Hello all,
I’m trying to do some simple email validation. I have the following javascript:
[CODE]// Email Validation Javascript
function validate_email(addr,man,db)
{
if (addr == ” && man) {
if (db) alert(’email address is mandatory’);
return false;
}
if (addr == ”) return true;
var invalidChars = ‘/’\ “;:?!()[]{}^|’;
for (i=0; i<invalidChars.length; i++) {
if (addr.indexOf(invalidChars.charAt(i),0) > -1) {
if (db) alert(’email address contains invalid characters’);
return false;
}
}
for (i=0; i<addr.length; i++) {
if (addr.charCodeAt(i)>127) {
if (db) alert(“email address contains non ascii characters.”);
return false;
}
}
var atPos = addr.indexOf(‘@’,0);
if (atPos == -1) {
if (db) alert(’email address must contain an @’);
return false;
}
if (atPos == 0) {
if (db) alert(’email address must not start with @’);
return false;
}
if (addr.indexOf(‘@’, atPos + 1) > – 1) {
if (db) alert(’email address must contain only one @’);
return false;
}
if (addr.indexOf(‘.’, atPos) == -1) {
if (db) alert(’email address must contain a period in the domain name’);
return false;
}
if (addr.indexOf(‘@.’,0) != -1) {
if (db) alert(‘period must not immediately follow @ in email address’);
return false;
}
if (addr.indexOf(‘.@’,0) != -1){
if (db) alert(‘period must not immediately precede @ in email address’);
return false;
}
if (addr.indexOf(‘..’,0) != -1) {
if (db) alert(‘two periods must not be adjacent in email address’);
return false;
}
var suffix = addr.substring(addr.lastIndexOf(‘.’)+1);
if (suffix.length != 2 && suffix != ‘com’ && suffix != ‘net’ && suffix != ‘org’ && suffix != ‘edu’ && suffix != ‘int’ && suffix != ‘mil’ && suffix != ‘gov’ & suffix != ‘arpa’ && suffix != ‘biz’ && suffix != ‘aero’ && suffix != ‘name’ && suffix != ‘coop’ && suffix != ‘info’ && suffix != ‘pro’ && suffix != ‘museum’) {
if (db) alert(‘invalid primary domain in email address’);
return false;
}
return true;
}
and the following form:
[CODE]<form action=”contact_us_summary.php” method=”post” name=”email” onsubmit=”return validate_email(document.getElementById(’email_address’).value, 1, 1);”>
When the form is submitted I get the correct error message, however the form is still submitted!
If someone could help me spot my mistake I would be most grateful!
Many Thanks,
