(JavaScript) Generating Random ASCII Strings

Demonstrates how to generate random us-ascii strings.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

success = false;

var fortuna = new CkPrng();

var bDigits;
var bLowercase;
var bUppercase;

// Generate random strings having only lowercase chars (a-z)
// Disallow digits and uppercase and only allow lowercase
bDigits = false;
bUppercase = false;
bLowercase = true;

var i;

console.log("-- only lowercase alpha (a-z)");
for (i = 1; i <= 10; i++) {
    // Generate 20-character strings.
    console.log(fortuna.RandomString(20,bDigits,bLowercase,bUppercase));
}

// Allow both lowercase and uppercase alpha chars
bUppercase = true;
console.log("-- lower and uppercase alpha (a-zA-Z)");
for (i = 1; i <= 10; i++) {
    // Generate 20-character strings.
    console.log(fortuna.RandomString(20,bDigits,bLowercase,bUppercase));
}

// Allow digits (0-9)
bDigits = true;
console.log("-- digits and lower/uppercase alpha (0-9a-zA-Z)");
for (i = 1; i <= 10; i++) {
    // Generate 20-character strings.
    console.log(fortuna.RandomString(20,bDigits,bLowercase,bUppercase));
}

// Allow only digits (0-9)
bUppercase = false;
bLowercase = false;
console.log("-- only digits (0-9)");
for (i = 1; i <= 10; i++) {
    // Generate 20-character strings.
    console.log(fortuna.RandomString(20,bDigits,bLowercase,bUppercase));
