随机但只是在Chrome中 [英] Random but just in Chrome

问题描述

我有这个功能来创建一个随机数字范围。

I've this function to create a random range of numbers.

function randomRange(min, max) {
  return (new Array(++max-min))
  .join('.').split('.')
  .map(function(v,i){ return min+i; })
  .sort(function(){ return 0|Math.random()*max; });
}

它完美但仅限Chrome。所有其他浏览器由于某种原因变化很小...

It works perfect but only in Chrome. All other browsers have very little variation for some reason...

我在这里有一个简单的演示，所以你可以看到差异 http://jsfiddle.net/elclanrs/zZRda/ 。

I've a simple demo here so you can see the difference http://jsfiddle.net/elclanrs/zZRda/.

尽可能看到Chrome中的数字顺序大多是随机的，但在其他浏览器中没有太多变化，只有少数数字会改变，但它们看起来几乎相同。

As you can see the order of numbers in Chrome is mostly random but in other browsers there's not much variation, only a few numbers change place but it all looks almost the same.

现在检查在Chrome和其他浏览器中 http://jsbin.com/iyalax/3/edit 我会非常清楚地看到差异。

Now check http://jsbin.com/iyalax/3/edit in Chrome and other browsers and you'll see the difference very clearly.

为什么会发生这种情况？

Any ideas why this is happening?

编辑：我还有另一个 randomRange 函数在所有浏览器中运行正常，它只是更长且更丑，请检查 http://jsbin.com/iyalax/4/edit 以查看差异。

I've another randomRange function that works fine in all browsers, it's just longer and uglier, check http://jsbin.com/iyalax/4/edit to see the difference.

推荐答案

问题解决了！我在Hacker News找到了一个非常好的解决方案，它现在在所有浏览器中都很完美：

Problem solved! I found a pretty sweet solution at Hacker News, it works perfect in all browsers now:

function randomRange(min, max) {
  return (new Array(++max-min))
  .join('.').split('.')
  .map(function(v,i){ return min+i; })
  .map(function(v) { return [Math.random(), v]; })
  .sort().map(function(v) { return v[1]; });
}
