Add the below to the test procedure in order to validate basic email format
multi-value separated by comma. Does not handle phrases RFC-822 :)~ Enjoy


case "multiemail":
var emailStr = f.value.trim();
if(emailStr == ''){return true}; //the field is allowed to be empty


var mySplitResult = emailStr.split(",");
var reg1 = /(@.*@)|(\.\.)|(@\.)|(\.@)|(^\.)/; // not valid
var reg2 = /^.+\@(\[?)[a-zA-Z0-9\-\.]+\.([a-zA-Z]{2,3}|[0-9]{1,3})(\]?)$/; //
valid
for(i = 0; i < mySplitResult.length; i++){
var testVal = mySplitResult[i].trim() +'';if ( !reg1.test( testVal ) &&
reg2.test( testVal ) ) { // this address passes
}
else {return false;}
}
return true;
break;
