Obfuscating E-mail Addresses

拒绝电子邮件地址

Do you ever wonder how your E-mail address gets on so many spam mailing lists? One way spammers collect E-mail addresses is from web pages. To help combat this problem, you can make your E-mail address show up in scrambled javascript in the HTML source, yet it it will look and work correctly in the browser. This is done with the mailto plugin.

Send inquiries to
{mailto address=$EmailAddress encode="javascript" subject="Hello"}

Technical Note: This method isn't 100% foolproof. A spammer could conceivably program his e-mail collector to decode these values, but not likely.

技术提示:这种方法不是100%安全的。一个猎头可能知道编写他的电子邮件收集器来解码,但不是很可能的。
