If you type   if   number value length   10            It will sure work because the value is the quantity which will be driven from the object

If number is your form element  then its length will be undefined since elements don t have length  You want  if  number value length    10            An easier way to do all the validation at once  though  would be with a regex   var val   number value if     d 10    test val            value is ok  use it   else       alert  Invalid number  must be ten digits       number focus       return false      d means  digit   and  10  means  ten times   The   and   anchor it to the start and end  so something like asdf1234567890asdf does not match
