You probably want to use a regex like the one described here to check the format  When the form s submitted  run the following test on each field   var userinput     this  val    var pattern      b A-Z0-9   -    A-Z0-9 -     A-Z  2 4  b  i  if  pattern test userinput       alert  not a valid e-mail address
