How to validate two email Id separated by ; using jquery/ javascript

Question

<div class="fluid field">
    <label>e-mail Ids:</label>
    <textarea rows="1" style="height:100px" id="mailids" value="<%- mailids %>"></textarea>
 </div>

below is my JS code which i tried

'change #mailids': function (e) {
        var strVale = $(e.target).val();
        if (strVale.substring(strVale.length - 1) == ";") {
            strvalue = strVale.substring(0, strVale.length - 1);
        }
        var arr = strVale.split(';');
        var isValid = true;
        var self = this;

        arr.forEach(function (item) {
            var x = item;
            var atpos = x.indexOf("@");
            var dotpos = x.lastIndexOf(".");
            if (atpos < 1 || dotpos < atpos + 2 || dotpos + 2 >= x.length) {
                isValid = false;
            }
        });
      }

I need to validated the two email id separated by ;(semi colon) if its not valid email it should show error message

below input also accepts as valid

What is the issue with your current code? How exactly does it fail? — , May 10 '19 at 08:40
using regex i can validated only one email after validating i need to separate it by ; — chethu, May 10 '19 at 08:40
@ChrisG the issue is even if i give `colon (-)` also it will accept as valid email id other than `;` it should not accept anything — chethu, May 10 '19 at 08:41
Why do you have value="" on the textarea? It should be `<%- mailids %>` — mplungjan, May 10 '19 at 08:43
So if I understand you correctly, your issue *isn't* `How to validate two email Id separated by ; using jquery/ javascript`, but your issue is `How to validate email`? — , May 10 '19 at 08:44
@ChrisG No not to validate email if user gives multiple email it should be separated by ; — chethu, May 10 '19 at 08:46
If you use a suitable regex for the address check, that input will fail because it is treated as a single address and thus won't pass the regex check. — , May 10 '19 at 08:55
Your issue is almost impossible. Instead have one email per field. If they need more, then have them add a field. — mplungjan, May 10 '19 at 11:13

Split the email is based on the semicolon. And for each email id, use a regular expression to validate email.

function validateEmail(email) {
    var re = /^(([^<>()\[\]\\.,;:\s@"]+(\.[^<>()\[\]\\.,;:\s@"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
    return re.test(String(email).toLowerCase());
}

For regular expression based validation. See this answer.

@ScrapCode from this answer i can't pass two email id – chethu May 10 '19 at 08:45
@chethu, for each email id (that you got after splitting), use the above function to validate. – ScrapCode May 10 '19 at 08:46

Just split email id's by comma or semicolon after that validate them

this will help you

 var x = getEmails();
var emails = x.split(",");
emails.forEach(function (email) {
  validate(email.trim());
});
