希望将如下对象依据value进行排序，并且保持key与value对应

let obj = {ATTACK: 698462, AV: 4174, FILTER: 7589767, IPS: 1106719, SCAN: 1667425, …};

函数

    function objSortByVal(obj) {
      var keyArr = [],valArr = [];
      for (var key in obj) {
        keyArr.push(key);
        valArr.push(obj[key]);
      }
      for (var i = 0, len = valArr.length; i < len; i++) {
        for (var j = 0; j < len - i; j++) {
          var keyTemp, valTemp;
          if (valArr[j] < valArr[j + 1]) {
            valTemp = valArr[j];
            valArr[j] = valArr[j + 1];
            valArr[j+1] = valTemp;
            keyTemp = keyArr[j];
            keyArr[j] = keyArr[j + 1];
            keyArr[j+1] = keyTemp;
          }
        }
      }
      var newobj={};
      for(var i = 0;i<valArr.length;i++){
        newobj[keyArr[i]]=valArr[i];
      }
      return newobj;
    }

调用

objSortByVal(obj)
