以下是我的解决方案，适用于任何深度的任何版本。

自动处理数字+点问题。如果不是这样，函数存在，控制台日志将给出undefined而不是true, false或true。

自动处理尾随零问题。

任何可能的地方都存在自动继电器。

自动向后兼容旧浏览器。

function checkVersion (vv,vvv){ if(!(/^[0-9.]*$/.test(vv) && /^[0-9.]*$/.test(vvv))) return; va = vv.toString().split('.'); vb = vvv.toString().split('.'); length = Math.max(va.length, vb.length); for (i = 0; i < length; i++) { if ((va[i]|| 0) < (vb[i]|| 0) ) {return false; } } return true;} console.log(checkVersion('20.0.0.1' , '20.0.0.2')); console.log(checkVersion(20.0 , '20.0.0.2')); console.log(checkVersion('20.0.0.0.0' , 20)); console.log(checkVersion('20.0.0.0.1' , 20)); console.log(checkVersion('20.0.0-0.1' , 20));

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

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

1.0         < 1.0.1
