</script>I have downloaded this script from somewhere and tried embedding this in my login.php. IT WORKS. But when i tried saving it as validator.js inside the folder script and called it like:
HTML:
<script type="text/javascript" src='script/validate.js'></script>and in my form:
HTML:
<form method = 'POST' action = 'session2.php' onsubmit='return check(this)'>But it didn't work. Is there something wrong of how i called it? Because there is no error that appear, but the javascript doesn't do anything.
