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);

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

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;
}

这个非常小，但非常快的比较函数接受每个段的任何长度和任何数字大小的版本号。

返回值: -如果a < b，则数字< 0 -如果是> b，则为> 0 如果a = b - 0

所以你可以使用它作为array。sort()的比较函数;

编辑:修正了版本剥离尾随零识别“1”和“1.0.0”相等的错误

function cmpVersions (a, b) { var i, diff; var regExStrip0 = /(\.0+)+$/; var segmentsA = a.replace(regExStrip0, '').split('.'); var segmentsB = b.replace(regExStrip0, '').split('.'); var l = Math.min(segmentsA.length, segmentsB.length); for (i = 0; i < l; i++) { diff = parseInt(segmentsA[i], 10) - parseInt(segmentsB[i], 10); if (diff) { return diff; } } return segmentsA.length - segmentsB.length; } // TEST console.log( ['2.5.10.4159', '1.0.0', '0.5', '0.4.1', '1', '1.1', '0.0.0', '2.5.0', '2', '0.0', '2.5.10', '10.5', '1.25.4', '1.2.15'].sort(cmpVersions)); // Result: // ["0.0.0", "0.0", "0.4.1", "0.5", "1.0.0", "1", "1.1", "1.2.15", "1.25.4", "2", "2.5.0", "2.5.10", "2.5.10.4159", "10.5"]

两个版本比较

const val = '1.2.3 5.4.3';
const arr = val.split(' ');
let obj = {};
for(let i = 0; i<2; i++) {
    const splitArr = arr[i].split('.')
    const reduced = splitArr.reduce((pre, 
    curr)=>parseInt(pre)+parseInt(curr));
    obj[i] = reduced;
}
if(obj[0]>obj[1]) {
    console.log(arr[0]);
} else {
    console.log(arr[1]);
}

我想为解决这个问题的轻量级库做广告:语义版本

可以同时使用面向对象(OO)和面向函数。它可以作为npm-package和现成的包文件使用。
