Hey JavaScript Guru's!
 

Ok i have this script that takes 2 items out of an array, then checks to make sure they arent identical.

Id like to boost this to 20 numbers, but i dont know how to structure the CHECK part.

Here is the check im using for the existing 2 item script ...

var s1=Math.floor(Math.random()*myimages.length)
if (s1==0)
s1=1
var s2=Math.floor(Math.random()*myimages.length)
if (s2==0)
s2=1

if(s1==s2){ if(s1==myimages.length) {s1=1;} else s1++; }



Now i need 20 items from my array without duplicating any of them, lol

Any ideas?

Keep an array of items you already selected. Then select untill you get an item from the original list that wasn't selected yet. Add that to the array of items you already selected. Be careful though: if you have less items in your original list than you want to select you could end up in an endless loop
