Works fine with newer browsers. Should be safe anyway. Either lenght is 1, then the loop is ok, or it's undefined (or 0) then we can check for checked directly.

+1, but could you please, while you're at it, rename the var "l" into "len"? I read "if (1)" (digit one) instead of "if (l)" (small letter L).
