reset 'random' math

Question

I've got a random generator my using arrays and the following string to randomize:

var doelgroepRand = doelgroepArray[Math.floor(Math.random() * doelgroepArray.length)];

/

var divergeerIdee = 'Laat een' + ' ' + doelgroepRand + ' ' + watRand + ' ' + handelingRand

This goes into

$('#something').click( function() { 
event.preventDefault();
alert(divergeerIdee); });
});

But to get a new set of random items, you need to refresh the page. I want that, on click, everything is 'resetted' and you get new random items.

What is the string I need?

Answer 1

Simply pack it all in a javascript function. Eg:

function createRandom() {
  var doelgroepRand = doelgroepArray[Math.floor(Math.random() * doelgroepArray.length)];
  return divergeerIdee = 'Laat een' + ' ' + doelgroepRand + ' ' + watRand + ' ' + handelingRand
}


$('#something').click( function() { 
    event.preventDefault();
    alert(createRandom()); 
    alert(createRandom()); 
  });
});
