js实现版本号的大小比较

版本号大小比较，如 1.3.5, 1.10.1 ，直接在sort上扩展一下就好了：

data.sort(function (a, b) {

var sources = a.sdk_version.split('.')

var dests = b.sdk_version.split(',')

var minL = Math.min(sources.length, dests.length)

var r = null

for (let i = 0; i < minL; i++) {

  if (sources[i] < dests[i]) {

    r = 1

    break

  } else if (sources[i] > dests[i]) {

    r = -1

    break

  } else if (i === minL && sources[i] === dests[i]) {

    r = 0

  }

}

return r

})
