Forms >>> Extract Email.

Visitors sometimes include their email address inside the message field when they fill out forms. To deal with this, this script parses through the string and uses a Regular Expression to find then return a comma-separated list of the valid email addresses it finds.

(For this demo, enter some text in the box and then click out of the field. If you included
one or more valid email addresses, they will be displayed in the Email field below the box.)

Email:

Add the below code to the <body> section of your page:

<script language="javascript" type="text/javascript">

<!-- Begin
function findEmailAddresses(StrObj) {
var separateEmailsBy = ", ";
var email = "<none>"; // if no match, use this
var emailsArray = StrObj.match(/([a-zA-Z0-9._-]+@[a-zA-Z0-9._-]+\.[a-zA-Z0-9._-]+)/gi);
if (emailsArray) {
email = "";
for (var i = 0; i < emailsArray.length; i++) {
if (i != 0) email += separateEmailsBy;
email += emailsArray[i];
      }
   }
return email;
}
//  End -->
