我已经创建了这个解决方案，我希望你觉得它有用:

const quantify = max => (n, i) => n * (+max.slice(0, max.length - i))

const add = (a, b) => a + b

const calc = s => s.
    split('.').
    map(quantify('1000000')).
    reduce(add, 0)

const sortVersions = unsortedVersions => unsortedVersions
    .map(version => ({ version, order: calc(version) }))
    .sort((a, b) => a.order - b.order)
    .reverse()
    .map(o => o.version)

2017答:

v1 = '20.0.12'; 
v2 = '3.123.12';

compareVersions(v1,v2) 
// return positive: v1 > v2, zero:v1 == v2, negative: v1 < v2 
function compareVersions(v1, v2) {
        v1= v1.split('.')
        v2= v2.split('.')
        var len = Math.max(v1.length,v2.length)
        /*default is true*/
        for( let i=0; i < len; i++)
            v1 = Number(v1[i] || 0);
            v2 = Number(v2[i] || 0);
            if (v1 !== v2) return v1 - v2 ;
            i++;
        }
        return 0;
    }

最简单的现代浏览器代码:

 function compareVersion2(ver1, ver2) {
      ver1 = ver1.split('.').map( s => s.padStart(10) ).join('.');
      ver2 = ver2.split('.').map( s => s.padStart(10) ).join('.');
      return ver1 <= ver2;
 }

这里的想法是比较数字，但以字符串的形式。为了使比较工作，两个字符串必须在相同的长度。所以:

"123" > "99"变成"123" > "099" 填充短数字“修复”比较

这里我用0填充每个部分，长度为10。然后使用简单的字符串比较来得到答案

例子:

var ver1 = '0.2.10', ver2=`0.10.2`
//become 
ver1 = '0000000000.0000000002.0000000010'
ver2 = '0000000000.0000000010.0000000002'
// then it easy to see that
ver1 <= ver2 // true

看看这篇博客文章。此函数适用于数字版本号。

function compVersions(strV1, strV2) {
  var nRes = 0
    , parts1 = strV1.split('.')
    , parts2 = strV2.split('.')
    , nLen = Math.max(parts1.length, parts2.length);

  for (var i = 0; i < nLen; i++) {
    var nP1 = (i < parts1.length) ? parseInt(parts1[i], 10) : 0
      , nP2 = (i < parts2.length) ? parseInt(parts2[i], 10) : 0;

    if (isNaN(nP1)) { nP1 = 0; }
    if (isNaN(nP2)) { nP2 = 0; }

    if (nP1 != nP2) {
      nRes = (nP1 > nP2) ? 1 : -1;
      break;
    }
  }

  return nRes;
};

compVersions('10', '10.0'); // 0
compVersions('10.1', '10.01.0'); // 0
compVersions('10.0.1', '10.0'); // 1
compVersions('10.0.1', '10.1'); // -1

你可以使用带有选项的String#localeCompare

sensitivity Which differences in the strings should lead to non-zero result values. Possible values are: "base": Only strings that differ in base letters compare as unequal. Examples: a ≠ b, a = á, a = A. "accent": Only strings that differ in base letters or accents and other diacritic marks compare as unequal. Examples: a ≠ b, a ≠ á, a = A. "case": Only strings that differ in base letters or case compare as unequal. Examples: a ≠ b, a = á, a ≠ A. "variant": Strings that differ in base letters, accents and other diacritic marks, or case compare as unequal. Other differences may also be taken into consideration. Examples: a ≠ b, a ≠ á, a ≠ A. The default is "variant" for usage "sort"; it's locale dependent for usage "search". numeric Whether numeric collation should be used, such that "1" < "2" < "10". Possible values are true and false; the default is false. This option can be set through an options property or through a Unicode extension key; if both are provided, the options property takes precedence. Implementations are not required to support this property.

var版本=[" 2.0.1”、“2.0”、“1.0”、“1.0.1”,“2.0.0.1”); 版本。sort((a, b) => a.localeCompare(b, undefined， {numeric: true，灵敏度:'base'})); console.log(版本);

一个非常简单的方法:

function compareVer(previousVersion, currentVersion) {
 try {
    const [prevMajor, prevMinor = 0, prevPatch = 0] = previousVersion.split('.').map(Number);
    const [curMajor, curMinor = 0, curPatch = 0] = currentVersion.split('.').map(Number);

    if (curMajor > prevMajor) {
      return 'major update';
    }
    if (curMajor < prevMajor) {
      return 'major downgrade';
    }
    if (curMinor > prevMinor) {
      return 'minor update';
    }
    if (curMinor < prevMinor) {
      return 'minor downgrade';
    }
    if (curPatch > prevPatch) {
      return 'patch update';
    }
    if (curPatch < prevPatch) {
      return 'patch downgrade';
    }
    return 'same version';
  } catch (e) {
    return 'invalid format';
  }
}

输出:

compareVer("3.1", "3.1.1") // patch update
compareVer("3.1.1", "3.2") // minor update
compareVer("2.1.1", "1.1.1") // major downgrade
compareVer("1.1.1", "1.1.1") // same version

比较不同条件下的功能:

const compareVer = (ver1, middle, ver2) => {
  const res = new Intl.Collator("en").compare(ver1, ver2)
  let comp

  switch (middle) {
    case "=":
      comp = 0 === res
      break

    case ">":
      comp = 1 === res
      break

    case ">=":
      comp = 1 === res || 0 === res
      break

    case "<":
      comp = -1 === res
      break

    case "<=":
      comp = -1 === res || 0 === res
      break
  }

  return comp
}

console.log(compareVer("1.0.2", "=", "1.0.2")) // true
console.log(compareVer("1.0.3", ">", "1.0.2")) // true
console.log(compareVer("1.0.1", ">=", "1.0.2")) // false
console.log(compareVer("1.0.3", ">=", "1.0.2")) // true
console.log(compareVer("1.0.1", "<", "1.0.2")) // true
console.log(compareVer("1.0.1", "<=", "1.0.2")) // true
