[Javascript] dynamic variables names

[Marcelo Simon]

Thanks for the answers, but they didn't solve my problem.

I didn't post the entire function, and that's why I think you say that I don't have a dynamic variable name. ( or maybe I'm wrong ), here's the function

function note(number){
 for ( var i=1; i < 6; i++){
  if ( i <= number ){
  alert(['nt_0'+i].src); // it's tracing undefined
   ['nt_o'+i].src = '../_img/1_note_0'+i+'_on.gif';
  } else {
   ['nt_o'+i].src = '../_img/1_note_0'+i+'_off.gif';
  }
 }
}

what I'm trying to accomplish, is to change some images from 1 to i based on the number I pass to the function (ie. if I pass 3, I want images 1,2 and 3 to be on and 4 and 5 to be off ), so if someone has a different approach to this please share.

Thanks again
Marcelo Simon

  Do you have a dynamic variable name? I would never use a 
  dynamic variable to be honest with you - or at least haven't ever 
  found the need for one yet, but from the looks of it below, you 
  don't have a dynamic variable, but rather you're trying to build 
  a reference to an image dynamically.

  To do that, use the document.images collection and 
  build your string when targeting a specific element in that 
  collection:

  document.images["nt_o" + i].src = "path/to/image.gif"

  That's not a dynamic variable name - just so you're aware.

    Hi list, 

    It's me again, and I need some help again please.

    how can I use dynamic variables name in JS ?

    I mean, how do I evaluate the 2 parts so they work ?

    if ( i <= number ){
       ['nt_o'+i].src = '../_img/1_nota_0'+i+'_on.gif';
    }

    thanks in advance
