Sprawdzanie poprawności adresów e-mail przy użyciu jQuery i regex

Question

Sprawdzanie poprawności adresów e-mail przy użyciu jQuery i regex

Nie wiem, jak to zrobić. Muszę zweryfikować adresy e-mail używając regex z czymś takim:

[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)

Następnie muszę uruchomić to w funkcji jQuery jak Ta:

$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('&nbsp;<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);
            }
        }
     });
});

Gdzie przebiega Walidacja i jakie jest wyrażenie?

To jest moje rozwiązanie:

function isValidEmailAddress(emailAddress) {
    var pattern = new RegExp(/^[+a-zA-Z0-9._-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$/i);
    // alert( pattern.test(emailAddress) );
    return pattern.test(emailAddress);
};

~~znalazłem to wyrażenie regularne tutaj: http://mdskinner.com/code/email-regex-and-validation-jquery~~

                }

Lolz this is much better

    function isValidEmailAddress(emailAddress) {
        var pattern = new RegExp(/^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/);
        return pattern.test(emailAddress);
    };

Polecam użycie wtyczki jQuery dla Verimail.js .

Dlaczego?

IANA TLD validation
Walidacja składni (zgodnie z RFC 822)
sugestia ortograficzna dla najczęściej używanych domen TLD i e-mail
Zablokuj tymczasowe domeny kont e-mail, takie jak mailinator.com

Jak?

Include verimail.jquery.js na swojej stronie i użyj funkcji:

$("input#email-address").verimail({
    messageElement: "p#status-message"
});

Jeśli masz formularz i chcesz zweryfikować wiadomość e-mail podczas przesyłania, możesz użyć funkcji getVerimailStatus:

if($("input#email-address").getVerimailStatus() < 0){
    // Invalid email
}else{
    // Valid email
}

Javascript:

var pattern = new RegExp("^[_A-Za-z0-9-]+(\\.[_A-Za-z0-9-]+)*@[A-Za-z0-9]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})$");
var result = pattern .test(str);

Wyrażenie regularne nie jest dozwolone dla:

[email protected]..

Dozwolone dla:

Możemy również użyć wyrażenia regularnego (/^([\w. -]+)@([\w -]+) ((.(\w) {2,3})+)$ / i) aby zweryfikować format adresu e-mail jest poprawny lub nie.

var emailRegex = new RegExp(/^([\w\.\-]+)@([\w\-]+)((\.(\w){2,3})+)$/i);
 var valid = emailRegex.test(emailAddress);
  if (!valid) {
    alert("Invalid e-mail address");
    return false;
  } else
    return true;

Spróbuj tego

function isValidEmailAddress(emailAddress) {
    var pattern = new RegExp(/^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/);
    return pattern.test(emailAddress);
};

Możesz użyć tej funkcji

 var validateEmail = function (email) {

        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;


        if (pattern.test(email)) {
            return true;
        }
        else {
            return false;
        }
    };
