Question

I’m trying to run a random function but haven’t quite figured it out:

<script>

function randomFrom(array) {return array[Math.floor(Math.random() * array.length)];}

function randomchords(){randomFrom(['poop()', 'poop2()', 'poop3()']);}               



function poop() { $(function() {ionian_c_vi() });  }                          

function poop2() {  $(function() {ionian_c_iii() }), $(function() {ionian_c_iv() });  }                      

function poop3() { $(function() {ionian_c_vi() }), $(function() {ionian_c_i() }), $(function() {ionian_c_ii() });  }  

</script>

and then:

<button onclick="randomchords()" >Get some random chords</button>

Am I on the right track?

Answer 1

One option is to use window object:

function randomchords() {
    var func = randomFrom(['poop', 'poop2', 'poop3']);
    window[func]();
}

Pay attention that you should remove parentheses from function names in the array.

Another option is to remove quotes from the variant above and call functions directly:

function randomchords() {
    var func = randomFrom([poop, poop2, poop3]);
    (func)();
}
