onRollOver = function() --> return dynamic button name

[alex8735]

I've got a set of dynamically created listElements wich are Buttons. When I roll over them I want them to trace thier names(numbers). The following script doesn't work, the last value of "i" is alway returned instead of the number corresponding to the aktual listElement. Any ideas??

thx Alex

this.onEnterFrame = function(){
  for(i=0;i<numElem;i++){
    this["listElement"+i].onRollOver = function(){
      trace("listElement"+i);
    }
  }
}

Try:

this.onEnterFrame = function(){
for(i=0;i<numElem;i++){
this["listElement"+i].onRollOver = function(){
trace(this._name);
}
}
}

Not at all surprising when you think of the scope of each variable. i is defined on the time line and is not local, so all functions point to the same value ... which has been reset in making all the list elements.
However, given that you have already named the list elements with the index number, why not use that instead.

code:

---

this.onEnterFrame = function(){ 

  for(i=0;i<numElem;i++){ 

    this["listElement"+i].onRollOver = function(){ 

      var n = this._name;

      var ind = n.substr("listelement".length,n.length)

      trace(n +" has index number "+ind); 

    } 

  } 

}

---

The alternative, is to set a variable in each list element as you make them.

Thanks

I tried almost everything and the solution is so simple ;-)))
