Automatically assign variable names

[Nugget89]

Hi, I'm working on a project using google maps. For part of it the user must enter coordinates and click a button in order to add a marker to a map. The code I have written so far allows this to be done once:

play_btn2.addEventListener(MouseEvent.MOUSE_DOWN, submitdata);
function submitdata(e:Event){
var marker9:Marker = new Marker(
new LatLng(Number(myTextBox1.text), Number(myTextBox2.text)),
new MarkerOptions({
radius: 8,
hasShadow: true

})
);
gotoAndStop("Home");
map.addOverlay(marker9);
}


As it is the only one marker can be added as it keeps getting replaced. I want to make it so that the variable name changes each time a marker is to be added. I've made a few attempts using i++ but I'm not really sure what I'm doing.
Anyone know how I can get this working?

There are a couple of ways to do this, but generally I use an array to store my different items. This is what I mean.

var markerArr:Array = new Array();


play_btn2.addEventListener(MouseEvent.MOUSE_DOWN, submitdata);

function submitdata(e:Event){
    var tempMarker:Marker = new Marker(
                    new LatLng(Number(myTextBox1.text), Number(myTextBox2.text)),
                    new MarkerOptions({ radius: 8, hasShadow: true})
                                    );
    markerArr.push(tempMarker);
    gotoAndStop("Home");
    map.addOverlay(markerArr[markerArr.length-1]);
} 

Of course you can get a dynamic class with a new name and then load the Marker class into it. I find that easier and allows me to track ALL of my similar objects.

Hi, thanks for the reply.
I used your code and it works perfectly if the input boxes and map are on the same page but I have them on different pages. This is the code for when the user clicks into the page to input the values.

sounds_btn.addEventListener(MouseEvent.CLICK, goSounds);
function goSounds (e:MouseEvent):void{
gotoAndStop("Sounds");
    removeChild(aura);
    removeChild(volumeslider);
    removeChild(map);
    removeChild(circle);
    addEventListener(Event.ENTER_FRAME, removecircle);
    
    addChild(myTextBox1);
    addChild(myTextBox2);
    addChild(myTextBox3);
    addChild(myTextBox4);

var markerArr:Array = new Array();

play_btn2.addEventListener(MouseEvent.MOUSE_DOWN, submitdata);

function submitdata(e:Event){
    var tempMarker:Marker = new Marker(
    new LatLng(Number(myTextBox1.text), Number(myTextBox2.text)),
    new MarkerOptions({ radius: 8, hasShadow: true})
                                    );
    markerArr.push(tempMarker);
    gotoAndStop("Home");
    map.addOverlay(markerArr[markerArr.length-1]);
} 

I'm having problems placing this code anywhere else.
Any idea what I can do to get this working?
