我不太清楚如何做到这一点.我需要使用正则表达式验证电子邮件地址,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|mil|biz|info|mobi|name|aero|asia|jobs|museum)

然后我需要在这样的jQuery函数中运行它:

$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);
            }
        }
     });
});

验证在哪里以及表达式是什么？

我一直在开发一个脚本,现在我很难过.我尝试过很多来自Google的Regex并且没有用过,这是我的代码:

$(document).ready(function() {
    var email_check = /^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,6}$/;
    num = 0;
    $('#email').focus(function() {
        $('#email_check').show();
        $(this).keyup(function() {
            error = 0;
            var email = $('#email').val();
            num = num+1;
            if(!email_check.test(email)) {
                error = 1;
            }
            if(error == 0) {
                $('#email_check').html('O'+num+email+error);
            }else if(error == 1) {
                $('#email_check').html('X'+num+email+error);
            }
        });
    });
});

任何帮助都很棒,谢谢!
