简单的代码给你

var ranges = [{"1-10":"Apple"},{"11-20":"Ball"},{"21-30":"Cat"}]

function getAns(input_number) {
  let result = null
  // handle input ranges
  for (let index in ranges) {
    for (let key in ranges[index]) {
      let min = key.split('-')[0]
      let max = key.split('-')[1]
      if (input_number >= min && input_number <= max) {
        result = ranges[index][key]
      }
    }
  }
  return result
}

console.log(getAns(12))
