random: Jquery button getting a random image from array

jeudi 18 août 2016

Playing with jquery and I need help with this part on codepen.

I commented the part I need help with and could someone explain how to get a random image to display on img after I click the button

My code:

$('#switch').on('click',function(){
  //Help with this part 
  $('h1').html("I'm supposed to switch the picture but I can't do that");

I need #switch(button) to change the #duck(image) src to random src from the array I provided.
