I realise there is a lot of topics on this subject but I believe this one is different:
The goal is to get an value from an array on a random location then delete this value.
I use this part by John Resig (the creator of jQuery) to remove an element but it doesn't seem to listen to the location I give it
Array.prototype.remove = function(from, to) {
var rest = this.slice((to || from) + 1 || this.length);
this.length = from < 0 ? this.length + from : from;
return this.push.apply(this, rest);
};
this is how I use it
var elements = ['#1','#2','#3','#4']
var R1 = Math.floor(Math.random() * elements.length),
E1 = elements.slice(R1,1)
elements.remove(R1)
var R2 = Math.floor(Math.random() * elements.length),
E2 = elements.slice(R2,1)
elements.remove(R2)
var R3 = Math.floor(Math.random() * elements.length),
E3 = elements.slice(R3,1)
elements.remove(R3)
var R4 = Math.floor(Math.random() * elements.length),
E4 = elements.slice(R4,1)
The problem is the remove function, it doesn't work when removing a object on a specific location I believe.
