I'm not too sure how to do this. I need to validate email addresses using regex with something like this:
[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+(?:[A-Z]{2}|com|org|net|edu|gov|mil|biz|info|mobi|name|aero|asia|jobs|museum)
Then I need to run this in a jQuery function like this:
$j("#fld_emailaddress").live('change',function() {
var emailaddress = $j("#fld_emailaddress").val();
// validation here?
if(emailaddress){}
// end validation
$j.ajax({
type: "POST",
url: "../ff-admin/ff-register/ff-user-check.php",
data: "fld_emailaddress="+ emailaddress,
success: function(msg)
{
if(msg == 'OK') {
$j("#fld_username").attr('disabled',false);
$j("#fld_password").attr('disabled',false);
$j("#cmd_register_submit").attr('disabled',false);
$j("#fld_emailaddress").removeClass('object_error'); // if necessary
$j("#fld_emailaddress").addClass("object_ok");
$j('#email_ac').html(' <img src="img/cool.png" align="absmiddle"> <font color="Green"> Your email <strong>'+ emailaddress+'</strong> is OK.</font> ');
} else {
$j("#fld_username").attr('disabled',true);
$j("#fld_password").attr('disabled',true);
$j("#cmd_register_submit").attr('disabled',true);
$j("#fld_emailaddress").removeClass('object_ok'); // if necessary
$j("#fld_emailaddress").addClass("object_error");
$j('#email_ac').html(msg);
}
}
});
});
Where does the validation go and what is the expression?
function isValidEmailAddress(emailAddress) {
var pattern = /^([a-z\d!#$%&'*+\-\/=?^_`{|}~\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]+(\.[a-z\d!#$%&'*+\-\/=?^_`{|}~\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]+)*|"((([ \t]*\r\n)?[ \t]+)?([\x01-\x08\x0b\x0c\x0e-\x1f\x7f\x21\x23-\x5b\x5d-\x7e\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]|\\[\x01-\x09\x0b\x0c\x0d-\x7f\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]))*(([ \t]*\r\n)?[ \t]+)?")@(([a-z\d\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]|[a-z\d\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF][a-z\d\-._~\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]*[a-z\d\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])\.)+([a-z\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]|[a-z\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF][a-z\d\-._~\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]*[a-z\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])\.?$/i;
return pattern.test(emailAddress);
}
if( !isValidEmailAddress( emailaddress ) ) { /* do stuff here */ }
