1.
function makeid(length) {
var result = '';
var characters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789';
var charactersLength = characters.length;
for ( var i = 0; i < length; i++ ) {
result += characters.charAt(Math.floor(Math.random() *
charactersLength));
}
return result;
}
2.
let r = (Math.random() + 1).toString(36).substring(7);
console.log("random", r);
3.
function randomString(len) {
var str = ""; // String result
for (var i = 0; i < len; i++) { // Loop `len` times
var rand = Math.floor(Math.random() * 62); // random: 0..61
var charCode = rand += rand > 9 ? (rand < 36 ? 55 : 61) : 48; // Get correct charCode
str += String.fromCharCode(charCode); // add Character to str
}
return str; // After all loops are done, return the concatenated string
}
console.log(randomString(10));Copyright © 2021 Codeinu
