检查字符串是否包含电子邮件地址？ [英] Check if a string contains an email address?

问题描述

如何检查以验证给定字符串是否包含电子邮件地址。

How can I check to verify that a given string contains an email address.

电子邮件地址也会包含在很多其他文本中。

The email address would be included with a lot of other text, as well.

此外，不一定要严格验证电子邮件地址本身。更多，只是想确保 [e-mail] 存在。

Also, not looking to necessarily strictly validate the email address itself. More so just wanting to make sure that [e-mail] is present.

示例字符串：

Overall I liked the service, but had trouble using the widget generator.

Want more info? You can contact me at [e-mail].

简单的javascript很好，但我确实碰巧使用jQuery，所以如果有某种帮助让这更容易的功能...去吧。

Plain javascript is fine, but I do happen to be using jQuery, so if there's some sort of helper function that makes this easier...go for it.
