Je ne sais pas trop comment faire ça. J'ai besoin de valider les adresses email en utilisant regex avec quelque chose comme ceci:
[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)
Ensuite, je dois exécuter ceci dans une fonction jQuery comme ceci:
$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");
$j('#email_ac').html(msg);
}
}
});
});
Où va la validation et quelle est l'expression?
function isValidEmailAddress(emailAddress) {
var pattern = /^([a-z\d!#$%&'*+\-\/=?^_`{|}~\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 */ }
Ceci est ma solution:
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);
};
Trouvé que RegExp ici: http://mdskinner.com/code/email-regex-and-validation-jquery
$(document).ready(function() {
$('#emailid').focusout(function(){
$('#emailid').filter(function(){
var emil=$('#emailid').val();
var emailReg = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/;
if( !emailReg.test( emil ) ) {
alert('Please enter valid email');
} else {
alert('Thank you for your valid email');
}
})
});
});
Lolz c'est beaucoup mieux
function isValidEmailAddress(emailAddress) {
var pattern = new RegExp(/^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/);
return pattern.test(emailAddress);
};
Je vous recommande d'utiliser le plugin jQuery pour Verimail.js .
Pourquoi?
Comment?
Incluez verimail.jquery.js sur votre site et utilisez la fonction:
$("input#email-address").verimail({
messageElement: "p#status-message"
});
Si vous avez un formulaire et que vous voulez valider l'email lors de l'envoi, vous pouvez utiliser la fonction getVerimailStatus:
if($("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);
La regex n'est pas autorisée pour:
[email protected]
[email protected]..
Permit pour:
[email protected]
[email protected]

Essaye ça
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);
};
Méthode native:
$("#myform").validate({
// options...
});
$.validator.methods.email = function( value, element ) {
return this.optional( element ) || /[a-z0-9._%+-]+@[a-z0-9.-]+\.[a-z]{2,4}/.test( value );
}
Source: https://jqueryvalidation.org/jQuery.validator.methods/
vous pouvez utiliser cette fonction
var validateEmail = function (email) {
var pattern = /^([a-z\d!#$%&'*+\-\/=?^_`{|}~\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;
}
};
Nous pouvons également utiliser une expression rationnelle (/^([\w.-]+)@([\w-]+)((.w=((w)&en2,3Buch-))) pour valider l'adresse e-mail. le format est correct ou non.
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;
