javascript - 如何检查大于特定值的数组元素

问题描述

我有以下数组，我需要检查数组是否有任何AvgWT值

  1. 大于 15000 且小于 20000 则返回 50
  2. 大于 10000 且小于 15000 则返回 100
  3. 大于 5000 且小于 10000 则返回 150

我尝试了以下代码。

var arry = [{"TimeSlot":"8:00 am","AssistedC":0,"Abandons":0,"AvgWT":12152},{"TimeSlot":"8:15 am","AssistedC":0,"Abandons":0,"AvgWT":13942},{"TimeSlot":"8:30 am","AssistedC":0,"Abandons":0,"AvgWT":0},{"TimeSlot":"8:45 am","AssistedC":0,"Abandons":0,"AvgWT":0},{"TimeSlot":"9:00 am","AssistedC":0,"Abandons":0,"AvgWT":0},{"TimeSlot":"9:15 am","AssistedC":0,"Abandons":0,"AvgWT":0},{"TimeSlot":"6:30 pm","AssistedC":0,"Abandons":0,"AvgWT":0},{"TimeSlot":"6:45 pm","AssistedC":0,"Abandons":0,"AvgWT":0},{"TimeSlot":"7:00 pm","AssistedC":0,"Abandons":0,"AvgWT":0}];

function isArrayValueGreater(arry) {
   // var first = array[0];
    var first = arry[0]["AvgWaitTime"];
    return arry.every(function(element) {
        if(element["AvgWaitTime"]> 15000 &&  element["AvgWaitTime"]< 20000){
            return 50;
        }else if(element["AvgWaitTime"]> 10000 && element["AvgWaitTime"]<15000){
            return 100;
        }
    });
}

isValuesSameG = isArrayValueGreater(arry);

但它不能正常工作，我在这里做错了什么？

解决方案

如果我理解正确，您可以使用 .map() 方法。它将返回具有相同长度的新数组，包括匹配检查和结果。这是代码

const arry = [{"TimeSlot":"8:00 am","AssistedC":0,"Abandons":0,"AvgWT":12152},{"TimeSlot":"8:15 am","AssistedC":0,"Abandons":0,"AvgWT":13942},{"TimeSlot":"8:30 am","AssistedC":0,"Abandons":0,"AvgWT":0},{"TimeSlot":"8:45 am","AssistedC":0,"Abandons":0,"AvgWT":0},{"TimeSlot":"9:00 am","AssistedC":0,"Abandons":0,"AvgWT":0},{"TimeSlot":"9:15 am","AssistedC":0,"Abandons":0,"AvgWT":0},{"TimeSlot":"6:30 pm","AssistedC":0,"Abandons":0,"AvgWT":0},{"TimeSlot":"6:45 pm","AssistedC":0,"Abandons":0,"AvgWT":0},{"TimeSlot":"7:00 pm","AssistedC":0,"Abandons":0,"AvgWT":0}];

function checkIfMatchCondition({ AvgWT: value }) {
  if(value < 20000 && value > 15000)
    return 50
  else if(value < 15000 && value > 10000)
    return 100
  else if(value < 10000 && value > 5000)
    return 150
  return 0
}

const res = arry.map(checkIfMatchCondition);
console.log(res)

可以通过包含索引或具有附加属性的整个对象来改进它，但在原始帖子中没有足够的细节。
