• Mass of text, cherry pick email addresses 7 answers

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

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

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

Example string:

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

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.

Answer 1

You can use this:

var StrObj = "whatever, this is my email [e-mail] other text";
var emailsArray = StrObj.match(/([a-zA-Z0-9._-]+@[a-zA-Z0-9._-]+\.[a-zA-Z0-9._-]+)/gi);
if (emailsArray != null && emailsArray.length) {
    //has email
}

This also lets you get the email address from the array, if you need it.

Answer 2

Try

/\b[a-z0-9-_.]+@[a-z0-9-_.]+(\.[a-z0-9]+)+/i.test(text)
