syntax question to catch dynamically generated divs in a page

[jonavanmona]

i've got a -maybe dumb- question since i've never had a single js lesson :)

i want to catch some divs in a page, at first i got all the names of them from a db, but now they are dynamicly generated.
so.. i couldnt use php anymore.. so.. this is what i came up with:

 if (obj.name.match('resize'))
    {
    instance = str.replace(/resize/,"");
 
    elements.q+instance+.resizeTo(dd.obj.x-elements.q+instance+.x+12, ((obj.y+12)-dd.elements.q+instance+.y));
        elements.opt+instance+.moveTo(dd.obj.x-24, dd.obj.y);
        elements.movemove+instance+.moveTo(dd.obj.x-12, dd.obj.y);
        }

well, this doesnt work.
example:
object name is "resize1"
i strip resize
and i want to get:
elements.movemove1.moveTo(dd.obj.x-12, dd.obj.y);

you know what i mean :)

Assuming these are the IDs, use document.getElementById:

document.getElementById("q"+instance)...
