Select random function

Question

I have a list of functions:

    function randomiseiconscycle1() {
    $("#iconTwoContainer img, #iconFiveContainer img, #iconSevenContainer img").fadeIn(300);
    setTimeout( function(){
        $("#iconTwoContainer img, #iconFiveContainer img, #iconSevenContainer img").fadeOut(300);
    },200);

function randomiseiconscycle2() {
    $("#iconOneContainer img, #iconSixContainer img").fadeIn(300);
    setTimeout( function(){
        $("#iconOneContainer img, #iconSixContainer img").fadeOut(300);
    },200);
}

everytime i click this button i have i want to activate one of the 8 functions (like above) randomly.

any help would be much appreicated.

Answer 1

Put references to the functions in an array:

var iconcycle = [
  randomiseiconscycle1, randomiseiconscycle2,
  randomiseiconscycle3, randomiseiconscycle4,
  randomiseiconscycle5, randomiseiconscycle6,
  randomiseiconscycle7, randomiseiconscycle8
];

Now you can pick one at random and call it:

iconcycle[Math.floor(Math.random() * iconcycle.length)]();
