instead of incrementing i, you could create a function that generates a random number between 1 and 5, and have a while loop determine whether or not it is the same as the last number.
for example:
function getRand(max, min){
var rand;
rand = Math.floor(Math.random() * (max – min + 1) + min);
return rand;
}
And then wherever you increment i, make a variable called something like oldI and set it to i.
var oldI = i;
and then put in a while loop to repeat the random function until you get a new number.
while ( i === oldI ){
i = getRand(5, 1);
}
I didn’t do a great job (not exactly sure how your code works, haven’t written jquery in a while), but here’s a forked example: http://codepen.io/WillsonSmith/pen/ELGfC
Also I think my max/min values are wrong, you may want to do
`getRand(4, 0);`
and change the randomiser to
`rand = Math.floor(Math.random() * (max – min));`
