Hello,

Is is there a way to insert a button to a PDF that would generate a random number (up to 10 numerical characters) but never repeat the same numbers for every time the button is clicked? Any help is appreciated.

Thank you,

Ed

If you want the number not to repeat you will need to keep a record of all

previous numbers and compare the new number to it when generating it.

Add a hidden text field and put each number you generate into it.

When generating a new number, compare it to the contents of that file. If a match is found, generate a new number, until you get a unique one. Then add it to the field as well, and repeat.

You won't be able to generate a random number with no chance of repeats using any computer language. There are just pseudo-random number algorithms which will get you close. Look at the JavaScript Math object. The code below will generate a random number from 0 to 99.

Math.floor(Math.random() * 100);

What you really want is an alpha-numeric Universally Unique Identifier. You can find one of those here...
