使电子邮件地址免受网页上的机器人攻击? [英] Making email addresses safe from bots on a webpage?

问题描述

在网页上放置电子邮件地址时，您是否将它们作为文本放置如下:

When placing email addresses on a webpage do you place them as text like this:

[e-mail]

或者使用一个聪明的技巧来试图欺骗电子邮件地址收集机器人?例如:

or use a clever trick to try and fool the email address harvester bots? For example:

HTML 转义字符:

joe.somebody@company.com

Javascript 解密器:

function XOR_Crypt(EmailAddress)
{
    Result = new String();
    for (var i = 0; i < EmailAddress.length; i++)
    {
        Result += String.fromCharCode(EmailAddress.charCodeAt(i) ^ 128);
    }
    document.write(Result);
}

XOR_Crypt("êïå®óïíåâïäùÀãïíðáîù®ãïí");

人工解码:

[e-mail]

joe.somebody AT company.com

你用什么或者你什至打扰?

What do you use or do you even bother?

推荐答案

在 CSS 中处理内容和属性:

Working with content and attr in CSS:

.cryptedmail:after {
  content: attr(data-name) "@" attr(data-domain) "." attr(data-tld); 
}

<a href="#" class="cryptedmail"
   data-name="info"
   data-domain="example"
   data-tld="org"
   onclick="window.location.href = 'mailto:' + this.dataset.name + '@' + this.dataset.domain + '.' + this.dataset.tld; return false;"></a>

禁用javascript时，只是点击事件不起作用，仍然显示电子邮件.

When javascript is disabled, just the click event will not work, email is still displayed.

另一种有趣的方法(至少没有点击事件)是利用从右到左的标记来覆盖书写方向.更多相关信息:https://en.wikipedia.org/wiki/Right-to-left_mark

Another interesting approach (at least without a click event) would be to make use of the right-to-left mark to override the writing direction. more about this: https://en.wikipedia.org/wiki/Right-to-left_mark
