Creating function in a loop

Question

hello --
my problem is that i am dynamically creating a bunch of
buttons in a loop, and want to include a different "onRollOver"
function for each button. However, the variables I am setting in
the functions are all being overwritten with the value from the
last pass through the loop. How can i generate a different body of
the function for each button that I'm generating?
my code:
var dataindex=0;
[while loop]
var bname = "instbut_"+dataindex;
var button = container.createEmptyMovieClip(bname,
100+dataindex);
container[bname].onRollOver = function() { trace("my button
name is "+bname); }
dataindex++;
when this runs, it correctly generates four buttons -- but
when i roll over each, "bname" is always equal to "instbut_3". how
can i force it to generate four separate functions, instead of one
single one referenced by all the buttons together?
thanks for any tips!

Answer 1

var dataindex=0;
[while loop]
var bname = "instbut_"+dataindex;
var button = container.createEmptyMovieClip(bname,
100+dataindex);
button.myName = bname;
container[bname].onRollOver = function() { trace("my button
name is "+this.myName); }
dataindex++;
By the way, you could use this._name instead, but for other
variables, give the value you need before writing the event
handler, and then target the values with this.
