[thelist] VBScript output randomizer

[Ken Schaefer]

The variable "touse" holds a value from 1 -> 4

You want a random element from an array numbered from 0 -> 3.

So, we will subtract 1 from the value of touse, and get that element from the array.

Try this in a web page:

<%
' Put Bill's code here to generate the random value stored in touse

Response.Write("Current value of touse is: " & touse & "<br />" & vbCrLf)
newTouse=touse-1
Response.Write("Subtracting 1 from touse. New value is: " & newTouse &  "<br />" & vbCrLf)
Response.Write("Getting this element from array. Value is: " & dancer(newTouse) &  "<br />" & vbCrLf)
%>

Hi Bill, and thanks for the reply.  One thing I do not understand from this, is how it ties in to the array I've already created:

<%
Dim dancer(3)

dancer(0)="#dancer1"
dancer(1)="#dancer2"
dancer(2)="#dancer3"
dancer(3)="#dancer4"
%>

Or, if I've not done the array correctly, how the code below will be written to tie it into the images that need to randomize.  Help please?

Thanks!!

Jenni

Hi Jenni,


I would do something like this:

<%
Function RandomNumber(intHighestNumber)
	Randomize
	RandomNumber = Int(intHighestNumber * Rnd) + 1 End Function


'if you have 4 images, you would call it like this:

touse = RandomNumber(4)

%>

Then, touse will hold a value of 1,2,3, or 4.

using your css rules pre-defined, you can simply output like this:

<div class="dancer" id="dancer<%= touse %>"></div>
