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

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

功能简单简短:

function isNewerVersion (oldVer, newVer) {
  const oldParts = oldVer.split('.')
  const newParts = newVer.split('.')
  for (var i = 0; i < newParts.length; i++) {
    const a = ~~newParts[i] // parse int
    const b = ~~oldParts[i] // parse int
    if (a > b) return true
    if (a < b) return false
  }
  return false
}

测试:

isNewerVersion('1.0', '2.0') // true
isNewerVersion('1.0', '1.0.1') // true
isNewerVersion('1.0.1', '1.0.10') // true
isNewerVersion('1.0.1', '1.0.1') // false
isNewerVersion('2.0', '1.0') // false
isNewerVersion('2', '1.0') // false
isNewerVersion('2.0.0.0.0.1', '2.1') // true
isNewerVersion('2.0.0.0.0.1', '2.0') // false

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);

在排序之前对版本进行预处理意味着parseInt不会被不必要地多次调用。 使用array# map类似于Michael Deal的建议，下面是我用来查找标准3部分semver的最新版本的排序:

var semvers = ["0.1.0", "1.0.0", "1.1.0", "1.0.5"]; var versions = semvers.map(function(semver) { return semver.split(".").map(function(part) { return parseInt(part); }); }); versions.sort(function(a, b) { if (a[0] < b[0]) return 1; else if (a[0] > b[0]) return -1; else if (a[1] < b[1]) return 1; else if (a[1] > b[1]) return -1; else if (a[2] < b[2]) return 1; else if (a[2] > b[2]) return -1; return 0; }); var newest = versions[0].join("."); console.log(newest); // "1.1.0"
