Split an array in JS 1

[A1Pat]

How can I translate this ASP code to JS code

	<% 
						arrChannels = Split(Session("cam_no"), ",")
						For Each strOneWord in arrChannels
	response.write strOneWord & "<BR>"
 	
						Next
	%>

To simply explain the ASP code on the above, all it does is to take a string (ie: 1,2,3,4,5) and break it down then print it one by one in a single line such as:
1
2
3
4
5
and so on.

Thanks!

Hi

Then you do not split an array. You split a string to an array.

<script type="text/javascript">
arrChannels=[i]'whatever'[/i].split([i]','[/i]);
[b]for[/b] (i=0;i<arrChannels.length;i++) {
  document.write(arrChannels[i]+[i]'<br>'[/i]);
}
</script>

Of course, you can not access session objects on client-side.

Do something like this to get cam_no into a client side array, I have to all the time:

ASP

var channelsString = Session("cam_no")

Javascript

var channelsArray = "<%=channelsString%>".split(",");

<.

Since the cam_no is getting from a field in a form, I'm going to stick that string into the field and send it to the js code to do the split like Feherke suggested.

<script type="text/javascript">
cam_no = Channel.value;
arrChannels='cam_no'.split(',');
for (i=0;i<arrChannels.length;i++) {
  document.write(arrChannels[i]+'<br>');
}
</script>

Lets find out, shall we!

by the way, I hope u don't mind I'm doing a short cut here asking u guy a easy question that I can obtain from doing a little search elsewhere...

how can I do a if...else to validate whether the cam_no is a string with "," or not. I use to do this validation for email address

if (document.contactUs.email.value.indexOf("@") == -1 || document.contactUs.email.value.indexOf(".") == -1)

but I don't think I want to use the same thing for this particular case. In another word, I want to say "if the string cam_no has (,) then... do the split..."

thanks!

Hi guys,

why this Split doesn't have a result like the ASP one I had on the above, I test the output from this code

		var arrChannels=m_chNum.split(",");
		for (i=0;i<arrChannels.length;i++) {
		  document.write(arrChannels);
		}

and here is the result
1,21,2

Hi

You output the whole array there.

document.write(arrChannels[red][i][/red]);

Thanks Feherke for the info!

If Feherke of someone can help fix up this code a little 'cause I just find out this code has a small flaw

<script type="text/javascript">
cam_no = Channel.value;
arrChannels='cam_no'.split(',');
for (i=0;i<arrChannels.length;i++) {
  document.write(arrChannels[i]+'<br>');
}
</script>

and the flaw is... what if the Channel.value is not 1,2,3... but the value might be 1,12,15,etc. then the document.write(arrChannels) will then not neccessary reflect each of then Channel.value in the original string, won't it?

So, my goal is now find a way to display each of the value in the Channel string instead of the of the For loop.

 

[A1Pat]

Nevermind... Thank you for NOT reply this stupid question.

I either must be high or stupid to realize this line

document.write(arrChannels+'<br>');

... Sorry anyone if you had to view the question.

Don't be so hard on yourself A1Pat. If I got paid for each time I chased something like that I could have retired DateTime end = DateTime.Now.AddYears(-10);
