javascript 用于阻止注册表中垃圾邮件链接的代码

Question

我们在我们的网站上有一个会员注册表格，所有字段都通过 javascript 验证 _ 最后两次注册使用地址字段和备注字段发送了恶意软件 links _
验证码不是防止这种情况的好选择 _ 所以我查看了 javascript 中的正则表达式以禁止这些表单字段中的 'http://' 但我对如何将代码实现到原始表单验证中感到困惑_ 我想知道是否有人有一段 javascript 代码会在我们的表单中写入 'http://' _ 或者有一个 link 到我可以找到我们需要的 javascript 的地方_ 谢谢

Answer 1

我认为 honeypot technique 是一个非常优雅、简单的反垃圾邮件设备 - 只需用 css 隐藏一个字段，如果它被填充，你就知道这是一个垃圾邮件机器人在做，所以垃圾邮件投稿

Answer 2

正则表达式应如下所示：

var inputText = "my adreess is city ... and spam http://somelink... and another www.link... 50";

var regexClearSites = /(?:http|www)\S+\s*/g;

document.write( 
  
  inputText.replace(regexClearSites, '')

);

解释正则表达式：

(?:http|www)       # any text starting with "http" or "www"
\S+\s*             # till the next space
