Flash ActionScript2 loop

I have 180 buttons in one Flash file and for all buttons I need a roll over and a click event, so the code I`m using is:

button1.onRollOver = function() { //on roll over change button color as white
  var color = new Color(button1); 
  color.setRGB("0xFFFFFF"); 
};
button1.onRollOut = function() { //on roll out reset button color to it`s default
  resetColorFunction(); 
};
button1.onPress = function() { //on click/press runs javascript function in page
  getURL("javascript:ButtonPress('button1');"); 
};

The problem is that I have 180 buttons, so I`m copying this code to each button, button1, button2, button3, button4 ...etc until button180.

Is there any way to loop through all buttons with one simple code, function.

Thank you

You can use a for-in loop in the stage or any container.

for (var item in this) {
    if (this[item] instanceof Button) { //-- Use the most relevent class for abstraction
        var btn = this[item];
        trace ("Button: " + btn._name + " btn._x:" + btn._x + " a: " + btn._alpha);

        //-- add Logic for event handlers.
    }
}

You can use eval in Actionscript 2 to get all your buttons tagged with minimal effort.

buttonRollOver = function() { ... };
buttonRollOut = function() { ... };
buttonPressed = function() { ... };

for (var i=1; i<181; i++)
{
   eval("button"+i).onRollOver = buttonRollOver;
   eval("button"+i).onRollOut = buttonRollOut;
   eval("button"+i).onPress = buttonPressed;
}

And there you have it all nice and fast.

You can add all of these buttons to a collection of some sort, then loop through all of the elements and add the event handlers. Something like this:

var buttons:ArrayCollection = new ArrayCollection();
var button1:Button = new Button();
var button2:Button = new Button();
// some more buttons creation ...

and each time you create a button, you simply add it to the buttons collection.

buttons.addItem(button1);
buttons.addItem(button2);
// etc

Finaly you just loop through all the buttons and add the required event handlers.

for each (var button:Button in buttons)
{
    button.onRollOver = function() { // handle RollOver };
    button.onRollOut  = function() { // handle RollOut };
    button.onClick    = function() { // handle Click };
}

To use an array you can do the following:

var buttons:Array = [];
buttons.push(button1);
// add all other buttons..

for (var i:uint = 0; i < buttons.length; i++)
{
    var button:Button = Button(buttons[i]);
    button.onRollOver = function() { // handle RollOver };
    button.onRollOut  = function() { // handle RollOut };
    button.onClick    = function() { // handle Click };
}
