Forum :: Programming :: JavaScript Rock,paper, scizzors

been learning some javascript, but im having a hard time making the computers choice random between the outcomes of rock paper and scizzors.. :P I cant manage the the outcome to be random between the 3 chances :/ Maybe someone can help me? Thanks in advanced ^^

var rock = rock < paper;

var paper = paper < scizzors;

var scizzors = scizzors < rock;

var userChoice = prompt("Do you choose rock, paper, or scizzors?");

var rockPaperScizzors = function (outcome) {

  if (userChoice > rock) {

     return ("You lose");

  } else {

     return ("You win!");

  }

};

var rockPaperScizzors = function (outcome) {

  if (userChoice > paper) {

     return ("You lose");

  } else {

     return ("You win!");

  }

};

var rockPaperScizzors = function (outcome) {

  if (userChoice > scizzors) {

     return ("You lose");

  } else {

     return ("You win!");

  }

};

var computerChoice1 = Math.random();

var computerChoice2 = Math.random();

var computerChoice3 = Math.random();

var computerChoice = function (outcome) {

    if (computerChoice1 === rock) {

    console.log(computerChoice1 = 0,0.33);

} else if (computerChoice2 === paper) {

    console.log(computerChoice2 = 0,0.66);

} else if (computerChoice3 === Scizzors)

    console.log(computerChoice3 = 0.67,1);

};

I know it's probably a bit late, but here goes: 

/*ROCK PAPER SCISSORS*/

/*

1 = Rock

2 = Paper

3 = Scissors 

*/

var randomInt = Math.floor(Math.random() * 3) + 1; //randomint between 1 and 3

var computerChoice = "";

if (randomInt == 1) computerChoice = "rock";

else if (randomInt == 2) computerChoice = "paper"

else if (randomInt == 3) computerChoice = "scissors";

var userChoice = ""; 

while(userChoice.toLowerCase() != "rock" &&

userChoice.toLowerCase() != "paper" &&

userChoice.toLowerCase() != "scissors"){

userChoice = prompt("Please enter Rock Paper or Scissors");

} //while the input isn't either rock paper or scissors, keep asking the visitor to enter something valid

var status ="";

switch(computerChoice){ 

case "rock":

if (userChoice=="rock") status="drew";

else if (userChoice=="paper") status="win";

else if (userChoice=="scissors") status="lose";

break;

case "paper":

if (userChoice=="rock") status="lose";

else if (userChoice=="paper") status="drew";

else if (userChoice=="scissors") status="win";

break;

case "scissors":

if (userChoice=="rock") status = "win";

else if (userChoice=="paper") status="lose";

else if (userChoice=="scissors") status="drew";

break;

} //comparison between the two. Could probably be done in less code using integers but oh well. 

alert("You: " + userChoice.toLowerCase() + ". \nComputer: " + computerChoice.toLowerCase() + ".\nResult: You " + status);

this is a way I got it working :) hope this helps! https://tehsausage.com/paste/rockpaperscissors
