[Javascript] dynamic variables names

[Chris Tifer]

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
