That doesn t work because  judging by the rest of the code  the initial value of the text input is  Default text  - which is more than one character  and so your if condition is  always true   The simplest way to make it work  it seems to me  is to account for this case       var value     this  val        if   value length  gt  0  amp  amp  value     Default text

If you mean that you want to enable the submit after the user has typed at least one character  then you need to attach a key event that will check it for you   Something like       fbss   keypress function         if   this  val   length  gt  1                Enable submit button       else               Disable submit button
