The title plus the following example are self-explanatory of what I don't achieve :-) The idea is to replace something + counter in order to make it work.

      for (var counter = 1; counter <= 6; counter++) {
        var something + counter = $('element' + counter);
        (something + counter).removeAttribute('class');
      }

• 1 Why do you need to create a variable in the loop at all? Can you not just do $('element' + counter).removeAttribute('class');? – James Allardice Commented Aug 23, 2011 at 13:19

You could create an array, but much more simply:

  for (var counter = 1; counter <= 6; counter++) {
    $('element' + counter).removeAttribute('class');
  } 

Just do:

for (var counter = 1; counter <= 6; counter++) {
    $('element' + counter).removeAttribute('class');
}

Unless you wanted to store it outside of the loop, in which case use an array.

Use an array.

var something = [];
for (var counter = 1; counter <= 6; counter++) {
    something[counter] = $('element' + counter);
    something[counter].removeAttribute('class');
}

Why can't you just get rid of the var altogether??

for (var counter = 1; counter <= 6; counter++) {
    $('element' + counter).removeAttribute('class');
}

  for (var counter = 1; counter <= 6; counter++) {
    window[something + counter] = $('element' + counter);
    window[something + counter].removeAttribute('class');
  } 

after that there will be a set of fields in window object, named something1, something2 etc (if something == "something", of course)
