I have no idea what actionscript does, but how about an array?

Code:

var arr
= new Array("firstvideo.jpg", "secondvideo.jpg");
var idx = 0;

When you need the file, just use its index pos.

Code:

 
 placeholder.loadMovie(arr[idx]);
   idx++;

Simple Javascript variable problem

43970 — 2009-06-18T09:17:56+01:00

Sorry for actually asking this as it's a ridiculously simple problem, but I'm brand new to JavaScript.
I know how to do what I want to in ActionScript, but I'm not sure what the syntax is to accomplish it in JavaScript.
In ActionScript I've written a chunk of code that looks something like this:

---------------

var currentNumber = 1;
var picture1Video = " firstVideo.jpg";
var picture2Video = " secondVideo.jpg";

placeHolder1.loadMovie(this["picture"+(currentNumber)+"video"])

currentNumber++;

placeHolder2.loadMovie(this["picture"+(currentNumber)+"video"])

---------------

So basically I'm incrimenting currentNumber to change what variable placeHolder1 and placeHolder2 are looking at.

How do I write that in Javascript, so that a variable name being called is made up of a string and the contents of another variable, like ["picture"+currentNumber+"video"] ?

Cheers for any help!
