You can add a form onsubmit handler  something like    lt form onsubmit  return validate     gt    lt  form gt     lt script gt function validate         check if input is bigger than 3  var value   document getElementById  titleeee   value   if  value length  lt  3       return false     keep form from submitting         else form is good let it submit  of course you will      probably want to alert the user WHAT went wrong    return true    lt  script gt
