Event) {


     if (evt.currentTarget.name=="btn1") {


          trace( "You haven't entered anything in the box, please try again");
     } else if (evt.currentTarget.name != "btn1") {
          trace( evt.currentTarget.name);
     }
}

does name refer to the var name the object is contained?
