Math.floor(); method returns a decimal value to the lowest value,
so (Math.floor(6.34) = 6) & (Math.floor(6.78) = 6)
Math.random(); method returns a decimal value between 0 & 1
the decimal value can be 0.642512573 or 0.2346572 or 0.85673 (randomly generated)
Multiplying this number by 150 return a minimum of Math.floor(0.0000001 * 150 ) = 0 -> to Math.floor(0.999999 * 150) = 149
by increasing the number 150 you can use more characters in the ASCII table and can have more chances to have random characters, I used it only as an exemple
if you want to make sure different characters can be used, you can use a contain method to look if the character exists in the password
for (var i = 0; i < intLength; i++){
var random = Math.floor(Math.random() * 150);
if ((random >= 48 && random <= 57) || (random >= 65 && random <= 90) || (random >=97 && random <= 122)){
//Store character in value
var strChar = String.fromCharCode(random);
//Character is initially not contained in the string
var boChar = false;
for (var z = 0; z < strValue.length; z++){
if (strValue.substr(z, z + 1) == strChar){
//The character is contained in the string, value is now true
boChar = true;
}
}
if (!boChar){
//If character is not contained in the string, the character is added to the string, otherwise it is not added
strPassword += strChar;
}
} else{
i--;
}
}
