Question

i have data having emails:
data pattern is like: first_name last_name email


data = foo bar [e-mail], foo baz [e-mail],foo foo [e-mail],[e-mail] , bar baz [e-mail]

It may contain spaces. I have to valiadte all the emails by extracting the data.
Note: There may be spaces between words so that spliting by space gives me more some unwanted data …

function validate() {
    email_data = data.split(',') // This will get the all data spliting by ','
    for (i = 0; i<email_data.length; i++) {
        email_new_data = email_data.split(' ')  //spliting data by space

        // Now I could not find the way to extract emails (only ) from data
    }
}

Any suggestion will be helpful.. thanks

The following function split the main data string into an array; which then can be parsed with RegExp. As far as I can tell you only want to get the email address; so, we use a Regular Expression to match an email address. If it matches, you have a valid email. If there’s no match; then basically there’s no valid email on the given segment.

Please note that Regular Expression 100% success Email Validation is just impossible; because the RFC is just extremely complicated, check more about here: http://www.ex-parrot.com/pdw/Mail-RFC822-Address.html

function validate() {
    data = "foo bar [e-mail], foo baz [e-mail],foo foo [e-mail],[e-mail] , bar baz [e-mail]";
    email_data = data.split(','); // This will get the all data spliting by ','
    for (i = 0; i < email_data.length; i++) {
        // Get emails, change console.log to alert if you don't know how to use console.
        console.log(email_data[i].match(/[\w._+-]+@[\w._+-]+\.[\w]{2,6}/));
    }
}
validate();
