Javascript骰子掷出多个数字

Question

我正在尝试创建一个骰子，在他确定为一个之前指示多个数字。我尝试了一种非常简单的方法，但没有奏效：这是我的代码：

<script>


//preload the six images first
var face0=new Image()
face0.src="http://www.unisg.bplaced.net/dices/d1.gif"
var face1=new Image()
face1.src="http://www.unisg.bplaced.net/dices/d2.gif"
var face2=new Image()
face2.src="http://www.unisg.bplaced.net/dices/d3.gif"
var face3=new Image()
face3.src="http://www.unisg.bplaced.net/dices/d4.gif"
var face4=new Image()
face4.src="http://www.unisg.bplaced.net/dices/d5.gif"
var face5=new Image()
face5.src="http://www.unisg.bplaced.net/dices/d6.gif"

function delay(time) {
  var d1 = new Date();
  var d2 = new Date();
  while (d2.valueOf() < d1.valueOf() + time) {
    d2 = new Date();
  }
}
</script>


<img src="http://www.unisg.bplaced.net/dices/d1.gif" name="mydice">
<form><br><br>
<input type="button" value="Throw dice!" onClick="throwdice(); throwdices();">
</form>

<script type="text/javascript">
function DoAllThese() {
throwdice(); 
throwdices();
}

function throwdice(){
delay(500); 
document.images["mydice"].src=eval("face"+5+".src"); 
delay(500); 
throwdices(); 
}

function throwdices(){
var randomdices=Math.round(Math.random()*4.5); 
delay(1000); 
document.images["mydice"].src=eval("face"+randomdices+".src"); 
}
</script>

我不确定如何对数字进行排序，以使其看起来像骰子在得到解决方案之前会旋转。

使用setInterval:

function throwdices() {
    var spins = 10;
    var curSpin = 0;
    var spinInterval = setInterval(function() {
        curSpin++;
        if (curSpin < spins) {
            var randomdices=Math.round(Math.random()*4.5);
            document.images["mydice"].src=eval("face"+randomdices+".src");
        } else {
            clearInterval(spinInterval);
            throwdice();
        }
    }, 500);
}
