使用jQuery和regex驗證電子郵件地址我不太確定該怎么做。我需要使用regex驗證電子郵件地址，如下所示：[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+(?:[A-Z]{2}|com|org|net|edu|gov|mi
l|biz|info|mobi|name|aero|asia|jobs|museum)然后，我需要在這樣的jQuery函數中運行這個函數：$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);
}
}
});});驗證到哪里去了，表達式是什么？

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);};

$(document).ready(function() {$('#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');
}
})
});});- 3 回答
