Get random word from prompt imput

[Miguel]

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

}

You random number calculation is wrong.

// This will never give you 2. Only 0, 1
Math.floor(Math.random()*2);

// This will give you 0-2 outcomes
Math.round(Math.random()*2);
Math.floor(Math.random()*3);
