下面是代码，我指的是代码片段：Mailchimp的“Captcha”验证如何工作？
<!-- real people should not fill this in and expect good things - do not remove this or risk form bot signups-->
<div style="position: absolute; left: -5000px;">
<input type="text" name="[IDENTIFYING CODE HERE]" value="">
</div>
然后形式发送过自己的网站，在这里的JavaScript（jQuery的）验证发生。
<script type="text/javascript" src="http://downloads.mailchimp.com/js/jquery.mailcheck.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
try {
var domains =['hp.com','hotmail.co.uk','yahoo.co.uk','yahoo.com.tw','yahoo.com.au','yahoo.com.mx','gmail.com','hotmail.com','yahoo.com','aol.com','comcast.net','msn.com','seznam.cz','sbcglobal.net','live.com','bellsouth.net','hotmail.fr','verizon.net','mail.ru','btinternet.com','cox.net','yahoo.com.br','bigpond.com','att.net','yahoo.fr','mac.com','ymail.com','googlemail.com','earthlink.net','xtra.co.nz','me.com','yahoo.gr','walla.com','yahoo.es','charter.net','shaw.ca','live.nl','yahoo.ca','orange.fr','optonline.net','gmx.de','wanadoo.fr','optusnet.com.au','rogers.com','web.de','ntlworld.com','juno.com','yahoo.com.sg','rocketmail.com','yandex.ru','yahoo.co.in','centrum.cz','live.co.uk','sympatico.ca','libero.it','walla.co.il','bigpond.net.au','yahoo.com.hk','ig.com.br','live.com.au','free.fr','sky.com','uol.com.br','abv.bg','live.fr','terra.com.br','hotmail.it','tiscali.co.uk','rediffmail.com','aim.com','blueyonder.co.uk','telus.net','bol.com.br','hotmail.es','email.cz','windowslive.com','talktalk.net','home.nl','t-online.de','yahoo.de','telenet.be','163.com','embarqmail.com','windstream.net','roadrunner.com','bluewin.ch','skynet.be','laposte.net','yahoo.it','qq.com','live.dk','planet.nl','hetnet.nl','gmx.net','mindspring.com','rambler.ru','iinet.net.au','eircom.net','yahoo.com.ar','wp.pl','mail.com','emmis.com','hotmail.de','lireo.com','gmx.at','ukr.net','zol.co.zw'];
var tdomains = [];
$('#MERGE0').on('blur', function() {
$(this).mailcheck({
domains: domains,
topLevelDomains: tdomains,
suggested: function(element, suggestion) {
var msg = 'Hmm, did you mean '+suggestion.full+'?';
if ($('#MERGE0_mailcheck').length > 0){
$('#MERGE0_mailcheck').html(msg);
} else {
element.after('<div id="MERGE0_mailcheck" class="errorText">'+msg+'</div>');
}
},
empty: function(element) {
if ($('#MERGE0_mailcheck').length > 0){
$('#MERGE0_mailcheck').remove();
}
return;
}
});
});
} catch(e){ console.log(e); }
});
</script>
在外行人的话来说，这怎样 “验证码” 工作？
是什么阻止bot识别并跳过该字段？
是什么阻止一个人意外地进入该领域并进入某些东西？
除非我失去了一些东西，这似乎是不会很有效，但它似乎工作？
