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

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; };

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);
}

你可以使用带有选项的String#localeCompare

sensitivity Which differences in the strings should lead to non-zero result values. Possible values are: "base": Only strings that differ in base letters compare as unequal. Examples: a ≠ b, a = á, a = A. "accent": Only strings that differ in base letters or accents and other diacritic marks compare as unequal. Examples: a ≠ b, a ≠ á, a = A. "case": Only strings that differ in base letters or case compare as unequal. Examples: a ≠ b, a = á, a ≠ A. "variant": Strings that differ in base letters, accents and other diacritic marks, or case compare as unequal. Other differences may also be taken into consideration. Examples: a ≠ b, a ≠ á, a ≠ A. The default is "variant" for usage "sort"; it's locale dependent for usage "search". numeric Whether numeric collation should be used, such that "1" < "2" < "10". Possible values are true and false; the default is false. This option can be set through an options property or through a Unicode extension key; if both are provided, the options property takes precedence. Implementations are not required to support this property.

var版本=[" 2.0.1”、“2.0”、“1.0”、“1.0.1”,“2.0.0.1”); 版本。sort((a, b) => a.localeCompare(b, undefined， {numeric: true，灵敏度:'base'})); console.log(版本);

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();

我想为解决这个问题的轻量级库做广告:语义版本

可以同时使用面向对象(OO)和面向函数。它可以作为npm-package和现成的包文件使用。
