Question

'3.0.11' > '3.0.9'这样的需求用JS怎么实现比较优雅

Answer 1

提供一个新思路

function compare(a,b) {

  var as = a.split('.')

  var bs = b.split('.')

  return new Date(as[0],as[1],as[2]) > new Date(bs[0],bs[1],bs[2])

}

compare('3.0.11','3.0.9')//true

compare('3.0.11','3.0.20')//false

compare('4.0.11','3.0.20')//true
