如何让此脚本返回数字0-9而不是1-10

Question

我试图让数字0-9随机顺序洗牌。 EX：2,4,0,1,3,5,9,7,8,6 ...目前它始于1而不是0. 这就是我正在使用的 - （我对js的了解是min 。）

<script type="text/javascript" language="Javascript"> 
function pick(n, min, max){ 
    var values = [], i = max; 
    while(i >= min) values.push(i--); 
    var results = []; 
    var maxIndex = max; 
    for(i=1; i <= n; i++){ 
     maxIndex--; 
     var index = Math.floor(maxIndex * Math.random()); 
     results.push(values[index]); 
     values[index] = values[maxIndex]; 
    } 
    return results; 
} 
function go(){ 
    var running = true; 
    do{ 
     if(!confirm(pick(10, 0, 9))){ 
      running = false; 
     } 
    }while(running); 
} 

</script>

可能更有利于在这里创造出更多的功能，为便于阅读，更容易调试。

// Creates the array [min, min+1, ..., max-1, max] 
function createRange(min, max) { 
    var range = []; 
    while (min <= max) { 
    range.push(min); 
    min++; 
    } 
    return range; 
} 

// Fisher-Yates Shuffle from http://bost.ocks.org/mike/shuffle/ 
// but you can replace this with your own shuffler if you want 
function yatesShuffle(array) { 
    var m = array.length, t, i; 
    while (m) { 
    i = Math.floor(Math.random() * m--); 
    t = array[m]; 
    array[m] = array[i]; 
    array[i] = t; 
    } 
    return array; 
} 

// Pick `n` numbers from the range `[min, ..., max]`. 
// `n` must be less than or equal to `(max - min)`. 
function pick(n, min, max) { 
    var range = createRange(min, max); 
    var shuffled = yatesShuffle(range); 
    return shuffled.slice(0,n); 
} 

function go(){ 
    var running = true; 
    do{ 
     if(!confirm(pick(10, 0, 9))){ 
      running = false; 
     } 
    }while(running); 
}
