NEED YOUR HELP !

Question

hey you i new at javascript and i need your HELP !! i want to do like that

---> var Random = Math.floor(Math.random() * passW1.length * 7)
---> I WANT TO MATH.RANDOM CHOOSE 7 VALUES OF passW1 but when i put like on up code doesnt work !

---------------THE CODE---------------------------------------------------------------------------------

var passW1 = ["A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "K", "R", "S", "T", "U", "V", "W", "X", "Y", "Z", "a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "k", "r", "s", "t", "u", "v", "w", "x", "y", "z", "0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "*", "&", "%", "_", "-", ".", ",", ":", "~"];

var Random1 = Math.floor(Math.random() * passW1.length);

function go() {

var final = alert('Your PassWord is ' + passW1[Random1]);

}

Answer 1

Yeah but it reduces engagitivity.
Even I stopped reading your solution from halfway as it captures less attention. This is also why many answers by me are quite short.

Answer 2

You could use a for loop

Answer 3

You array (refering to the password generator code in you playground) seems to have repeated letters (k and K) and missing some characters (q and Q as letters, and other signs..). To list them, you can run this code:

var passW1 = ["A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "K", "R", "S", "T", "U", "V", "W", "X", "Y", "Z", "a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "k", "r", "s", "t", "u", "v", "w", "x", "y", "z", "0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "*", "&", "%", "_", "-", ".", ",", ":", "~"];

var i=passW1.length;
var k=[];
while (i--) { k.push(passW1[i].charCodeAt(0)); }
k.sort(function(a,b) { return a-b; });
i=k.length;
var j=-1;
while(i--) {
if (j!=-1) {
if (k[i]==j) document.write('repeat: '+k[i]+' '+String.fromCharCode(k[i])+'<br>');
else if (k[i]!=j-1) {
document.write('hole between: '+k[i]+' '+String.fromCharCode(k[i])+' and '+j+' '+String.fromCharCode(j)+' :');
for (var n=k[i]+1; n<j; n++) document.write(' '+String.fromCharCode(n));
document.write('<br>');
}
}
j = k[i];
}

So, I will suggest few things:
+ use a String (array like) instead an array of string to store individual characters
+ rather store forbiden chars instead of allowed (less longer)

Well, implementing these few things, and forbiden chars based on those not used in your code, will give:

var rc, p ='', n = 7, forbidenchars = '{|}q`[\\]^Q;<=>?@/+\'()';
while (n--) {
do rc = String.fromCharCode(Math.floor(89*Math.random())+38);
while (forbidenchars.indexOf(rc)!=-1)
p += rc;
}
document.write('<br>'+p+'<br><br>');

Answer 4

Long answers aren't a problem if they are relevant, isn't it? ;P

Answer 5

so i need to do that:

var Random1 = Math.floor(Math.random() * passW1.length);
var Random1 = Math.floor(Math.random() * passW1.length);
var Random1 = Math.floor(Math.random() * passW1.length);
var Random1 = Math.floor(Math.random() * passW1.length);
var Random1 = Math.floor(Math.random() * passW1.length);
var Random1 = Math.floor(Math.random() * passW1.length);
var Random1 = Math.floor(Math.random() * passW1.length);

?????? fuk

Answer 6

you need to select 7 random character, otherwise it will output only one

Answer 7

That's one way, yep.

var a = Math.floor( Math.random() * passW1.length );
var b = Math.floor( Math.random() * passW1.length );
alert( passW1[a] + passW1[b] );

Answer 8

ok i will try ! ty for help :3

Answer 9

Make a string and add to it with a loop. Easy!

var pass = "";
for (var x = 0; x <= 7; x++){
pass += (Math.floor(Math.random() * passW1.length));
}
alert("Your password is: " + pass);

Just giving correct code/answer will not teach anything...

Answer 11

when I was rewriting the code I found it very easy to do:

Answer 12

algo

list of letters
str
for loop
str+= random sel from list of letters

alert str
