hi ...
what should the validation do? ... post the code you have so far ...
kind regards -
This is the script i am using for validation of single email id
[HTML]<script language = "Javascript ">
/**
* DHTML email validation script. Courtesy of SmartWebby.com (http://www.smartwebby. com/dhtml/)
*/
function echeck(str) {
var at="@"
var dot="."
var lat=str.indexOf (at)
var lstr=str.length
var ldot=str.indexO f(dot)
if (str.indexOf(at )==-1){
alert("Invalid E-mail ID")
return false
}
if (str.indexOf(at )==-1 || str.indexOf(at) ==0 || str.indexOf(at) ==lstr){
alert("Invalid E-mail ID")
return false
}
if (str.indexOf(do t)==-1 || str.indexOf(dot )==0 || str.indexOf(dot )==lstr){
alert("Invalid E-mail ID")
return false
}
if (str.indexOf(at ,(lat+1))!=-1){
alert("Invalid E-mail ID")
return false
}
if (str.substring( lat-1,lat)==dot || str.substring(l at+1,lat+2)==do t){
alert("Invalid E-mail ID")
return false
}
if (str.indexOf(do t,(lat+2))==-1){
alert("Invalid E-mail ID")
return false
}
if (str.indexOf(" ")!=-1){
alert("Invalid E-mail ID")
return false
}
return true
}
function ValidateForm(){
var emailID=documen t.frmSample.txt Email
if ((emailID.value ==null)||(email ID.value=="")){
alert("Please Enter your Email ID")
emailID.focus()
return false
}
if (echeck(emailID .value)==false) {
emailID.value=" "
emailID.focus()
return false
}
return true
}
</script>[/HTML]Comment

you just need to split() the string with the comma-seperated list of email-addresses and use your function for every resulting array element ...:
[CODE=javascript]var s = 'foo,bar';
var a = s.split(',');
// -> a stores now: ['foo', 'bar'][/CODE]

i am still learning javascripts...c an u plzz show a small example of wht u explainedComment

hi Pradeep, I give u a example. this will be useful for you.
[HTML]<html>
<head>
<script language="javas cript">
function splitThis()
{
var names = new Array();
var input = document.getEle mentById('myTex t').value;
names=input.spl it(";");
for(i=0;i<names .length;i++)
alert("Names["+i+"] is "+names[i]);
}
</script>
</head>
Enter the name with ";" inbetween them: &nb sp;<input type="text" id="myText">
<br/>
<input type="button" value="Split Names" onclick="splitT his()">
</html>[/HTML]
In the place of alert you use the code to validate the emails

:) the exampe is right above in my previous post ... just call a function with the comma-seperated string as its input ... after the split just loop over the resuting array and call you validation for every emai-address:
[CODE=javascript]
function check_all(c_s_l ist) {
var arr = c_s_list.split( ',');
for (var i = 0, l = arr.length; i < l; i++) {
var adr = arr[i];
// your validation here - may be you need some
// adaptions to handle the errors for every address
echeck(adr);
}
}
[/CODE]

ok thanks its working great now....hey i hve another problem....i need to validate like
pradeep jain:pradeep@ba c.com,pradeep new:new@abc.com
is there a way to do it....Comment
-
could you please explain in more detail: what is to validate?Comment

Hi Dude, whether pradeep jain & pradeep new are the first name and last name of the person who is having that mail id. You want to validate only the mail id not the name. If thats the case: have two arraysOriginally posted by pradeepjain
ex: code
[HTML] var myArray1 = new Array();
var myArray2 = new Array();
var input = document.getEle mentById('textV al').value; //This has the pradeep jain:pradeep@ba c.com,pradeep new:new@abc.com
myArray1 = input.split("," );
for(i=0;i<myArr ay1.length;i++)
{
myArray2 = myArray1[i].split(":")
// myArray2[0] ----> contains the Name
// myArray2[1] -----> contains the Id to be validates;
validate(myArra y2[1]);
}[/HTML]
This is the way u can do it. If u have doubts post back it. I will try to help u out.

-
the user might enter as
name:name@abc.c om,nam1:name1@a bc.com or
name@abc.com,na me1@abc.com or
name:name@abc.c om,name1@abc.co m or
name@abc.com
this is the problemComment

See you have to maintain standards inprder top insist the user that this is my scope and this is my limitation or you have to use two logic and check before validating if the user has given the name then logic1 if the user name not given then logic2 you have to go by that. I would choose the first one rather than writing n no. of logics and complicating your code. Any further clarification post ur doubtsOriginally posted by pradeepjain

basicly an email-validation needs to check 3 things:
1. check for the @-character in every possible address
2. some domain-name check
3. some check for a valid name
there for you just need 3 steps:
1. split the user-input at the seperator(s) he might use -> result is an array with potential email-addresses
2. for every element split at the @ ... if you get 2 elements check 1. is ok ... now goto 3
3. check the first and second elements now - the first is the name-check and the second the domain check ...
alternativly you could use a regex to check everything in step 2 together ...
