Hi! I am not sure if this is the right section to post this, but I am sure my issue would require some scripting..

Alright.. this is what I want to do.

Create a small app that generates a random 8 character code starting with a specific number or text. The code must consist of these first 3 characters "14k" and then 2 random letters, followed by 3 random numbers.

So it would look something like this: "14kth837"

Also, I want the app to save the codes that were already generated on a text doc so that they are not re-used.

Is there a method to do this?

Thanks

Yes, there are probably several ways of doing this:

The numbers can be generated using:

Code:

var Nx = String.random(10) //returns any number up to, but not including 10

The function above could also be used to generate an ASCII value and converted to it's corresponding character.
http://www.asciitable.com/

Code:

var Lx = String.fromCharCode(65); //65 would return the letter A

The whole lot can then be concatenated:

Code:

myCode = "14kth" + L1 + L2 + N1 + N2 + N3

Once you got that bit working, you'd then need to look at reading and writing to a text file. Depending on the number of these 'codes' generated though - that might be convoluted.

Can you explain this in more detail please? I am not too familiar with the string.charcode...

Thanks

Just put all the code in a script object and preview the page:

Code:

myLetter = generateRandomLetter() 

Debug.trace("You generated the letter "+myLetter+'\n\n');

//Generate a string of random letters

myString = "";

for (var i = 0; i < 10;i++){

   myString = myString + generateRandomLetter()
   }

Debug.trace("You generated the string - "+ myString+'\n\n')

function generateRandomLetter(){

n =  String.random(26); //  pick a number from 0 - 25

n = n + 65; //converts random into an ascii number for uppercase. 

/*
---------------------WHY?------------------------------------

if n = 0 then n + 65 = 65 which is the ascii code for 'A'
if n = 25 then n + 65 = 90 which is the ascii code for 'Z' 

ASCII codes here:

*/

l = String.fromCharCode(n) //the function changes the value in n to a letter by matching it to the corresponding ASCII code.
return l;
}
