<script>
    let arr = {1: "3", 247: "1205", 360: "1582", 414: "0", 709: "512"}
    let keysSorted = Object.keys(arr).sort(function(a,b){
      return arr[a] - arr[b];
    });
    console.log("key",keysSorted)
    let normalArr = []
    for(let key in arr){
      normalArr.push(arr[key])
    }
    let sortArr = normalArr.sort();
    console.log("value", sortArr)
</script>

如果全是小于四位数方法是正确的
返回的结果是
["key", "414","1","709","247","360"]
["value", "0","1205","1582","3","512"]
