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);

这实际上取决于版本控制系统背后的逻辑。每个数字代表什么，如何使用。

每个subversion是否是一个用于指定开发阶段的数字? 为0 1代表β 发布候选2个 3为(最终)发布

它是构建版本吗?您是否应用增量更新?

一旦了解了版本控制系统的工作原理，创建算法就变得很容易了。

如果您不允许在每个subversion中使用大于9的数字，则删除所有小数，但第一个小数将允许您进行直接比较。

如果允许在任何一种颠覆版本中使用大于9的数字，有几种方法可以比较它们。最明显的方法是将字符串按小数分割，然后比较每一列。

但是在不知道版本控制系统是如何工作的情况下，当版本1.0.2a发布时，实现像上面这样的过程可能会很麻烦。

你不能把它们转换成数字，然后按大小排序吗?在长度< 4的数的1后面加上0

在主机上玩:

$(["1.0.0.0", "1.0.1.0", "2.0.0.0", "2.0.0.1", "2.0.1", "3.0"]).each(function(i,e) {
    var n =   e.replace(/\./g,"");
    while(n.length < 4) n+="0" ; 
    num.push(  +n  )
});

版本越大，数字越大。 编辑:可能需要调整，以考虑更大的版本系列

我认为这是一个值得分享的实现，因为它简短，简单，但功能强大。请注意，它只使用数字比较。通常它会检查version2是否比version1晚，如果是，则返回true。假设您有version1: 1.1.1和version2: 1.1.2。它遍历两个版本的每个部分，将它们的部分相加如下:对于版本1(1 + 0.1)然后(1.1 + 0.01)，对于版本2(1 + 0.1)然后(1.1 + 0.02)。

function compareVersions(version1, version2) {

    version1 = version1.split('.');
    version2 = version2.split('.');

    var maxSubVersionLength = String(Math.max.apply(undefined, version1.concat(version2))).length;

    var reduce = function(prev, current, index) {

        return parseFloat(prev) + parseFloat('0.' + Array(index + (maxSubVersionLength - String(current).length)).join('0') + current);
    };

    return version1.reduce(reduce) < version2.reduce(reduce);
}

如果你想从版本列表中找到最新的版本，那么这可能是有用的:

function findLatestVersion(versions) {

    if (!(versions instanceof Array)) {
        versions = Array.prototype.slice.apply(arguments, [0]);
    }

    versions = versions.map(function(version) { return version.split('.'); });

    var maxSubVersionLength = String(Math.max.apply(undefined, Array.prototype.concat.apply([], versions))).length;

    var reduce = function(prev, current, index) {

        return parseFloat(prev) + parseFloat('0.' + Array(index + (maxSubVersionLength - String(current).length)).join('0') + current);
    };

    var sums = [];

    for (var i = 0; i < versions.length; i++) {
        sums.push(parseFloat(versions[i].reduce(reduce)));
    }

    return versions[sums.indexOf(Math.max.apply(undefined, sums))].join('.');
}

console.log(findLatestVersion('0.1000000.1', '2.0.0.10', '1.6.10', '1.4.3', '2', '2.0.0.1')); // 2.0.0.10
console.log(findLatestVersion(['0.1000000.1', '2.0.0.10', '1.6.10', '1.4.3', '2', '2.0.0.1'])); // 2.0.0.10

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

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
