Validate Multiple Emails Comma Separated with javascript

Question

I want to validate a string which can be an email or multiple emails separated by commas.

For example:

bill.gates@hotmail.com -> TRUE
bill -> FALSE

Answer 1

try this

     function validateEmails(string) {
        var regex = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/;
        var result = string.replace(/\s/g, "").split(/,|;/);        
        for(var i = 0;i < result.length;i++) {
            if(!regex.test(result[i])) {
                return false;
            }
        }       
        return true;
    }

accepts both comma and semicolon as separator, change that if you want only comma as separator
