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
    }

const compareAppVersions = (firstVersion, secondVersion) => { const firstVersionArray = firstVersion.split(".").map(Number); const secondVersionArray = secondVersion.split(".").map(Number); const loopLength = Math.max( firstVersionArray.length, secondVersionArray.length ）; 对于(设I = 0;i < loopLength;+ + i) { const a = firstVersionArray[i] || 0; const b = secondVersionArray[i] || 0; If (a !== b) { 返回> b ?1: -1; ｝ ｝ 返回0; };

replace()函数只替换字符串中的第一个出现项。我们来替换。与,。然后全部删除。然后做，to。再次将其解析为float。

for(i=0; i<versions.length; i++) {
    v = versions[i].replace('.', ',');
    v = v.replace(/\./g, '');
    versions[i] = parseFloat(v.replace(',', '.'));
}

最后，排序:

versions.sort();

把它转换成一个数字，然后比较。 假设每个主要/次要/补丁使用不超过3个数字，并且没有标签 (像这个1.12.042)

const versionNumber = +versionString
  .split('.')
  .map(v => '000' + v)
  .map(v => v.slice(-3))
  .join('');

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
