我根据Kons的想法做了这个，并针对Java版本“1.7.0_45”进行了优化。它只是一个将版本字符串转换为浮点数的函数。这是函数:

function parseVersionFloat(versionString) {
    var versionArray = ("" + versionString)
            .replace("_", ".")
            .replace(/[^0-9.]/g, "")
            .split("."),
        sum = 0;
    for (var i = 0; i < versionArray.length; ++i) {
        sum += Number(versionArray[i]) / Math.pow(10, i * 3);
    }
    console.log(versionString + " -> " + sum);
    return sum;
}

字符串“1.7.0_45”被转换为1.0070000450000001，这足以进行正常的比较。这里解释的错误:如何处理JavaScript中的浮点数精度?如果需要超过3个数字在任何部分，你可以改变除法数学。Pow (10, I * 3);;

输出如下所示:

1.7.0_45         > 1.007000045
ver 1.7.build_45 > 1.007000045
1.234.567.890    > 1.23456789

你可以遍历每个以句点分隔的字符并将其转换为int类型:

var parts = versionString.split('.');

for (var i = 0; i < parts.length; i++) {
  var value = parseInt(parts[i]);
  // do stuffs here.. perhaps build a numeric version variable?
}

2020年(大多数时候)正确的JavaScript答案

Nina Scholz在2020年3月和Sid Vishnoi在2020年4月都给出了现代的答案:

var versions = ["2.0.1", "2.0", "1.0", "1.0.1", "2.0.0.1"];

versions.sort((a, b) => 
   a.localeCompare(b, undefined, { numeric: true, sensitivity: 'base' })
);

console.log(versions);

localCompare已经存在一段时间了

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Intl/Collator/Collator

但是1.0a和1.0.1呢

localCompare不能解决这个问题，仍然返回1.0.1,1.0a

迈克尔·迪尔(Michael Deal)在他的(略长且复杂的)解决方案中已经在2013年解决了这个问题

他将数字转换为另一种进位，以便更好地排序

他的回答让我思考……

666 -不要用数字思考- 999

排序是基于ASCII值的字母数字排序，所以让我们(ab)使用ASCII作为“基”

我的解决方案是将1.0.2.1到b.a.c.b转换为bacb，然后排序

这解决了1.1 vs. 1.0.0.0.1: bb vs. baaab

立即用baa和bab符号解决了1.0a和1.0.1排序问题

转换是通过:

    const str = s => s.match(/(\d+)|[a-z]/g)
                      .map(c => c == ~~c ? String.fromCharCode(97 + c) : c);

=计算ASCII值0…999数字，否则连字母

1.0 > > >(“0”,“1”” " ] >>> [ " b”、“”、“”)

为了便于比较，没有必要使用.join("")将其连接到一个字符串。

Oneliner

const sortVersions=(x,v=s=>s.match(/(\d+)|[a-z]/g)
                            .map(c=>c==~~c?String.fromCharCode(97+c):c))
                    =>x.sort((a,b)=>v(b)<v(a)?1:-1)

测试代码片段:

function log(label,val){ document.body.append(label,String(val).replace(/,/g," - "),document.createElement("BR")); } let v = ["1.90.1", "1.9.1", "1.89", "1.090", "1.2", "1.0a", "1.0.1", "1.10", "1.0.0a"]; log('not sorted input :',v); v.sort((a, b) => a.localeCompare(b,undefined,{numeric:true,sensitivity:'base' })); log(' locale Compare :', v); // 1.0a AFTER 1.0.1 const str = s => s.match(/(\d+)|[a-z]/g) .map(c => c == ~~c ? String.fromCharCode(97 + c) : c); const versionCompare = (a, b) => { a = str(a); b = str(b); return b < a ? 1 : a == b ? 0 : -1; } v.sort(versionCompare); log('versionCompare:', v);

注意1.090是如何在两个结果中排序的。

我的代码不会解决一个答案中提到的001.012.001符号，但是localeCompare正确地解决了这部分挑战。

你可以结合这两种方法:

当涉及字母时，使用.localCompare或versionCompare进行排序

最终的JavaScript解决方案

const sortVersions = ( x, V = s => s.match(/[a-z]|\d+/g)。Map (c => c==~~c ?String.fromCharCode(97 + c): c) => x.sort((a, b) => (a + b).match(/[a-z]/) ？ V (b) < V (a) ?1: -1 : a.localeCompare(b, 0， {numeric: true})) 让v =[" 1.90.1”、“1.090”、“1.0”、“1.0.1”,“1.0.0a”,“1.0.0b”、“1.0.0.1”); console.log (sortVersions (v));

const compareAppVersions = (firstVersion, secondVersion) => { const firstVersionArray = firstVersion.split(".").map(Number); const secondVersionArray = secondVersion.split(".").map(Number); const loopLength = Math.max( firstVersionArray.length, secondVersionArray.length ）; 对于(设I = 0;i < loopLength;+ + i) { const a = firstVersionArray[i] || 0; const b = secondVersionArray[i] || 0; If (a !== b) { 返回> b ?1: -1; ｝ ｝ 返回0; };

下面是另一个简短的版本，适用于任何数量的子版本，填充零和偶数字母(1.0.0b3)

const compareVer = ((prep, repl) =>
{
  prep = t => ("" + t)
      //treat non-numerical characters as lower version
      //replacing them with a negative number based on charcode of first character
    .replace(/[^0-9\.]+/g, c => "." + (c.replace(/[\W_]+/, "").toLowerCase().charCodeAt(0) - 65536) + ".")
      //remove trailing "." and "0" if followed by non-numerical characters (1.0.0b);
    .replace(/(?:\.0+)*(\.-[0-9]+)(\.[0-9]+)?\.*$/g, "$1$2")
    .split('.');

  return (a, b, c, i, r) =>
  {
    a = prep(a);
    b = prep(b);
    for (i = 0, r = 0, c = Math.max(a.length, b.length); !r && i++ < c;)
    {
      r = -1 * ((a[i] = ~~a[i]) < (b[i] = ~~b[i])) + (a[i] > b[i]);
    }
    return r;
  }
})();

函数返回:

如果a = b则为0

1如果a > b

-1如果a < b

下面是一个版本，它对版本字符串进行排序，而不分配任何子字符串或数组。由于它分配的对象更少，GC要做的工作也就更少。

有一对分配(允许重用getVersionPart方法)，但是如果您对性能非常敏感，您可以扩展它以完全避免分配。

const compareVersionStrings : (a: string, b: string) => number = (a, b) =>
{
    var ia = {s:a,i:0}, ib = {s:b,i:0};
    while (true)
    {
        var na = getVersionPart(ia), nb = getVersionPart(ib);

        if (na === null && nb === null)
            return 0;
        if (na === null)
            return -1;
        if (nb === null)
            return 1;
        if (na > nb)
            return 1;
        if (na < nb)
            return -1;
    }
};

const zeroCharCode = '0'.charCodeAt(0);

const getVersionPart = (a : {s:string, i:number}) =>
{
    if (a.i >= a.s.length)
        return null;

    var n = 0;
    while (a.i < a.s.length)
    {
        if (a.s[a.i] === '.')
        {
            a.i++;
            break;
        }

        n *= 10;
        n += a.s.charCodeAt(a.i) - zeroCharCode;
        a.i++;
    }
    return n;
}
