我的答案比这里的大多数答案都要简洁

/**
 * Compare two semver versions. Returns true if version A is greater than
 * version B
 * @param {string} versionA
 * @param {string} versionB
 * @returns {boolean}
 */
export const semverGreaterThan = function(versionA, versionB){
  var versionsA = versionA.split(/\./g),
    versionsB = versionB.split(/\./g)
  while (versionsA.length || versionsB.length) {
    var a = Number(versionsA.shift()), b = Number(versionsB.shift())
    if (a == b)
      continue
    return (a > b || isNaN(b))
  }
  return false
}

function versionCompare(version1, version2){
                var a = version1.split('.');
                var b = version2.split('.');
                for (var i = 0; i < a.length; ++i) {
                    a[i] = Number(a[i]);
                }
                for (var i = 0; i < b.length; ++i) {
                    b[i] = Number(b[i]);
                }
                var length=a.length;

                for(j=0; j<length; j++){
                    if(typeof b[j]=='undefined')b[j]=0;
                    if (a[j] > b[j]) return true;
                    else if(a[j] < b[j])return false;
                    if(j==length-1 && a[j] >= b[j])return true;
                }             

                return false;
            },

你可以使用JavaScript的localeCompare方法:

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

这里有一个例子:

"1.1".localeCompare("2.1.1"， undefined， {numeric: true}) => -1

"1.0.0".localeCompare("1.0"， undefined， {numeric: true}) =>

"1.0.0".localeCompare("1.0.0"， undefined， {numeric: true}) => 0

这是一个巧妙的技巧。如果您正在处理数值，在特定的值范围内，您可以为版本对象的每个级别分配一个值。例如，“largestValue”在这里被设置为0xFF，这为您的版本控制创建了一个非常“IP”的外观。

这也处理字母-数字版本(即1.2a < 1.2b)

// The version compare function
function compareVersion(data0, data1, levels) {
    function getVersionHash(version) {
        var value = 0;
        version = version.split(".").map(function (a) {
            var n = parseInt(a);
            var letter = a.replace(n, "");
            if (letter) {
                return n + letter[0].charCodeAt() / 0xFF;
            } else {
                return n;
            }
        });
        for (var i = 0; i < version.length; ++i) {
            if (levels === i) break;
            value += version[i] / 0xFF * Math.pow(0xFF, levels - i + 1);
        }
        return value;
    };
    var v1 = getVersionHash(data0);
    var v2 = getVersionHash(data1);
    return v1 === v2 ? -1 : v1 > v2 ? 0 : 1;
};
// Returns 0 or 1, correlating to input A and input B
// Direct match returns -1
var version = compareVersion("1.254.253", "1.254.253a", 3);

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));

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
