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?
}

我已经创建了这个解决方案，我希望你觉得它有用:

https://runkit.com/ecancino/5f3c6c59593d23001485992e

const quantify = max => (n, i) => n * (+max.slice(0, max.length - i))

const add = (a, b) => a + b

const calc = s => s.
    split('.').
    map(quantify('1000000')).
    reduce(add, 0)

const sortVersions = unsortedVersions => unsortedVersions
    .map(version => ({ version, order: calc(version) }))
    .sort((a, b) => a.order - b.order)
    .reverse()
    .map(o => o.version)

我找到了最简单的方法来比较它们，但我不确定这是否是你想要的。

当我在控制台中运行下面的代码时，它是有意义的，并且使用sort()方法，我可以获得版本字符串的排序数组。它是根据字母顺序排列的。

"1.0" < "1.0.1" //true
var arr = ["1.0.1", "1.0", "3.2.0", "1.3"]
arr.sort();     //["1.0", "1.0.1", "1.3", "3.2.0"]
