javaScript question

[Scott]

I have the following function below in my ASP that I am
having a problem with, because I'm not that familiar with
javaScript. What I want to know is how can I tell that I
am at the end of my For-Loop, so I can prevent an extra
comma from being appended to lstRescipients variable (line
7)?

1 function getRecipients(){
2 var lstRecipients = "";
3 var lst = document.getElementById
("lstEmails");
4 for(var i=0;i<lst.options.length;i++){
5 //if (lst.options[i].selected){
6 lstRecipients +=
lst.options[i].value;
7 lstRecipients += ",";
8 //alert(i);
9 //alert(lstRecipients);
10 //}
11 }
12 return lstRecipients;
13 }

This isn't the right group for javascript issues. .scripting.jscript is a
decent one for such questions.

hi,
why don't you make this:
if(i == lst.options.length)
{
actionX;
actionJJHJ;
or break the for loop, thus:
break;
}
I hope that helps you.

after the loop, trim off the last character.....

I have to sort of 50/50 disagree with you Ray.

This is an ASP group which can be both coded in VBscipt & javascript,
because most people code in VBscript thats what we see the most here.

But I do agree that the other group would get a better response
because more people in that group will know javascript more than the
people in this group.

I myself am currently learning Jscript/Javascript and will post
questions in the other group about problems in that language more.

This is not a knock at you as I've seen alot of your posts and your
very helpful (even to me in the past :))

oops, just noticed he's using client side code, so yes the other group
will be better as ASP is a serverside group.

I wish there were more <%@ language=jscript %> posts. I use vbscript, but I
like to look at jscript code more for some reason. :]

lol, well you can look at mine all the time if you wish, I just
converted over to Jscript ASP and learning more every day... I've now
started posting in

comp.lang.javascript
ms.public.scipting.jscript

I needed to learn how to do client side coding and since javascript is
the choice language for that I thought I'd best learn it so I can code
it from scratch rather than find other peoples and "play" with it. So
I'm now coding in Jscript server-side where possible.

I, for one, make every effort to respond with JScript and VBScript solutions
when I post in here. We're 100% JScript over here, FWIW.

Hi,

You would need to add one more if statement around line 7
that checks to see if your loop variable (i) is at the
last item you are checking.

Try:
if(i<lst.options.length){
lstRecipients += ",";
}

That should work fine.
