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);
}

// Returns true if v1 is bigger than v2, and false if otherwise.
function isNewerThan(v1, v2) {
      v1=v1.split('.');
      v2=v2.split('.');
      for(var i = 0; i<Math.max(v1.length,v2.length); i++){
        if(v1[i] == undefined) return false; // If there is no digit, v2 is automatically bigger
        if(v2[i] == undefined) return true; // if there is no digit, v1 is automatically bigger
        if(v1[i] > v2[i]) return true;
        if(v1[i] < v2[i]) return false;
      }
      return false; // Returns false if they are equal
    }

一个非常简单的方法:

function compareVer(previousVersion, currentVersion) {
 try {
    const [prevMajor, prevMinor = 0, prevPatch = 0] = previousVersion.split('.').map(Number);
    const [curMajor, curMinor = 0, curPatch = 0] = currentVersion.split('.').map(Number);

    if (curMajor > prevMajor) {
      return 'major update';
    }
    if (curMajor < prevMajor) {
      return 'major downgrade';
    }
    if (curMinor > prevMinor) {
      return 'minor update';
    }
    if (curMinor < prevMinor) {
      return 'minor downgrade';
    }
    if (curPatch > prevPatch) {
      return 'patch update';
    }
    if (curPatch < prevPatch) {
      return 'patch downgrade';
    }
    return 'same version';
  } catch (e) {
    return 'invalid format';
  }
}

输出:

compareVer("3.1", "3.1.1") // patch update
compareVer("3.1.1", "3.2") // minor update
compareVer("2.1.1", "1.1.1") // major downgrade
compareVer("1.1.1", "1.1.1") // same version

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

我也遇到了版本比较的问题，但是版本可能包含任何内容(例如:不是点的分隔符，像rc1, rc2…)

我使用了这个方法，它基本上将版本字符串分为数字和非数字，并尝试根据类型进行比较。

function versionCompare(a,b) {
  av = a.match(/([0-9]+|[^0-9]+)/g)
  bv = b.match(/([0-9]+|[^0-9]+)/g)
  for (;;) {
    ia = av.shift();
    ib = bv.shift();
    if ( (typeof ia === 'undefined') && (typeof ib === 'undefined') ) { return 0; }
    if (typeof ia === 'undefined') { ia = '' }
    if (typeof ib === 'undefined') { ib = '' }

    ian = parseInt(ia);
    ibn = parseInt(ib);
    if ( isNaN(ian) || isNaN(ibn) ) {
      // non-numeric comparison
      if (ia < ib) { return -1;}
      if (ia > ib) { return 1;}
    } else {
      if (ian < ibn) { return -1;}
      if (ian > ibn) { return 1;}
    }
  }
}

对于某些情况，这里有一些假设，例如:"1.01" === "1.1"，或"1.8" < "1.71"。它无法管理“1.0.0-rc”。1" < "1.0.0"，由语义版本2.0.0指定

你可以遍历每个以句点分隔的字符并将其转换为int类型:

var parts = versionString.split('.');

for (var i = 0; i < parts.length; i++) {
  var value = parseInt(parts[i]);
  // do stuffs here.. perhaps build a numeric version variable?
}
