You cannot use a (.) to separate email addresses because at least one (.) usually appears in an email address and more than one can as well.

Email validation is best left to the server side, which would depend upon which server side language and mail routines you are using. Any javascript email validation would be just a 'front end' for that, and could be disabled by the user.

If you have a function to validate email addresses, it can be used with a comma delimited string by splitting the string into an array and applying it to each item in the array.

Use this java script

and it is workink fine

<script language="JavaScript1.2">
var testresults

function checkemail()
//var str=document.validation.txtAnchorEmail.value
var str=document.getElementById('ctl00_ContentPlaceHolder1_txtAnchorEmail').value;
var filter=/^.+@.+\..{2,3}$/

if (filter.test(str))
alert("Please input a valid email address!")
return (testresults)

function checkbae(){
if (document.layers||document.all)
