Genrate Random Key/Alpha-Numeric String using java Script

In this blog I am going to show you how to generate Random String/key of alpha-numeric values using java script, which may help us in many way like generate random key, any strong random password e.t.c 

Here is function which generate random string.

var string=' ';

 function randomString(){
    
var random_string=' ';  // Empty Random String
      
 var chars = "0123456789ABCDEFGHIJKL!@#$%^&* ()MNOPQRSTUVWXTZabcdefghiklmnopqrstuvwxyz";  // Characters from where random string generate

var string_length = 5;  //Length of random string

for (var i=0; i<string_length; i++) {
            var rnum = Math.floor(Math.random() * chars.length);
            random_string += chars.substring(rnum,rnum+1);  //generate random string
        }

string=random_string;  //here is your generated random string
alert(random_string);
}

enjoy with your random key. :)
