原标题:String Dot String (Mail without Domain) RegEx

确实,这块 simple子上了。 需要它验证一个插座,即没有“@domain.xxx”的邮件。

它必须完成以下规则:

  • there must be a string (only letters) starting.
  • there must be a string (only letters) ending.
  • this two strings must be separated by a dot.
  • the complete string mustn t contain any numbers or simbols.

我正在尝试采用如下办法:/^[a-z]+$/^>+$/[a-z]+$/i。 ......但没有成功。

最佳回答
/^[A-Za-z]+.[A-Za-z]+$/

该中心将编写文件ASCII。

如果你也想允许国际信(美国等)尝试

/^[^Wd_]+.[^Wd_]+$/

“非字母数字性,而不是数字性,而不是强调性”。

问题回答

/^[a-zA-Z]+.[a-zA-Z]+$/?
