function randomize(objects){
var objTotalWeight = 0, objCWeight = 0, i;
for(i = 0; i < objects.length; i++){
objTotalWeight += objects[i][1];
}
var random = Math.floor(Math.random() * objTotalWeight);
for(i = 0; i < objects.length; i++){
objCWeight += objects[i][1];
if(random < objCWeight){
return objects[i][0];
}
}
}To use:
var pokemon = [
["Pikachu", 70], //70% chance
["Raichu", 20], //20% chance
["Pichu", 10] //10% chance
];
var result = randomize(pokemon);For best results, weights should add up to 100.
