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。

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

这里有一个面向对象的有趣方法:

    function versionString(str) {
    var parts = str.split('.');
    this.product = parts.length > 0 ? parts[0] * 1 : 0;
    this.major = parts.length > 1 ? parts[1] * 1 : 0;
    this.minor = parts.length > 2 ? parts[2] * 1 : 0;
    this.build = parts.length > 3 ? parts[3] * 1 : 0;

    this.compareTo = function(vStr){
        vStr = this._isVersionString(vStr) ? vStr : new versionString(vStr);
        return this.compare(this, vStr);
    };

    this.toString = function(){
        return this.product + "." + this.major + "." + this.minor + "." + this.build;
    }

    this.compare = function (str1, str2) {
        var vs1 = this._isVersionString(str1) ? str1 : new versionString(str1);
        var vs2 = this._isVersionString(str2) ? str2 : new versionString(str2);

        if (this._compareNumbers(vs1.product, vs2.product) == 0) {
            if (this._compareNumbers(vs1.major, vs2.major) == 0) {
                if (this._compareNumbers(vs1.minor, vs2.minor) == 0) {
                    return this._compareNumbers(vs1.build, vs2.build);
                } else {
                    return this._compareNumbers(vs1.minor, vs2.minor);
                }
            } else {
                return this._compareNumbers(vs1.major, vs2.major);
            }
        } else {
            return this._compareNumbers(vs1.product, vs2.product);
        }
    };

    this._isVersionString = function (str) {
        return str !== undefined && str.build !== undefined;
    };

    this._compareNumbers = function (n1, n2) {
        if (n1 > n2) {
            return 1;
        } else if (n1 < n2) {
            return -1;
        } else {
            return 0;
        }
    };
}

还有一些测试:

var v1 = new versionString("1.0");
var v2 = new versionString("1.0.1");
var v3 = new versionString("2.0");
var v4 = new versionString("2.0.0.1");
var v5 = new versionString("2.0.1");


alert(v1.compareTo("1.4.2"));
alert(v3.compareTo(v1));
alert(v5.compareTo(v4));
alert(v4.compareTo(v5));
alert(v5.compareTo(v5));

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;
}

这是另一种递归算法。

这段代码只使用了Array。shift和递归，这意味着它可以在Internet Explorer 6+中运行。如果你有任何疑问，你可以访问我的GitHub页面。

(function(root, factory) {
  if (typeof exports === 'object') {
    return module.exports = factory();
  } else if (typeof define === 'function' && define.amd) {
    return define(factory);
  } else {
    return root.compareVer = factory();
  }
})(this, function() {
  'use strict';
  var _compareVer;
  _compareVer = function(newVer, oldVer) {
    var VER_RE, compareNum, isTrue, maxLen, newArr, newLen, newMatch, oldArr, oldLen, oldMatch, zerofill;
    VER_RE = /(\d+\.){1,9}\d+/;
    if (arguments.length !== 2) {
      return -100;
    }
    if (typeof newVer !== 'string') {
      return -2;
    }
    if (typeof oldVer !== 'string') {
      return -3;
    }
    newMatch = newVer.match(VER_RE);
    if (!newMatch || newMatch[0] !== newVer) {
      return -4;
    }
    oldMatch = oldVer.match(VER_RE);
    if (!oldMatch || oldMatch[0] !== oldVer) {
      return -5;
    }
    newVer = newVer.replace(/^0/, '');
    oldVer = oldVer.replace(/^0/, '');
    if (newVer === oldVer) {
      return 0;
    } else {
      newArr = newVer.split('.');
      oldArr = oldVer.split('.');
      newLen = newArr.length;
      oldLen = oldArr.length;
      maxLen = Math.max(newLen, oldLen);
      zerofill = function() {
        newArr.length < maxLen && newArr.push('0');
        oldArr.length < maxLen && oldArr.push('0');
        return newArr.length !== oldArr.length && zerofill();
      };
      newLen !== oldLen && zerofill();
      if (newArr.toString() === oldArr.toString()) {
        if (newLen > oldLen) {
          return 1;
        } else {
          return -1;
        }
      } else {
        isTrue = -1;
        compareNum = function() {
          var _new, _old;
          _new = ~~newArr.shift();
          _old = ~~oldArr.shift();
          _new > _old && (isTrue = 1);
          return _new === _old && newArr.length > 0 && compareNum();
        };
        compareNum();
        return isTrue;
      }
    }
  };
  return _compareVer;
});

好吧，我希望这段代码能帮助到一些人。

下面是测试。

console.log(compareVer('1.abc.2',"1.0.2")); //-4
console.log(compareVer('1.0.2',"1.abc.2")); //-5

进行这种比较的基本思想是使用Array。拆分以从输入字符串中获得部件数组，然后比较两个数组中的部件对;如果部分不相等，我们就知道哪个版本更小。

这里有一些重要的细节需要记住:

每对零件应该如何比较?这个问题想要从数字上进行比较，但是如果我们有不只是由数字组成的版本字符串(例如。“1.0”)? 如果一个版本字符串的部分比另一个多，会发生什么?很可能“1.0”应该被认为小于“1.0.1”，但是“1.0.0”呢?

下面是你可以直接使用的实现代码(要点和文档):

function versionCompare(v1, v2, options) {
    var lexicographical = options && options.lexicographical,
        zeroExtend = options && options.zeroExtend,
        v1parts = v1.split('.'),
        v2parts = v2.split('.');

    function isValidPart(x) {
        return (lexicographical ? /^\d+[A-Za-z]*$/ : /^\d+$/).test(x);
    }

    if (!v1parts.every(isValidPart) || !v2parts.every(isValidPart)) {
        return NaN;
    }

    if (zeroExtend) {
        while (v1parts.length < v2parts.length) v1parts.push("0");
        while (v2parts.length < v1parts.length) v2parts.push("0");
    }

    if (!lexicographical) {
        v1parts = v1parts.map(Number);
        v2parts = v2parts.map(Number);
    }

    for (var i = 0; i < v1parts.length; ++i) {
        if (v2parts.length == i) {
            return 1;
        }

        if (v1parts[i] == v2parts[i]) {
            continue;
        }
        else if (v1parts[i] > v2parts[i]) {
            return 1;
        }
        else {
            return -1;
        }
    }

    if (v1parts.length != v2parts.length) {
        return -1;
    }

    return 0;
}

这个版本自然地比较各个部分，不接受字符后缀，并认为“1.7”比“1.7.0”小。比较模式可以更改为字典式，短版本字符串可以使用可选的第三个参数自动填充零。

这里有一个运行“单元测试”的JSFiddle;这是一个稍微扩展的版本的ripper234的工作(谢谢)。

重要提示:此代码使用Array。map和Array。这意味着它将不会在9之前的IE版本中运行。如果你需要支持这些方法，你就必须为缺失的方法提供填充。
