Logic For A Loop

[baratheon]

I have a javascript array() with the names of the users as keys, and the number of entries they've submitted to a raffle as values. Based on that, I need to somehow select a random winner. At the moment I'm using something like this:

var rand_num = Math.floor(Math.random()*all_entriesCount);

var counter = 0;

$.each(all_entries, function(key, val){

if(counter == rand_num){

//set winner
return false;
//break out of loop
}

counter++;

});

But it doesn't account for the number of entries a user submitted. I'd like it so, the more entries a user submits, the higher his probability of winning. I'm guessing one way to do this would be to add another loop inside of the $.each loop?

Any ideas?

in the past, whenever I needed to randomly pick from a weighted array, a less elegant solution would be to create a new array that contained multiple entries for weighted array entries. like if an entry had 3 times the chance it would be in the new array 3 times. then take your random number from the length of that array.

there are more elegant solutions that can probably be found on google.
