这适用于由句点分隔的任何长度的数字版本。只有当myVersion为>= minimumVersion时，它才返回true，假设版本1小于1.0，版本1.1小于1.1.0，以此类推。添加额外的条件应该相当简单，比如接受数字(只需转换为字符串)和十六进制，或者使分隔符动态(只需添加一个分隔符参数，然后将“。”替换为参数)

function versionCompare(myVersion, minimumVersion) {

    var v1 = myVersion.split("."), v2 = minimumVersion.split("."), minLength;   

    minLength= Math.min(v1.length, v2.length);

    for(i=0; i<minLength; i++) {
        if(Number(v1[i]) > Number(v2[i])) {
            return true;
        }
        if(Number(v1[i]) < Number(v2[i])) {
            return false;
        }           
    }

    return (v1.length >= v2.length);
}

下面是一些测试:

console.log(versionCompare("4.4.0","4.4.1"));
console.log(versionCompare("5.24","5.2"));
console.log(versionCompare("4.1","4.1.2"));
console.log(versionCompare("4.1.2","4.1"));
console.log(versionCompare("4.4.4.4","4.4.4.4.4"));
console.log(versionCompare("4.4.4.4.4.4","4.4.4.4.4"));
console.log(versionCompare("0","1"));
console.log(versionCompare("1","1"));
console.log(versionCompare("","1"));
console.log(versionCompare("10.0.1","10.1"));

这里有一个递归版本

function versionCompare(myVersion, minimumVersion) {
  return recursiveCompare(myVersion.split("."),minimumVersion.split("."),Math.min(myVersion.length, minimumVersion.length),0);
}

function recursiveCompare(v1, v2,minLength, index) {
  if(Number(v1[index]) < Number(v2[index])) {
    return false;
  }
  if(Number(v1[i]) < Number(v2[i])) {
    return true;
    }
  if(index === minLength) {
    return (v1.length >= v2.length);
  }
  return recursiveCompare(v1,v2,minLength,index+1);
}

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

这里找不到我想要的函数。所以我自己写了。这就是我的贡献。我希望有人觉得它有用。

优点:

处理任意长度的版本字符串。'1'或'1.1.1.1.1'。 如果没有指定，则默认为0。仅仅因为字符串更长并不意味着它是一个更大的版本。(“1”应与“1.0”和“1.0.0.0”相同。) 比较数字而不是字符串。('3'<'21'应为真。不是假的。) 不要把时间浪费在无用的比较上。(比较for ==) 你可以选择你自己的比较器。

缺点:

它不处理版本字符串中的字母。(我不知道这是怎么回事?)

我的代码，类似于Jon接受的答案:

function compareVersions(v1, comparator, v2) {
    "use strict";
    var comparator = comparator == '=' ? '==' : comparator;
    if(['==','===','<','<=','>','>=','!=','!=='].indexOf(comparator) == -1) {
        throw new Error('Invalid comparator. ' + comparator);
    }
    var v1parts = v1.split('.'), v2parts = v2.split('.');
    var maxLen = Math.max(v1parts.length, v2parts.length);
    var part1, part2;
    var cmp = 0;
    for(var i = 0; i < maxLen && !cmp; i++) {
        part1 = parseInt(v1parts[i], 10) || 0;
        part2 = parseInt(v2parts[i], 10) || 0;
        if(part1 < part2)
            cmp = 1;
        if(part1 > part2)
            cmp = -1;
    }
    return eval('0' + comparator + cmp);
}

例子:

compareVersions('1.2.0', '==', '1.2'); // true
compareVersions('00001', '==', '1.0.0'); // true
compareVersions('1.2.0', '<=', '1.2'); // true
compareVersions('2.2.0', '<=', '1.2'); // false

最简单的方法是使用localeCompare:

a.localeCompare(b, undefined, { numeric: true, sensitivity: 'base' })

这将返回:

0:版本字符串相等 1: a版本大于b版本 -1:版本b大于版本a

我必须比较我的扩展版本，但我没有 在这里找到一个可行的解决方案。在比较1.89 > 1.9或1.24.1 == 1.240.1时，几乎所有提议的期权都被打破了

这里，我从仅在最后的记录1.1 == 1.10和1.10.1 > 1.1.1中0下降的事实开始

compare_version = (new_version, old_version) => {
    new_version = new_version.split('.');
    old_version = old_version.split('.');
    for(let i = 0, m = Math.max(new_version.length, old_version.length); i<m; i++){
        //compare text
        let new_part = (i<m-1?'':'.') + (new_version[i] || 0)
        ,   old_part = (i<m-1?'':'.') + (old_version[i] || 0);
        //compare number (I don’t know what better)
      //let new_part = +((i<m-1?0:'.') + new_version[i]) || 0
      //,   old_part = +((i<m-1?0:'.') + old_version[i]) || 0;
        //console.log(new_part, old_part);
        if(old_part > new_part)return 0;    //change to -1 for sort the array
        if(new_part > old_part)return 1
    }
    return 0
};
compare_version('1.0.240.1','1.0.240.1');   //0
compare_version('1.0.24.1','1.0.240.1');    //0
compare_version('1.0.240.89','1.0.240.9');  //0
compare_version('1.0.24.1','1.0.24');       //1

我不是一个大专家，但我构建了简单的代码来比较两个版本，将第一个返回值更改为-1以对版本数组进行排序

['1.0.240', '1.0.24', '1.0.240.9', '1.0.240.89'].sort(compare_version)
//results ["1.0.24", "1.0.240", "1.0.240.89", "1.0.240.9"]

和短版本的比较全字符串

c=e=>e.split('.').map((e,i,a)=>e[i<a.length-1?'padStart':'padEnd'](5)).join('');

//results "    1    0  2409    " > "    1    0  24089   "

c('1.0.240.9')>c('1.0.240.89')              //true

如果您有意见或改进，请不要犹豫提出建议。

如果两个版本相等，函数将返回-1，如果第一个版本是最新版本，则返回0，而1表示第二个版本是最新版本。

let v1 = '12.0.1.0'
let v2 = '12.0.1'

let temp1 = v1.split('.');
let temp2 = v2.split('.');

console.log(compareVersion(temp1, temp2))


function compareVersion(version1, version2) {
    let flag = false;
    var compareResult;
    let maxLength = Math.max(version1.length, version2.length); 
    let minLength = Math.min(version1.length, version2.length);

    for (let i = 0; i < maxLength; ++i ) {
        let result = version1[i] - version2[i];
        if (result > 0) {
            flag = true;
            compareResult = 0;
            break;
        }
        else if (result < 0) {
            flag = true;
            compareResult = 1;
            break;
        }

        if (i === minLength) {
            if (version1.length > version1.length) {
                compareResult = version1[version1.length-1] > 0 ? '0' : '-1'
            }  else  {
                compareResult = version1[version2.length-1] > 0 ? '1' : '-1'
            }
            break;
        }
    }
    if (flag === false) {
        compareResult = -1;
    }
    return compareResult;
}
