Get random word from prompt imput

  • # March 2, 2013 at 7:59 am

    I’m having a tough time doing this.

    And what I mean is, pull a prompt box, and if you input either “Test1″ Test2” “Test 3”, then there’s a random chance that when you click okay, an alert box says either test1, test2, test3 randomly.

    Any idea?

    You could switch the text to be outputted using a `switch` statement with a random number generation as the condition to switch:

    var numRand = Math.floor(Math.random()*2) // generate number between 1 and 3

    switch(numRand) {

    case 0:
    // code for 1st scenario
    case 1:
    // code for 2nd scenario
    case 2:
    // code for 3rd scenario
    // what to do if, for some reason, an invalid number was parsed

    You random number calculation is wrong.

    // This will never give you 2. Only 0, 1

    // This will give you 0-2 outcomes

    Don’t use Math.round(Math.random()*2), unless you want the chance to get 1 to be twice as much as the chance to get 0 or 2, as in 25% 50% 25% chance.
